31 Aug. 1989:
|
||
1. A(min(i,j)) now is translated correctly (where A is an array).
|
||
2. 7 and 8 character variable names are allowed (but elicit a
|
||
complaint under -ext).
|
||
3. LOGICAL*1 is treated as LOGICAL, with just one error message
|
||
per LOGICAL*1 statement (rather than one per variable declared
|
||
in that statement). [Note that LOGICAL*1 is not in Fortran 77.]
|
||
Like f77, f2c now allows the format in a read or write statement
|
||
to be an integer array.
|
||
|
||
5 Sept. 1989:
|
||
Fixed botch in argument passing of substrings of equivalenced
|
||
variables.
|
||
|
||
15 Sept. 1989:
|
||
Warn about incorrect code generated when a character-valued
|
||
function is not declared external and is passed as a parameter
|
||
(in violation of the Fortran 77 standard) before it is invoked.
|
||
Example:
|
||
|
||
subroutine foo(a,b)
|
||
character*10 a,b
|
||
call goo(a,b)
|
||
b = a(3)
|
||
end
|
||
|
||
18 Sept. 1989:
|
||
Complain about overlapping initializations.
|
||
|
||
20 Sept. 1989:
|
||
Warn about names declared EXTERNAL but never referenced;
|
||
include such names as externs in the generated C (even
|
||
though most C compilers will discard them).
|
||
|
||
24 Sept. 1989:
|
||
New option -w8 to suppress complaint when COMMON or EQUIVALENCE
|
||
forces word alignment of a double.
|
||
Under -A (for ANSI C), ensure that floating constants (terminated
|
||
by 'f') contain either a decimal point or an exponent field.
|
||
Repair bugs sometimes encountered with CHAR and ICHAR intrinsic
|
||
functions.
|
||
Restore f77's optimizations for copying and comparing character
|
||
strings of length 1.
|
||
Always assume floating-point valued routines in libF77 return
|
||
doubles, even under -R.
|
||
Repair occasional omission of arguments in routines having multiple
|
||
entry points.
|
||
Repair bugs in computing offsets of character strings involved
|
||
in EQUIVALENCE.
|
||
Don't omit structure qualification when COMMON variables are used
|
||
as FORMATs or internal files.
|
||
|
||
2 Oct. 1989:
|
||
Warn about variables that appear only in data stmts; don't emit them.
|
||
Fix bugs in character DATA for noncharacter variables
|
||
involved in EQUIVALENCE.
|
||
Treat noncharacter variables initialized (at least partly) with
|
||
character data as though they were equivalenced -- put out a struct
|
||
and #define the variables. This eliminates the hideous and nonportable
|
||
numeric values that were used to initialize such variables.
|
||
Treat IMPLICIT NONE as IMPLICIT UNDEFINED(A-Z) .
|
||
Quit when given invalid options.
|
||
|
||
8 Oct. 1989:
|
||
Modified naming scheme for generated intermediate variables;
|
||
more are recycled, fewer distinct ones used.
|
||
New option -W nn specifies nn characters/word for Hollerith
|
||
data initializing non-character variables.
|
||
Bug fix: x(i:min(i+10,j)) used to elicit "Can't handle opcode 31 yet".
|
||
Integer expressions of the form (i+const1) - (i+const2), where
|
||
i is a scalar integer variable, are now simplified to (const1-const2);
|
||
this leads to simpler translation of some substring expressions.
|
||
Initialize uninitialized portions of character string arrays to 0
|
||
rather than to blanks.
|
||
|
||
9 Oct. 1989:
|
||
New option -c to insert comments showing original Fortran source.
|
||
New option -g to insert line numbers of original Fortran source.
|
||
|
||
10 Oct. 1989:
|
||
! recognized as in-line comment delimiter (a la Fortran 88).
|
||
|
||
24 Oct. 1989:
|
||
New options to ease coping with systems that want the structs
|
||
that result from COMMON blocks to be defined just once:
|
||
-E causes uninitialized COMMON blocks to be declared Extern;
|
||
if Extern is undefined, f2c.h #defines it to be extern.
|
||
-ec causes a separate .c file to be emitted for each
|
||
uninitialized COMMON block: COMMON /ABC/ yields abc_com.c;
|
||
thus one can compile *_com.c into a library to ensure
|
||
precisely one definition.
|
||
-e1c is similar to -ec, except that everything goes into
|
||
one file, along with comments that give a sed script for
|
||
splitting the file into the pieces that -ec would give.
|
||
This is for use with netlib's "execute f2c" service (for which
|
||
-ec is coerced into -e1c, and the sed script will put everything
|
||
but the COMMON definitions into f2c_out.c ).
|
||
|
||
28 Oct. 1989:
|
||
Convert "i = i op ..." into "i op= ...;" even when i is a
|
||
dummy argument.
|
||
|
||
13 Nov. 1989:
|
||
Name integer constants (passed as arguments) c__... rather
|
||
than c_... so
|
||
common /c/stuff
|
||
call foo(1)
|
||
...
|
||
is translated correctly.
|
||
|
||
19 Nov. 1989:
|
||
Floating-point constants are now kept as strings unless they
|
||
are involved in constant expressions that get simplified. The
|
||
floating-point constants kept as strings can have arbitrarily
|
||
many significant figures and a very large exponent field (as
|
||
large as long int allows on the machine on which f2c runs).
|
||
Thus, for example, the body of
|
||
|
||
subroutine zot(x)
|
||
double precision x(6), pi
|
||
parameter (pi=3.1415926535897932384626433832795028841972)
|
||
x(1) = pi
|
||
x(2) = pi+1
|
||
x(3) = 9287349823749272.7429874923740978492734D-298374
|
||
x(4) = .89
|
||
x(5) = 4.0005
|
||
x(6) = 10D7
|
||
end
|
||
|
||
now gets translated into
|
||
|
||
x[1] = 3.1415926535897932384626433832795028841972;
|
||
x[2] = 4.1415926535897931;
|
||
x[3] = 9.2873498237492727429874923740978492734e-298359;
|
||
x[4] = (float).89;
|
||
x[5] = (float)4.0005;
|
||
x[6] = 1e8;
|
||
|
||
rather than the former
|
||
|
||
x[1] = 3.1415926535897931;
|
||
x[2] = 4.1415926535897931;
|
||
x[3] = 0.;
|
||
x[4] = (float)0.89000000000000003;
|
||
x[5] = (float)4.0004999999999997;
|
||
x[6] = 100000000.;
|
||
|
||
Recognition of f77 machine-constant intrinsics deleted, i.e.,
|
||
epbase, epprec, epemin, epemax, eptiny, ephuge, epmrsp.
|
||
|
||
22 Nov. 1989:
|
||
Workarounds for glitches on some Sun systems...
|
||
libf77: libF77/makefile modified to point out possible need
|
||
to compile libF77/main.c with -Donexit=on_exit .
|
||
libi77: libI77/wref.c (and libI77/README) modified so non-ANSI
|
||
systems can compile with USE_STRLEN defined, which will cause
|
||
sprintf(b = buf, "%#.*f", d, x);
|
||
n = strlen(b) + d1;
|
||
rather than
|
||
n = sprintf(b = buf, "%#.*f", d, x) + d1;
|
||
to be compiled.
|
||
|
||
26 Nov. 1989:
|
||
Longer names are now accepted (up to 50 characters); names may
|
||
contain underscores (in which case they will have two underscores
|
||
appended, to avoid clashes with library names).
|
||
|
||
28 Nov. 1989:
|
||
libi77 updated:
|
||
1. Allow 3 (or, on Crays, 4) digit exponents under format Ew.d .
|
||
2. Try to get things right on machines where ints have 16 bits.
|
||
|
||
29 Nov. 1989:
|
||
Supplied missing semicolon in parameterless subroutines that
|
||
have multiple entry points (all of them parameterless).
|
||
|
||
30 Nov. 1989:
|
||
libf77 and libi77 revised to use types from f2c.h.
|
||
f2c now types floating-point valued C library routines as "double"
|
||
rather than "doublereal" (for use with nonstandard C compilers for
|
||
which "double" is IEEE double extended).
|
||
|
||
1 Dec. 1989:
|
||
f2c.h updated to eliminate #defines rendered unnecessary (and,
|
||
indeed, dangerous) by change of 26 Nov. to long names possibly
|
||
containing underscores.
|
||
libi77 further revised: yesterday's change omitted two tweaks to fmt.h
|
||
(tweaks which only matter if float and real or double and doublereal are
|
||
different types).
|
||
|
||
2 Dec. 1989:
|
||
Better error message (than "bad tag") for NAMELIST, which no longer
|
||
inhibits C output.
|
||
|
||
4 Dec. 1989:
|
||
Allow capital letters in hex constants (f77 extension; e.g.,
|
||
x'a012BCd', X'A012BCD' and x'a012bcd' are all treated as the integer
|
||
167848909).
|
||
libi77 further revised: lio.c lio.h lread.c wref.c wrtfmt.c tweaked
|
||
again to allow float and real or double and doublereal to be different.
|
||
|
||
6 Dec. 1989:
|
||
Revised f2c.h -- required for the following...
|
||
Simpler looking translations for abs, min, max, using #defines in
|
||
revised f2c.h .
|
||
libi77: more corrections to types; additions for NAMELIST.
|
||
Corrected casts in some I/O calls.
|
||
Translation of NAMELIST; libi77 must still be revised. Currently
|
||
libi77 gives you a run-time error message if you attempt NAMELIST I/O.
|
||
|
||
7 Dec. 1989:
|
||
Fixed bug that prevented local integer variables that appear in DATA
|
||
stmts from being ASSIGNed statement labels.
|
||
Fillers (for DATA statements initializing EQUIVALENCEd variables and
|
||
variables in COMMON) typed integer rather than doublereal (for slightly
|
||
more portability, e.g. to Crays).
|
||
libi77: missing return values supplied in a few places; some tests
|
||
reordered for better working on the Cray.
|
||
libf77: better accuracy for complex divide, complex square root,
|
||
real mod function (casts to double; double temporaries).
|
||
|
||
9 Dec. 1989:
|
||
Fixed bug that caused needless (albeit harmless) empty lines to be
|
||
inserted in the C output when a comment line contained trailing blanks.
|
||
Further tweak to type of fillers: allow doublereal fillers if the
|
||
struct has doublereal data.
|
||
|
||
11 Dec. 1989:
|
||
Alteration of rule for producing external (C) names from names that
|
||
contain underscores. Now the external name is always obtained by
|
||
appending a pair of underscores.
|
||
|
||
12 Dec. 1989:
|
||
C production inhibited after most errors.
|
||
|
||
15 Dec. 1989:
|
||
Fixed bug in headers for subroutines having two or more character
|
||
strings arguments: the length arguments were reversed.
|
||
|
||
19 Dec. 1989:
|
||
f2c.h libf77 libi77: adjusted so #undefs in f2c.h should not foil
|
||
compilation of libF77 and libI77.
|
||
libf77: getenv_ adjusted to work with unsorted environments.
|
||
libi77: the iostat= specifier should now work right with internal I/O.
|
||
|
||
20 Dec. 1989:
|
||
f2c bugs fixed: In the absence of an err= specifier, the iostat=
|
||
specifier was generally set wrong. Character strings containing
|
||
explicit nulls (\0) were truncated at the first null.
|
||
Unlabeled DO loops recognized; must be terminated by ENDDO.
|
||
(Don't ask for CYCLE, EXIT, named DO loops, or DO WHILE.)
|
||
|
||
29 Dec. 1989:
|
||
Nested unlabeled DO loops now handled properly; new warning for
|
||
extraneous text at end of FORMAT.
|
||
|
||
30 Dec. 1989:
|
||
Fixed bug in translating dble(real(...)), dble(sngl(...)), and
|
||
dble(float(...)), where ... is either of type double complex or
|
||
is an expression requiring assignment to intermediate variables (e.g.,
|
||
dble(real(foo(x+1))), where foo is a function and x is a variable).
|
||
Regard nonblank label fields on continuation lines as an error.
|
||
|
||
3 Jan. 1990:
|
||
New option -C++ yields output that should be understood
|
||
by C++ compilers.
|
||
|
||
6 Jan. 1989:
|
||
-a now excludes variables that appear in a namelist from those
|
||
that it makes automatic. (As before, it also excludes variables
|
||
that appear in a common, data, equivalence, or save statement.)
|
||
The syntactically correct Fortran
|
||
read(*,i) x
|
||
end
|
||
now yields syntactically correct C (even though both the Fortran
|
||
and C are buggy -- no FORMAT has not been ASSIGNed to i).
|
||
|
||
7 Jan. 1990:
|
||
libi77: routines supporting NAMELIST added. Surrounding quotes
|
||
made optional when no ambiguity arises in a list or namelist READ
|
||
of a character-string value.
|
||
|
||
9 Jan. 1990:
|
||
f2c.src made available.
|
||
|
||
16 Jan. 1990:
|
||
New options -P to produce ANSI C or C++ prototypes for procedures
|
||
defined. Change to -A and -C++: f2c tries to infer prototypes for
|
||
invoked procedures unless the new -!P option is given. New warning
|
||
messages for inconsistent calling sequences among procedures within
|
||
a single file. Most of f2c/src is affected.
|
||
f2c.h: typedefs for procedure arguments added; netlib's f2c service
|
||
will insert appropriate typedefs for use with older versions of f2c.h.
|
||
|
||
17 Jan. 1990:
|
||
f2c/src: defs.h exec.c format.c proc.c putpcc.c version.c xsum0.out
|
||
updated. Castargs and protofile made extern in defs.h; exec.c
|
||
modified so superfluous else clauses are diagnosed; unused variables
|
||
omitted from declarations in format.c proc.c putpcc.c .
|
||
|
||
21 Jan. 1990:
|
||
No C emitted for procedures declared external but not referenced.
|
||
f2c.h: more new types added for use with -P.
|
||
New feature: f2c accepts as arguments files ending in .p or .P;
|
||
such files are assumed to be prototype files, such as produced by
|
||
the -P option. All prototype files are read before any Fortran files
|
||
and apply globally to all Fortran files. Suitable prototypes help f2c
|
||
warn about calling-sequence errors and can tell f2c how to type
|
||
procedures declared external but not explicitly typed; the latter is
|
||
mainly of interest for users of the -A and -C++ options. (Prototype
|
||
arguments are not available to netlib's "execute f2c" service.)
|
||
New option -it tells f2c to try to infer types of untyped external
|
||
arguments from their use as parameters to prototyped or previously
|
||
defined procedures.
|
||
f2c/src: many minor cleanups; most modules changed. Individual
|
||
files in f2c/src are now in "bundle" format. The former f2c.1 is
|
||
now f2c.1t; "f2c.1t from f2c" and "f2c.1t from f2c/src" are now the
|
||
same, as are "f2c.1 from f2c" and "f2c.1 from f2c/src". People who
|
||
do not obtain a new copy of "all from f2c/src" should at least add
|
||
fclose(sortfp);
|
||
after the call on do_init_data(outfile, sortfp) in format_data.c .
|
||
|
||
22 Jan. 1990:
|
||
Cleaner man page wording (thanks to Doug McIlroy).
|
||
-it now also applies to all untyped EXTERNAL procedures, not just
|
||
arguments.
|
||
|
||
23 Jan. 01:34:00 EST 1990:
|
||
Bug fixes: under -A and -C++, incorrect C was generated for
|
||
subroutines having multiple entries but no arguments.
|
||
Under -A -P, subroutines of no arguments were given prototype
|
||
calling sequence () rather than (void).
|
||
Character-valued functions elicited erroneous warning messages
|
||
about inconsistent calling sequences when referenced by another
|
||
procedure in the same file.
|
||
f2c.1t: omit first appearance of libF77.a in FILES section;
|
||
load order of libraries is -lF77 -lI77, not vice versa (bug
|
||
introduced in yesterday's edits); define .F macro for those whose
|
||
-man lacks it. (For a while after yesterday's fixes were posted,
|
||
f2c.1t was out of date. Sorry!)
|
||
|
||
23 Jan. 9:53:24 EST 1990:
|
||
Character substring expressions involving function calls having
|
||
character arguments (including the intrinsic len function) yielded
|
||
incorrect C.
|
||
Procedures defined after invocation (in the same file) with
|
||
conflicting argument types also got an erroneous message about
|
||
the wrong number of arguments.
|
||
|
||
24 Jan. 11:44:00 EST 1990:
|
||
Bug fixes: -p omitted #undefs; COMMON block names containing
|
||
underscores had their C names incorrectly computed; a COMMON block
|
||
having the name of a previously defined procedure wreaked havoc;
|
||
if all arguments were .P files, f2c tried reading the second as a
|
||
Fortran file.
|
||
New feature: -P emits comments showing COMMON block lengths, so one
|
||
can get warnings of incompatible COMMON block lengths by having f2c
|
||
read .P (or .p) files. Now by running f2c twice, first with -P -!c
|
||
(or -P!c), then with *.P among the arguments, you can be warned of
|
||
inconsistent COMMON usage, and COMMON blocks having inconsistent
|
||
lengths will be given the maximum length. (The latter always did
|
||
happen within each input file; now -P lets you extend this behavior
|
||
across files.)
|
||
|
||
26 Jan. 16:44:00 EST 1990:
|
||
Option -it made less aggressive: untyped external procedures that
|
||
are invoked are now typed by the rules of Fortran, rather than by
|
||
previous use of procedures to which they are passed as arguments
|
||
before being invoked.
|
||
Option -P now includes information about references, i.e., called
|
||
procedures, in the prototype files (in the form of special comments).
|
||
This allows iterative invocations of f2c to infer more about untyped
|
||
external names, particularly when multiple Fortran files are involved.
|
||
As usual, there are some obscure bug fixes:
|
||
1. Repair of erroneous warning messages about inconsistent number of
|
||
arguments that arose when a character dummy parameter was discovered
|
||
to be a function or when multiple entry points involved character
|
||
variables appearing in a previous entry point.
|
||
2. Repair of memory fault after error msg about "adjustable character
|
||
function".
|
||
3. Under -U, allow MAIN_ as a subroutine name (in the same file as a
|
||
main program).
|
||
4. Change for consistency: a known function invoked as a subroutine,
|
||
then as a function elicits a warning rather than an error.
|
||
|
||
26 Jan. 22:32:00 EST 1990:
|
||
Fixed two bugs that resulted in incorrect C for substrings, within
|
||
the body of a character-valued function, of the function's name, when
|
||
those substrings were arguments to another function (even implicitly,
|
||
as in character-string assignment).
|
||
|
||
28 Jan. 18:32:00 EST 1990:
|
||
libf77, libi77: checksum files added; "make check" looks for
|
||
transmission errors. NAMELIST read modified to allow $ rather than &
|
||
to precede a namelist name, to allow $ rather than / to terminate
|
||
input where the name of another variable would otherwise be expected,
|
||
and to regard all nonprinting ASCII characters <= ' ' as spaces.
|
||
|
||
29 Jan. 02:11:00 EST 1990:
|
||
"fc from f2c" added.
|
||
-it option made the default; -!it turns it off. Type information is
|
||
now updated in a previously missed case.
|
||
-P option tweaked again; message about when rerunning f2c may change
|
||
prototypes or declarations made more accurate.
|
||
New option -Ps implies -P and returns exit status 4 if rerunning
|
||
f2c -P with prototype inputs might change prototypes or declarations.
|
||
Now you can execute a crude script like
|
||
|
||
cat *.f >zap.F
|
||
rm -f zap.P
|
||
while :; do
|
||
f2c -Ps -!c zap.[FP]
|
||
case $? in 4) ;; *) break;; esac
|
||
done
|
||
|
||
to get a file zap.P of the best prototypes f2c can determine for *.f .
|
||
|
||
Jan. 29 07:30:21 EST 1990:
|
||
Forgot to check for error status when setting return code 4 under -Ps;
|
||
error status (1, 2, 3, or, for caught signal, 126) now takes precedence.
|
||
|
||
Jan 29 14:17:00 EST 1990:
|
||
Incorrect handling of
|
||
open(n,'filename')
|
||
repaired -- now treated as
|
||
open(n,file='filename')
|
||
(and, under -ext, given an error message).
|
||
New optional source file memset.c for people whose systems don't
|
||
provide memset, memcmp, and memcpy; #include <string.h> in mem.c
|
||
changed to #include "string.h" so BSD people can create a local
|
||
string.h that simply says #include <strings.h> .

Jan 30 10:34:00 EST 1990:
|
||
Fix erroneous warning at end of definition of a procedure with
|
||
character arguments when the procedure had previously been called with
|
||
a numeric argument instead of a character argument. (There were two
|
||
warnings, the second one incorrectly complaining of a wrong number of
|
||
arguments.)
|
||
|
||
Jan 30 16:29:41 EST 1990:
|
||
Fix case where -P and -Ps erroneously reported another iteration
|
||
necessary. (Only harm is the extra iteration.)
|
||
|
||
Feb 3 01:40:00 EST 1990:
|
||
Supply semicolon occasionally omitted under -c .
|
||
Try to force correct alignment when numeric variables are initialized
|
||
with character data (a non-standard and non-portable practice). You
|
||
must use the -W option if your code has such data statements and is
|
||
meant to run on a machine with other than 4 characters/word; e.g., for
|
||
code meant to run on a Cray, you would specify -W8 .
|
||
Allow parentheses around expressions in output lists (in write and
|
||
print statements).
|
||
Rename source files so their names are <= 12 characters long
|
||
(so there's room to append .Z and still have <= 14 characters);
|
||
renamed files: formatdata.c niceprintf.c niceprintf.h safstrncpy.c .
|
||
f2c material made available by anonymous ftp from research.att.com
|
||
(look in dist/f2c ).
|
||
|
||
Feb 3 03:49:00 EST 1990:
|
||
Repair memory fault that arose from use (in an assignment or
|
||
call) of a non-argument variable declared CHARACTER*(*).
|
||
|
||
Feb 9 01:35:43 EST 1990:
|
||
Fix erroneous error msg about bad types in
|
||
subroutine foo(a,adim)
|
||
dimension a(adim)
|
||
integer adim
|
||
Fix improper passing of character args (and possible memory fault)
|
||
in the expression part of a computed goto.
|
||
Fix botched calling sequences in array references involving
|
||
functions having character args.
|
||
Fix memory fault caused by invocation of character-valued functions
|
||
of no arguments.
|
||
Fix botched calling sequence of a character*1-valued function
|
||
assigned to a character*1 variable.
|
||
Fix bug in error msg for inconsistent number of args in prototypes.
|
||
Allow generation of C output despite inconsistencies in prototypes,
|
||
but give exit code 8.
|
||
Simplify include logic (by removing some bogus logic); never
|
||
prepend "/usr/include/" to file names.
|
||
Minor cleanups (that should produce no visible change in f2c's
|
||
behavior) in intr.c parse.h main.c defs.h formatdata.c p1output.c .
|
||
|
||
Feb 10 00:19:38 EST 1990:
|
||
Insert (integer) casts when floating-point expressions are used
|
||
as subscripts.
|
||
Make SAVE stmt (with no variable list) override -a .
|
||
Minor cleanups: change field to Field in struct Addrblock (for the
|
||
benefit of buggy C compilers); omit system("/bin/cp ...") in misc.c .
|
||
|
||
Feb 13 00:39:00 EST 1990:
|
||
Error msg fix in gram.dcl: change "cannot make %s parameter"
|
||
to "cannot make into parameter".
|
||
|
||
Feb 14 14:02:00 EST 1990:
|
||
Various cleanups (invisible on systems with 4-byte ints), thanks
|
||
to Dave Regan: vaxx.c eliminated; %d changed to %ld various places;
|
||
external names adjusted for the benefit of stupid systems (that ignore
|
||
case and recognize only 6 significant characters in external names);
|
||
buffer shortened in xsum.c (e.g. for MS-DOS); fopen modes distinguish
|
||
text and binary files; several unused functions eliminated; missing
|
||
arg supplied to an unlikely fatalstr invocation.
|
||
|
||
Thu Feb 15 19:15:53 EST 1990:
|
||
More cleanups (invisible on systems with 4 byte ints); casts inserted
|
||
so most complaints from cyntax(1) and lint(1) go away; a few (int)
|
||
versus (long) casts corrected.
|
||
|
||
Fri Feb 16 19:55:00 EST 1990:
|
||
Recognize and translate unnamed Fortran 8x do while statements.
|
||
Fix bug that occasionally caused improper breaking of character
|
||
strings.
|
||
New error message for attempts to provide DATA in a type-declaration
|
||
statement.
|
||
|
||
Sat Feb 17 11:43:00 EST 1990:
|
||
Fix infinite loop clf -> Fatal -> done -> clf after I/O error.
|
||
Change "if (addrp->vclass = CLPROC)" to "if (addrp->vclass == CLPROC)"
|
||
in p1_addr (in p1output.c); this was probably harmless.
|
||
Move a misplaced } in lex.c (which slowed initkey()).
|
||
Thanks to Gary Word for pointing these things out.
|
||
|
||
Sun Feb 18 18:07:00 EST 1990:
|
||
Detect overlapping initializations of arrays and scalar variables
|
||
in previously missed cases.
|
||
Treat logical*2 as logical (after issuing a warning).
|
||
Don't pass string literals to p1_comment().
|
||
Correct a cast (introduced 16 Feb.) in gram.expr; this matters e.g.
|
||
on a Cray.
|
||
Attempt to isolate UNIX-specific things in sysdep.c (a new source
|
||
file). Unless sysdep.c is compiled with SYSTEM_SORT defined, the
|
||
intermediate files created for DATA statements are now sorted in-core
|
||
without invoking system().
|
||
|
||
Tue Feb 20 16:10:35 EST 1990:
|
||
Move definition of binread and binwrite from init.c to sysdep.c .
|
||
Recognize Fortran 8x tokens < <= == >= > <> as synonyms for
|
||
.LT. .LE. .EQ. .GE. .GT. .NE.
|
||
Minor cleanup in putpcc.c: fully remove simoffset().
|
||
More discussion of system dependencies added to libI77/README.
|
||
|
||
Tue Feb 20 21:44:07 EST 1990:
|
||
Minor cleanups for the benefit of EBCDIC machines -- try to remove
|
||
the assumption that 'a' through 'z' are contiguous. (Thanks again to
|
||
Gary Word.) Also, change log2 to log_2 (shouldn't be necessary).
|
||
|
||
Wed Feb 21 06:24:56 EST 1990:
|
||
Fix botch in init.c introduced in previous change; only matters
|
||
to non-ASCII machines.
|
||
|
||
Thu Feb 22 17:29:12 EST 1990:
|
||
Allow several entry points to mention the same array. Protect
|
||
parameter adjustments with if's (for the case that an array is not
|
||
an argument to all entrypoints).
|
||
Under -u, allow
|
||
subroutine foo(x,n)
|
||
real x(n)
|
||
integer n
|
||
Compute intermediate variables used to evaluate dimension expressions
|
||
at the right time. Example previously mistranslated:
|
||
subroutine foo(x,k,m,n)
|
||
real x(min(k,m,n))
|
||
...
|
||
write(*,*) x
|
||
Detect duplicate arguments. (The error msg points to the first
|
||
executable stmt -- not wonderful, but not worth fixing.)
|
||
Minor cleanup of min/max computation (sometimes slightly simpler).
|
||
|
||
Sun Feb 25 09:39:01 EST 1990:
|
||
Minor tweak to multiple entry points: protect parameter adjustments
|
||
with if's only for (array) args that do not appear in all entry points.
|
||
Minor tweaks to format.c and io.c (invisible unless your compiler
|
||
complained at the duplicate #defines of IOSUNIT and IOSFMT or at
|
||
comparisons of p1gets(...) with NULL).
|
||
|
||
Sun Feb 25 18:40:10 EST 1990:
|
||
Fix bug introduced Feb. 22: if a subprogram contained DATA and the
|
||
first executable statement was labeled, then the label got lost.
|
||
(Just change INEXEC to INDATA in p1output.c; it occurs just once.)
|
||
|
||
Mon Feb 26 17:45:10 EST 1990:
|
||
Fix bug in handling of " and ' in comments.
|
||
|
||
Wed Mar 28 01:43:06 EST 1990:
|
||
libI77:
|
||
1. Repair nasty I/O bug: opening two files and closing the first
|
||
(after possibly reading or writing it), then writing the second caused
|
||
the last buffer of the second to be lost.
|
||
2. Formatted reads of logical values treated all letters other than
|
||
t or T as f (false).
|
||
libI77 files changed: err.c rdfmt.c Version.c
|
||
(Request "libi77 from f2c" -- you can't get these files individually.)
|
||
|
||
f2c itself:
|
||
Repair nasty bug in translation of
|
||
ELSE IF (condition involving complicated abs, min, or max)
|
||
-- auxiliary statements were emitted at the wrong place.
|
||
Supply semicolon previously omitted from the translation of a label
|
||
(of a CONTINUE) immediately preceding an ELSE IF or an ELSE. This
|
||
bug made f2c produce invalid C.
|
||
Correct a memory fault that occurred (on some machines) when the
|
||
error message "adjustable dimension on non-argument" should be given.
|
||
Minor tweaks to remove some harmless warnings by overly chatty C
|
||
compilers.
|
||
Argument arays having constant dimensions but a variable lower bound
|
||
(e.g., x(n+1:n+3)) had a * omitted from scalar arguments involved in
|
||
the array offset computation.
|
||
|
||
Wed Mar 28 18:47:59 EST 1990:
|
||
libf77: add exit(0) to end of main [return(0) encounters a Cray bug]
|
||
|
||
Sun Apr 1 16:20:58 EDT 1990:
|
||
Avoid dereferencing null when processing equivalences after an error.
|
||
|
||
Fri Apr 6 08:29:49 EDT 1990:
|
||
Calls involving alternate return specifiers omitted processing
|
||
needed for things like min, max, abs, and // (concatenation).
|
||
INTEGER*2 PARAMETERs were treated as INTEGER*4.
|
||
Convert some O(n^2) parsing to O(n).
|
||
|
||
Tue Apr 10 20:07:02 EDT 1990:
|
||
When inconsistent calling sequences involve differing numbers of
|
||
arguments, report the first differing argument rather than the numbers
|
||
of arguments.
|
||
Fix bug under -a: formatted I/O in which either the unit or the
|
||
format was a local character variable sometimes resulted in invalid C
|
||
(a static struct initialized with an automatic component).
|
||
Improve error message for invalid flag after elided -.
|
||
Complain when literal table overflows, rather than infinitely
|
||
looping. (The complaint mentions the new and otherwise undocumented
|
||
-NL option for specifying a larger literal table.)
|
||
New option -h for forcing strings to word (or, with -hd, double-word)
|
||
boundaries where possible.
|
||
Repair a bug that could cause improper splitting of strings.
|
||
Fix bug (cast of c to doublereal) in
|
||
subroutine foo(c,r)
|
||
double complex c
|
||
double precision r
|
||
c = cmplx(r,real(c))
|
||
end
|
||
New include file "sysdep.h" has some things from defs.h (and
|
||
elsewhere) that one may need to modify on some systems.
|
||
Some large arrays that were previously statically allocated are now
|
||
dynamically allocated when f2c starts running.
|
||
f2c/src files changed:
|
||
README cds.c defs.h f2c.1 f2c.1t format.c formatdata.c init.c
|
||
io.c lex.c main.c makefile mem.c misc.c names.c niceprintf.c
|
||
output.c parse_args.c pread.c put.c putpcc.c sysdep.h
|
||
version.c xsum0.out
|
||
|
||
Wed Apr 11 18:27:12 EDT 1990:
|
||
Fix bug in argument consistency checking of character, complex, and
|
||
double complex valued functions. If the same source file contained a
|
||
definition of such a function with arguments not explicitly typed,
|
||
then subsequent references to the function might get erroneous
|
||
warnings of inconsistent calling sequences.
|
||
Tweaks to sysdep.h for partially ANSI systems.
|
||
New options -kr and -krd cause f2c to use temporary variables to
|
||
enforce Fortran evaluation-order rules with pernicious, old-style C
|
||
compilers that apply the associative law to floating-point operations.
|
||
|
||
Sat Apr 14 15:50:15 EDT 1990:
|
||
libi77: libI77 adjusted to allow list-directed and namelist I/O
|
||
of internal files; bug in namelist I/O of logical and character arrays
|
||
fixed; list input of complex numbers adjusted to permit d or D to
|
||
denote the start of the exponent field of a component.
|
||
f2c itself: fix bug in handling complicated lower-bound
|
||
expressions for character substrings; e.g., min and max did not work
|
||
right, nor did function invocations involving character arguments.
|
||
Switch to octal notation, rather than hexadecimal, for nonprinting
|
||
characters in character and string constants.
|
||
Fix bug (when neither -A nor -C++ was specified) in typing of
|
||
external arguments of type complex, double complex, or character:
|
||
subroutine foo(c)
|
||
external c
|
||
complex c
|
||
now results in
|
||
/* Complex */ int (*c) ();
|
||
(as, indeed, it once did) rather than
|
||
complex (*c) ();
|
||
|
||
Sat Apr 14 22:50:39 EDT 1990:
|
||
libI77/makefile: updated "make check" to omit lio.c
|
||
lib[FI]77/makefile: trivial change: define CC = cc, reference $(CC).
|
||
(Request, e.g., "libi77 from f2c" -- you can't ask for individual
|
||
files from lib[FI]77.)
|
||
|
||
Wed Apr 18 00:56:37 EDT 1990:
|
||
Move declaration of atof() from defs.h to sysdep.h, where it is
|
||
now not declared if stdlib.h is included. (NeXT's stdlib.h has a
|
||
#define atof that otherwise wreaks havoc.)
|
||
Under -u, provide a more intelligible error message (than "bad tag")
|
||
for an attempt to define a function without specifying its type.
|
||
|
||
Wed Apr 18 17:26:27 EDT 1990:
|
||
Recognize \v (vertical tab) in Hollerith as well as quoted strings;
|
||
add recognition of \r (carriage return).
|
||
New option -!bs turns off recognition of escapes in character strings
|
||
(\0, \\, \b, \f, \n, \r, \t, \v).
|
||
Move to sysdep.c initialization of some arrays whose initialization
|
||
assumed ASCII; #define Table_size in sysdep.h rather than using
|
||
hard-coded 256 in allocating arrays of size 1 << (bits/byte).
|
||
|
||
Thu Apr 19 08:13:21 EDT 1990:
|
||
Warn when escapes would make Hollerith extend beyond statement end.
|
||
Omit max() definition from misc.c (should be invisible except on
|
||
systems that erroneously #define max in stdlib.h).
|
||
|
||
Mon Apr 23 22:24:51 EDT 1990:
|
||
When producing default-style C (no -A or -C++), cast switch
|
||
expressions to (int).
|
||
Move "-lF77 -lI77 -lm -lc" to link_msg, defined in sysdep.c .
|
||
Add #define scrub(x) to sysdep.h, with invocations in format.c and
|
||
formatdata.c, so that people who have systems like VMS that would
|
||
otherwise create multiple versions of intermediate files can
|
||
#define scrub(x) unlink(x)
|
||
|
||
Tue Apr 24 18:28:36 EDT 1990:
|
||
Pass string lengths once rather than twice to a function of character
|
||
arguments involved in comparison of character strings of length 1.
|
||
|
||
Fri Apr 27 13:11:52 EDT 1990:
|
||
Fix bug that made f2c gag on concatenations involving char(...) on
|
||
some systems.
|
||
|
||
Sat Apr 28 23:20:16 EDT 1990:
|
||
Fix control-stack bug in
|
||
if(...) then
|
||
else if (complicated condition)
|
||
else
|
||
endif
|
||
(where the complicated condition causes assignment to an auxiliary
|
||
variable, e.g., max(a*b,c)).
|
||
|
||
Mon Apr 30 13:30:10 EDT 1990:
|
||
Change fillers for DATA with holes from substructures to arrays
|
||
(in an attempt to make things work right with C compilers that have
|
||
funny padding rules for substructures, e.g., Sun C compilers).
|
||
Minor cleanup of exec.c (should not affect generated C).
|
||
|
||
Mon Apr 30 23:13:51 EDT 1990:
|
||
Fix bug in handling return values of functions having multiple
|
||
entry points of differing return types.
|
||
|
||
Sat May 5 01:45:18 EDT 1990:
|
||
Fix type inference bug in
|
||
subroutine foo(x)
|
||
call goo(x)
|
||
end
|
||
subroutine goo(i)
|
||
i = 3
|
||
end
|
||
Instead of warning of inconsistent calling sequences for goo,
|
||
f2c was simply making i a real variable; now i is correctly
|
||
typed as an integer variable, and f2c issues an error message.
|
||
Adjust error messages issued at end of declarations so they
|
||
don't blame the first executable statement.
|
||
|
||
Sun May 6 01:29:07 EDT 1990:
|
||
Fix bug in -P and -Ps: warn when the definition of a subprogram adds
|
||
information that would change prototypes or previous declarations.
|
||
|
||
Thu May 10 18:09:15 EDT 1990:
|
||
Fix further obscure bug with (default) -it: inconsistent calling
|
||
sequences and I/O statements could interact to cause a memory fault.
|
||
Example:
|
||
SUBROUTINE FOO
|
||
CALL GOO(' Something') ! Forgot integer first arg
|
||
END
|
||
SUBROUTINE GOO(IUNIT,MSG)
|
||
CHARACTER*(*)MSG
|
||
WRITE(IUNIT,'(1X,A)') MSG
|
||
END
|
||
|
||
Fri May 11 16:49:11 EDT 1990:
|
||
Under -!c, do not delete any .c files (when there are errors).
|
||
Avoid dereferencing 0 when a fatal error occurs while reading
|
||
Fortran on stdin.
|
||
|
||
Wed May 16 18:24:42 EDT 1990:
|
||
f2c.ps made available.
|
||
|
||
Mon Jun 4 12:53:08 EDT 1990:
|
||
Diagnose I/O units of invalid type.
|
||
Add specific error msg about dummy arguments in common.
|
||
|
||
Wed Jun 13 12:43:17 EDT 1990:
|
||
Under -A, supply a missing "[1]" for CHARACTER*1 variables that appear
|
||
both in a DATA statement and in either COMMON or EQUIVALENCE.
|
||
|
||
Mon Jun 18 16:58:31 EDT 1990:
|
||
Trivial updates to f2c.ps . ("Fortran 8x" --> "Fortran 90"; omit
|
||
"(draft)" from "(draft) ANSI C".)
|
||
|
||
Tue Jun 19 07:36:32 EDT 1990:
|
||
Fix incorrect code generated for ELSE IF(expression involving
|
||
function call passing non-constant substring).
|
||
Under -h, preserve the property that strings are null-terminated
|
||
where possible.
|
||
Remove spaces between # and define in lex.c output.c parse.h .
|
||
|
||
Mon Jun 25 07:22:59 EDT 1990:
|
||
Minor tweak to makefile to reduce unnecessary recompilations.
|
||
|
||
Tue Jun 26 11:49:53 EDT 1990:
|
||
Fix unintended truncation of some integer constants on machines
|
||
where casting a long to (int) may change the value. E.g., when f2c
|
||
ran on machines with 16-bit ints, "i = 99999" was being translated
|
||
to "i = -31073;".
|
||
|
||
Wed Jun 27 11:05:32 EDT 1990:
|
||
Arrange for CHARACTER-valued PARAMETERs to honor their length
|
||
specifications. Allow CHAR(nn) in expressions defining such PARAMETERs.
|
||
|
||
Fri Jul 20 09:17:30 EDT 1990:
|
||
Avoid dereferencing 0 when a FORMAT statement has no label.
|
||
|
||
Thu Jul 26 11:09:39 EDT 1990:
|
||
Remarks about VOID and binread,binwrite added to README.
|
||
Tweaks to parse_args: should be invisible unless your compiler
|
||
complained at (short)*store.
|
||
|
||
Thu Aug 2 02:07:58 EDT 1990:
|
||
f2c.ps: change the first line of page 5 from
|
||
include stuff
|
||
to
|
||
include 'stuff'
|
||
|
||
Tue Aug 14 13:21:24 EDT 1990:
|
||
libi77: libI77 adjusted to treat tabs as spaces in list input.
|
||
|
||
Fri Aug 17 07:24:53 EDT 1990:
|
||
libi77: libI77 adjusted so a blank='ZERO' clause (upper case Z)
|
||
in an open of a currently open file works right.
|
||
|
||
Tue Aug 28 01:56:44 EDT 1990:
|
||
Fix bug in warnings of inconsistent calling sequences: if an
|
||
argument to a subprogram was never referenced, then a previous
|
||
invocation of the subprogram (in the same source file) that
|
||
passed something of the wrong type for that argument did not
|
||
elicit a warning message.
|
||
|
||
Thu Aug 30 09:46:12 EDT 1990:
|
||
libi77: prevent embedded blanks in list output of complex values;
|
||
omit exponent field in list output of values of magnitude between
|
||
10 and 1e8; prevent writing stdin and reading stdout or stderr;
|
||
don't close stdin, stdout, or stderr when reopening units 5, 6, 0.
|
||
|
||
Tue Sep 4 12:30:57 EDT 1990:
|
||
Fix bug in C emitted under -I2 or -i2 for INTEGER*4 FUNCTION.
|
||
Warn of missing final END even if there are previous errors.
|
||
|
||
Fri Sep 7 13:55:34 EDT 1990:
|
||
Remark about "make xsum.out" and "make f2c" added to README.
|
||
|
||
Tue Sep 18 23:50:01 EDT 1990:
|
||
Fix null dereference (and, on some systems, writing of bogus *_com.c
|
||
files) under -ec or -e1c when a prototype file (*.p or *.P) describes
|
||
COMMON blocks that do not appear in the Fortran source.
|
||
libi77:
|
||
Add some #ifdef lines (#ifdef MSDOS, #ifndef MSDOS) to avoid
|
||
references to stat and fstat on non-UNIX systems.
|
||
On UNIX systems, add component udev to unit; decide that old
|
||
and new files are the same iff both the uinode and udev components
|
||
of unit agree.
|
||
When an open stmt specifies STATUS='OLD', use stat rather than
|
||
access (on UNIX systems) to check the existence of the file (in case
|
||
directories leading to the file have funny permissions and this is
|
||
a setuid or setgid program).
|
||
|
||
Thu Sep 27 16:04:09 EDT 1990:
|
||
Supply missing entry for Impldoblock in blksize array of cpexpr
|
||
(in expr.c). No examples are known where this omission caused trouble.
|
||
|
||
Tue Oct 2 22:58:09 EDT 1990:
|
||
libf77: test signal(...) == SIG_IGN rather than & 01 in main().
|
||
libi77: adjust rewind.c so two successive rewinds after a write
|
||
don't clobber the file.
|
||
|
||
Thu Oct 11 18:00:14 EDT 1990:
|
||
libi77: minor cleanups: add #include "fcntl.h" to endfile.c, err.c,
|
||
open.c; adjust g_char in util.c for segmented memories; in f_inqu
|
||
(inquire.c), define x appropriately when MSDOS is defined.
|
||
|
||
Mon Oct 15 20:02:11 EDT 1990:
|
||
Add #ifdef MSDOS pointer adjustments to mem.c; treat NAME= as a
|
||
synonym for FILE= in OPEN statements.
|
||
|
||
Wed Oct 17 16:40:37 EDT 1990:
|
||
libf77, libi77: minor cleanups: _cleanup() and abort() invocations
|
||
replaced by invocations of sig_die in main.c; some error messages
|
||
previously lost in buffers will now appear.
|
||
|
||
Mon Oct 22 16:11:27 EDT 1990:
|
||
libf77: separate sig_die from main (for folks who don't want to use
|
||
the main in libF77).
|
||
libi77: minor tweak to comments in README.
|
||
|
||
Fri Nov 2 13:49:35 EST 1990:
|
||
Use two underscores rather than one in generated temporary variable
|
||
names to avoid conflict with COMMON names. f2c.ps updated to reflect
|
||
this change and the NAME= extension introduced 15 Oct.
|
||
Repair a rare memory fault in io.c .
|
||
|
||
Mon Nov 5 16:43:55 EST 1990:
|
||
libi77: changes to open.c (and err.c): complain if an open stmt
|
||
specifies new= and the file already exists (as specified by Fortrans 77
|
||
and 90); allow file= to be omitted in open stmts and allow
|
||
status='replace' (Fortran 90 extensions).
|
||
|
||
Fri Nov 30 10:10:14 EST 1990:
|
||
Adjust malloc.c for unusual systems whose sbrk() can return values
|
||
not properly aligned for doubles.
|
||
Arrange for slightly more helpful and less repetitive warnings for
|
||
non-character variables initialized with character data; these warnings
|
||
are (still) suppressed by -w66.
|
||
|
||
Fri Nov 30 15:57:59 EST 1990:
|
||
Minor tweak to README (about changing VOID in f2c.h).
|
||
|
||
Mon Dec 3 07:36:20 EST 1990:
|
||
Fix spelling of "character" in f2c.1t.
|
||
|
||
Tue Dec 4 09:48:56 EST 1990:
|
||
Remark about link_msg and libf2c added to f2c/README.
|
||
|
||
Thu Dec 6 08:33:24 EST 1990:
|
||
Under -U, render label nnn as L_nnn rather than Lnnn.
|
||
|
||
Fri Dec 7 18:05:00 EST 1990:
|
||
Add more names from f2c.h (e.g. integer, real) to the c_keywords
|
||
list of names to which an underscore is appended to avoid confusion.
|
||
|
||
Mon Dec 10 19:11:15 EST 1990:
|
||
Minor tweaks to makefile (./xsum) and README (binread/binwrite).
|
||
libi77: a few modifications for POSIX systems; meant to be invisible
|
||
elsewhere.
|
||
|
||
Sun Dec 16 23:03:16 EST 1990:
|
||
Fix null dereference caused by unusual erroneous input, e.g.
|
||
call foo('abc')
|
||
end
|
||
subroutine foo(msg)
|
||
data n/3/
|
||
character*(*) msg
|
||
end
|
||
(Subroutine foo is illegal because the character statement comes after a
|
||
data statement.)
|
||
Use decimal rather than hex constants in xsum.c (to prevent
|
||
erroneous warning messages about constant overflow).
|
||
|
||
Mon Dec 17 12:26:40 EST 1990:
|
||
Fix rare extra underscore in character length parameters passed
|
||
for multiple entry points.
|
||
|
||
Wed Dec 19 17:19:26 EST 1990:
|
||
Allow generation of C despite error messages about bad alignment
|
||
forced by equivalence.
|
||
Allow variable-length concatenations in I/O statements, such as
|
||
open(3, file=bletch(1:n) // '.xyz')
|
||
|
||
Fri Dec 28 17:08:30 EST 1990:
|
||
Fix bug under -p with formats and internal I/O "units" in COMMON,
|
||
as in
|
||
COMMON /FIGLEA/F
|
||
CHARACTER*20 F
|
||
F = '(A)'
|
||
WRITE (*,FMT=F) 'Hello, world!'
|
||
END
|
||
|
||
Tue Jan 15 12:00:24 EST 1991:
|
||
Fix bug when two equivalence groups are merged, the second with
|
||
nonzero offset, and the result is then merged into a common block.
|
||
Example:
|
||
INTEGER W(3), X(3), Y(3), Z(3)
|
||
COMMON /ZOT/ Z
|
||
EQUIVALENCE (W(1),X(1)), (X(2),Y(1)), (Z(3),X(1))
|
||
***** W WAS GIVEN THE WRONG OFFSET
|
||
Recognize Fortran 90's optional NML= in NAMELIST READs and WRITEs.
|
||
(Currently NML= and FMT= are treated as synonyms -- there's no
|
||
error message if, e.g., NML= specifies a format.)
|
||
libi77: minor adjustment to allow internal READs from character
|
||
string constants in read-only memory.
|
||
|
||
Fri Jan 18 22:56:15 EST 1991:
|
||
Add comment to README about needing to comment out the typedef of
|
||
size_t in sysdep.h on some systems, e.g. Sun 4.1.
|
||
Fix misspelling of "statement" in an error message in lex.c
|
||
|
||
Wed Jan 23 00:38:48 EST 1991:
|
||
Allow hex, octal, and binary constants to have the qualifying letter
|
||
(z, x, o, or b) either before or after the quoted string containing the
|
||
digits. For now this change will not be reflected in f2c.ps .
|
||
|
||
Tue Jan 29 16:23:45 EST 1991:
|
||
Arrange for character-valued statement functions to give results of
|
||
the right length (that of the statement function's name).
|
||
|
||
Wed Jan 30 07:05:32 EST 1991:
|
||
More tweaks for character-valued statement functions: an error
|
||
check and an adjustment so a right-hand side of nonconstant length
|
||
(e.g., a substring) is handled right.
|
||
|
||
Wed Jan 30 09:49:36 EST 1991:
|
||
Fix p1_head to avoid printing (char *)0 with %s.
|
||
|
||
Thu Jan 31 13:53:44 EST 1991:
|
||
Add a test after the cleanup call generated for I/O statements with
|
||
ERR= or END= clauses to catch the unlikely event that the cleanup
|
||
routine encounters an error.
|
||
|
||
Mon Feb 4 08:00:58 EST 1991:
|
||
Minor cleanup: omit unneeded jumps and labels from code generated for
|
||
some NAMELIST READs and WRITEs with IOSTAT=, ERR=, and/or END=.
|
||
|
||
Tue Feb 5 01:39:36 EST 1991:
|
||
Change Mktemp to mktmp (for the benefit of systems so brain-damaged
|
||
that they do not distinguish case in external names -- and that for
|
||
some reason want to load mktemp). Try to get xsum0.out right this
|
||
time (it somehow didn't get updated on 4 Feb. 1991).
|
||
Add note to libi77/README about adjusting the interpretation of
|
||
RECL= specifiers in OPENs for direct unformatted I/O.
|
||
|
||
Thu Feb 7 17:24:42 EST 1991:
|
||
New option -r casts values of REAL functions, including intrinsics,
|
||
to REAL. This only matters for unportable code like
|
||
real r
|
||
r = asin(1.)
|
||
if (r .eq. asin(1.)) ...
|
||
[The behavior of such code varies with the Fortran compiler used --
|
||
and sometimes is affected by compiler options.] For now, the man page
|
||
at the end of f2c.ps is the only part of f2c.ps that reflects this new
|
||
option.
|
||
|
||
Fri Feb 8 18:12:51 EST 1991:
|
||
Cast pointer differences passed as arguments to the appropriate type.
|
||
This matters, e.g., with MSDOS compilers that yield a long pointer
|
||
difference but have int == short.
|
||
Disallow nonpositive dimensions.
|
||
|
||
Fri Feb 15 12:24:15 EST 1991:
|
||
Change %d to %ld in sprintf call in putpower in putpcc.c.
|
||
Free more memory (e.g. allowing translation of larger Fortran
|
||
files under MS-DOS).
|
||
Recognize READ (character expression) and WRITE (character expression)
|
||
as formatted I/O with the format given by the character expression.
|
||
Update year in Notice.
|
||
|
||
Sat Feb 16 00:42:32 EST 1991:
|
||
Recant recognizing WRITE(character expression) as formatted output
|
||
-- Fortran 77 is not symmetric in its syntax for READ and WRITE.
|
||
|
||
Mon Mar 4 15:19:42 EST 1991:
|
||
Fix bug in passing the real part of a complex argument to an intrinsic
|
||
function. Omit unneeded parentheses in nested calls to intrinsics.
|
||
Example:
|
||
subroutine foo(x, y)
|
||
complex y
|
||
x = exp(sin(real(y))) + exp(imag(y))
|
||
end
|
||
|
||
Fri Mar 8 15:05:42 EST 1991:
|
||
Fix a comment in expr.c; omit safstrncpy.c (which had bugs in
|
||
cases not used by f2c).
|
||
|
||
Wed Mar 13 02:27:23 EST 1991:
|
||
Initialize firstmemblock->next in mem_init in mem.c . [On most
|
||
systems it was fortuituously 0, but with System V, -lmalloc could
|
||
trip on this missed initialization.]
|
||
|
||
Wed Mar 13 11:47:42 EST 1991:
|
||
Fix a reference to freed memory.
|
||
|
||
Wed Mar 27 00:42:19 EST 1991:
|
||
Fix a memory fault caused by such illegal Fortran as
|
||
function foo
|
||
x = 3
|
||
logical foo ! declaration among executables
|
||
foo=.false. ! used to suffer memory fault
|
||
end
|
||
|
||
Fri Apr 5 08:30:31 EST 1991:
|
||
Fix loss of % in some format expressions, e.g.
|
||
write(*,'(1h%)')
|
||
Fix botch introduced 27 March 1991 that caused subroutines with
|
||
multiple entry points to have extraneous declarations of ret_val.
|
||
|
||
Fri Apr 5 12:44:02 EST 1991
|
||
Try again to omit extraneous ret_val declarations -- this morning's
|
||
fix was sometimes wrong.
|
||
|
||
Mon Apr 8 13:47:06 EDT 1991:
|
||
Arrange for s_rnge to have the right prototype under -A -C .
|
||
|
||
Wed Apr 17 13:36:03 EDT 1991:
|
||
New fatal error message for apparent invocation of a recursive
|
||
statement function.
|
||
|
||
Thu Apr 25 15:13:37 EDT 1991:
|
||
F2c and libi77 adjusted so NAMELIST works with -i2. (I forgot
|
||
about -i2 when adding NAMELIST.) This required a change to f2c.h
|
||
(that only affects NAMELIST I/O under -i2.) Man-page description of
|
||
-i2 adjusted to reflect that -i2 stores array lengths in short ints.
|
||
|
||
Fri Apr 26 02:54:41 EDT 1991:
|
||
Libi77: fix some bugs in NAMELIST reading of multi-dimensional arrays
|
||
(file rsne.c).
|
||
|
||
Thu May 9 02:13:51 EDT 1991:
|
||
Omit a trailing space in expr.c (could cause a false xsum value if
|
||
a mailer drops the trailing blank).
|
||
|
||
Thu May 16 13:14:59 EDT 1991:
|
||
Libi77: increase LEFBL in lio.h to overcome a NeXT bug.
|
||
Tweak for compilers that recognize "nested" comments: inside comments,
|
||
turn /* into /+ (as well as */ into +/).
|
||
|
||
Sat May 25 11:44:25 EDT 1991:
|
||
libf77: s_rnge: declare line long int rather than int.
|
||
|
||
Fri May 31 07:51:50 EDT 1991:
|
||
libf77: system_: officially return status.
|
||
|
||
Mon Jun 17 16:52:53 EDT 1991:
|
||
Minor tweaks: omit unnecessary declaration of strcmp (that caused
|
||
trouble on a system where strcmp was a macro) from misc.c; add
|
||
SHELL = /bin/sh to makefiles.
|
||
Fix a dereference of null when a CHARACTER*(*) declaration appears
|
||
(illegally) after DATA. Complain only once per subroutine about
|
||
declarations appearing after DATA.
|
||
|
||
Mon Jul 1 00:28:13 EDT 1991:
|
||
Add test and error message for illegal use of subroutine names, e.g.
|
||
SUBROUTINE ZAP(A)
|
||
ZAP = A
|
||
END
|
||
|
||
Mon Jul 8 21:49:20 EDT 1991:
|
||
Issue a warning about things like
|
||
integer i
|
||
i = 'abc'
|
||
(which is treated as i = ichar('a')). [It might be nice to treat 'abc'
|
||
as an integer initialized (in a DATA statement) with 'abc', but
|
||
other matters have higher priority.]
|
||
Render
|
||
i = ichar('A')
|
||
as
|
||
i = 'A';
|
||
rather than
|
||
i = 65;
|
||
(which assumes ASCII).
|
||
|
||
Fri Jul 12 07:41:30 EDT 1991:
|
||
Note added to README about erroneous definitions of __STDC__ .
|
||
|
||
Sat Jul 13 13:38:54 EDT 1991:
|
||
Fix bugs in double type convesions of complex values, e.g.
|
||
sngl(real(...)) or dble(real(...)) (where ... is complex).
|
||
|
||
Mon Jul 15 13:21:42 EDT 1991:
|
||
Fix bug introduced 8 July 1991 that caused erroneous warnings
|
||
"ichar([first char. of] char. string) assumed for conversion to numeric"
|
||
when a subroutine had an array of character strings as an argument.
|
||
|
||
Wed Aug 28 01:12:17 EDT 1991:
|
||
Omit an unused function in format.c, an unused variable in proc.c .
|
||
Under -r8, promote complex to double complex (as the man page claims).
|
||
|
||
Fri Aug 30 17:19:17 EDT 1991:
|
||
f2c.ps updated: slightly expand description of intrinsics and,or,xor,
|
||
not; add mention of intrinsics lshift, rshift; add note about f2c
|
||
accepting Fortran 90 inline comments (starting with !); update Cobalt
|
||
Blue address.
|
||
|
||
Tue Sep 17 07:17:33 EDT 1991:
|
||
libI77: err.c and open.c modified to use modes "rb" and "wb"
|
||
when (f)opening unformatted files; README updated to point out
|
||
that it may be necessary to change these modes to "r" and "w"
|
||
on some non-ANSI systems.
|
||
|
||
Tue Oct 15 10:25:49 EDT 1991:
|
||
Minor tweaks that make some PC compilers happier: insert some
|
||
casts, add args to signal functions.
|
||
Change -g to emit uncommented #line lines -- and to emit more of them;
|
||
update fc, f2c.1, f2c.1t, f2c.ps to reflect this.
|
||
Change uchar to Uchar in xsum.c .
|
||
Bring gram.c up to date.
|
||
|
||
Thu Oct 17 09:22:05 EDT 1991:
|
||
libi77: README, fio.h, sue.c, uio.c changed so the length field
|
||
in unformatted sequential records has type long rather than int
|
||
(unless UIOLEN_int is #defined). This is for systems where sizeof(int)
|
||
can vary, depending on the compiler or compiler options.
|
||
|
||
Thu Oct 17 13:42:59 EDT 1991:
|
||
libi77: inquire.c: when MSDOS is defined, don't strcmp units[i].ufnm
|
||
when it is NULL.
|
||
|
||
Fri Oct 18 15:16:00 EDT 1991:
|
||
Correct xsum0.out in "all from f2c/src" (somehow botched on 15 Oct.).
|
||
|
||
Tue Oct 22 18:12:56 EDT 1991:
|
||
Fix memory fault when a character*(*) argument is used (illegally)
|
||
as a dummy variable in the definition of a statement function. (The
|
||
memory fault occurred when the statement function was invoked.)
|
||
Complain about implicit character*(*).
|
||
|
||
Thu Nov 14 08:50:42 EST 1991:
|
||
libi77: change uint to Uint in fmt.h, rdfmt.c, wrtfmt.c; this change
|
||
should be invisible unless you're running a brain-damaged system.
|
||
|
||
Mon Nov 25 19:04:40 EST 1991:
|
||
libi77: correct botches introduced 17 Oct. 1991 and 14 Nov. 1991
|
||
(change uint to Uint in lwrite.c; other changes that only matter if
|
||
sizeof(int) != sizeof(long)).
|
||
Add a more meaningful error message when bailing out due to an attempt
|
||
to invoke a COMMON variable as a function.
|
||
|
||
Sun Dec 1 19:29:24 EST 1991:
|
||
libi77: uio.c: add test for read failure (seq. unformatted reads);
|
||
adjust an error return from EOF to off end of record.
|
||
|
||
Tue Dec 10 17:42:28 EST 1991:
|
||
Add tests to prevent memory faults with bad uses of character*(*).
|
||
|
||
Thu Dec 12 11:24:41 EST 1991:
|
||
libi77: fix bug with internal list input that caused the last
|
||
character of each record to be ignored; adjust error message in
|
||
internal formatted input from "end-of-file" to "off end of record"
|
||
if the format specifies more characters than the record contains.
|
||
|
||
Wed Dec 18 17:48:11 EST 1991:
|
||
Fix bug in translating nonsensical ichar invocations involving
|
||
concatenations.
|
||
Fix bug in passing intrinsics lle, llt, lge, lgt as arguments;
|
||
hl_le was being passed rather than l_le, etc.
|
||
libf77: adjust length parameters from long to ftnlen, for
|
||
compiling with f2c_i2 defined.
|
||
|
||
Sat Dec 21 15:30:57 EST 1991:
|
||
Allow DO nnn ... to end with an END DO statement labelled nnn.
|
||
|
||
Tue Dec 31 13:53:47 EST 1991:
|
||
Fix bug in handling dimension a(n**3,2) -- pow_ii was called
|
||
incorrectly.
|
||
Fix bug in translating
|
||
subroutine x(abc,n)
|
||
character abc(n)
|
||
write(abc,'(i10)') 123
|
||
end
|
||
(omitted declaration and initialiation of abc_dim1).
|
||
Complain about dimension expressions of such invalid types
|
||
as complex and logical.
|
||
|
||
Fri Jan 17 11:54:20 EST 1992:
|
||
Diagnose some illegal uses of main program name (rather than
|
||
memory faulting).
|
||
libi77: (1) In list and namelist input, treat "r* ," and "r*,"
|
||
alike (where r is a positive integer constant), and fix a bug in
|
||
handling null values following items with repeat counts (e.g.,
|
||
2*1,,3). (2) For namelist reading of a numeric array, allow a new
|
||
name-value subsequence to terminate the current one (as though the
|
||
current one ended with the right number of null values).
|
||
(3) [lio.h, lwrite.c]: omit insignificant zeros in list and namelist
|
||
output. (Compile with -DOld_list_output to get the old behavior.)
|
||
|
||
Sat Jan 18 15:58:01 EST 1992:
|
||
libi77: make list output consistent with F format by printing .1
|
||
rather than 0.1 (introduced yesterday).
|
||
|
||
Wed Jan 22 08:32:43 EST 1992:
|
||
libi77: add comment to README pointing out preconnection of
|
||
Fortran units 5, 6, 0 to stdin, stdout, stderr (respectively).
|
||
|
||
Mon Feb 3 11:57:53 EST 1992:
|
||
libi77: fix namelist read bug that caused the character following
|
||
a comma to be ignored.
|
||
|
||
Fri Feb 28 01:04:26 EST 1992:
|
||
libf77: fix buggy z_sqrt.c (double precision square root), which
|
||
misbehaved for arguments in the southwest quadrant.
|
||
|
||
Thu Mar 19 15:05:18 EST 1992:
|
||
Fix bug (introduced 17 Jan 1992) in handling multiple entry points
|
||
of differing types (with implicitly typed entries appearing after
|
||
the first executable statement).
|
||
Fix memory fault in the following illegal Fortran:
|
||
double precision foo(i)
|
||
* illegal: above should be "double precision function foo(i)"
|
||
foo = i * 3.2
|
||
entry moo(i)
|
||
end
|
||
Note about ANSI_Libraries (relevant, e.g., to IRIX 4.0.1 and AIX)
|
||
added to README.
|
||
Abort zero divides during constant simplification.
|
||
|
||
Sat Mar 21 01:27:09 EST 1992:
|
||
Tweak ckalloc (misc.c) for systems where malloc(0) = 0; this matters
|
||
for subroutines with multiple entry points but no arguments.
|
||
Add "struct memblock;" to init.c (irrelevant to most compilers).
|
||
|
||
Wed Mar 25 13:31:05 EST 1992:
|
||
Fix bug with IMPLICIT INTEGER*4(...): under -i2 or -I2, the *4 was
|
||
ignored.
|
||
|
||
Tue May 5 09:53:55 EDT 1992:
|
||
Tweaks to README; e.g., ANSI_LIbraries changed to ANSI_Libraries .
|
||
|
||
Wed May 6 23:49:07 EDT 1992
|
||
Under -A and -C++, have subroutines return 0 (even if they have
|
||
no * arguments).
|
||
Adjust libi77 (rsne.c and lread.c) for systems where ungetc is
|
||
a macro. Tweak lib[FI]77/makefile to use unique intermediate file
|
||
names (for parallel makes).
|
||
|
||
Tue May 19 09:03:05 EDT 1992:
|
||
Adjust libI77 to make err= work with internal list and formatted I/O.
|
||
|
||
Sat May 23 18:17:42 EDT 1992:
|
||
Under -A and -C++, supply "return 0;" after the code generated for
|
||
a STOP statement -- the C compiler doesn't know that s_stop won't
|
||
return.
|
||
New (mutually exclusive) options:
|
||
-f treats all input lines as free-format lines,
|
||
honoring text that appears after column 72
|
||
and not padding lines shorter than 72 characters
|
||
with blanks (which matters if a character string
|
||
is continued across 2 or more lines).
|
||
-72 treats text appearing after column 72 as an error.
|
||
|
||
Sun May 24 09:45:37 EDT 1992:
|
||
Tweak description of -f in f2c.1 and f2c.1t; update f2c.ps .
|
||
|
||
Fri May 29 01:17:15 EDT 1992:
|
||
Complain about externals used as variables. Example
|
||
subroutine foo(a,b)
|
||
external b
|
||
a = a*b ! illegal use of b; perhaps should be b()
|
||
end
|
||
|
||
Mon Jun 15 11:15:27 EDT 1992:
|
||
Fix bug in handling namelists with names that have underscores.
|
||
|
||
Sat Jun 27 17:30:59 EDT 1992:
|
||
Under -A and -C++, end Main program aliases with "return 0;".
|
||
Under -A and -C++, use .P files and usage in previous subprograms
|
||
in the current file to give prototypes for functions declared EXTERNAL
|
||
but not invoked.
|
||
Fix memory fault under -d1 -P .
|
||
Under -A and -C++, cast arguments to the right types in calling
|
||
a function that has been defined in the current file or in a .P file.
|
||
Fix bug in handling multi-dimensional arrays with array references
|
||
in their leading dimensions.
|
||
Fix bug in the intrinsic cmplx function when the first argument
|
||
involves an expression for which f2c generates temporary variables,
|
||
e.g. cmplx(abs(real(a)),1.) .
|
||
|
||
Sat Jul 18 07:36:58 EDT 1992:
|
||
Fix buglet with -e1c (invisible on most systems) temporary file
|
||
f2c_functions was unlinked before being closed.
|
||
libf77: fix bugs in evaluating m**n for integer n < 0 and m an
|
||
integer different from 1 or a real or double precision 0.
|
||
Catch SIGTRAP (to print "Trace trap" before aborting). Programs
|
||
that previously erroneously computed 1 for 0**-1 may now fault.
|
||
Relevant routines: main.c pow_di.c pow_hh.c pow_ii.c pow_ri.c .
|
||
|
||
Sat Jul 18 08:40:10 EDT 1992:
|
||
libi77: allow namelist input to end with & (e.g. &end).
|
||
|
||
Thu Jul 23 00:14:43 EDT 1992
|
||
Append two underscores rather than one to C keywords used as
|
||
local variables to avoid conflicts with similarly named COMMON blocks.
|
||
|
||
Thu Jul 23 11:20:55 EDT 1992:
|
||
libf77, libi77 updated to assume ANSI prototypes unless KR_headers
|
||
is #defined.
|
||
libi77 now recognizes a Z format item as in Fortran 90;
|
||
the implementation assumes 8-bit bytes and botches character strings
|
||
on little-endian machines (by printing their bytes from right to
|
||
left): expect this bug to persist; fixing it would require a
|
||
change to the I/O calling sequences.
|
||
|
||
Tue Jul 28 15:18:33 EDT 1992:
|
||
libi77: insert missed "#ifdef KR_headers" lines around getnum
|
||
header in rsne.c. Version not updated.
|
||
|
||
NOTE: "index from f2c" now ends with current timestamps of files in
|
||
"all from f2c/src", sorted by time. To bring your source up to date,
|
||
obtain source files with a timestamp later than the time shown in your
|
||
version.c.
|
||
|
||
Fri Aug 14 08:07:09 EDT 1992:
|
||
libi77: tweak wrt_E in wref.c to avoid signing NaNs.
|
||
|
||
Sun Aug 23 19:05:22 EDT 1992:
|
||
fc: supply : after O in getopt invocation (for -O1 -O2 -O3).
|
||
|
||
Mon Aug 24 18:37:59 EDT 1992:
|
||
Recant above tweak to fc: getopt is dumber than I thought;
|
||
it's necessary to say -O 1 (etc.).
|
||
libF77/README: add comments about ABORT, ERF, DERF, ERFC, DERFC,
|
||
GETARG, GETENV, IARGC, SIGNAL, and SYSTEM.
|
||
|
||
Tue Oct 27 01:57:42 EST 1992:
|
||
libf77, libi77:
|
||
1. Fix botched indirection in signal_.c.
|
||
2. Supply missing l_eof = 0 assignment to s_rsne() in rsne.c (so
|
||
end-of-file on other files won't confuse namelist reads of external
|
||
files).
|
||
3. Prepend f__ to external names that are only of internal
|
||
interest to lib[FI]77.
|
||
|
||
Thu Oct 29 12:37:18 EST 1992:
|
||
libf77: Fix botch in signal_.c when KR_headers is #defined;
|
||
add CFLAGS to makefile.
|
||
libi77: trivial change to makefile for consistency with
|
||
libF77/makefile.
|
||
|
||
Wed Feb 3 02:05:16 EST 1993:
|
||
Recognize types INTEGER*1, LOGICAL*1, LOGICAL*2, INTEGER*8.
|
||
INTEGER*8 is not well tested and will only work reasonably on
|
||
systems where int = 4 bytes, long = 8 bytes; on such systems,
|
||
you'll have to modify f2c.h appropriately, changing integer
|
||
from long to int and adding typedef long longint. You'll also
|
||
have to compile libI77 with Allow_TYQUAD #defined and adjust
|
||
libF77/makefile to compile pow_qq.c. In the f2c source, changes
|
||
for INTEGER*8 are delimited by #ifdef TYQUAD ... #endif. You
|
||
can omit the INTEGER*8 changes by compiling with NO_TYQUAD
|
||
#defined. Otherwise, the new command-line option -!i8
|
||
disables recognition of INTEGER*8.
|
||
libf77: add pow_qq.c
|
||
libi77: add #ifdef Allow_TYQUAD stuff. Changes for INTEGER*1,
|
||
LOGICAL*1, and LOGICAL*2 came last 23 July 1992. Fix bug in
|
||
backspace (that only bit when the last character of the second
|
||
or subsequent buffer read was the previous newline). Guard
|
||
against L_tmpnam being too small in endfile.c. For MSDOS,
|
||
close and reopen files when copying to truncate. Lengthen
|
||
LINTW (buffer size in lwrite.c).
|
||
Add \ to the end of #define lines that get broken.
|
||
Fix bug in handling NAMELIST of items in EQUIVALENCE.
|
||
Under -h (or -hd), convert Hollerith to integer in general expressions
|
||
(e.g., assignments), not just when they're passed as arguments, and
|
||
blank-pad rather than 0-pad the Hollerith to a multiple of
|
||
sizeof(integer) or sizeof(doublereal).
|
||
Add command-line option -s, which instructs f2c preserve multi-
|
||
dimensional subscripts (by emitting and using appropriate #defines).
|
||
Fix glitch (with default type inferences) in examples like
|
||
call foo('abc')
|
||
end
|
||
subroutine foo(goo)
|
||
end
|
||
This gave two warning messages:
|
||
Warning on line 4 of y.f: inconsistent calling sequences for foo:
|
||
here 1, previously 2 args and string lengths.
|
||
Warning on line 4 of y.f: inconsistent calling sequences for foo:
|
||
here 2, previously 1 args and string lengths.
|
||
Now the second Warning is suppressed.
|
||
Complain about all inconsistent arguments, not just the first.
|
||
Switch to automatic creation of "all from f2c/src". For folks
|
||
getting f2c source via ftp, this means f2c/src/all.Z is now an
|
||
empty file rather than a bundle.
|
||
Separate -P and -A: -P no longer implies -A.
|
||
|
||
Thu Feb 4 00:32:20 EST 1993:
|
||
Fix some glitches (introduced yesterday) with -h .
|
||
|
||
Fri Feb 5 01:40:38 EST 1993:
|
||
Fix bug in types conveyed for namelists (introduced 3 Feb. 1993).
|
||
|
||
Fri Feb 5 21:26:43 EST 1993:
|
||
libi77: tweaks to NAMELIST and open (after comments by Harold
|
||
Youngren):
|
||
1. Reading a ? instead of &name (the start of a namelist) causes
|
||
the namelist being sought to be written to stdout (unit 6);
|
||
to omit this feature, compile rsne.c with -DNo_Namelist_Questions.
|
||
2. Reading the wrong namelist name now leads to an error message
|
||
and an attempt to skip input until the right namelist name is found;
|
||
to omit this feature, compile rsne.c with -DNo_Bad_Namelist_Skip.
|
||
3. Namelist writes now insert newlines before each variable; to omit
|
||
this feature, compile xwsne.c with -DNo_Extra_Namelist_Newlines.
|
||
4. For OPEN of sequential files, ACCESS='APPEND' (or
|
||
access='anything else starting with "A" or "a"') causes the file to
|
||
be positioned at end-of-file, so a write will append to the file.
|
||
(This is nonstandard, but does not require modifying data
|
||
structures.)
|
||
|
||
Mon Feb 8 14:40:37 EST 1993:
|
||
Increase number of continuation lines allowed from 19 to 99,
|
||
and allow changing this limit with -NC (e.g. -NC200 for 200 lines).
|
||
Treat control-Z (at the beginning of a line) as end-of-file: see
|
||
the new penultimate paragraph of README.
|
||
Fix a rarely seen glitch that could make an error messages to say
|
||
"line 0".
|
||
|
||
Tue Feb 9 02:05:40 EST 1993
|
||
libi77: change some #ifdef MSDOS lines to #ifdef NON_UNIX_STDIO,
|
||
and, in err.c under NON_UNIX_STDIO, avoid close(creat(name,0666))
|
||
when the unit has another file descriptor for name.
|
||
|
||
Tue Feb 9 17:12:49 EST 1993
|
||
libi77: more tweaks for NON_UNIX_STDIO: use stdio routines
|
||
rather than open, close, creat, seek, fdopen (except for f__isdev).
|
||
|
||
Fri Feb 12 15:49:33 EST 1993
|
||
Update src/gram.c (which was forgotten in the recent updates).
|
||
Most folks regenerate it anyway (wity yacc or bison).
|
||
|
||
Thu Mar 4 17:07:38 EST 1993
|
||
Increase default max labels in computed gotos and alternate returns
|
||
to 257, and allow -Nl1234 to specify this number.
|
||
Tweak put.c to check p->tag == TADDR in realpart() and imagpart().
|
||
Adjust fc script to allow .r (RATFOR) files and -C (check subscripts).
|
||
Avoid declaring strchr in niceprintf.c under -DANSI_Libraries .
|
||
gram.c updated again.
|
||
libi77: err.c, open.c: take declaration of fdopen from rawio.h.
|
||
|
||
Sat Mar 6 07:09:11 EST 1993
|
||
libi77: uio.c: adjust off-end-of-record test for sequential
|
||
unformatted reads to respond to err= rather than end= .
|
||
|
||
Sat Mar 6 16:12:47 EST 1993
|
||
Treat scalar arguments of the form (v) and v+0, where v is a variable,
|
||
as expressions: assign to a temporary variable, and pass the latter.
|
||
gram.c updated.
|
||
|
||
Mon Mar 8 09:35:38 EST 1993
|
||
"f2c.h from f2c" updated to add types logical1 and integer1 for
|
||
LOGICAL*1 and INTEGER*1. ("f2c.h from f2c" is supposed to be the
|
||
same as "f2c.h from f2c/src", which was updated 3 Feb. 1993.)
|
||
|
||
Mon Mar 8 17:57:55 EST 1993
|
||
Fix rarely seen bug that could cause strange casts in function
|
||
invocations (revealed by an example with msdos/f2c.exe).
|
||
msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
|
||
|
||
Fri Mar 12 12:37:01 EST 1993
|
||
Fix bug with -s in handling subscripts involving min, max, and
|
||
complicated expressions requiring temporaries.
|
||
Fix bug in handling COMMONs that need padding by a char array.
|
||
msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
|
||
|
||
Fri Mar 12 17:16:16 EST 1993
|
||
libf77, libi77: updated for compiling under C++.
|
||
|
||
Mon Mar 15 16:21:37 EST 1993
|
||
libi77: more minor tweaks (for -DKR_headers); Version.c not changed.
|
||
|
||
Thu Mar 18 12:37:30 EST 1993
|
||
Flag -r (for discarding carriage-returns on systems that end lines
|
||
with carriage-return/newline pairs, e.g. PCs) added to xsum, and
|
||
xsum.c converted to ANSI/ISO syntax (with K&R syntax available with
|
||
-DKR_headers). [When time permits, the f2c source will undergo a
|
||
similar conversion.]
|
||
libi77: tweaks to #includes in endfile.c, err.c, open.c, rawio.h;
|
||
Version.c not changed.
|
||
f2c.ps updated (to pick up revision of 2 Feb. 1993 to f2c.1).
|
||
|
||
Fri Mar 19 09:19:26 EST 1993
|
||
libi77: add (char *) casts to malloc and realloc invocations
|
||
in err.c, open.c; Version.c not changed.
|
||
|
||
Tue Mar 30 07:17:15 EST 1993
|
||
Fix bug introduced 6 March 1993: possible memory corruption when
|
||
loops in data statements involve constant subscripts, as in
|
||
DATA (GUNIT(1,I),I=0,14)/15*-1/
|
||
|
||
Tue Mar 30 16:17:42 EST 1993
|
||
Fix bug with -s: (floating-point array item)*(complex item)
|
||
generates an _subscr() reference for the floating-point array,
|
||
but a #define for the _subscr() was omitted.
|
||
|
||
Tue Apr 6 12:11:22 EDT 1993
|
||
libi77: adjust error returns for formatted inputs to flush the current
|
||
input line when err= is specified. To restore the old behavior (input
|
||
left mid-line), either adjust the #definition of errfl in fio.h or omit
|
||
the invocation of f__doend in err__fl (in err.c).
|
||
|
||
Tue Apr 6 13:30:04 EDT 1993
|
||
Fix bug revealed in
|
||
subroutine foo(i)
|
||
call goo(int(i))
|
||
end
|
||
which now passes a copy of i, rather than i itself.
|
||
|
||
Sat Apr 17 11:41:02 EDT 1993
|
||
Adjust appending of underscores to conform with f2c.ps ("A Fortran
|
||
to C Converter"): names that conflict with C keywords or f2c type
|
||
names now have just one underscore appended (rather than two); add
|
||
"integer1", "logical1", "longint" to the keyword list.
|
||
Append underscores to names that appear in EQUIVALENCE and are
|
||
component names in a structure declared in f2c.h, thus avoiding a
|
||
problem caused by the #defines emitted for equivalences. Example:
|
||
complex a
|
||
equivalence (i,j)
|
||
a = 1 ! a.i went awry because of #define i
|
||
j = 2
|
||
write(*,*) a, i
|
||
end
|
||
Adjust line-breaking logic to avoid splitting very long constants
|
||
(and names). Example:
|
||
! The next line starts with tab and thus is a free-format line.
|
||
a=.012345689012345689012345689012345689012345689012345689012345689012345689
|
||
end
|
||
Omit extraneous "return 0;" from entry stubs emitted for multiple
|
||
entry points of type character, complex, or double complex.
|
||
|
||
Sat Apr 17 14:35:05 EDT 1993
|
||
Fix bug (introduced 4 Feb.) in separating -P from -A that kept f2c
|
||
from re-reading a .P file written without -A or -C++ describing a
|
||
routine with an external argument. [See the just-added note about
|
||
separating -P from -A in the changes above for 3 Feb. 1993.]
|
||
Fix bug (type UNKNOWN for V in the example below) revealed by
|
||
subroutine a()
|
||
external c
|
||
call b(c)
|
||
end
|
||
subroutine b(v)
|
||
end
|
||
|
||
Sun Apr 18 19:55:26 EDT 1993
|
||
Fix wrong calling sequence for mem() in yesterday's addition to
|
||
equiv.c .
|
||
|
||
Wed Apr 21 17:39:46 EDT 1993
|
||
Fix bug revealed in
|
||
|
||
ASSIGN 10 TO L1
|
||
GO TO 20
|
||
10 ASSIGN 30 TO L2
|
||
STOP 10
|
||
|
||
20 ASSIGN 10 TO L2 ! Bug here because 10 had been assigned
|
||
! to another label, then defined.
|
||
GO TO L2
|
||
30 END
|
||
|
||
Fri Apr 23 18:38:50 EDT 1993
|
||
Fix bug with -h revealed in
|
||
CHARACTER*9 FOO
|
||
WRITE(FOO,'(I6)') 1
|
||
WRITE(FOO,'(I6)') 2 ! struct icilist io___3 botched
|
||
END
|
||
|
||
Tue Apr 27 16:08:28 EDT 1993
|
||
Tweak to makefile: remove "size f2c".
|
||
|
||
Tue May 4 23:48:20 EDT 1993
|
||
libf77: tweak signal_ line of f2ch.add .
|
||
|
||
Tue Jun 1 13:47:13 EDT 1993
|
||
Fix bug introduced 3 Feb. 1993 in handling multiple entry
|
||
points with differing return types -- the postfix array in proc.c
|
||
needed a new entry for integer*8 (which resulted in wrong
|
||
Multitype suffixes for non-integral types).
|
||
For (default) K&R C, generate VOID rather than int functions for
|
||
functions of Fortran type character, complex, and double complex.
|
||
msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
|
||
|
||
Tue Jun 1 23:11:15 EDT 1993
|
||
f2c.h: add Multitype component g and commented type longint.
|
||
proc.c: omit "return 0;" from stubs for complex and double complex
|
||
entries (when entries have multiple types); add test to avoid memory
|
||
fault with illegal combinations of entry types.
|
||
|
||
Mon Jun 7 12:00:47 EDT 1993
|
||
Fix memory fault in
|
||
common /c/ m
|
||
integer m(1)
|
||
data m(1)/1/, m(2)/2/ ! one too many initializers
|
||
end
|
||
msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
|
||
|
||
Fri Jun 18 13:55:51 EDT 1993
|
||
libi77: change type of signal_ in f2ch.add; change type of il in
|
||
union Uint from long to integer (for machines like the DEC Alpha,
|
||
where integer should be the same as int). Version.c not changed.
|
||
Tweak gram.dcl and gram.head: add semicolons after some rules that
|
||
lacked them, and remove an extraneous semicolon. These changes are
|
||
completely transparent to our local yacc programs, but apparently
|
||
matter on some VMS systems.
|
||
|
||
Wed Jun 23 01:02:56 EDT 1993
|
||
Update "fc" shell script, and bring f2c.1 and f2c.1t up to date:
|
||
they're meant to be linked with (i.e., the same as) src/f2c.1 and
|
||
src/f2c.1t . [In the last update of f2c.1* (2 Feb. 1993), only
|
||
src/f2c.1 and src/f2c.1t got changed -- a mistake.]

|
||
libi77: fix bug in format reversions for internal writes.
|
||
Example:
|
||
character*60 lines(2)
|
||
write(lines,"('n =',i3,2(' more text',i3))") 3, 4, 5, 6
|
||
write(*,*) 'lines(1) = ', lines(1)
|
||
write(*,*) 'lines(2) = ', lines(2)
|
||
end
|
||
gave an error message that began "iio: off end of record", rather
|
||
than giving the correct output:
|
||
|
||
lines(1) = n = 3 more text 4 more text 5
|
||
lines(2) = more text 6 more text
|
||
|
||
Thu Aug 5 11:31:14 EDT 1993
|
||
libi77: lread.c: fix bug in handling repetition counts for logical
|
||
data (during list or namelist input). Change struct f__syl to
|
||
struct syl (for buggy compilers).
|
||
|
||
Sat Aug 7 16:05:30 EDT 1993
|
||
libi77: lread.c (again): fix bug in namelist reading of incomplete
|
||
logical arrays.
|
||
Fix minor calling-sequence errors in format.c, output.c, putpcc.c:
|
||
should be invisible.
|
||
|
||
Mon Aug 9 09:12:38 EDT 1993
|
||
Fix erroneous cast under -A in translating
|
||
character*(*) function getc()
|
||
getc(2:3)=' ' !wrong cast in first arg to s_copy
|
||
end
|
||
libi77: lread.c: fix bug in namelist reading of an incomplete array
|
||
of numeric data followed by another namelist item whose name starts
|
||
with 'd', 'D', 'e', or 'E'.
|
||
|
||
Fri Aug 20 13:22:10 EDT 1993
|
||
Fix bug in do while revealed by
|
||
subroutine skdig (line, i)
|
||
character line*(*), ch*1
|
||
integer i
|
||
logical isdigit
|
||
isdigit(ch) = ch.ge.'0' .and. ch.le.'9'
|
||
do while (isdigit(line(i:i))) ! ch__1[0] was set before
|
||
! "while(...) {...}"
|
||
i = i + 1
|
||
enddo
|
||
end
|
||
|
||
Fri Aug 27 08:22:54 EDT 1993
|
||
Add #ifdefs to avoid declaring atol when it is a macro; version.c
|
||
not updated.
|
||
|
||
Wed Sep 8 12:24:26 EDT 1993
|
||
libi77: open.c: protect #include "sys/..." with
|
||
#ifndef NON_UNIX_STDIO; Version date not changed.
|
||
|
||
Thu Sep 9 08:51:21 EDT 1993
|
||
Adjust "include" to interpret file names relative to the directory
|
||
of the file that contains the "include".
|
||
|
||
Fri Sep 24 00:56:12 EDT 1993
|
||
Fix offset error resulting from repeating the same equivalence
|
||
statement twice. Example:
|
||
real a(2), b(2)
|
||
equivalence (a(2), b(2))
|
||
equivalence (a(2), b(2))
|
||
end
|
||
Increase MAXTOKENLEN (to roughly the largest allowed by ANSI C).
|
||
|
||
Mon Sep 27 08:55:09 EDT 1993
|
||
libi77: endfile.c: protect #include "sys/types.h" with
|
||
#ifndef NON_UNIX_STDIO; Version.c not changed.
|
||
|
||
Fri Oct 15 15:37:26 EDT 1993
|
||
Fix rarely seen parsing bug illustrated by
|
||
subroutine foo(xabcdefghij)
|
||
character*(*) xabcdefghij
|
||
IF (xabcdefghij.NE.'##') GOTO 40
|
||
40 end
|
||
in which the spacing in the IF line is crucial.
|
||
|
||
Thu Oct 21 13:55:11 EDT 1993
|
||
Give more meaningful error message (then "unexpected character in
|
||
cds") when constant simplification leads to Infinity or NaN.
|
||
|
||
Wed Nov 10 15:01:05 EST 1993
|
||
libi77: backspace.c: adjust, under -DMSDOS, to cope with MSDOS
|
||
text files, as handled by some popular PC C compilers. Beware:
|
||
the (defective) libraries associated with these compilers assume lines
|
||
end with \r\n (conventional MS-DOS text files) -- and ftell (and
|
||
hence the current implementation of backspace) screws up if lines with
|
||
just \n.
|
||
|
||
Thu Nov 18 09:37:47 EST 1993
|
||
Give a better error (than "control stack empty") for an extraneous
|
||
ENDDO. Example:
|
||
enddo
|
||
end
|
||
Update comments about ftp in "readme from f2c".
|
||
|
||
Sun Nov 28 17:26:50 EST 1993
|
||
Change format of time stamp in version.c to yyyymmdd.
|
||
Sort parameter adjustments (or complain of impossible dependencies)
|
||
so that dummy arguments are referenced only after being adjusted.
|
||
Example:
|
||
subroutine foo(a,b)
|
||
integer a(2) ! a must be adjusted before b
|
||
double precision b(a(1),a(2))
|
||
call goo(b(3,4))
|
||
end
|
||
Adjust structs for initialized common blocks and equivalence classes
|
||
to omit the trailing struct component added to force alignment when
|
||
padding already forces the desired alignment. Example:
|
||
PROGRAM TEST
|
||
COMMON /Z/ A, CC
|
||
CHARACTER*4 CC
|
||
DATA cc /'a'/
|
||
END
|
||
now gives
|
||
struct {
|
||
integer fill_1[1];
|
||
char e_2[4];
|
||
} z_ = { {0}, {'a', ' ', ' ', ' '} };
|
||
rather than
|
||
struct {
|
||
integer fill_1[1];
|
||
char e_2[4];
|
||
real e_3;
|
||
} z_ = { {0}, {'a', ' ', ' ', ' '}, (float)0. };
|
||
|
||
Wed Dec 8 16:24:43 EST 1993
|
||
Adjust lex.c to recognize # nnn "filename" lines emitted by cpp;
|
||
this affects the file names and line numbers in error messages and
|
||
the #line lines emitted under -g.
|
||
Under -g, arrange for a file that starts with an executable
|
||
statement to have the first #line line indicate line 1, rather
|
||
than the line number of the END statement ending the main program.
|
||
Adjust fc script to run files ending in .F through /lib/cpp.
|
||
Fix bug ("Impossible tag 2") in
|
||
if (t .eq. (0,2)) write(*,*) 'Bug!'
|
||
end
|
||
libi77: iio.c: adjust internal formatted reads to treat short records
|
||
as though padded with blanks (rather than causing an "off end of record"
|
||
error).
|
||
|
||
Wed Dec 15 15:19:15 EST 1993
|
||
fc: adjusted for .F files to pass -D and -I options to cpp.
|
||
|
||
Fri Dec 17 20:03:38 EST 1993
|
||
Fix botch introduced 28 Nov. 1993 in vax.c; change "version of"
|
||
to "version".
|
||
|
||
Tue Jan 4 15:39:52 EST 1994
|
||
msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only).
|
||
|
||
Wed Jan 19 08:55:19 EST 1994
|
||
Arrange to accept
|
||
integer Nx, Ny, Nz
|
||
parameter (Nx = 10, Ny = 20)
|
||
parameter (Nz = max(Nx, Ny))
|
||
integer c(Nz)
|
||
call foo(c)
|
||
end
|
||
rather than complaining "Declaration error for c: adjustable dimension
|
||
on non-argument". The necessary changes cause some hitherto unfolded
|
||
constant expressions to be folded.
|
||
Accept BYTE as a synonym for INTEGER*1.
|
||
|
||
Thu Jan 27 08:57:40 EST 1994
|
||
Fix botch in changes of 19 Jan. 1994 that broke entry points with
|
||
multi-dimensional array arguments that did not appear in the subprogram
|
||
argument list and whose leading dimensions depend on arguments.
|
||
|
||
Mon Feb 7 09:24:30 EST 1994
|
||
Remove artifact in "fc" script that caused -O to be ignored:
|
||
87c87
|
||
< # lcc ignores -O...
|
||
---
|
||
> CFLAGS="$CFLAGS $O"
|
||
|
||
Sun Feb 20 17:04:58 EST 1994
|
||
Fix bugs reading .P files for routines with arguments of type
|
||
INTEGER*1, INTEGER*8, LOGICAL*2.
|
||
Fix glitch in reporting inconsistent arguments for routines involving
|
||
character arguments: "arg n" had n too large by the number of
|
||
character arguments.
|
||
|
||
Tue Feb 22 20:50:08 EST 1994
|
||
Trivial changes to data.c format.c main.c niceprintf.c output.h and
|
||
sysdep.h (consistency improvements).
|
||
libI77: lread.c: check for NULL return from realloc.
|
||
|
||
Fri Feb 25 23:56:08 EST 1994
|
||
output.c, sysdep.h: arrange for -DUSE_DTOA to use dtoa.c and g_fmt.c
|
||
for correctly rounded decimal values on IEEE-arithmetic machines
|
||
(plus machines with VAX and IBM-mainframe arithmetic). These
|
||
routines are available from netlib's fp directory.
|
||
msdos/f2cx.exe.Z and msdos/f2c.exe.Z updated (ftp access only); the
|
||
former uses -DUSE_DTOA to keep 12 from printing as 12.000000000000001.
|
||
vax.c: fix wrong arguments to badtag and frchain introduced
|
||
28 Nov. 1993.
|
||
Source for f2c converted to ANSI/ISO format, with the K&R format
|
||
available by compilation with -DKR_headers .
|
||
Arrange for (double precision expression) relop (single precision
|
||
constant) to retain the single-precision nature of the constant.
|
||
Example:
|
||
double precision t
|
||
if (t .eq. 0.3) ...
|
||
|
||
Mon Feb 28 11:40:24 EST 1994
|
||
README updated to reflect a modification just made to netlib's
|
||
"dtoa.c from fp":
|
||
96a97,105
|
||
> Also add the rule
|
||
>
|
||
> dtoa.o: dtoa.c
|
||
> $(CC) -c $(CFLAGS) -DMALLOC=ckalloc -DIEEE... dtoa.c
|
||
>
|
||
> (without the initial tab) to the makefile, where IEEE... is one of
|
||
> IEEE_MC68k, IEEE_8087, VAX, or IBM, depending on your machine's
|
||
> arithmetic. See the comments near the start of dtoa.c.

|
||
|
||
Sat Mar 5 09:41:52 EST 1994
|
||
Complain about functions with the name of a previously declared
|
||
common block (which is illegal).
|
||
New option -d specifies the directory for output .c and .P files;
|
||
f2c.1 and f2c.1t updated. The former undocumented debug option -dnnn
|
||
is now -Dnnn.
|
||
|
||
Thu Mar 10 10:21:44 EST 1994
|
||
libf77: add #undef min and #undef max lines to s_paus.c s_stop.c
|
||
and system_.c; Version.c not changed.
|
||
libi77: add -DPad_UDread lines to uio.c and explanation to README:
|
||
Some buggy Fortran programs use unformatted direct I/O to write
|
||
an incomplete record and later read more from that record than
|
||
they have written. For records other than the last, the unwritten
|
||
portion of the record reads as binary zeros. The last record is
|
||
a special case: attempting to read more from it than was written
|
||
gives end-of-file -- which may help one find a bug. Some other
|
||
Fortran I/O libraries treat the last record no differently than
|
||
others and thus give no help in finding the bug of reading more
|
||
than was written. If you wish to have this behavior, compile
|
||
uio.c with -DPad_UDread .
|
||
Version.c not changed.
|
||
|
||
Tue Mar 29 17:27:54 EST 1994
|
||
Adjust make_param so dimensions involving min, max, and other
|
||
complicated constant expressions do not provoke error messages
|
||
about adjustable dimensions on non-arguments.
|
||
Fix botch introduced 19 Jan 1994: "adjustable dimension on non-
|
||
argument" messages could cause some things to be freed twice.
|
||
|
||
Tue May 10 07:55:12 EDT 1994
|
||
Trivial changes to exec.c, p1output.c, parse_args.c, proc.c,
|
||
and putpcc.c: change arguments from
|
||
type foo[]
|
||
to
|
||
type *foo
|
||
for consistency with defs.h. For most compilers, this makes no
|
||
difference.
|
||
|
||
Thu Jun 2 12:18:18 EDT 1994
|
||
Fix bug in handling FORMAT statements that have adjacent character
|
||
(or Hollerith) strings: an extraneous \002 appeared between the
|
||
strings.
|
||
libf77: under -DNO_ONEXIT, arrange for f_exit to be called just
|
||
once; previously, upon abnormal termination (including stop statements),
|
||
it was called twice.
|
||
|
||
Mon Jun 6 15:52:57 EDT 1994
|
||
libf77: Avoid references to SIGABRT and SIGIOT if neither is defined;
|
||
Version.c not changed.
|
||
libi77: Add cast to definition of errfl() in fio.h; this only matters
|
||
on systems with sizeof(int) < sizeof(long). Under -DNON_UNIX_STDIO,
|
||
use binary mode for direct formatted files (to avoid any confusion
|
||
connected with \n characters).
|
||
|
||
Fri Jun 10 16:47:31 EDT 1994
|
||
Fix bug under -A in handling unreferenced (and undeclared)
|
||
external arguments in subroutines with multiple entry points. Example:
|
||
subroutine m(fcn,futil)
|
||
external fcn,futil
|
||
call fcn
|
||
entry mintio(i1) ! (D_fp)0 rather than (U_fp)0 for futil
|
||
end
|
||
|
||
Wed Jun 15 10:38:14 EDT 1994
|
||
Allow char(constant expression) function in parameter declarations.
|
||
(This was probably broken in the changes of 29 March 1994.)
|
||
|
||
Fri Jul 1 23:54:00 EDT 1994
|
||
Minor adjustments to makefile (rule for f2c.1 commented out) and
|
||
sysdep.h (#undef KR_headers if __STDC__ is #defined, and base test
|
||
for ANSI_Libraries and ANSI_Prototypes on KR_headers rather than
|
||
__STDC__); version.c touched but not changed.
|
||
libi77: adjust fp.h so local.h is only needed under -DV10;
|
||
Version.c not changed.
|
||
|
||
Tue Jul 5 03:05:46 EDT 1994
|
||
Fix segmentation fault in
|
||
subroutine foo(a,b,k)
|
||
data i/1/
|
||
double precision a(k,1) ! sequence error: must precede data
|
||
b = a(i,1)
|
||
end
|
||
libi77: Fix bug (introduced 6 June 1994?) in reopening files under
|
||
NON_UNIX_STDIO.
|
||
Fix some error messages caused by illegal Fortran. Examples:
|
||
* 1.
|
||
x(i) = 0 !Missing declaration for array x
|
||
call f(x) !Said Impossible storage class 8 in routine mkaddr
|
||
end !Now says invalid use of statement function x
|
||
* 2.
|
||
f = g !No declaration for g; by default it's a real variable
|
||
call g !Said invalid class code 2 for function g
|
||
end !Now says g cannot be called
|
||
* 3.
|
||
intrinsic foo !Invalid intrinsic name
|
||
a = foo(b) !Said intrcall: bad intrgroup 0
|
||
end !Now just complains about line 1
|
||
|
||
Tue Jul 5 11:14:26 EDT 1994
|
||
Fix glitch in handling erroneous statement function declarations.
|
||
Example:
|
||
a(j(i) - i) = a(j(i) - i) + 1 ! bad statement function
|
||
call foo(a(3)) ! Said Impossible type 0 in routine mktmpn
|
||
end ! Now warns that i and j are not used
|
||
|
||
Wed Jul 6 17:31:25 EDT 1994
|
||
Tweak test for statement functions that (illegally) call themselves;
|
||
f2c will now proceed to check for other errors, rather than bailing
|
||
out at the first recursive statement function reference.
|
||
Warn about but retain divisions by 0 (instead of calling them
|
||
"compiler errors" and quiting). On IEEE machines, this permits
|
||
double precision nan, ninf, pinf
|
||
nan = 0.d0/0.d0
|
||
pinf = 1.d0/0.d0
|
||
ninf = -1.d0/0.d0
|
||
write(*,*) 'nan, pinf, ninf = ', nan, pinf, ninf
|
||
end
|
||
to print
|
||
nan, pinf, ninf = NaN Infinity -Infinity
|
||
libi77: wref.c: protect with #ifdef GOOD_SPRINTF_EXPONENT an
|
||
optimization that requires exponents to have 2 digits when 2 digits
|
||
suffice. lwrite.c wsfe.c (list and formatted external output):
|
||
omit ' ' carriage-control when compiled with -DOMIT_BLANK_CC .
|
||
Off-by-one bug fixed in character count for list output of character
|
||
strings. Omit '.' in list-directed printing of Nan, Infinity.
|
||
|
||
Mon Jul 11 13:05:33 EDT 1994
|
||
src/gram.c updated.
|
||
|
||
Tue Jul 12 10:24:42 EDT 1994
|
||
libi77: wrtfmt.c: under G11.4, write 0. as " .0000 " rather
|
||
than " .0000E+00".
|
||
|
||
Thu Jul 14 17:55:46 EDT 1994
|
||
Fix glitch in changes of 6 July 1994 that could cause erroneous
|
||
"division by zero" warnings (or worse). Example:
|
||
subroutine foo(a,b)
|
||
y = b
|
||
a = a / y ! erroneous warning of division by zero
|
||
end
|
||
|
||
Mon Aug 1 16:45:17 EDT 1994
|
||
libi77: lread.c rsne.c: for benefit of systems with a buggy stdio.h,
|
||
declare ungetc when neither KR_headers nor ungetc is #defined.
|
||
Version.c not changed.
|
||
|
||
Wed Aug 3 01:53:00 EDT 1994
|
||
libi77: lwrite.c (list output): do not insert a newline when
|
||
appending an oversize item to an empty line.
|
||
|
||
Mon Aug 8 00:51:01 EDT 1994
|
||
Fix bug (introduced 3 Feb. 1993) that, under -i2, kept LOGICAL*2
|
||
variables from appearing in INQUIRE statements. Under -I2, allow
|
||
LOGICAL*4 variables to appear in INQUIRE. Fix intrinsic function
|
||
LEN so it returns a short value under -i2, a long value otherwise.
|
||
exec.c: fix obscure memory fault possible with bizarre (and highly
|
||
erroneous) DO-loop syntax.
|
||
|
||
Fri Aug 12 10:45:57 EDT 1994
|
||
libi77: fix glitch that kept ERR= (in list- or format-directed input)
|
||
from working after a NAMELIST READ.
|
||
|
||
Thu Aug 25 13:58:26 EDT 1994
|
||
Suppress -s when -C is specified.
|
||
Give full pathname (netlib@research.att.com) for netlib in readme and
|
||
src/README.
|
||
|
||
Wed Sep 7 22:13:20 EDT 1994
|
||
libi77: typesize.c: adjust to allow types LOGICAL*1, LOGICAL*2,
|
||
INTEGER*1, and (under -DAllow_TYQUAD) INTEGER*8 in NAMELISTs.
|
||
|
||
Fri Sep 16 17:50:18 EDT 1994
|
||
Change name adjustment for reserved words: instead of just appending
|
||
"_" (a single underscore), append "_a_" to local variable names to avoid
|
||
trouble when a common block is named a reserved word and the same
|
||
reserved word is also a local variable name. Example:
|
||
common /const/ a,b,c
|
||
real const(3)
|
||
equivalence (const(1),a)
|
||
a = 1.234
|
||
end
|
||
Arrange for ichar() to treat characters as unsigned.
|
||
libf77: s_cmp.c: treat characters as unsigned in comparisons.
|
||
These changes for unsignedness only matter for strings that contain
|
||
non-ASCII characters. Now ichar() should always be >= 0.
|
||
|
||
Sat Sep 17 11:19:32 EDT 1994
|
||
fc: set rc=$? before exit (to get exit code right in trap code).
|
||
|
||
Mon Sep 19 17:49:43 EDT 1994
|
||
libf77: s_paus.c: flush stderr after PAUSE; add #ifdef MSDOS stuff.
|
||
libi77: README: point out general need for -DMSDOS under MS-DOS.
|
||
|
||
Tue Sep 20 11:42:30 EDT 1994
|
||
Fix bug in comparing identically named common blocks, in which
|
||
all components have the same names and types, but at least one is
|
||
dimensioned (1) and the other is not dimensioned. Example:
|
||
subroutine foo
|
||
common /ab/ a
|
||
a=1. !!! translated correctly to ab_1.a = (float)1.;
|
||
end
|
||
subroutine goo
|
||
common /ab/ a(1)
|
||
a(1)=2. !!! translated erroneously to ab_1.a[0] = (float)2.
|
||
end
|
||
|
||
Tue Sep 27 23:47:34 EDT 1994
|
||
Fix bug introduced 16 Sept. 1994: don't add _a_ to C keywords
|
||
used as external names. In fact, return to earlier behavior of
|
||
appending __ to C keywords unless they are used as external names,
|
||
in which case they get just one underscore appended.
|
||
Adjust constant handling so integer and logical PARAMETERs retain
|
||
type information, particularly under -I2. Example:
|
||
SUBROUTINE FOO
|
||
INTEGER I
|
||
INTEGER*1 I1
|
||
INTEGER*2 I2
|
||
INTEGER*4 I4
|
||
LOGICAL L
|
||
LOGICAL*1 L1
|
||
LOGICAL*2 L2
|
||
LOGICAL*4 L4
|
||
PARAMETER (L=.FALSE., L1=.FALSE., L2=.FALSE., L4=.FALSE.)
|
||
PARAMETER (I=0,I1=0,I2=0,I4=0)
|
||
CALL DUMMY(I, I1, I2, I4, L, L1, L2, L4)
|
||
END
|
||
f2c.1t: Change f\^2c to f2c (omit half-narrow space) in line following
|
||
".SH NAME" for benefit of systems that cannot cope with troff commands
|
||
in this context.
|
||
|
||
Wed Sep 28 12:45:19 EDT 1994
|
||
libf77: s_cmp.c fix glitch in -DKR_headers version introduced
|
||
12 days ago.
|
||
|
||
Thu Oct 6 09:46:53 EDT 1994
|
||
libi77: util.c: omit f__mvgbt (which is never used).
|
||
f2c.h: change "long" to "long int" to facilitate the adjustments
|
||
by means of sed described above. Comment out unused typedef of Long.
|
||
|
||
Fri Oct 21 18:02:24 EDT 1994
|
||
libf77: add s_catow.c and adjust README to point out that changing
|
||
"s_cat.o" to "s_catow.o" in the makefile will permit the target of a
|
||
concatenation to appear on its right-hand side (contrary to the
|
||
Fortran 77 Standard and at the cost of some run-time efficiency).
|
||
|
||
Wed Nov 2 00:03:58 EST 1994
|
||
Adjust -g output to contain only one #line line per statement,
|
||
inserting \ before the \n ending lines broken because of their
|
||
length [this insertion was recanted 10 Dec. 1994]. This change
|
||
accommodates an idiocy in the ANSI/ISO C standard, which leaves
|
||
undefined the behavior of #line lines that occur within the arguments
|
||
to a macro call.
|
||
|
||
Wed Nov 2 14:44:27 EST 1994
|
||
libi77: under compilation with -DALWAYS_FLUSH, flush buffers at
|
||
the end of each write statement, and test (via the return from
|
||
fflush) for write failures, which can be caught with an ERR=
|
||
specifier in the write statement. This extra flushing slows
|
||
execution, but can abort execution or alter the flow of control
|
||
when a disk fills up.
|
||
f2c/src/io.c: Add ERR= test to e_wsle invocation (end of
|
||
list-directed external output) to catch write failures when libI77
|
||
is compiled with -DALWAYS_FLUSH.
|
||
|
||
Thu Nov 3 10:59:13 EST 1994
|
||
Fix bug in handling dimensions involving certain intrinsic
|
||
functions of constant expressions: the expressions, rather than
|
||
pointers to them, were passed. Example:
|
||
subroutine subtest(n,x)
|
||
real x(2**n,n) ! pow_ii(2,n) was called; now it's pow_ii(&c__2,n)
|
||
x(2,2)=3.
|
||
end
|
||
|
||
Tue Nov 8 23:56:30 EST 1994
|
||
malloc.c: remove assumption that only malloc calls sbrk. This
|
||
appears to make malloc.c useful on RS6000 systems.
|
||
|
||
Sun Nov 13 13:09:38 EST 1994
|
||
Turn off constant folding of integers used in floating-point
|
||
expressions, so the assignment in
|
||
subroutine foo(x)
|
||
double precision x
|
||
x = x*1000000*500000
|
||
end
|
||
is rendered as
|
||
*x = *x * 1000000 * 500000;
|
||
rather than as
|
||
*x *= 1783793664;
|
||
|
||
Sat Dec 10 16:31:40 EST 1994
|
||
Supply a better error message (than "Impossible type 14") for
|
||
subroutine foo
|
||
foo = 3
|
||
end
|
||
Under -g, convey name of included files to #line lines.
|
||
Recant insertion of \ introduced (under -g) 2 Nov. 1994.
|
||
|
||
Thu Dec 15 14:33:55 EST 1994
|
||
New command-line option -Idir specifies directories in which to
|
||
look for non-absolute include files (after looking in the directory
|
||
of the current input file). There can be several -Idir options, each
|
||
specifying one directory. All -Idir options are considered, from
|
||
left to right, until a suitably named file is found. The -I2 and -I4
|
||
command-line options have precedence, so directories named 2 or 4
|
||
must be spelled by some circumlocation, such as -I./2 .
|
||
f2c.ps updated to mention the new -Idir option, correct a typo,
|
||
and bring the man page at the end up to date.
|
||
lex.c: fix bug in reading line numbers in #line lines.
|
||
fc updated to pass -Idir options to f2c.
|
||
|
||
Thu Dec 29 09:48:03 EST 1994
|
||
Fix bug (e.g., addressing fault) in diagnosing inconsistency in
|
||
the type of function eta in the following example:
|
||
function foo(c1,c2)
|
||
double complex foo,c1,c2
|
||
double precision eta
|
||
foo = eta(c1,c2)
|
||
end
|
||
function eta(c1,c2)
|
||
double complex eta,c1,c2
|
||
eta = c1*c2
|
||
end
|
||
|
||
Mon Jan 2 13:27:26 EST 1995
|
||
Retain casts for SNGL (or FLOAT) that were erroneously optimized
|
||
away. Example:
|
||
subroutine foo(a,b)
|
||
double precision a,b
|
||
a = float(b) ! now rendered as *a = (real) (*b);
|
||
end
|
||
Use float (rather than double) temporaries in certain expressions
|
||
of type complex. Example: the temporary for sngl(b) in
|
||
complex a
|
||
double precision b
|
||
a = sngl(b) - (3.,4.)
|
||
is now of type float.
|
||
|
||
Fri Jan 6 00:00:27 EST 1995
|
||
Adjust intrinsic function cmplx to act as dcmplx (returning
|
||
double complex rather than complex) if either of its args is of
|
||
type double precision. The double temporaries used prior to 2 Jan.
|
||
1995 previously gave it this same behavior.
|
||
|
||
Thu Jan 12 12:31:35 EST 1995
|
||
Adjust -krd to use double temporaries in some calculations of
|
||
type complex.
|
||
libf77: pow_[dhiqrz][hiq].c: adjust x**i to work on machines
|
||
that sign-extend right shifts when i is the most negative integer.
|
||
|
||
Wed Jan 25 00:14:42 EST 1995
|
||
Fix memory fault in handling overlapping initializations in
|
||
block data
|
||
common /zot/ d
|
||
double precision d(3)
|
||
character*6 v(4)
|
||
real r(2)
|
||
equivalence (d(3),r(1)), (d(1),v(1))
|
||
data v/'abcdef', 'ghijkl', 'mnopqr', 'stuvwx'/
|
||
data r/4.,5./
|
||
end
|
||
names.c: add "far", "huge", "near" to c_keywords (causing them
|
||
to have __ appended when used as local variables).
|
||
libf77: add s_copyow.c, an alternative to s_copy.c for handling
|
||
(illegal) character assignments where the right- and left-hand
|
||
sides overlap, as in a(2:4) = a(1:3).
|
||
|
||
Thu Jan 26 14:21:19 EST 1995
|
||
libf77: roll s_catow.c and s_copyow.c into s_cat.c and s_copy.c,
|
||
respectively, allowing the left-hand side of a character assignment
|
||
to appear on its right-hand side unless s_cat.c and s_copy.c are
|
||
compiled with -DNO_OVERWRITE (which is a bit more efficient).
|
||
Fortran 77 forbids the left-hand side from participating in the
|
||
right-hand side (of a character assignment), but Fortran 90 allows it.
|
||
libi77: wref.c: fix glitch in printing the exponent of 0 when
|
||
GOOD_SPRINTF_EXPONENT is not #defined.
|
||
|
||
Fri Jan 27 12:25:41 EST 1995
|
||
Under -C++ -ec (or -C++ -e1c), surround struct declarations with
|
||
#ifdef __cplusplus
|
||
extern "C" {
|
||
#endif
|
||
and
|
||
#ifdef __cplusplus
|
||
}
|
||
#endif
|
||
(This isn't needed with cfront, but apparently is necessary with
|
||
some other C++ compilers.)
|
||
libf77: minor tweak to s_copy.c: copy forward whenever possible
|
||
(for better cache behavior).
|
||
|
||
Wed Feb 1 10:26:12 EST 1995
|
||
Complain about parameter statements that assign values to dummy
|
||
arguments, as in
|
||
subroutine foo(x)
|
||
parameter(x = 3.4)
|
||
end
|
||
|
||
Sat Feb 4 20:22:02 EST 1995
|
||
fc: omit "lib=/lib/num/lib.lo".
|
||
|
||
Wed Feb 8 08:41:14 EST 1995
|
||
Minor changes to exec.c, putpcc.c to avoid "bad tag" or "error
|
||
in frexpr" with certain invalid Fortran.
|
||
|
||
Sat Feb 11 08:57:39 EST 1995
|
||
Complain about integer overflows, both in simplifying integer
|
||
expressions, and in converting integers from decimal to binary.
|
||
Fix a memory fault in putcx1() associated with invalid input.
|
||
|
||
Thu Feb 23 11:20:59 EST 1995
|
||
Omit MAXTOKENLEN; realloc token if necessary (to handle very long
|
||
strings).
|
||
|
||
Fri Feb 24 11:02:00 EST 1995
|
||
libi77: iio.c: z_getc: insert (unsigned char *) to allow internal
|
||
reading of characters with high-bit set (on machines that sign-extend
|
||
characters).
|
||
|
||
Tue Mar 14 18:22:42 EST 1995
|
||
Fix glitch (in io.c) in handling 0-length strings in format
|
||
statements, as in
|
||
write(*,10)
|
||
10 format(' ab','','cd')
|
||
libi77: lread.c and rsfe.c: adjust s_rsle and s_rsfe to check for
|
||
end-of-file (to prevent infinite loops with empty read statements).
|
||
|
||
Wed Mar 22 10:01:46 EST 1995
|
||
f2c.ps: adjust discussion of -P on p. 7 to reflect a change made
|
||
3 Feb. 1993: -P no longer implies -A.
|
||
|
||
Fri Apr 21 18:35:00 EDT 1995
|
||
fc script: remove absolute paths (since PATH specifies only standard
|
||
places). On most systems, it's still necessary to adjust the PATH
|
||
assignment at the start of fc to fit the local conventions.
|
||
|
||
Fri May 26 10:03:17 EDT 1995
|
||
fc script: add recognition of -P and .P files.
|
||
libi77: iio.c: z_wnew: fix bug in handling T format items in internal
|
||
writes whose last item is written to an earlier position than some
|
||
previous item.
|
||
|
||
Wed May 31 11:39:48 EDT 1995
|
||
libf77: added subroutine exit(rc) (with integer return code rc),
|
||
which works like a stop statement but supplies rc as the program's
|
||
return code.
|
||
|
||
Fri Jun 2 11:56:50 EDT 1995
|
||
Fix memory fault in
|
||
parameter (x=2.)
|
||
data x /2./
|
||
end
|
||
This now elicits two error messages; the second ("too many
|
||
initializers"), though not desirable, seems hard to eliminate
|
||
without considerable hassle.
|
||
|
||
Mon Jul 17 23:24:20 EDT 1995
|
||
Fix botch in simplifying constants in certain complex
|
||
expressions. Example:
|
||
subroutine foo(s,z)
|
||
double complex z
|
||
double precision s, M, P
|
||
parameter ( M = 100.d0, P = 2.d0 )
|
||
z = M * M / s * dcmplx (1.d0, P/M)
|
||
*** The imaginary part of z was miscomputed ***
|
||
end
|
||
Under -ext, complain about nonintegral dimensions.
|
||
|
||
Fri Jul 21 11:18:36 EDT 1995
|
||
Fix glitch on line 159 of init.c: change
|
||
"(shortlogical *)0)",
|
||
to
|
||
"(shortlogical *)0",
|
||
This affects multiple entry points when some but not all have
|
||
arguments of type logical*2.
|
||
libi77: adjust lwrite.c, wref.c, wrtfmt.c so compiling with
|
||
-DWANT_LEAD_0 causes formatted writes of floating-point numbers of
|
||
magnitude < 1 to have an explicit 0 before the decimal point (if the
|
||
field-width permits it). Note that the Fortran 77 Standard leaves it
|
||
up to the implementation whether to supply these superfluous zeros.
|
||
|
||
Tue Aug 1 09:25:56 EDT 1995
|
||
Permit real (or double precision) parameters in dimension expressions.
|
||
|
||
Mon Aug 7 08:04:00 EDT 1995
|
||
Append "_eqv" rather than just "_" to names that that appear in
|
||
EQUIVALENCE statements as well as structs in f2c.h (to avoid a
|
||
conflict when these names also name common blocks).
|
||
|
||
Tue Aug 8 12:49:02 EDT 1995
|
||
Modify yesterday's change: merge st_fields with c_keywords, to
|
||
cope with equivalences introduced to permit initializing numeric
|
||
variables with character data. DATA statements causing these
|
||
equivalences can appear after executable statements, so the only
|
||
safe course is to rename all local variable with names in the
|
||
former st_fields list. This has the unfortunate side effect that
|
||
the common local variable "i" will henceforth be renamed "i__".
|
||
|
||
Wed Aug 30 00:19:32 EDT 1995
|
||
libf77: add F77_aloc, now used in s_cat and system_ (to allocate
|
||
memory and check for failure in so doing).
|
||
libi77: improve MSDOS logic in backspace.c.
|
||
|
||
Wed Sep 6 09:06:19 EDT 1995
|
||
libf77: Fix return type of system_ (integer) under -DKR_headers.
|
||
libi77: Move some f_init calls around for people who do not use
|
||
libF77's main(); now open and namelist read statements that are the
|
||
first I/O statements executed should work right in that context.
|
||
Adjust namelist input to treat a subscripted name whose subscripts do
|
||
not involve colons similarly to the name without a subscript: accept
|
||
several values, stored in successive elements starting at the
|
||
indicated subscript. Adjust namelist output to quote character
|
||
strings (avoiding confusion with arrays of character strings).
|
||
|
||
Thu Sep 7 00:36:04 EDT 1995
|
||
Fix glitch in integer*8 exponentiation function: it's pow_qq, not
|
||
pow_qi.
|
||
libi77: fix some bugs with -DAllow_TYQUAD (for integer*8); when
|
||
looking for the &name that starts NAMELIST input, treat lines whose
|
||
first nonblank character is something other than &, $, or ? as
|
||
comment lines (i.e., ignore them), unless rsne.c is compiled with
|
||
-DNo_Namelist_Comments.
|
||
|
||
Thu Sep 7 09:05:40 EDT 1995
|
||
libi77: rdfmt.c: one more tweak for -DAllow_TYQUAD.
|
||
|
||
Tue Sep 19 00:03:02 EDT 1995
|
||
Adjust handling of floating-point subscript bounds (a questionable
|
||
f2c extension) so subscripts in the generated C are of integral type.
|
||
Move #define of roundup to proc.c (where its use is commented out);
|
||
version.c left at 19950918.
|
||
|
||
Wed Sep 20 17:24:19 EDT 1995
|
||
Fix bug in handling ichar() under -h.
|
||
|
||
Thu Oct 5 07:52:56 EDT 1995
|
||
libi77: wrtfmt.c: fix bug with t editing (f__cursor was not always
|
||
zeroed in mv_cur).
|
||
|
||
Tue Oct 10 10:47:54 EDT 1995
|
||
Under -ext, warn about X**-Y and X**+Y. Following the original f77,
|
||
f2c treats these as X**(-Y) and X**(+Y), respectively. (They are not
|
||
allowed by the official Fortran 77 Standard.) Some Fortran compilers
|
||
give a bizarre interpretation to larger contexts, making multiplication
|
||
noncommutative: they treat X**-Y*Z as X**(-Y*Z) rather than X**(-Y)*Z,
|
||
which, following the rules of Fortran 77, is the same as (X**(-Y))*Z.
|
||
|
||
Wed Oct 11 13:27:05 EDT 1995
|
||
libi77: move defs of f__hiwater, f__svic, f__icptr from wrtfmt.c
|
||
to err.c. This should work around a problem with buggy loaders and
|
||
sometimes leads to smaller executable programs.
|
||
|
||
Sat Oct 21 23:54:22 EDT 1995
|
||
Under -h, fix bug in the treatment of ichar('0') in arithmetic
|
||
expressions.
|
||
Demote to -dneg (a new command-line option not mentioned in the
|
||
man page) imitation of the original f77's treatment of unary minus
|
||
applied to a REAL operand (yielding a DOUBLE PRECISION result).
|
||
Previously this imitation (which was present for debugging) occurred
|
||
under (the default) -!R. It is still suppressed by -R.
|
||
|
||
Tue Nov 7 23:52:57 EST 1995
|
||
Adjust assigned GOTOs to honor SAVE declarations.
|
||
Add comments about ranlib to lib[FI]77/README and makefile.
|
||
|
||
Tue Dec 19 22:54:06 EST 1995
|
||
libf77: s_cat.c: fix bug when 2nd or later arg overlaps lhs.
|
||
|
||
Tue Jan 2 17:54:00 EST 1996
|
||
libi77: rdfmt.c: move #include "ctype.h" up before "stdlib.h"; no
|
||
change to Version.c.
|
||
|
||
Sun Feb 25 22:20:20 EST 1996
|
||
Adjust expr.c to permit raising the integer constants 1 and -1 to
|
||
negative constant integral powers.
|
||
Avoid faulting when -T and -d are not followed by a directory name
|
||
(immediately, without intervening spaces).
|
||
|
||
Wed Feb 28 12:49:01 EST 1996
|
||
Fix a glitch in handling complex parameters assigned a "wrong" type.
|
||
Example:
|
||
complex d, z
|
||
parameter(z = (0d0,0d0))
|
||
data d/z/ ! elicited "non-constant initializer"
|
||
call foo(d)
|
||
end
|
||
|
||
Thu Feb 29 00:53:12 EST 1996
|
||
Fix bug in handling character parameters assigned a char() value.
|
||
Example:
|
||
character*2 b,c
|
||
character*1 esc
|
||
parameter(esc = char(27))
|
||
integer i
|
||
data (b(i:i),i=1,2)/esc,'a'/
|
||
data (c(i:i),i=1,2)/esc,'b'/ ! memory fault
|
||
call foo(b,c)
|
||
end
|
||
|
||
Fri Mar 1 23:44:51 EST 1996
|
||
Fix glitch in evaluating .EQ. and .NE. when both operands are
|
||
logical constants (.TRUE. or .FALSE.).
|
||
|
||
Fri Mar 15 17:29:54 EST 1996
|
||
libi77: lread.c, rsfe.c: honor END= in READ stmts with empty iolist.
|
||
|
||
Tue Mar 19 23:08:32 EST 1996
|
||
lex.c: arrange for a "statement" consisting of a single short bogus
|
||
keyword to elicit an error message showing the whole keyword. The
|
||
error message formerly omitted the last letter of the bad keyword.
|
||
libf77: s_cat.c: supply missing break after overlap detection.
|
||
|
||
Mon May 13 23:35:26 EDT 1996
|
||
Recognize Fortran 90's /= as a synonym for .NE.. (<> remains a
|
||
synonym for .NE..)
|
||
Emit an empty int function of no arguments to supply an external
|
||
name to named block data subprograms (so they can be called somewhere
|
||
to force them to be loaded from a library).
|
||
Fix bug (memory fault) in handling the following illegal Fortran:
|
||
parameter(i=1)
|
||
equivalence(i,j)
|
||
end
|
||
Treat cdabs, cdcos, cdexp, cdlog, cdsin, and cdsqrt as synonyms for
|
||
the double complex intrinsics zabs, zcos, zexp, zlog, zsin, and zsqrt,
|
||
respectively, unless -cd is specified.
|
||
Recognize the Fortran 90 bit-manipulation intrinsics btest, iand,
|
||
ibclr, ibits, ibset, ieor, ior, ishft, and ishftc, unless -i90 is
|
||
specified. Note that iand, ieor, and ior are thus now synonyms for
|
||
"and", "xor", and "or", respectively.
|
||
Add three macros (bit_test, bit_clear, bit_set) to f2c.h for use
|
||
with btest, ibclr, and ibset, respectively. Add new functions
|
||
[lq]bit_bits, [lq]bit_shift, and [lq]_bit_cshift to libF77 for
|
||
use with ibits, ishft, and ishftc, respectively.
|
||
Add integer function ftell(unit) (returning -1 on error) and
|
||
subroutine fseek(unit, offset, whence, *) to libI77 (with branch to
|
||
label * on error).
|

Tue May 14 23:21:12 EDT 1996
|
||
Fix glitch (possible memory fault, or worse) in handling multiple
|
||
entry points with names over 28 characters long.
|
||
|
||
Mon Jun 10 01:20:16 EDT 1996
|
||
Update netlib E-mail and ftp addresses in f2c/readme and
|
||
f2c/src/readme (which are different files) -- to reflect the upcoming
|
||
breakup of AT&T.
|
||
libf77: trivial tweaks to F77_aloc.c and system_.c; Version.c not
|
||
changed.
|
||
libi77: Adjust rsli.c and lread.c so internal list input with too
|
||
few items in the input string will honor end= .
|
||
|
||
Mon Jun 10 22:59:57 EDT 1996
|
||
Add Bits_per_Byte to sysdep.h and adjust definition of Table_size
|
||
to depend on Bits_per_Byte (forcing Table_size to be a power of 2); in
|
||
lex.c, change "comstart[c & 0xfff]" to "comstart[c & (Table_size-1)]"
|
||
to avoid an out-of-range subscript on end-of-file.
|
||
|
||
Wed Jun 12 00:24:28 EDT 1996
|
||
Fix bug in output.c (dereferencing a freed pointer) revealed in
|
||
print * !np in out_call in output.c clobbered by free
|
||
end !during out_expr.
|
||
|
||
Wed Jun 19 08:12:47 EDT 1996
|
||
f2c.h: add types uinteger, ulongint (for libF77); add qbit_clear
|
||
and qbit_set macros (in a commented-out section) for integer*8.
|
||
For integer*8, use qbit_clear and qbit_set for ibclr and ibset.
|
||
libf77: add casts to unsigned in [lq]bitshft.c.
|
||
|
||
Thu Jun 20 13:30:43 EDT 1996
|
||
Complain at character*(*) in common (rather than faulting).
|
||
Fix bug in recognizing hex constants that start with "16#" (e.g.,
|
||
16#1234abcd, which is a synonym for z'1234abcd').
|
||
Fix bugs in constant folding of expressions involving btest, ibclr,
|
||
and ibset.
|
||
Fix bug in constant folding of rshift(16#80000000, -31) (on a 32-bit
|
||
machine; more generally, the bug was in constant folding of
|
||
rshift(ibset(0,NBITS-1), 1-NBITS) when f2c runs on a machine with
|
||
long ints having NBITS bits.
|
||
|
||
Mon Jun 24 07:58:53 EDT 1996
|
||
Adjust struct Literal and newlabel() function to accommodate huge
|
||
source files (with more than 32767 newlabel() invocations).
|
||
Omit .c file when the .f file has a missing final end statement.
|
||
|
||
Wed Jun 26 14:00:02 EDT 1996
|
||
libi77: Add discussion of MXUNIT (highest allowed Fortran unit number)
|
||
to libI77/README.
|
||
|
||
Fri Jun 28 14:16:11 EDT 1996
|
||
Fix glitch with -onetrip: the temporary variable used for nonconstant
|
||
initial loop variable values was recycled too soon. Example:
|
||
do i = j+1, k
|
||
call foo(i+1) ! temp for j+1 was reused here
|
||
enddo
|
||
end
|
||
|
||
Tue Jul 2 16:11:27 EDT 1996
|
||
formatdata.c: add a 0 to the end of the basetype array (for TYBLANK)
|
||
(an omission that was harmless on most machines).
|
||
expr.c: fix a dereference of NULL that was only possible with buggy
|
||
input, such as
|
||
subroutine $sub(s) ! the '$' is erroneous
|
||
character s*(*)
|
||
s(1:) = ' '
|
||
end
|
||
|
||
Sat Jul 6 00:44:56 EDT 1996
|
||
Fix glitch in the intrinsic "real" function when applied to a
|
||
complex (or double complex) variable and passed as an argument to
|
||
some intrinsic functions. Example:
|
||
complex a
|
||
b = sqrt(a)
|
||
end
|
||
Fix glitch (only visible if you do not use f2c's malloc and the
|
||
malloc you do use is defective in the sense that malloc(0) returns 0)
|
||
in handling include files that end with another include (perhaps
|
||
followed by comments).
|
||
Fix glitch with character*(*) arguments named "h" and "i" when
|
||
the body of the subroutine invokes the intrinsic LEN function.
|
||
Arrange that after a previous "f2c -P foo.f" has produced foo.P,
|
||
running "f2c foo.P foo.f" will produce valid C when foo.f contains
|
||
call sub('1234')
|
||
end
|
||
subroutine sub(msg)
|
||
end
|
||
Specifically, the length argument in "call sub" is now suppressed.
|
||
With or without foo.P, it is also now suppressed when the order of
|
||
subprograms in file foo.f is reversed:
|
||
subroutine sub(msg)
|
||
end
|
||
call sub('1234')
|
||
end
|
||
Adjust copyright notices to reflect AT&T breakup.
|
||
|
||
Wed Jul 10 09:25:49 EDT 1996
|
||
Fix bug (possible memory fault) in handling erroneously placed
|
||
and inconsistent declarations. Example that faulted:
|
||
character*1 w(8)
|
||
call foo(w)
|
||
end
|
||
subroutine foo(m)
|
||
data h /0.5/
|
||
integer m(2) ! should be before data
|
||
end
|
||
Fix bug (possible fault) in handling illegal "if" constructions.
|
||
Example (that faulted):
|
||
subroutine foo(i,j)
|
||
if (i) then ! bug: i is integer, not logical
|
||
else if (j) then ! bug: j is integer, not logical
|
||
endif
|
||
end
|
||
Fix glitch with character*(*) argument named "ret_len" to a
|
||
character*(*) function.
|
||
|
||
Wed Jul 10 23:04:16 EDT 1996
|
||
Fix more glitches in the intrinsic "real" function when applied to a
|
||
complex (or double complex) variable and passed as an argument to
|
||
some intrinsic functions. Example:
|
||
complex a, b
|
||
r = sqrt(real(conjg(a))) + sqrt(real(a*b))
|
||
end
|
||
|
||
Thu Jul 11 17:27:16 EDT 1996
|
||
Fix a memory fault associated with complicated, illegal input.
|
||
Example:
|
||
subroutine goo
|
||
character a
|
||
call foo(a) ! inconsistent with subsequent def and call
|
||
end
|
||
subroutine foo(a)
|
||
end
|
||
call foo(a)
|
||
end
|
||
|
||
Wed Jul 17 19:18:28 EDT 1996
|
||
Fix yet another case of intrinsic "real" applied to a complex
|
||
argument. Example:
|
||
complex a(3)
|
||
x = sqrt(real(a(2))) ! gave error message about bad tag
|
||
end
|
||
|
||
Mon Aug 26 11:28:57 EDT 1996
|
||
Tweak sysdep.c for non-Unix systems in which process ID's can be
|
||
over 5 digits long.
|
||
|
||
Tue Aug 27 08:31:32 EDT 1996
|
||
Adjust the ishft intrinsic to use unsigned right shifts. (Previously,
|
||
a negative constant second operand resulted in a possibly signed shift.)
|
||
|
||
Thu Sep 12 14:04:07 EDT 1996
|
||
equiv.c: fix glitch with -DKR_headers.
|
||
libi77: fmtlib.c: fix bug in printing the most negative integer.
|
||
|
||
Fri Sep 13 08:54:40 EDT 1996
|
||
Diagnose some illegal appearances of substring notation.
|
||
|
||
Tue Sep 17 17:48:09 EDT 1996
|
||
Fix fault in handling some complex parameters. Example:
|
||
subroutine foo(a)
|
||
double complex a, b
|
||
parameter(b = (0,1))
|
||
a = b ! f2c faulted here
|
||
end
|
||
|
||
Thu Sep 26 07:47:10 EDT 1996
|
||
libi77: fmt.h: for formatted writes of negative integer*1 values,
|
||
make ic signed on ANSI systems. If formatted writes of integer*1
|
||
values trouble you when using a K&R C compiler, switch to an ANSI
|
||
compiler or use a compiler flag that makes characters signed.
|
||
|
||
Tue Oct 1 14:41:36 EDT 1996
|
||
Give a better error message when dummy arguments appear in data
|
||
statements.
|
||
|
||
Thu Oct 17 13:37:22 EDT 1996
|
||
Fix bug in typechecking arguments to character and complex (or
|
||
double complex) functions; the bug could cause length arguments
|
||
for character arguments to be omitted on invocations appearing
|
||
textually after the first invocation. For example, in
|
||
subroutine foo
|
||
character c
|
||
complex zot
|
||
call goo(zot(c), zot(c))
|
||
end
|
||
the length was omitted from the second invocation of zot, and
|
||
there was an erroneous error message about inconsistent calling
|
||
sequences.
|
||
|
||
Wed Dec 4 13:59:14 EST 1996
|
||
Fix bug revealed by
|
||
subroutine test(cdum,rdum)
|
||
complex cdum
|
||
rdum=cos(real(cdum)) ! "Unexpected tag 3 in opconv_fudge"
|
||
end
|
||
Fix glitch in parsing "DO 10 D0 = 1, 10".
|
||
Fix glitch in parsing
|
||
real*8 x
|
||
real*8 x ! erroneous "incompatible type" message
|
||
call foo(x)
|
||
end
|
||
|
||
Mon Dec 9 23:15:02 EST 1996
|
||
Fix glitch in parameter adjustments for arrays whose lower
|
||
bound depends on a scalar argument. Example:
|
||
subroutine bug(p,z,m,n)
|
||
integer z(*),m,n
|
||
double precision p(z(m):z(m) + n) ! p_offset botched
|
||
call foo(p(0), p(n))
|
||
end
|
||
libi77: complain about non-positive rec= in direct read and write
|
||
statements.
|
||
libf77: trivial adjustments; Version.c not changed.
|
||
|
||
Wed Feb 12 00:18:03 EST 1997
|
||
output.c: fix (seldom problematic) glitch in out_call: put parens
|
||
around the ... in a test of the form "if (q->tag == TADDR && ...)".
|
||
vax.c: fix bug revealed in the "psi_offset =" assignment in the
|
||
following example:
|
||
subroutine foo(psi,m)
|
||
integer z(100),m
|
||
common /a/ z
|
||
double precision psi(z(m):z(m) + 10)
|
||
call foo(m+1, psi(0),psi(10))
|
||
end
|
||
|
||
Mon Feb 24 23:44:54 EST 1997
|
||
For consistency with f2c's current treatment of adjacent character
|
||
strings in FORMAT statements, recognize a Hollerith string following
|
||
a string (and merge adjacent strings in FORMAT statements).
|
||
|
||
Wed Feb 26 13:41:11 EST 1997
|
||
New libf2c.zip, a combination of the libf77 and libi77 bundles (and
|
||
available only by ftp).
|
||
libf77: adjust functions with a complex output argument to permit
|
||
aliasing it with input arguments. (For now, at least, this is just
|
||
for possible benefit of g77.)
|
||
libi77: tweak to ftell_.c for systems with strange definitions of
|
||
SEEK_SET, etc.
|
||
|
||
Tue Apr 8 20:57:08 EDT 1997
|
||
libf77: [cz]_div.c: tweaks invisible on most systems (that may
|
||
improve things slightly with optimized compilation on systems that use
|
||
gratuitous extra precision).
|
||
libi77: fmt.c: adjust to complain at missing numbers in formats
|
||
(but still treat missing ".nnn" as ".0").
|
||
|
||
Fri Apr 11 14:05:57 EDT 1997
|
||
libi77: err.c: attempt to make stderr line buffered rather than
|
||
fully buffered. (Buffering is needed for format items T and TR.)
|
||
|
||
Thu Apr 17 22:42:43 EDT 1997
|
||
libf77: add F77_aloc.o to makefile (and makefile.u in libf2c.zip).
|
||
|
||
Fri Apr 25 19:32:09 EDT 1997
|
||
libf77: add [de]time_.c (which may give trouble on some systems).
|
||
|
||
Tue May 27 09:18:52 EDT 1997
|
||
libi77: ftell_.c: fix typo that caused the third argument to be
|
||
treated as 2 on some systems.
|
||
|
||
Mon Jun 9 00:04:37 EDT 1997
|
||
libi77 (and libf2c.zip): adjust include order in err.c lread.c wref.c
|
||
rdfmt.c to include fmt.h (etc.) after system includes. Version.c not
|
||
changed.
|
||
|
||
Mon Jul 21 16:04:54 EDT 1997
|
||
proc.c: fix glitch in logic for "nonpositive dimension" message.
|
||
libi77: inquire.c: always include string.h (for possible use with
|
||
-DNON_UNIX_STDIO); Version.c not changed.
|
||
|
||
Thu Jul 24 17:11:23 EDT 1997
|
||
Tweak "Notice" to reflect the AT&T breakup -- we missed it when
|
||
updating the copyright notices in the source files last summer.
|
||
Adjust src/makefile so malloc.o is not used by default, but can
|
||
be specified with "make MALLOC=malloc.o".
|
||
Add comments to src/README about the "CRAY" T3E.
|
||
|
||
Tue Aug 5 14:53:25 EDT 1997
|
||
Add definition of calloc to malloc.c; this makes f2c's malloc
|
||
work on some systems where trouble hitherto arose because references
|
||
to calloc brought in the system's malloc. (On sensible systems,
|
||
calloc is defined separately from malloc. To avoid confusion on
|
||
other systems, f2c/malloc.c now defines calloc.)
|
||
libi77: lread.c: adjust to accord with a change to the Fortran 8X
|
||
draft (in 1990 or 1991) that rescinded permission to elide quote marks
|
||
in namelist input of character data; to get the old behavior, compile
|
||
with F8X_NML_ELIDE_QUOTES #defined. wrtfmt.o: wrt_G: tweak to print
|
||
the right number of 0's for zero under G format.
|
||
|
||
Sat Aug 16 05:45:32 EDT 1997
|
||
libi77: iio.c: fix bug in internal writes to an array of character
|
||
strings that sometimes caused one more array element than required by
|
||
the format to be blank-filled. Example: format(1x).
|
||
|
||
Wed Sep 17 00:39:29 EDT 1997
|
||
libi77: fmt.[ch] rdfmt.c wrtfmt.c: tweak struct syl for machines
|
||
with 64-bit pointers and 32-bit ints that did not 64-bit align
|
||
struct syl (e.g., Linux on the DEC Alpha). This change should be
|
||
invisible on other machines.
|
||
|
||
Sun Sep 21 22:05:19 EDT 1997
|
||
libf77: [de]time_.c (Unix systems only): change return type to double.
|
||
|
||
Thu Dec 4 22:10:09 EST 1997
|
||
Fix bug with handling large blocks of comments (over 4k); parts of the
|
||
second and subsequent blocks were likely to be lost (not copied into
|
||
comments in the resulting C). Allow comment lines to be longer before
|
||
breaking them.
|
||
|
||
Mon Jan 19 17:19:27 EST 1998
|
||
makefile: change the rule for making gram.c to one for making gram1.c;
|
||
henceforth, asking netlib to "send all from f2c/src" will bring you a
|
||
working gram.c. Nowadays there are simply too many broken versions of
|
||
yacc floating around.
|
||
libi77: backspace.c: for b->ufmt==0, change sizeof(int) to
|
||
sizeof(uiolen). On machines where this would make a difference, it is
|
||
best for portability to compile libI77 with -DUIOLEN_int, which will
|
||
render the change invisible.
|
||
|
||
Tue Feb 24 08:35:33 EST 1998
|
||
makefile: remove gram.c from the "make clean" rule.
|
||
|
||
Wed Feb 25 08:29:39 EST 1998
|
||
makefile: change CFLAGS assignment to -O; add "veryclean" rule.
|
||
|
||
Wed Mar 4 13:13:21 EST 1998
|
||
libi77: open.c: fix glitch in comparing file names under
|
||
-DNON_UNIX_STDIO.
|
||
|
||
Mon Mar 9 23:56:56 EST 1998
|
||
putpcc.c: omit an unnecessary temporary variable in computing
|
||
(expr)**3.
|
||
libf77, libi77: minor tweaks to make some C++ compilers happy;
|
||
Version.c not changed.
|
||
|
||
Wed Mar 18 18:08:47 EST 1998
|
||
libf77: minor tweaks to [ed]time_.c; Version.c not changed.
|
||
libi77: endfile.c, open.c: acquire temporary files from tmpfile(),
|
||
unless compiled with -DNON_ANSI_STDIO, which uses mktemp().
|
||
New buffering scheme independent of NON_UNIX_STDIO for handling T
|
||
format items. Now -DNON_UNIX_STDIO is no longer be necessary for
|
||
Linux, and libf2c no longer causes stderr to be buffered -- the former
|
||
setbuf or setvbuf call for stderr was to make T format items work.
|
||
open.c: use the Posix access() function to check existence or
|
||
nonexistence of files, except under -DNON_POSIX_STDIO, where trial
|
||
fopen calls are used. In open.c, fix botch in changes of 19980304.
|
||
libf2c.zip: the PC makefiles are now set for NT/W95, with comments
|
||
about changes for DOS.
|
||
|
||
Fri Apr 3 17:22:12 EST 1998
|
||
Adjust fix of 19960913 to again permit substring notation on
|
||
character variables in data statements.
|
||
|
||
Sun Apr 5 19:26:50 EDT 1998
|
||
libi77: wsfe.c: make $ format item work: this was lost in the changes
|
||
of 17 March 1998.
|
||
|
||
Sat May 16 19:08:51 EDT 1998
|
||
Adjust output of ftnlen constants: rather than appending L,
|
||
prepend (ftnlen). This should make the resulting C more portable,
|
||
e.g., to systems (such as DEC Alpha Unix systems) on which long
|
||
may be longer than ftnlen.
|
||
Adjust -r so it also casts REAL expressions passed to intrinsic
|
||
functions to REAL.
|
||
|
||
Wed May 27 16:02:35 EDT 1998
|
||
libf2c.zip: tweak description of compiling libf2c for INTEGER*8
|
||
to accord with makefile.u rather than libF77/makefile.
|
||
|
||
Thu May 28 22:45:59 EDT 1998
|
||
libi77: backspace.c dfe.c due.c iio.c lread.c rsfe.c sue.c wsfe.c:
|
||
set f__curunit sooner so various error messages will correctly
|
||
identify the I/O unit involved.
|
||
libf2c.zip: above, plus tweaks to PC makefiles: for some purposes,
|
||
it's still best to compile with -DMSDOS (even for use with NT).
|
||
|
||
Thu Jun 18 01:22:52 EDT 1998
|
||
libi77: lread.c: modified so floating-point numbers (containing
|
||
either a decimal point or an exponent field) are treated as errors
|
||
when they appear as list input for integer data. Compile lread.c with
|
||
-DALLOW_FLOAT_IN_INTEGER_LIST_INPUT to restore the old behavior.
|
||
|
||
Mon Aug 31 10:38:54 EDT 1998
|
||
formatdata.c: if possible, and assuming doubles must be aligned on
|
||
double boundaries, use existing holes in DATA for common blocks to
|
||
force alignment of the block. For example,
|
||
block data
|
||
common /abc/ a, b
|
||
double precision a
|
||
integer b(2)
|
||
data b(2)/1/
|
||
end
|
||
used to generate
|
||
struct {
|
||
integer fill_1[3];
|
||
integer e_2;
|
||
doublereal e_3;
|
||
} abc_ = { {0}, 1, 0. };
|
||
and now generates
|
||
struct {
|
||
doublereal fill_1[1];
|
||
integer fill_2[1];
|
||
integer e_3;
|
||
} abc_ = { {0}, {0}, 1 };
|
||
In the old generated C, e_3 was added to force alignment; in the new C,
|
||
fill_1 does this job.
|
||
|
||
Mon Sep 7 19:48:51 EDT 1998
|
||
libi77: move e_wdfe from sfe.c to dfe.c, where it was originally.
|
||
Why did it ever move to sfe.c?
|
||
|
||
Tue Sep 8 10:22:50 EDT 1998
|
||
Treat dreal as a synonym for dble unless -cd is specified on the
|
||
command line.
|
||
|
||
Sun Sep 13 22:23:41 EDT 1998
|
||
format.c: fix bug in writing prototypes under f2c -A ... *.P:
|
||
under some circumstances involving external functions with no known
|
||
type, a null pointer was passed to printf.
|
||
|
||
Tue Oct 20 23:25:54 EDT 1998
|
||
Comments added to libf2c/README and libF77/README, pointing out
|
||
the need to modify signal1.h on some systems.
|
||
|
||
Wed Feb 10 22:59:52 EST 1999
|
||
defs.h lex.c: permit long names (up to at least roughly

libf2c: endfile.c, lread.c, signal1.h0: minor tweaks to make some
|
||
(C++) compilers happier; f77_aloc.c: make exit_() visible to C++
|
||
compilers. Version strings not changed.

Modify f2c (exec.c, expr.c) to diagnose incorrect mixing of types
|
||
when (f2c extended) intrinsic functions are involved, as in
|
||
(not(17) .and. 4). Catching this in the first executable statement
|
||
is a bit tricky, as some checking must be postponed until all statement
|
||
function declarations have been parsed. Thus there is a chance of
|
||
today's changes introducing bugs under (let us hope) unusual conditions.

lex.c: tweak to get the file name right in error messages caused
|
||
by statements just after a # nnn "filename" line emitted by the C
|
||
preprocessor. (The trouble is that the line following the # nnn line
|
||
must be read to see if it is a continuation of the stuff that preceded
|
||
the # nnn line.) When # nnn "filename" lines appear among the lines
|
||
for a Fortran statement, the filename reported in an error message for
|
||
the statement should now be the file that was current when the first
|
||
line of the statement was read.

libf77, libi77, libf2c.zip: make getenv_() more portable (call
|
||
getenv() rather than knowing about char **environ); adjust some
|
||
complex intrinsics to work with overlapping arguments (caused by
|
||
inappropriate use of equivalence); open.c: get "external" versus
|
||
"internal" right in the error message if a file cannot be opened;
|
||
err.c: cast a pointer difference to (int) for %d; rdfmt.c: omit
|
||
fixed-length buffer that could be overwritten by formats Inn or Lnn
|
||
with nn > 83.
|

|

Mon May 3 13:14:07 EDT 1999
|
||
"Invisible" changes to omit a few compiler warnings in f2c and
|
||
libf2c; two new casts in libf2c/open.c that matter with 64-bit longs,
|
||
and one more tweak (libf2c/c_log.c) for pathological equivalences.
|
||
Minor update to "fc" script: new -L flag and comment correction.

libf2c.zip: rename backspace.c backspac.c, and fix a glitch in it
|
||
-- b->ufd may change in t_runc(). (For now, it's still backspace.c
|
||
in the libi77 bundle.)

|

libf2c.zip, libi77: rsne.c: fix bug in namelist input: a misplaced
|
||
increment could cause wrong array elements to be assigned; e.g.,
|
||
"&input k(5)=10*1 &end" assigned k(5) and k(15 .. 23).
