|
|
|
|
* doc/Makefile.in (gperf.dvi, clean): Remove gperf.cps.
|
|
(install, installdirs, uninstall): Don't install gperf.dvi. The

|
can do this directly off the source distribution.
|
|
(DVIPS): Use "-D600" instead of "-Pljfour", for portability.
|
|
|
|
1998-05-20 Akim Demaille <demaille@inf.enst.fr>
|
|
|
|

|
|
(Options): Declare also the long form of the options.

|
|
|
|

|
|
|
|
* gperf-2.7 released.
|
|
|
|
Sat May 2 12:31:51 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|
|
|
|
* src/version.cc (version_string): Remove the "(C++ version)" suffix.
|
|
It's redundant: the early C versions of gperf are called cperf.
|
|
Reported by Karl Berry.
|
|
* src/option.cc (Options::operator()): Trim the output of "gperf -v".
|
|
|
|
Thu Apr 16 13:22:16 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|
|
|
|
* lib/Makefile.in, src/Makefile.in: Don't use $(TARGET_ARCH).
|
|
Solaris "make" sets it to a value not understood by "cc".
|
|
|
|
Wed Apr 15 23:52:14 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|
|
|
|
* lib/Makefile.in, src/Makefile.in: Don't use implicit rules. Don't
|
|
use $<. AIX "make" and OSF/1 "make" have problems with both.
|
|
* src/gen-perf.cc, src/key-list.cc: Cast free() argument to char*,
|
|
otherwise it doesn't compile on SunOS 4.
|
|
* src/key-list.h: Declare structs outside of other declarations,
|
|
needed for OSF/1 cxx 5.5.
|
|
* lib/getopt.h: Use prototypes if __STDC__ || __cplusplus.
|
|
Don't give a prototype for getopt(), to avoid error on SunOS 4.
|
|
* lib/getopt.c: Declare strncmp, to avoid warnings.
|
|
|
|
Tue Apr 14 23:24:07 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|
|
|
|
* lib/GetOpt.{h,cc}: Remove files.
|
|
* lib/getopt.{h,c}, lib/getopt1.c: New files, from GNU libc.
|
|
* lib/configure.in (AC_INIT): Search for hash.cc, not GetOpt.cc.
|
|
* lib/Makefile.in (OBJECTS): Remove GetOpt.o, add getopt.o, getopt1.o.
|
|
(getopt.o, getopt1.o, hash.o): Use explicit building rules. Some
|
|
"make"s don't support to have both implicit rules for "%.o : %.c"
|
|
and "%.o : %.cc" in the same Makefile.
|
|
* lib/hash.{h,cc}: Remove #pragma; there are no templates here.
|
|
* src/option.h (Options::usage): Remove.
|
|
(Options::short_usage, Options::long_usage): Declare.
|
|
* src/option.cc (Options::usage): Remove.
|
|
(Options::short_usage, Options::long_usage): New functions.
|
|
(long_options): New array.
|
|
(Options::operator()): Use getopt_long instead of GetOpt::operator(),
|
|
change all references to GetOpt members.
|
|
|
|
* src/std-err.{h,cc}: Remove files.
|
|
* src/gen-perf.cc, src/key-list.cc, list-node.cc, new.cc, options.cc:
|
|
Call fprintf(stderr) instead of Std_Err::report_error().
|
|
* src/key-list.h, src/list-node.h, src/options.h: Don't use class
|
|
Std_Err any more.
|
|
* src/option.cc (program_name): New variable.
|
|
* src/Makefile.in: Remove STD_ERR_H.
|
|
(OBJECTS): Remove std-err.o.
|
|
|
|
Mon Mar 23 01:03:35 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|
|
|
|
* aclocal.m4, {lib,src,tests}/configure.in: Remove CL_CC_WORKS and
|
|
CL_CXX_WORKS, already contained in autoconf 2.12.
|
|
|
|
* src/gen-perf.cc, src/key-list.cc: Move some code from
|
|
Gen_Perf::Gen_Perf() to Key_List::output().
|
|
* src/Makefile.in: Update dependencies.
|
|
|
|
* src/options.{h,cc}: Remove option "-p".
|
|
* src/key-list.cc (Key_List::set_output_types): Rewrite.
|
|
(default_array_type, default_return_type): Remove.
|
|
* src/key-list.cc: Adjust "const" handling.
|
|
+ With option "-t" [TYPE], don't emit wrong code if there is no
|
|
space before the struct's opening brace.
|
|
|
|
Sun Mar 22 16:59:15 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|
|
|
|
* src/key-list.{h,cc}: Completely reorganized the output routines.
|
|
Rewrote from scratch the output_switch() function. Use classes
|
|
(Output_Constants, Output_Expr, Output_Compare) for abstraction.
|
|
In particular:
|
|
+ Don't emit trailing whitespace and spurious blank lines.
|
|
+ Adjust indentation of the arrays.
|
|
+ Don't emit commas at the end of array initializers and
|
|
struct initializers.
|
|
+ With option "-l" [LENTABLE], compare the length before
|
|
fetching the word from memory.
|
|
+ With option "-S" [SWITCH], emit the comparison code just once,
|
|
not once in every switch statement.
|
|
+ With option "-S" [SWITCH], choose the right switch statement
|
|
through a binary search, not a linear search.
|
|
+ With option "-S" [SWITCH], emit straightforward comparisons
|
|
instead of switch statements with just one "case" label.
|
|
+ With options "-S -p -t" [SWITCH, POINTER, TYPE], don't emit
|
|
spurious empty elements at the beginning of the wordlist array.
|
|
+ With option "-D" [DUP] and not option "-S" [SWITCH], if there
|
|
is no more room for duplicate entries in the lookup array,
|
|
don't call `assert (i != 0)'. Instead, make the array larger :-)
|
|
+ With option "-D" [DUP], if there are no duplicates, don't
|
|
automatically fall back to the non-"-D" algorithm. If the user
|
|
wants the non-"-D" algorithm, he can just not specify "-D".
|
|
+ With option "-D" [DUP] and either options "-p -t" [POINTER, TYPE]
|
|
or not option "-S" [SWITCH], don't emit spurious empty elements
|
|
at the beginning of the wordlist array.
|
|
+ With option "-D" [DUP], simplify the detection and processing
|
|
of duplicate entries in the lookup array.
|
|
+ With options "-D -l" [DUP, LENTABLE] and not option "-S" [SWITCH],
|
|
don't forget to emit the lengthtable array.
|
|
+ With options "-D -l -S" [DUP, LENTABLE, SWITCH], don't forget to
|
|
compare the lengths before comparing the strings.
|
|
|
|
* src/gen-perf.cc: No need to include <assert.h>.
|
|
* src/options.cc: Likewise.
|
|
|
|
* src/options.cc: Don't use `errno' after freopen failed.
|
|
* src/std-err.cc: `report_error' doesn't call strerror(errno) any
|
|
more. No need to include <string.h> and <errno.h>.
|
|
|
|
* tests/Makefile.in (check-*): Any difference between .exp and .out
|
|
is a failure. Don't ignore whitespace differences.
|
|
|
|
* tests/Makefile.in (check-lang-syntax): Add some more checks.
|
|
|
|
Fri Mar 20 00:54:54 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|
|
|
|
* tests/jscript.gperf: Renamed from tests/javascript.gperf, because
|
|
of Minix and SVR2 14-character filename limit.
|
|
* src/key-list.cc (output_string): New function.
|
|
(Key_List::output_switch, Key_List::output_keyword_table): Call it.
|
|
|
|
* src/options.{h,icc,cc} (get_wordlist_name): New function. Add
|
|
option -W.
|
|
* src/key-list.cc (Key_List::output_switch,
|
|
Key_List::output_keyword_table, Key_List::output_lookup_function):
|
|
Use it.
|
|
Patch from William Bader <wbader@CSEE.Lehigh.Edu>.
|
|
|
|
* src/version.cc: Bump version number directly from 2.5 to 2.7,
|
|
because Schmidt's last release from 1991 carries version number 2.6.
|
|
|
|
Tue Jul 30 00:02:39 1991 Douglas C. Schmidt (schmidt at net4.ics.uci.edu)
|
|
|
|
* Fixed a small bug in the Key_List::output_keyword_table routine
|
|
that caused an extra newline to be printed if there where no
|
|
leading blank entries... (who cares, right?!)
|
|
|
|
Mon Jul 29 22:05:40 1991 Douglas C. Schmidt (schmidt at net4.ics.uci.edu)
|
|
|
|
* Modified the handling of the -E (emit enums rather than
|
|
#defines) option in conjunction with the -G option. Now, if -G
|
|
and -E are given the enums are generated outside the lookup
|
|
function, rather than within it!
|
|
|
|
Mon Apr 8 18:17:04 1991 Doug Schmidt (schmidt at net4.ics.uci.edu)
|
|
|
|
* Yucko, there was a bug in the handling of -c (and of course the
|
|
new -I command in key-list.cc). Apparently when I added the
|
|
super-duper hack that provided support for duplicate keys I
|
|
forgot to update the strcmp output...
|
|
|
|
Mon Mar 9 02:19:04 1998 Bruno Haible <bruno@linuix.mathematik.uni-karlsruhe.de>
|

|
|
libg++ into lib/.
|
|

|
|
aclocal.m4, with macros from CLISP and CLN. Added Makefile.devel.
|
|
* src/depend: Removed. Dependencies are now in src/Makefile.in.
|
|
|
|

|
|
src/bool-array.h and src/bool-array.cc.
|
|
* src/options.icc: New file, contains inline functions, from both
|
|
src/options.h and src/options.cc.

|
|
|
|
Changes (mostly from Peter Schauer) to permit compilation

|
using cfront 3.0 and otherwise be ARM-conforming.
|
|
* src/key-list.h: class Key_List must use public derivation

calls Std_Err::report_error).
|
|

fields from Key_List class, and use INT_MAX (etc) from limits.h.
|
|
* key-list.{h,cc}, options.{h,cc}, vectors.h: Removed all
|
|
uses of initialized const fields, as they are non-standard
|
|
- and their use was easy to do away with. Mostly, just
|
|
made the constants static non-fields in the .cc file.
|
|
|
|
Mon Nov 2 13:10:11 1992 Per Bothner (bothner@cygnus.com)
|
|
|
|
* tests/Makefile.in: When generating cinset.c, don't pass -C,
|
|
since -C assumes an ANSI compiler. Add the -C flag (with -a)
|
|
when generating test.out.3 instead.
|
|
* tests/expected.out.3: Update accordingly.
|
|
|
|
Wed Aug 12 11:47:54 1992 Per Bothner (bothner@cygnus.com)

|
|
|
|
Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
|
|
|
|
* Makefile.in, configure.in: removed traces of namesubdir,
|
|
-subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
|
|
copyrights to '92, changed some from Cygnus to FSF.
|
|
|
|
Sun Jan 26 19:21:58 1992 Per Bothner (bothner at cygnus.com)
|
|
|
|
* tests/Makefile.in: Use re-directed stdin instead of file
|
|
name in argv. This allows us to remove the filename
|
|
from the output, the expected output, and hence the diffs.
|
|
(Note that the input file is in $(srcdir), which we cannot
|
|
place in the expected out files.)
|
|
* tests/expected.out.[1235]: Edit out input filename,
|
|
to match new output.
|
|
|
|
Thu Jun 28 16:17:27 1990 Doug Schmidt (schmidt at brilliant)
|
|
|
|
* Wow, first fix on the new job! There was a dumb error
|
|
in Key_List::output_lookup_function, where I printed the
|
|
string "&wordlist[key]" instead of the correct "&wordlist[index]".
|
|
|
|
* Added a couple of #ifdefs for USG support.
|
|
|
|
Sun Jun 3 17:16:36 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Updated the version number to 2.5 and sent to Doug Lea for release
|
|
with the latest GNU libg++.
|
|
|
|
* Changed the error handling when a keyword file cannot be opened
|
|
(now calls perror).
|
|
|
|
Wed May 30 14:49:40 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Instrumented the source code with trace statements automagically
|
|
inserted using my new automated trace instrumentation tool!
|
|
|
|
Wed May 9 11:47:41 1990 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
|
|
|
* Really fixed the previous bug. Turns out that a small amount
|
|
of logic had to be duplicated to handle static links that occur
|
|
as part of dynamic link chains. What a pain!!!
|
|
|
|
Tue May 8 23:11:44 1990 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
|
|
|
* Fixed a stupid bug in Key_List::output_lookup_array that was
|
|
causing incorrect counts to be generated when there were both
|
|
static and dynamic links occurring for the same hash value.
|
|
Also simplified the code that performs the logic in this routine.
|
|
|
|
Mon Apr 30 17:37:24 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Fixed stupid bug in Key_List::output_lookup_array that was
|
|
making the generated lookup[] array contain `chars' even
|
|
when the values stored in the chars are greater than 127!
|
|
|
|
* Changed the behavior of the -G (global table) option so that it
|
|
will output the `length[]' array in the global scope along with
|
|
the `word_list[]' array.
|
|
|
|
* Fixed a stupid bug in Key_List::output_lookup_function that
|
|
would always output the complicated `duplicate-handling' lookup
|
|
logic, even when there were no duplicates in the input!
|
|
|
|
* Yikes, had to modify a bunch of stuff in key-list.cc to correctly
|
|
handle duplicate entries. Changed the generated code so that
|
|
the MIN_HASH_VALUE is no longer subtracted off when calculating
|
|
the hash value for a keyword. This required changing some other
|
|
code by substituting MAX_HASH_VALUE for TOTAL_KEYS in several places.
|
|
Finally, this means that the generated tables may contain leading
|
|
null entries, but I suppose it is better to trade-off space to get
|
|
faster performance...
|
|
|
|
Mon Mar 26 13:08:43 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Updated version number to 2.4 to reflect the latest changes.
|
|
|
|
* Changed the main program so that it always prints out gperf's
|
|
execution timings to the generated output file.
|
|
|
|
Sun Mar 25 12:39:30 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Added the -Z option so that users can specify the name of the
|
|
generated class explicitly. Updated documentation to reflect
|
|
this change.
|
|
|
|
* Modified the generated C++ class interface so that the functions
|
|
are declared static (to remove the overhead of passing the `this'
|
|
pointer). This means that operator()() can no longer be used,
|
|
since it only works on non-static member functions.
|
|
Also changed things so that there is no constructor (why waste
|
|
the extra call, when it doesn't do anything, eh?)
|
|
|
|
* Modified the behavior of Key_List::output when the -L C++ option
|
|
is enabled. Previously the code generated use const data members
|
|
to record MIN_WORD_LENGTH, MIN_HASH_VALUE, etc. However, as
|
|
pointed out by James Clark this may result in suboptimal behavior
|
|
on the part of C++ compilers that can't inline these values.
|
|
Therefore, the new behavior is identical to what happens with
|
|
-L C, i.e., either #defines or function-specific enums are used.
|
|
Why sacrifice speed for some abstract notion of `code purity?' ;-)

|
|
* Added the -E option that defines constant values using an enum
|
|
local to the lookup function rather than with #defines. This
|
|
also means that different lookup functions can reside in the
|
|
same file. Thanks to James Clark (jjc@ai.mit.edu).

|
|
|
|
* Added a special case to key_list::output_switch that doesn't
|
|
generate extra comparisons when the `-S' is given an argument
|
|
of 1 (the normal case). This should speed up the generated
|
|
code output a tad...

Fri Feb 23 14:21:28 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Renamed all instances of member function get_keysig_size
|
|
to get_max_keysig_size, since this is more precise...
|
|
|
|
* Changed all occurrences of charset to keysig (stands for ``key
|
|
signature'') to reflect the new naming convention used in the
|
|
USENIX paper.
|
|
|
|
Thu Feb 22 11:28:36 1990 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Changed the name of the generated associated values table from
|
|
asso_value to asso_values to reflect conventions in the USENIX
|
|
C++ paper.
|
|
|
|
Thu Feb 15 23:29:03 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Updated the gperf.texinfo file to fix some formatting problems
|
|
that had crept in since last time.
|
|
|
|
Wed Feb 14 23:27:24 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Fixed stupid bug in key-list.cc (get_special_input), wher
|
|
gperf replaced each '%' with the succeeding character.
|
|
|
|
* Added support for multiple target language generation. Currently
|
|
handled languages are C and C++, with C as the default. Updated
|
|
documentation and option handler to reflect the changes.
|
|
|
|
* Added a global destructor to new.cc and removed the #ifdef, since
|
|
the bloody thing now works with libg++.
|
|
|
|
Mon Feb 14 13:00:00 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Found out that my gperf paper was accepted at the upcoming
|
|
USENIX C++ Conference in San Francisco. Yow!
|
|
|
|
Tue Jan 30 09:00:29 1990 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* #ifdef'd out the new.cc memory allocator, since there are
|
|
problems with this and the libg++ stuff.
|
|
|
|
* Changed key-list.h so that class Vectors is a public (rather
|
|
than private) base class for class Key_List. The previous
|
|
form was illegal C++, but wasn't being caught by the old
|
|
g++ compiler. Should work now... ;-)
|
|
|
|
Sun Dec 10 14:08:23 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added several changes from rfg@ics.uci.edu. These changes
|
|
help to automate the build process.
|
|
|
|
Wed Nov 15 15:49:33 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Removed conditional compilation for GATHER_STATISTICS. There's
|
|
really no good reason to avoid collecting this info at run-time,
|
|
since that section of code is *hardly* the bottleneck... ;-)
|
|
|
|
* Simplified the C output routines in Key_List::set_output_types
|
|
and Key_List::output_keyword_table a bit in order to
|
|
speed-up and clean up the code generation.
|
|
|
|
* Modified function Key_List::get_special_input so that it does
|
|
not try to `delete' a buffer that turned out to be too short.
|
|
This is important since the new memory management scheme
|
|
does not handle deletions. However, adding a small amount of
|
|
garbage won't hurt anything, since we generally don't do this
|
|
operation more than a couple times *at most*!
|
|
|
|
* Created a new file (new.cc) which includes my own overloaded
|
|
operator new. This function should dramatically reduce the
|
|
number of calls to malloc since it grabs large chunks and
|
|
doles them out in small pieces. As a result of this change
|
|
the class-specific `operator new' was removed from class List_Node.
|
|
|
|
Tue Nov 14 21:45:30 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Continued to refine the great hack. The latest trick is to
|
|
try and replace most uses of dynamic memory (i.e., calls to
|
|
new) with uses of gcc dynamic arrays (i.e., an alloca solution).
|
|
This makes life much easier for the overall process-size, since
|
|
it reduces the amount of overhead for memory management. As a
|
|
side-effect from this change there is no reason to have the
|
|
Bool_Array::dispose member function, so it's outta here!
|
|
|
|
* Fixed a stupid bug that was an disaster waiting to happen...
|
|
Instead of making the boolean array large enough to index
|
|
max_hash_value it was only large enough to index max_hash_value
|
|
- 1. Once again, an off-by-one mistake in C/C++!!!!
|
|
|
|
Mon Nov 13 19:38:27 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added the final great hack! This allows us to generate hash tables
|
|
for near-perfect hash functions that contain duplicates, *without*
|
|
having to use switch statements! Since many compilers die on large
|
|
switch statements this feature is essential. Furthermore, it appears
|
|
that the generated code is often *smaller* than that put out by
|
|
compilers, even though a large, sparse array must be created.
|
|
Here's the general idea:
|
|
|
|
a. Generate the wordlist as a contiguous block of keywords,
|
|
just as before when using a switch statement. This
|
|
wordlist *must* be sorted by hash value.
|
|
|
|
b. Generate the lookup array, which is an array of signed
|
|
{chars,shorts,ints}, (which ever allows full coverage of
|
|
the wordlist dimensions). If the value v, where v =
|
|
lookup[hash(str,len)], is >= 0 and < TOTAL_KEYWORDS, then we
|
|
simply use this result as a direct access into the wordlist
|
|
array to snag the keyword for comparison.
|
|
|
|
c. Otherwise, if v is < -TOTAL_KEYWORDS or > TOTAL_KEYWORDS
|
|
this is an indication that we'll need to search through
|
|
some number of duplicates hash values. Using a hash
|
|
linking scheme we'd then index into a different part of
|
|
the hash table that provides the starting index and total
|
|
length of the duplicate entries to find via linear search!
|
|
|
|
Sun Nov 12 13:48:10 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Simplified Key_List::output_min_max considerably by recognizing
|
|
that since the keyword list was already sorted by hash value finding
|
|
the min and max values is trivial!
|
|
|
|
* Improved the debugging diagnostics considerably in classes Key_List,
|
|
Hash_Table, and Gen_Perf.
|
|
|
|
* Modified the `-s' option so that a negative argument is now
|
|
interpreted to mean `allow the maximum associated value to be
|
|
about x times *smaller* than the number of input keys.' This
|
|
should help prevent massive explosion of generated hash table
|
|
size for large keysets.
|
|
|
|
Sat Nov 11 11:31:13 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added a field in class Key_List that counts the total number
|
|
of duplicate keywords, both static and dynamic.
|
|
|
|
* Added a new member function Bool_Array that deletes the dynamic
|
|
memory allocated to Bool_Array::storage_array. This space may
|
|
be needed for subsequent options, so it made sense to free it as
|
|
soon as possible...
|
|
|
|
* Renamed file/class Alpha_Vectors to Vectors, to avoid problems
|
|
with 14 character length filenames on SYSV. Also changed file
|
|
adapredefined.gperf to adadefs.gperf in the ./tests directory.
|
|
|
|
* Modified class Options by changing the member function
|
|
Options::total_positions to Options::get_charset_size and
|
|
Options::set_charset_size. These two routines now either return
|
|
the total charset size *or* the length of the largest keyword
|
|
if the user specifies the -k'*' (ALLCHARS) option. This change
|
|
cleans up client code.
|
|
|
|
* Merged all the cperf changes into gperf.
|
|
|
|
* Made sure to explicitly initialize perfect.fewest_collisions to
|
|
0.
|
|
|
|
* Cleaned up some loose ends noticed by Nels Olson.
|
|
1. Removed `if (collisions <= perfect.fewest_collisions)'
|
|
from Gen_Perf::affects_prev since it was superfluous.
|
|
2. Removed the fields best_char_value and best_asso_value
|
|
from Gen_Perf. There were also unnecessary.
|
|
3. Fixed a braino in the Bool_Array::bool_array_reset
|
|
function. Since iteration numbers can never be zero
|
|
the `if (bool_array.iteration_number++ == 0)' must be
|
|
`if (++bool_array.iteration_number == 0).'
|
|
4. Modified Std_Err::report_error so that it correctly handles
|
|
"%%".
|
|
|
|
* It is important to note that -D no longer enables -S.
|
|
There is a good reason for this change, which will become
|
|
manifested in the next release... (suspense!).
|
|
|
|
* Made some subtle changes to Key_List::print_switch so that if finally
|
|
seems to work correctly. Needs more stress testing, however...
|
|
|
|
* Made a major change to the Key_List::print_switch function.
|
|
The user can now specify the number of switch statements to generate
|
|
via an argument to the -S option, i.e., -S1 means `generate 1
|
|
switch statement with all keywords in it,' -S2 means generate
|
|
2 switch statements with 1/2 the elements in each one, etc.
|
|
Hopefully this will fix the problem with C compilers not being
|
|
able to generate code for giant switch statements (but don't
|
|
hold your breath!)
|
|
|
|
* Changed Key_List::length function to Key_List::keyword_list_length.
|
|
|
|
* Added a feature to main.c that prints out the starting wall-clock
|
|
time before the program begins and prints out the ending wall-clock
|
|
time when the program is finished.
|
|
|
|
* Added the GATHER_STATISTICS code in hash-table.c so we can
|
|
keep track of how well double hashing is doing. Eventually,
|
|
GATHER_STATISTICS will be added so that all instrumentation
|
|
code can be conditionally compiled in.
|
|
|
|
* Fixed a stupid bug in Key_List::print_switch routine. This
|
|
was necessary to make sure the generated switch statement worked
|
|
correctly when *both* `natural,' i.e., static links and dynamic
|
|
links, i.e., unresolved duplicates, hash to the same value.
|
|
|
|
* Modified Bool_Array::~Bool_Array destructor so that
|
|
it now frees the bool_array.storage_array when it is no longer
|
|
needed. Since this array is generally very large it makes sense
|
|
to return the memory to the freelist when it is no longer in use.
|
|
|
|
* Changed the interface to constructor Hash_Table::Hash_Table. This
|
|
constructor now passed a pointer to a power-of-two sized buffer that
|
|
serve as storage for the hash table. Although this weakens information
|
|
hiding a little bit it greatly reduces dynamic memory fragmentation,
|
|
since we can now obtain the memory via a call to alloca, rather
|
|
than malloc. This change modified Key_List::read_keys calling
|
|
interface.
|
|
|
|
* Since alloca is now being used more aggressively a conditional
|
|
compilation section was added in main.c. Taken from GNU GCC,
|
|
this code gets rid of any avoidable limit on stack size so that
|
|
alloca does not fail. It is only used if the -DRLIMIT_STACK
|
|
symbol is defined when gperf is compiled.
|
|
|
|
* Added warnings in option.c so that user's would be informed
|
|
that -r superceeds -i on the command-line.
|
|
|
|
* Rewrote Gen_Perf::affects_prev. First, the code structure
|
|
was cleaned up considerably (removing the need for a dreaded
|
|
goto!). Secondly, a major change occurred so that Gen_Perf::affects_prev
|
|
returns FALSE (success) when fewest_hits gets down to whatever
|
|
it was after inserting the previous key (instead of waiting for
|
|
it to reach 0). In other words, it stops trying if it can
|
|
resolve the new collisions added by a key, even if there are
|
|
still other old, unresolved collisions. This modification was
|
|
suggested by Nels Olson and seems to *greatly* increase the
|
|
speed of gperf for large keyfiles. Thanks Nels!
|
|
|
|
* In a similar vein, inside the Gen_Perf::change routine
|
|
the variable `perfect.fewest_collisions is no longer initialized
|
|
with the length of the keyword list. Instead it starts out at
|
|
0 and is incremented by 1 every time change () is called.
|
|
The rationale for this behavior is that there are times when a
|
|
collision causes the number of duplicates (collisions) to
|
|
increase by a large amount when it would presumably just have
|
|
gone up by 1 if none of the asso_values were changed. That is,
|
|
at the beginning of change(), you could initialize fewest_hits
|
|
to 1+(previous value of fewest_hits) instead of to the number of
|
|
keys. Thanks again, Nels.
|
|
|
|
* Replaced alloca with new in the Gen_Perf::change function.
|
|
This should eliminate some overhead at the expense of a little
|
|
extra memory that is never reclaimed.
|
|
|
|
* Renamed Gen_Perf::merge_sets to Gen_Perf::compute_disjoint_union
|
|
to reflect the change in behavior.
|
|
|
|
* Added the -e option so users can supply a string containing
|
|
the characters used to separate keywords from their attributes.
|
|
The default behavior is ",\n".
|
|
|
|
* Removed the char *uniq_set field from LIST_NODE and modified
|
|
uses of uniq_set in perfect.c and keylist.c. Due to changes
|
|
to Gen_Perf::compute_disjoint_sets this field was no longer
|
|
necessary, and its removal makes the program smaller and
|
|
potentially faster.
|
|
|
|
* Added lots of changes/fixes suggested by Nels Olson
|
|
(umls.UUCP!olson@mis.ucsf.edu). In particular:
|
|
1. Changed Bool_Array so that it would dynamically create
|
|
an array of unsigned shorts rather than ints if the
|
|
LO_CAL symbol was defined during program compilation.
|
|
This cuts the amount of dynamic memory usage in half,
|
|
which is important for large keyfile input.
|
|
2. Added some additional debugging statements that print extra
|
|
info to stderr when the -d option is enabled.
|
|
3. Fixed a really stupid bug in Key_List::print_switch
|
|
A right paren was placed at the wrong location, which broke
|
|
strlen ().
|
|
4. Fixed a subtle problem with printing case values when keylinks
|
|
appear. The logic failed to account for the fact that there
|
|
can be keylinks *and* regular node info also!
|
|
5. Changed the behavior of Key_List::read_keys so that it would
|
|
honor -D unequivocally, i.e., it doesn't try to turn off dup
|
|
handling if the user requests it, even if there are no
|
|
immediate links in the keyfile input.
|
|
6. Modified the -j option so that -j 0 means `try random values
|
|
when searching for a way to resolve collisions.'
|
|
7. Added a field `num_done' to the Gen_Perf struct. This is used
|
|
to report information collected when trying to resolve
|
|
hash collisions.
|
|
8. Modified the merge_sets algorithm to perform a disjoint
|
|
union of two multisets. This ensures that subsequent
|
|
processing in Gen_Perf::affect_prev doesn't
|
|
waste time trying to change an associated value that is
|
|
shared between two conflicting keywords.
|
|
9. Modified Gen_Perf::affects_prev so that it doesn't try
|
|
random jump values unless the -j 0 option is enabled.
|
|
10. Fixed a silly bug in Gen_Perf::change. This problem caused
|
|
gperf to seg fault when the -k* option was given and the
|
|
keyfile file had long keywords.
|
|
|
|
Sun Oct 29 00:18:55 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
|
|
|
* Modified class-specific new operations for Read_Line and
|
|
List_Node so they don't fail if SIZE is larger than twice
|
|
the previous buffer size. Note we double buffer size
|
|
everytime the previous buffer runs out, as a heuristic
|
|
to reduce future calls to malloc.
|
|
|
|
Sun Oct 22 13:49:43 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Updated gperf version number to 2.0. Send to Doug Lea for
|
|
incorporation into the long-awaited `official' libg++ 1.36
|
|
release!
|
|
|
|
* Thanks to Nels Olson a silly bug in Gen_Perf::change ()
|
|
was fixed. This problem caused gperf to seg fault when
|
|
the -k* option was given and the keyfile file had long
|
|
keywords.
|
|
|
|
* Modified Key_List::print_hash_function so that it output
|
|
max_hash_value + 1 (rather than just max_hash_value) for
|
|
any associated value entries that don't correspond to
|
|
keyword charset characters. This should speed up rejection
|
|
of non-keyword strings a little in some cases.
|
|
|
|
Sat Oct 21 19:28:36 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Fixed Key_List::print_hash_function so that it no longer output
|
|
things like `return 0 + ...' Although this probably gets
|
|
optimized away by even the worst C compilers there isn't any
|
|
point tempting fate... ;-)
|
|
|
|
* Fixed class List_Node's constructor so that it wouldn't a priori
|
|
refuse to consider trying to hash keys whose length is less
|
|
than the smallest user-specified key position. It turns out
|
|
this is not a problem unless the user also specifies the -n
|
|
(NOLENGTH) option, in which case such keys most likely
|
|
don't have a prayer of being hashed correctly!
|
|
|
|
* Changed the name of the generated lookup table from `Hash_Table'
|
|
to `asso_value' to be consistent with the gperf paper.
|
|
|
|
Tue Oct 17 14:19:48 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added a flag GATHER_STATISTICS in the Makefile. If defined
|
|
during compilation this turns on certain collection facilities
|
|
that track the performance of gperf during its execution. In
|
|
particular, I want to see how many collisions occur for the
|
|
double hashing Hash_Table.
|
|
|
|
* Added a safety check so that we don't screw up if the total
|
|
number of `resets' of the Bool_Array exceeds MAX_INT. Since
|
|
this number is around 2^31 it is unlikely that this would ever
|
|
occur for most input, but why take the risk?
|
|
|
|
* Changed the behavior for the -a (ANSI) option so that the
|
|
generated prototypes use int rather than size_t for the LEN
|
|
parameter. It was too ugly having to #include <stddef.h> all
|
|
over the place...
|
|
|
|
Mon Oct 16 11:00:35 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Continued to work on the gperf paper for the USENIX C++
|
|
conference. At some point this will be merged back into
|
|
the gperf documentation...
|
|
|
|
Sat Oct 14 20:29:43 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
|
|
|
* Added a majorly neat hack to Bool_Array, suggested by rfg.
|
|
The basic idea was to throw away the Ullman array technique.
|
|
The Ullman array was used to remove the need to reinitialize all
|
|
the Bool_Array elements to zero everytime we needed to determine
|
|
whether there were duplicate hash values in the keyword list.
|
|
The current trick uses an `iteration number' scheme, which takes
|
|
about 1/3 the space and reduces the overall program running a
|
|
time by about 20 percent for large input! The hack works as
|
|
follows:
|
|
|
|
1. Dynamically allocation 1 boolean array of size k.
|
|
2. Initialize the boolean array to zeros, and consider the first
|
|
iteration to be iteration 1.
|
|
2. Then on all subsequent iterations we `reset' the bool array by
|
|
kicking the iteration count by 1.
|
|
3. When it comes time to check whether a hash value is currently
|
|
in the boolean array we simply check its index location. If
|
|
the value stored there is *not* equal to the current iteration
|
|
number then the item is clearly *not* in the set. In that
|
|
case we assign the iteration number to that array's index
|
|
location for future reference. Otherwise, if the item at
|
|
the index location *is* equal to the iteration number we've
|
|
found a duplicate. No muss, no fuss!
|
|
|
|
Mon Oct 2 12:30:54 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Changed some consts in options.h to enumerals, since g++
|
|
doesn't seem to like them at the moment!
|
|
|
|
Sat Sep 30 12:55:24 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Fixed a stupid bug in Key_List::print_hash_function that manifested
|
|
itself if the `-k$' option was given (i.e., only use the key[length]
|
|
character in the hash function).
|
|
|
|
* Added support for the -C option. This makes the contents of
|
|
all generated tables `readonly'.
|
|
|
|
* Changed the handling of generated switches so that there is
|
|
only one call to str[n]?cmp. This *greatly* reduces the size of
|
|
the generated assembly code on all compilers I've seen.
|
|
|
|
* Fixed a subtle bug that occurred when the -l and -S option
|
|
was given. Code produced looked something like:
|
|
|
|
if (len != key_len || !strcmp (s1, resword->name)) return resword;
|
|
|
|
which doesn't make any sense. Clearly, this should be:
|
|
|
|
if (len == key_len && !strcmp (s1, resword->name)) return resword;
|
|
|
|
Tue Sep 26 10:36:50 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Changed class Read_Line's definition so that it no longer
|
|
needs to know about the buffering scheme used to speed up
|
|
dynamic memory allocation of input keywords and their
|
|
associated attributes. This means that operator new is no longer
|
|
a friend of Read_Line.
|
|
|
|
Mon Sep 25 23:17:10 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Decided that Obstacks had too much overhead, so they were
|
|
removed in favor of super-efficient, low-overhead buffered
|
|
storage allocation hacks in Read_Line and List_Node.
|
|
|
|
* No longer try to inline functions that g++ complains about
|
|
(Key_List::Merge and Key_List::Merge_Sort).
|
|
|
|
Sun Sep 24 13:11:24 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Changed classes Read_Line and List_Node to use Obstacks in order
|
|
to cache memory allocation for keyword strings and List_Nodes.
|
|
|
|
* Continued to experiment with inheritance schemes.
|
|
|
|
* Added a new file `alpha.h', that declares static data shared
|
|
(i.e., inherited) between classes List_Node and Key_List.
|
|
|
|
Tue Sep 12 16:14:41 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Made numerous changes to incorporate multiple inheritance in
|
|
gperf.
|
|
|
|
Wed Aug 16 23:04:08 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added the -DCOMPILER_FIXED flag to the ./src/Makefile. This
|
|
implies that people trying to compile gperf need to have a
|
|
working version of the new g++ compiler (1.36.0).
|
|
|
|
* Removed some extra spaces that were being added in the generated
|
|
C code.
|
|
|
|
Mon Jul 24 17:09:46 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Fixed PRINT_HASH_FUNCTION and PRINT_LOOKUP_FUNCTION in keylist.c
|
|
so that the generated functions take an unsigned int length argument.
|
|
If -a is enabled the prototype is (const char *str, size_t len).
|
|
|
|
Fri Jul 21 13:06:15 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Fixed a typo in PRINT_KEYWORD_TABLE in keylist.cc that prevented
|
|
the indentation from working correctly.
|
|
|
|
* Fixed a horrible typo in PRINT_KEYWORD_TABLE in keylist.cc
|
|
that prevented links from being printed correctly.
|
|
|
|
Tue Jul 18 16:04:31 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Fixed up readline.cc and readline.h so that they work OK
|
|
with g++ compilers that aren't completely up-to-date.
|
|
If symbol COMPILER_FIXED is defined then the behavior
|
|
that works on my more recent version of g++ is enabled.
|
|
|
|
Sun Jul 9 17:53:28 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Changed the ./tests subdirectory Makefile so that it
|
|
uses $(CC) instead of gcc.
|
|
|
|
Sun Jul 2 21:52:15 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Fixed a number of subtle bugs that occurred when -S was
|
|
combined with various and sundry options.
|
|
|
|
* Added the -G option, that makes the generated keyword table
|
|
a global static variable, rather than hiding it inside
|
|
the lookup function. This allows other functions to directly
|
|
access the contents in this table.
|
|
|
|
* Added the "#" feature, that allows comments inside the keyword
|
|
list from the input file. Comment handling takes place in readline.c.
|
|
This simplifies the code and reduces the number of malloc calls.
|
|
|
|
* Also added the -H option (user can give the name of the hash
|
|
function) and the -T option (prevents the transfer of the type decl
|
|
to the output file, which is useful if the type is already defined
|
|
elsewhere).
|
|
|
|
Thu Jun 22 20:39:39 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Modified many classes so that they would inherit Std_Err as
|
|
a base class. This makes things more abstract...
|
|
|
|
Fri Jun 16 14:23:00 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Modified the -f (FAST) option. This now takes an argument.
|
|
The argument corresponds to the number of iterations used
|
|
to resolve collisions. -f 0 uses the length of the
|
|
keyword list (which is what -f did before). This makes
|
|
life much easier when dealing with large keyword files.
|
|
|
|
Tue Jun 6 17:53:27 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added the -c (comparison) option. Enabling this
|
|
will use the strncmp function for string comparisons.
|
|
The default is to use strcmp.
|
|
|
|
* Fixed a typo in key_list.cc (PRINT_SWITCH). This caused
|
|
faulty C code to be generated when the -D, -p, and -t
|
|
options were all enabled.
|
|
|
|
Thu May 25 14:07:21 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
|
|
|
* Once again, changed class Read_Line to overload global operator
|
|
new. Hopefully, this will work...!
|
|
|
|
Sun May 21 01:51:45 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Modified Key_List::print_hash_function () so that it properly
|
|
formats the associated values in the hash table according to
|
|
the maximum number of digits required to represent the largest
|
|
value.
|
|
|
|
* Removed the named return value from class Hash_Table's
|
|
operator (), since this causes a seg fault when -O is enabled.
|
|
No sense tripping subtle g++ bugs if we don't have to.... ;-)
|
|
|
|
* Removed the operator new hack from Read_Line, since this seemed
|
|
to create horrible bus error problems.
|
|
|
|
* Changed many class member functions and data members to be `static',
|
|
if they don't manipulate this!
|
|
|
|
Fri May 12 23:06:56 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Changed class Std_Err to use static member functions, a la
|
|
Ada or Modula 2. This eliminates the need for an explicit
|
|
error-handler class object.
|
|
|
|
* Added the ``named return value'' feature to Hash_Table::operator ()
|
|
and Bool_Array::operator [], just for the heck of it.... ;-)
|
|
|
|
* Changed the previous hack in Read_Line so that we now use
|
|
the overloaded global `new' instead of NEW_STRING!
|
|
|
|
Wed May 3 17:36:55 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Updated to version 1.7. This reflects the recent major changes
|
|
and the new C port.
|
|
|
|
* Modified the GNU getopt.cc routine to have a class-based interface.
|
|
|
|
* Fixed a typo in Perfect.cc ~Perfect that prevented the actual maximum
|
|
hash table size from being printed (maybe the stream classes
|
|
weren't so bad after all.... ;-).
|
|
|
|
* Added support for the -f option. This generates the perfect
|
|
hash function ``fast.'' It reduces the execution time of
|
|
gperf, at the cost of minimizing the range of hash values.
|
|
|
|
Tue May 2 16:23:29 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Added an efficiency hack to Read_Line. Instead of making
|
|
a call to operator NEW (a.k.a. malloc) for each input string
|
|
a new member function NEW_STRING stores a large buffer from
|
|
which new strings are carved out, growing the buffer if
|
|
necessary. It might be useful to add this throughout the
|
|
program....
|
|
|
|
* Removed all unnecessary calls to DELETE. If the program is about
|
|
to exit it is silly to waste time freeing memory.
|
|
|
|
* Added the GNU getopt program to the distribution. This makes
|
|
GPERF portable to systems that don't include getopt in libc.
|
|
|
|
* Added a strcspn member to class Key_List. This also increases
|
|
portability.
|
|
|
|
* Added the get_include_src function from keylist.c as a member
|
|
function in class Key_List. Hopefully every function is
|
|
now associated with a class. This aids abstraction and
|
|
modularity.
|
|
|
|
* Ported gperf to C. From now on both K&R C and GNU G++ versions
|
|
will be supported. There will be two ChangeLog files, one
|
|
for each version of the program.
|
|
|
|
Mon May 1 16:41:45 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Fixed a bug with -k'*'. This now prints out *all* the cases
|
|
up to the length of the longest word in the keyword set.
|
|
|
|
Sun Apr 30 12:15:25 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Removed all use of the stream classes. Too ugly, slow, and
|
|
not handled by the c++-mode formatter....
|
|
|
|
* Modified the handling of links (i.e., keywords that have
|
|
identical hash values as other keywords). This should
|
|
speed up hash function generation for keyword sets with
|
|
many duplicate entries. The trick is to treat duplicate
|
|
values as equivalence classes, so that each set of duplicate
|
|
values is represented only once in the main list processing.
|
|
|
|
* Fixed some capitialization typos and indentations mistakes in
|
|
Key_List::print_hash_function.
|
|
|
|
Sat Apr 29 12:04:03 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Fixed a typo/logico in Key_List::print_switch that prevented
|
|
the last keyword in the keyword list to be print out. This
|
|
requires further examination.....
|
|
|
|
* Fixed a stupid bug in List_Node::List_node. If the -k'*' option
|
|
was enabled the KEY_SET string wasn't getting terminated with
|
|
'\0'!
|
|
|
|
Fri Apr 28 12:38:35 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Renamed strexp.h and strexp.cc to iterator.h and iterator.cc.
|
|
Also changed the strexp class to iterator. Continued to work
|
|
on style...
|
|
|
|
* Updated the version number to 1.6. This reflects all the
|
|
recent changes.
|
|
|
|
Thu Apr 27 00:14:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added the -D option that properly handles keyword sets that
|
|
contain duplicate hash values.
|
|
|
|
* Continued the stylistic changes. Added the #pragma once
|
|
directive to all the *.h files. Removed all #defines and
|
|
replaced them with static consts. Also moved the key_sort
|
|
routine from options.cc into the options class as a
|
|
member function.
|
|
|
|
Mon Apr 3 13:26:55 1989 Doug Schmidt (schmidt at zola.ics.uci.edu)
|
|
|
|
* Made massive stylistic changes to bring source code into
|
|
conformance with GNU style guidelines.
|
|
|
|
Thu Mar 30 23:28:45 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Fixed up the output routines so that they generate code
|
|
corresponding to the GNU style guidelines.
|
|
|
|
Sat Mar 11 13:12:37 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Fixed Stderr constructors so that they wouldn't try to
|
|
use the base class initializer syntax for the static
|
|
class variable Program_Name. G++ 1.34 is stricter in
|
|
enforcing the rules!
|
|
|
|
Fri Mar 10 11:24:14 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Removed -v and ``| more'' from the Makefile to keep rfg happy...
|
|
|
|
Thu Mar 2 12:37:30 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Sent latest GNU gperf version 1.5 to Doug Lea for inclusion
|
|
into libg++ 1.34. Note that there is a small bug with
|
|
the new %{ ... %} source inclusion facility, since it doesn't
|
|
understand comments and will barf if %{ or %} appear nested
|
|
inside the outermost delimiters. This is too trivial of
|
|
a defect to fix at the moment...
|
|
|
|
Tue Feb 28 11:19:58 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added the -K option, which allows the user to provide a
|
|
alternative name for the keyword structure component.
|
|
The default is still ``name.''
|
|
|
|
* Added the LEX and YACC-like ability to include arbitrary
|
|
text at the beginning of the generated C source code output.
|
|
This required two new functions Get_Special_Input,
|
|
Key_List::Save_Include_Src;
|
|
|
|
* Fixed memory allocation bug in Key_List::Set_Types.
|
|
Variable Return_Type needs 1 additional location
|
|
to store the "*" if the -p option is used.
|
|
|
|
* Added code to NULL terminate both Struct_Tag and Return_Type,
|
|
*after* the strncpy (stupid mistake).
|
|
|
|
Mon Feb 27 14:39:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added a new option -N. This allows the user to specify the
|
|
name to be used for the generated lookup function. The
|
|
default name is still ``in_word_set.'' This makes it
|
|
possible to completely automate the perfect hash function
|
|
generation process!
|
|
|
|
Mon Feb 20 23:33:14 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Corrected the Hash_Table::operator () function so that
|
|
*it* is responsible for deciding when a new key has the
|
|
same signature as a previously seen key. The key length
|
|
information is now used internally to this function to
|
|
decide whether to add to the hash table those keys with
|
|
the same key sets, but different lengths. Before, this
|
|
was handled by the Key_List::Read_Keys function. However,
|
|
this failed to work for certain duplicate keys, since
|
|
they weren't being entered into the hash table properly.
|
|
|
|
Sun Feb 19 16:02:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Modified class Options by moving the enum Option_Type out
|
|
of the class. This is to satisfy the new enumeration
|
|
scope rules in C++.
|
|
|
|
Sun Jan 15 15:12:09 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Incremented the version number upto 1.4 to reflect the new
|
|
options that affect the generated code. Send the new
|
|
distribution off to Michael for use with g++ 1.33.
|
|
|
|
* Added a fix to Key_List::Read_Keys so that it checks for links
|
|
properly when the -n option is used. Previously, it didn't
|
|
catch obvious links, which caused it to spend large amount
|
|
of time searching for a solution that could never occur!
|
|
|
|
* Modified the Key_List data structure to record *both* the
|
|
minimum and the maximum key lengths. This information
|
|
is now computed in Key_List::Read_Keys, and thus
|
|
Key_List::Print_Min_Max doesn't need to bother.
|
|
|
|
* Modifed the key position iterator scheme in options.cc to
|
|
eliminate the need for member function Options::Advance.
|
|
Now, the Options::Get function performs the advancement
|
|
automatically, obviating the need for an extra function call.
|
|
|
|
* Added the new function Options::Print_Options, to print out
|
|
the user-specified command line options to generated C
|
|
output file.
|
|
|
|
* Added a new function, Key_List::Print_Keylength_Table,
|
|
which creates a table of lengths for use in speeding
|
|
up the keyword search. This also meant that a new
|
|
option, -l (LENTABLE) is recognized. It controls
|
|
whether the length table is printed and the comparison
|
|
made in the generated function ``in_word_set.''
|
|
|
|
* Added a comment at the top of the generated C code
|
|
output file that tells what version of gperf was used.
|
|
Next, I'll also dump out the command line options
|
|
as a comment too. Thanks to Michael Tiemann for the
|
|
feedback on this.
|
|
|
|
* Fixed the -n option to make it work correctly with
|
|
other parts of the program (most notably the Perfect::Hash
|
|
function and the computation of minimum and maximum lengths.
|
|
|
|
Fri Jan 13 21:25:27 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
|
|
|
* Realized the the need to add a test that will enable
|
|
optimziation of the generated C code in the ``hash'' function
|
|
by checking whether all the requested key positions are
|
|
guaranteed to exist due to the comparison in `in_word_set.''
|
|
I'll put this in soon....
|
|
|
|
Thu Jan 12 20:09:21 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Added pascal, modula3, and modula2 tests inputs to the
|
|
Makefile
|
|
|
|
* Recognised that there is a bug with the -n option. However
|
|
I'm too busy to fix it properly, right now. The problem
|
|
is that the generated #define end up being 0, since that's
|
|
my hack to make -n work. This needs complete rethinking!
|
|
|
|
Tue Jan 10 00:08:16 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Added a new option, -n, that instructs gperf to not use the
|
|
length of an identifier when computing the hash functions.
|
|
I'm not sure how useful this is!
|
|
|
|
* Retransmitted the distribution to rocky.oswego.edu. Hopefully,
|
|
this will work!
|
|
|
|
* Began fixing the indentation and capitalization to conform
|
|
to the GNU coding guidelines.
|
|
|
|
Mon Jan 9 22:23:18 1989 Doug Schmidt (schmidt at pompe.ics.uci.edu)
|
|
|
|
* Fixed horrible bug in Read_Line::Readln_Aux. This was
|
|
a subtle and pernicous off-by-1 error, that overwrote
|
|
past the last character of the input string buffer. I
|
|
think this fault was killing the vax!
|
|
|
|
* Yow, fixed an oversight in List_Node::List_Node, where the
|
|
pointer field Next was uninitialized. Luckily, the new routine
|
|
seems to return 0 filled objects the first time through!
|
|
|
|
Sun Jan 8 13:43:14 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Modified the ``key linked'' diagnostic in Key_List::Read_Keys
|
|
to be more helpful and easy to read.
|
|
|
|
* Fixed the List_Node::List_Node so that it would ignore trailing
|
|
fields if the -t option was not enabled.
|
|
|
|
* Moved the List_Node declarations out of keylist.h and
|
|
into a file of its own, called listnode.cc and listnode.h
|
|
Made Set_Sort a member function of class List_Node.
|
|
|
|
* Massively updated the documentation in the gperf.texinfo file.
|
|
|
|
* Polished off the major revision to the print functions,
|
|
added a few new tests in the Makefile to check for the
|
|
validity of the program and ftp'ed the entire distribution
|
|
off to Doug Lea for libg++. ( changed it to
|
|
1.3 to reflect the major changes with the generated
|
|
C code ).
|
|
|
|
* Fixed Key_List::Print_Switch to deal with the -p and -t options.
|
|
This meant that the ``still-born'' function Key_List::
|
|
Print_Type_Switch was superflous, so I removed it.
|
|
Also, removed the restriction in Option that the -p and
|
|
-t options couldn't be used simultaneously.
|
|
|
|
* Modified List_Node::List_Node, to perform only 1 call to
|
|
``new'' when dynamically allocating memory for the Key_Set
|
|
and the Uniq_Set.
|
|
|
|
Sat Jan 7 14:10:51 1989 Doug Schmidt (schmidt at glacier.ics.uci.edu)
|
|
|
|
* Fixed a big bug with the new policy of nesting the
|
|
wordlist inside of generated function ``in_word_set.''
|
|
I'd forgotten to declare the wordlist array as static!
|
|
( arrgh ).
|
|
|
|
* Added a new function Key_List::Set_Types, that figures out
|
|
the return type for generated function ``in_word_set,''
|
|
the user-defined ``struct tag,'' if one is used, and also
|
|
formates the array type for the static local array.
|
|
|
|
* Changed the print routines to take advantage of the
|
|
new -p option.
|
|
|
|
* Began adding the hooks to allow the return of a pointer
|
|
to a user defined struct location from the generated
|
|
``in_word_set'' function instead of the current 0 or 1
|
|
return value. Created function Key_List::Print_Type_Switch
|
|
and added option -p to class Option, allowing the user to
|
|
request generation of the aforementioned pointers returned
|
|
instead of booleans.
|
|
|
|
* Put in checks in class Option to make sure that -S and -t
|
|
options are not used simultaneously. This restriction
|
|
will be removed in subsequent releases, once I decide on
|
|
a clean way to implement it.
|
|
|
|
* Sent version 1.2 to Doug Lea for possible inclusion into
|
|
the libg++ distribution.
|
|
|
|
* Moved the static word_list array inside the generated function
|
|
in_word_set. This supports better data hiding.
|
|
|
|
* Added a texinfo file, gperf.texinfo
|
|
|
|
* Revised the Makefile to cleanup the droppings from texinfo
|
|
and changed the name of gperf.cc and gperf.h to perfect.cc
|
|
and perfect.h.
|
|
|
|
Fri Jan 6 13:04:45 1989 Doug Schmidt (schmidt at crimee.ics.uci.edu)
|
|
|
|
* Implemented the switch statement output format. Much better
|
|
for large datasets in terms of space used.
|
|
|
|
* Added new functions to break up the Key_List::Output function.
|
|
Functions added were Key_List::Print_Switch, Key_List::Print_Min_Max,
|
|
Key_List::Print_Keyword_Table, Key_List::Print_Hash_Function,
|
|
and Key_List::Print_Lookup_Function. This simplifies the
|
|
big mess in Key_List::Output considerably!
|
|
|
|
* Added switch statement option to Options, which potentially
|
|
trades time for space in the generated lookup code.
|
|
|
|
Thu Jan 5 22:46:34 1989 Doug Schmidt (schmidt at siam.ics.uci.edu)
|
|
|
|
* Released version 1.1

* Fixed a bug with Gperf::Merge_Set, it was skipping letters shared
|
|
between the Set_1 and Set_2.
|
|
|
|
* Added the optimal min/max algorithm in Key_List::Output. This
|
|
runs in O ( 3n/2 ), rather than O ( 2n ) time.
|
|
|
|
* Changed Gperf::Sort_Set to use insertion sort, rather than
|
|
bubble sort.
|
|
|
|
* Added a check in Key_List::Output for the special case where
|
|
the keys used are 1,$. It is possible to generate more
|
|
efficient C code in this case.
