2010/11/26 simplification of output.c using putc_code() and putl_code()
|

omitted an adjustment of the #line value used for code-file. Fix that.

Also, amend 2005/05/04 change to run_test.sh to retain a dummy line for
|

YYPATCH #define's to make test-outputs easier to compare #line's (report

* reader.c: fix for valgrind
|
||||
(the calloc's are intentional - valgrind reported use of uninitialized memory)
|
||||
|

* lr0.c, output.c: fix for valgrind

* test/btyacc/code_debug.c, test/btyacc/code_debug.error, test/btyacc/code_debug.h, test/btyacc/code_debug.i, test/btyacc/code_debug.output:

* mstring.c: ifdef'd functions not used in byacc
|

* btyaccpar.c: generated from btyaccpar.skel
|
||||
|
||||
* yaccpar.c: generated from yaccpar.skel
|
||||
|
||||
* skel2c:
|
||||
change the generated-by comment to show which version of this script (and
|
||||
which version of the given skeleton file) were used to produce the C-file.
|
||||
|
||||
* configure: regen
|
||||
|
||||
* makefile.in:
|
||||
add rules to generate byacc and btyacc parser skeleton files independently
|
||||
|
||||
* aclocal.m4: CF_PROG_AWK - add to byacc's configure script
|
||||
CF_INTEL_COMPILER
|
||||
cleanup the -no-gcc option which was leftover from testing - prcs does
|
||||
not build with this option.
|
||||
CF_MAKE_DOCS
|
||||
protect $2 from substitution, for luit's "$(manext)"
|
||||
CF_XOPEN_SOURCE
|
||||
for Solaris (tested with gcc/g++ 3.4.3 on Solaris 10 and gcc/g++ 4.5.2
|
||||
on Solaris 11), suppress the followup check for defining _XOPEN_SOURCE
|
||||
because it is not needed, as well as because g++ 4.7.3 (no package,
|
||||
used in Sage for Solaris 10) has some unspecified header breakage which
|
||||
is triggered by the duplicate definition.
|
||||
|
||||
* configure.in:
|
||||
modify so skeleton-source is determined by configure options rather than by
|
||||
having developer rename yaccpar.skel.old to yaccpar.skel
|
||||
|
||||
* descrip.mms: rename skeleton
|
||||
|
||||
* vmsbuild.com:
|
||||
fwiw, renamed the skeleton for consistency with makefile
|
||||
|
||||
* skel2c, skeleton.c: resync skeleton and its generating files
|
||||

PARKING LOT ISSUES:
|
||||
-------------------
|
||||
- verify debian packaging still works?
|
||||
|
||||
- there are no #line directives in y.tab.i, other than those that come
|
||||
from the input file and the skeleton file; to fix this, would need to
|
||||
count output lines in externs_file and add 'write_externs_lineno()'
|
||||
similar to 'write_code_lineno()'
|
||||
- if there are no defined symbols, the .tab.h file isn't empty (weird case,
|
||||
may not be worth fixing)
|
||||
- consider: treat []-actions identical to {}-actions if not processing a
|
||||
backtracking parser (avoids test case error)?
|
||||
|
||||
|
||||
BTYACC CHANGES CURRENTLY DEFERRED, BY FILE:
|
||||
-------------------------------------------
|
||||
|
||||
push.skel
|
||||
- skeleton for a 'push' parser
|
||||
- needs to be upgraded match the structure of yaccpar.skel
|
||||
|
||||
defs.h
|
||||
- adopt '%include' changes
|
||||
- adopt '%define'/'%ifdef'/'%endif'
|
||||
- adopt -E flag to print preprocessed grammar to stdout
|
||||
|
||||
error.c
|
||||
- adopt '%include' changes
|
||||
- NOTE: there is a btyacc change that might be worth adopting in byacc
|
||||
[FileError() refactoring to eliminate duplicated code in most of the
|
||||
error message functions]
|
||||
|
||||
main.c
|
||||
- adopt '%define' changes
|
||||
- adopt '-DNAME' command line option to define preprocessor variable NAME
|
||||
- adopt -E flag to print preprocessed grammar to stdout
|
||||
- adopt '-S skeleton_file' command line option to select an alternate parser
|
||||
skeleton file
|
||||
- the skeleton file named by the -S flag is used as provided to open the
|
||||
file; consider a change to this behavior to check whether the named file
|
||||
has a path prefix, and if not, look in 'installation' directory if the
|
||||
file is not found in the working directory
|
||||
|
||||
output.c
|
||||
- adopt '%include' changes
|
||||
|
||||
reader.c
|
||||
- adopt '%include' changes
|
||||
- adopt '%define'/'%ifdef'/'%endif' changes
|
||||
- adopt -E flag to print preprocessed grammar to stdout
|
||||
- NOTE: there is a btyacc change that might be worth adopting in byacc
|
||||
[copy_string() & copy_comment() refactoring to eliminate duplicated
|
||||
code in copy_text() and copy_union()]
|
||||
|
||||
warshall.c
|
||||
- NOTE: there is a btyacc change that might be worth adopting in byacc
|
||||
[shifting 'mask' incrementally rather than literal '1' by a variable
|
||||
amount each time thru the loop]
|
||||
|
||||
|
||||
================================================================================
|
||||
|
||||
|
||||
new files:
|
||||
----------
|
||||
|
||||
skel2c
|
||||
- modified from btyacc distribution: don't generate #include defs.h
|
||||
- extended syntax recognized to include '%% insert VERSION here', generating
|
||||
the defines for YYMAJOR, YYMINOR and YYPATCH at that point
|
||||
- made generated tables type 'const char *const' to match skelton.c from
|
||||
byacc-20130925 baseline
|
||||
- added code to append text for write_section() to end of generated skeleton.c
|
||||
- remove conversion of tab to \t in generated skeleton.c
|
||||
- extended syntax recognized to include '%%ifdef', '%%ifndef', '%%else' and
|
||||
'%%endif'; used in yaccpar.skel to bracket code that is specific to
|
||||
backtracking
|
||||
|
||||
yaccpar.skel.old
|
||||
- created from skeleton.c in byacc-20140101 baseline; use of this skeleton
|
||||
will create a version of skeleton.c that is close to that in the
|
||||
byacc-20140101 baseline
|
||||
- eliminated 'body_3' and 'trailer_2' skeleton segments - no need to generate
|
||||
yyerror() invocation dynamically; YYERROR_CALL() is already generated
|
||||
earlier, and so can be used in the skeleton to simplify
|
||||
- added 'const' to types in '%% tables' section to match what skel2c,
|
||||
start_int_table() and state_str_table() generate
|
||||
- added a few cosmetic changes (e.g., added some additional comments,
|
||||
reworded debugging output to match yaccpar.skel, changed yygrowstack()
|
||||
to return YYENOMEM for 'out of memory' error, rather than -1, to match
|
||||
yaccpar.skel; changed yyparse() return value from 1 to 2 for the
|
||||
'out of memory' error to match yaccpar.skel)
|
||||
- added '#ifndef'/'#endif' around '#define YYINITSTACKSIZE 200' to allow
|
||||
the value to be changed at compile time
|
||||
- changed 'printf(' to 'fprintf(stderr, '; added stack depth (yydepth) to
|
||||
debugging output from yaccpar.skel
|
||||
- use 'YYINT' rather than 'short' for integer table types
|
||||
|
||||
yaccpar.skel
|
||||
- renamed from btyaccpa.ske, merged with btyacc-c.ske
|
||||
- modified from btyacc distribution to match the latest byacc-20140101
|
||||
skeleton structure & data structures
|
||||
- make local functions static
|
||||
- change "virtual memory exceeded" to "memory exhausted" for bison
|
||||
compatibility
|
||||
- change debug output generation from printf/puts/putc onto stdout to use
|
||||
fprintf/fputs/fputc onto stderr; include
|
||||
stack depth and whether or not in trial parsing
|
||||
- changed types of generated string tables to be 'const pointer to const char'
|
||||
- check all malloc()/realloc() return values, ensure return value of
|
||||
yyparse() = 2 if parsing failed due to memory exhaustion
|
||||
- change YYDBPR() macro to YYSTYPE_TOSTRING(); define semantics as delivering
|
||||
a char* value representing a semantic value (e.g., yylval or yyval, or the
|
||||
contents of an entry on the semantic stack); additional parameter passed:
|
||||
grammar symbol # (to assist interpretation of semantic value)
|
||||
- change YYPOSN to YYLTYPE and yyposn to yylloc (position corresponding to
|
||||
yylval) for bison compatibility; add yyloc (corresponding to yyval)
|
||||
- move default definition of YYLTYPE into output.c, generating a typedef
|
||||
- add '#if defined(YYLTYPE) || defined(YYLTYPE_IS_DECLARED)'/'#endif' around
|
||||
all lines specific to position processing
|
||||
- add '#if defined(YYDESTRUCT_CALL)'/'#endif' around all lines specific to
|
||||
semantic & position stack processing to reclaim memory associated with
|
||||
discarded symbols
|
||||
- add '%%ifdef YYBTYACC'/'%%endif' around all lines specific to backtrack
|
||||
parsing; converted by skel2c into '#if defined(YYBTYACC)'/'#endif'
|
||||
- distinguish between "yacc stack overflow" and "memory exhausted" situations
|
||||
- consolidated termination cleanup code; introduced yyreturn, set to 2 after
|
||||
labels yyoverflow/yyenomem, set to 1 after label yyabort, set to 0 after
|
||||
label yyaccept; all termination cases jump to label yyreturn, which does
|
||||
any cleanup then returns yyreturn value
|
||||
- replaced YYDELETEVAL & YYDELETEPOSN user-supplied macro capability by
|
||||
implementation of byacc-generated yydestruct() as defined by bison
|
||||
compatible %destructor mechanism
|
||||
- moved invocation of 'YYREDUCEPOSNFUNC' macro to immediately prior to, rather
|
||||
than after, execution of final rule action (so that, at some future
|
||||
date, implementation extensions can be added to enable custom calculation
|
||||
of locations associated with non-terminals within rule actions); deleted
|
||||
unnecessary flag 'reduce_posn'; deleted 'YYCALLREDUCEPOSN' macro; deleted
|
||||
C++ variant of 'YYREDUCEPOSNFUNC' invocation
|
||||
- adopt approach similar to bison for default computation of yyloc; change
|
||||
macro 'YYREDUCEPOSNFUNC' name to 'YYLLOC_DEFAULT' for bison compatibility;
|
||||
added 'yyerror_loc_range[2]' to hold start & end locations for error
|
||||
situations that pop the stack
|
||||
- use 'YYINT' rather than 'short' for integer table types, and for indexing
|
||||
parser tables
|
||||
|
||||
readskel.c
|
||||
http://www.verisign.com/index.html- replaced error() with fprintf()
|
||||
|
||||
mstring.h
|
||||
- moved contents of mstring.h to defs.h - mstring.h is obsolete
|
||||
|
||||
mstring.c
|
||||
- replaced include of mstring.h with defs.h
|
||||
- changed 'START' to 'HEAD' to remove conflict with 'START' used for
|
||||
the start symbol defined in defs.h
|
||||
|
||||
modified byacc files:
|
||||
---------------------
|
||||
|
||||
skeleton.c
|
||||
- skeleton.c is now generated from the appropriate skeleton file by 'skel2c'
|
||||
|
||||
configure.in
|
||||
- added configuration for --enable-btyacc option; if 'yes' add '-DYYBTYACC'
|
||||
to DEFINES in makefile.in; --enable-btyacc defaults to 'no'
|
||||
- added configuration for --with-max-table-size option; if present,
|
||||
overrides the value of MAXTABLE defined in defs.h
|
||||
- regenerate configure using autoconf
|
||||
|
||||
makefile.in
|
||||
- added mstring.c to C_FILES
|
||||
- added mstring$o to OBJS
|
||||
- added @DEFINES@ as value of DEFINES make variable
|
||||
- added new make variable SKELETON with value 'yaccpar.skel'
|
||||
- added rule to generate skeleton.c from $(SKELETON), depending on skel2c
|
||||
and makefile
|
||||
- added rm -f skeleton.c distclean rule
|
||||
- moved dependency on makefile from only main$o & skeleton$o to $(OBJS),
|
||||
since if ./configure is run changing, for example, from --enable-btyacc
|
||||
to --disable-btyacc, all files must be recompiled to ensure a clean
|
||||
executable
|
||||
- add @MAXTABLE@ for optional '-DMAXTABLE=nnn' if configured using
|
||||
--with-max-table-size=nnn
|
||||
- changed 'cd test && rn 0f test-*'to 'rm -f $(testdir)/test-*'
|
||||
|
||||
test/run_test.sh
|
||||
- ???
|
||||
|
||||
test/run_make.sh
|
||||
- ???
|
||||
|
||||
defs.h
|
||||
- moved contents of mstring.h to defs.h - mstring.h is obsolete
|
||||
- added <limits.h> to get the various system defined machine limits;
|
||||
changed definitions of MAXCHAR, MAXSHORT, MINSHORT & BITS_PER_WORD to use
|
||||
defines from <limits.h>; changed definitions of BIT and SETBIT to use
|
||||
value of BITS_PER_WORD
|
||||
- added typedef for __compar_fn_t, conditioned on _COMPAR_FN_T being
|
||||
undefined (at least for Mac OSX environment)
|
||||
- adopt new symbol class values ACTION and ARGUMENT
|
||||
- adopt changes/additions used by inherited attribute processing
|
||||
- clean up locations of extern function definitions to match where they
|
||||
actually live in source files
|
||||
- adopt error functions from inherited attribute processing; added new error
|
||||
functions
|
||||
- added keyword code LOCATIONS for %locations
|
||||
- added keyword code DESTRUCTOR for %destructor
|
||||
- added extern decl for 'int locations'; true if %locations present
|
||||
- added extern decl for 'int backtrack'; initialized to 0 (= false), set to
|
||||
1 (= true) if -B flag is present
|
||||
- added extern decl for 'int destructor'; true if at least one %destructor
|
||||
present in grammar spec file
|
||||
- define 'YYINT' as the smallest C type that can be used to address a
|
||||
table of size 'MAXTABLE'; define 'YYINT' based on the value of
|
||||
'MAXTABLE' using the standard system type size definitions from <limits.h>;
|
||||
define 'MAXYYINT' and 'MINYYINT' accordingly
|
||||
- change 'Value_t' and 'Index_t' to 'YYINT' from 'short'
|
||||
- allow 'MAXTABLE' to be defined by '-DMAXTABLE=nnn' at compile-time
|
||||
|
||||
closure.c
|
||||
- changed print_closure(), print_EFF() and print_first_derives() to 'static';
|
||||
added fwd declarations
|
||||
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
|
||||
used for variables/parameters that were related to variables/parameters
|
||||
declared as 'short'
|
||||
|
||||
error.c
|
||||
- adopt error functions from inherited attribute processing; added a few
|
||||
additional inherited attribute error functions
|
||||
|
||||
graph.c
|
||||
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
|
||||
used for variables/parameters that were related to variables/parameters
|
||||
declared as 'short'
|
||||
|
||||
lalr.c
|
||||
- changed MAXSHORT to MAXYYINT
|
||||
|
||||
lr0.c
|
||||
- changed MAXSHORT to MAXYYINT
|
||||
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
|
||||
used for variables/parameters that were related to variables/parameters
|
||||
declared as 'short'
|
||||
|
||||
main.c
|
||||
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
|
||||
used for variables/parameters that were related to variables/parameters
|
||||
declared as 'short'
|
||||
|
||||
mkpar.c
|
||||
- backtracking attempts to resolve shift/reduce and reduce/reduce conflicts
|
||||
|
||||
output.c
|
||||
- generate prefix & YYPREFIX defines into externs file (-i, .tab.i) and
|
||||
code file (-r, .code.c); generate into output file (.tab.c) only if not
|
||||
using -r option; eliminates doubled output of prefix aliases if -r with
|
||||
no -i in y.tab.c and y.code.c or if -r & -i in y.tab.i and y.code.c
|
||||
- changed types of generated string tables to be 'const pointer to const char'
|
||||
- adopt backtracking as an alternative in cases where otherwise we have a
|
||||
conflict in the parsing actions (3, rather than 2, choices)
|
||||
- wrap defines file with (where "yy" is value of 'symbol_prefix')
|
||||
#ifndef __yy_defines_h_
|
||||
#define _yy_defines_h_
|
||||
|
||||
<defines>
|
||||
|
||||
#endif
|
||||
- avoid writing %%xdecls skeleton section twice if -r used
|
||||
- eliminated 'body_3' and 'trailer_2' skeleton segments - no need to generate
|
||||
yyerror() invocation dynamically; YYERROR_CALL() is already generated
|
||||
earlier, and can be used in the pareser skeleton
|
||||
- if -P flag (pure_parser), add yylloc as 2nd parameter to yylex()
|
||||
(declaration & call)
|
||||
- change YYPOSN to YYLTYPE and yyposn to yylloc (position corresponding to
|
||||
yylval) for bison compatibility; add yyloc (corresponding to yyval)
|
||||
- generate yylloc parameters for yylex & yyerror if %locations present
|
||||
- add location as 1st parameter to declaraion & invocation of yyerror() if
|
||||
%locations present
|
||||
- output backtrack parsing tables if -B flag is present
|
||||
- added generation of yystos[] with output_accessing_symbols() to allow
|
||||
translation from a parser internal state number to the corresponding
|
||||
grammar symbol number [0 .. nsyms) of the accessing symbol of that parser
|
||||
state; used in the generated code for YYDESTRUCT_CALL() &
|
||||
YYSTYPE_TOSTRING() to enable the correct semantic value union tag to be
|
||||
determined when executing the implementation of YYDESTRUCT_CALL() or
|
||||
YYSTYPE_TOSTRING() (similar to yystos[] in bison)
|
||||
- added to output_prefix(): yystos; yycindex & yyctable if compiling
|
||||
backtracking; yyloc & yylloc if %locations used
|
||||
- extended yyname[] to include all grammar symbols, not just the terminal
|
||||
symbols: '$end', 'error', '$accept', all non-terminals, including internally
|
||||
generated non-terminals for embedded actions in rules, and 'illegal-symbol'
|
||||
(which bison spells '$undefined'); '$end' already defined as a symbol 0,
|
||||
rathern than adding 'end-of-file' as the name of symbol 0; added
|
||||
'illegal-symbol' from byacc-20140101 (NOTE: the comment in the code that
|
||||
says byacc does not predefine '$end' and '$error' is incorrect; however,
|
||||
both bison and byacc spell '$error' as 'error')
|
||||
- added generation of #define YYTRANSLATE() from byacc-20140101, but changed
|
||||
the definition for the undefined symbol case because it is no longer in
|
||||
yyname[YYMAXTOKEN+1] but rather occurs after the last non-terminal symbol;
|
||||
added #define YYUNDFTOKEN to contain the index in yyname of 'illegal-symbol'
|
||||
- generate YYLTYPE in output_ltype() as a struct like for bison rather than
|
||||
using #define in yaccpar.skel
|
||||
- added 'write_code_lineno' invocation at start of 'output_prefix'
|
||||
- added 'write_code_lineno' invocation at start of 'output_pure_parser'
|
||||
- added 'write_code_lineno' invocation prior to generation of #include
|
||||
for externs file
|
||||
- added 'write_code_lineno' invocation after 1st 'write_section(fp, xdecls)'
|
||||
- added '++outline;' prior to output of '#define YYTRANSLATE' - this was
|
||||
actually causing almost all of the invocations of 'write_code_lineno' to
|
||||
put out the correct #line directive
|
||||
- corrected 'write_code_lineno' - the line number in a #line directive is
|
||||
the number of the next line, not the number of the #line line
|
||||
- changed MAXSHORT to MAXYYINT; changed 'high' local static from 'int' to
|
||||
'long' so that it can get higher than 'MAXYYINT' without machine-dependent
|
||||
behavior; changed related formats from '%d' to '%ld'
|
||||
- generate 'YYINT' rather than 'short' for integer table types
|
||||
- generate YYDESTRUCT_DECL & YYDESTRUCT_CALL macros, similar to YYERROR_DECL
|
||||
and YYERROR_CALL macros, that can be redefined by user, if desired, to add
|
||||
additional parameters to yydestruct() (and even change the 'yydestruct'
|
||||
function name)
|
||||
- if at least one %destructor present, generate yydestruct(); 1st parameter
|
||||
is a string indicating the context in which yydestruct() is invoked
|
||||
(e.g., discarding input token, discarding state on stack, cleanup when
|
||||
aborting); 2nd parameter is the internal grammar symbol number [0..nsyms)
|
||||
of the accessing symbol of the parser state on the top of the stack; 3rd
|
||||
parameter is a pointer to the semantic value to be reclaimed associated
|
||||
with the grammar symbol in the 2nd parameter; if %locations is defined,
|
||||
the 4th parameter is a pointer to the position value to be reclaimed
|
||||
associated with the grammar symbol in the 2nd parameter
|
||||
|
||||
reader.c
|
||||
- adopt []-actions, similar to {}-actions; {}-actions are only executed when
|
||||
not in trial mode, but []-actions are executed regardless of mode
|
||||
- adopt new symbol class values ACTION and ARGUMENT
|
||||
- adopt inherited attributes (syntax resembles arguments to non-terminal
|
||||
symbols)
|
||||
- adopt keyword table lookup from btyacc, modified to handle equivalence
|
||||
of '-' and '_' in spelling of keywords
|
||||
- adopt refactoring of tag table creation into cache_tag() for use in
|
||||
multiple locations
|
||||
- added new error functions in place of btyacc's generic error() function
|
||||
- changed '0' to 'NULL' for pointer initialization
|
||||
- reworked for-loop at end of get_line (part of DEFERRED '%ifdef/%endif' change)
|
||||
- added %locations directive for bison compatibility to enable position
|
||||
processing
|
||||
- added decl for 'int locations'; true if %locations present
|
||||
- added decl 'int backtrack'; initialized to 0 (= false), set to
|
||||
1 (= true) if -B flag is present
|
||||
- process %locations if present, set location = 1
|
||||
- only process []-actions and only generate 'if (!yytrial)' prefix for
|
||||
{}-actions if backtracking is enabled
|
||||
- add decl for 'int destructor'; true if at least one %destructor is present
|
||||
- add %destructor directive to enable semantic & position stack processing to
|
||||
reclaim memory associated with discarded symbols
|
||||
- process bison compatible %destructor (set destructor = 1); support @$ in
|
||||
%destructor code to reference the position value if %locations is defined
|
||||
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
|
||||
used for variables/parameters that were related to variables/parameters
|
||||
declared as 'short'
|
||||
- if %locations present, support @N and @$ syntax as for bison to reference
|
||||
the locations associated with the N-th rhs symbol and the lhs symbol,
|
||||
respectively
|
||||
|
||||
symtab.c
|
||||
- initialize fields added to 'struct bucket' for non-terminal symbol
|
||||
inherited attributes
|
||||
|
||||
verbose.c
|
||||
- for parse states with conflicts, the contents of the y.output file include
|
||||
the trial shift and/or trial reduce actions
|
||||
- added output to the end of the verbose report showing the correspondance
|
||||
between grammar symbol #, internal parser symbol #, and grammar symbol name
|
||||
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
|
||||
used for variables/parameters that were related to variables/parameters
|
||||
declared as 'short'
|
||||
|
||||
yacc.1
|
||||
- added options 'P', 'V', 'y' and '-o output_file' to the yacc command
|
||||
synopsis (already covered in the description section)
|
||||
- added options 'B', 'D' and 'L' to the yacc command synopsis; added text in
|
||||
the description section
|
||||
- added %locations description to the extensions section

NOTE: README.BTYACC needs to be re-written (or another README file created)
|
||||
to explain how the extensions were adopted into the byacc-20140101 baseline.
|
||||
|
||||
bytacc changes adopted; see README.BTYACC for details.
|
||||
------------------------------------------------------
|
||||
|
||||
Changes to the skeleton to send debugging output to stderr.
|
||||
|
||||
Changes to the types of the grammar tables from 'short' to 'int' if
|
||||
MAXTABLE is defined to be > MAXSHORT for generation of large grammar tables
|
||||
for large grammars. This can be set with the invocation of configure
|
||||
using the --with-max-table-size=N option
|
||||
|
||||
Changes to add syntactic sugaring for definition and semantic processing
|
||||
of inherited attributes associated with non-terminal symbols on the rhs of
|
||||
rules. Inherited attributes are implemented as {}-actions, and as such may
|
||||
introduce reduce/reduce conflicts. The advantage over manual {}-actions is
|
||||
that checking is performed on the number and types of inherited attributes,
|
||||
and the positions on the semantic stack are automatically calculated.
|
||||
Identical actions produced by the inherited attribute syntax are collapsed
|
||||
into a single action, reducing reduce/reduce conflicts.
|
||||
|
||||
The %type specification is extended to define the types of inherited
|
||||
attributes associated with non-terminal symbols on the lhs of rules, in
|
||||
addition to its original purpose in yacc for specifying the type of the
|
||||
symbol itself on the parser's value stack. In order to permit the two
|
||||
aspects to be used independently, the <type> specification following
|
||||
%type is optional.
|
||||
|
||||
Added a mechanism to the parser skeleton for computing and propagating
|
||||
the text position of grammar symbols if %locations directive is present in
|
||||
the grammar specificaion, or if yacc is invoked with the -L flag. Includes
|
||||
support for "@$" and "@N" (for N an integer) in actions to refer to symbol
|
||||
locations.
|
||||
|
||||
Added a bison compatible %destructor directive to define a memory
|
||||
management mechanism to the parser skeleton that enables cleanup of semantic
|
||||
values and text positions associated with the parsing stack that are
|
||||
automatically discarded during error processing.
|
||||
|
||||
The following is only available if configure is invoked with the
|
||||
--enable-btyacc=yes:
|
||||
|
||||
Changes to enable backtracking with semantic disambiguation, if yacc is
|
||||
invoked with the -B flag. A yacc parser disambiguates shift/reduce conflicts
|
||||
by choosing to shift, and reduce/reduce conflicts by reducing using the
|
||||
earliest grammar rule (in the grammar specification). A btyacc parser handles
|
||||
a conflict by remembering the current parse point and entering into trial parse
|
||||
mode. In trial parse mode, the parser tries each of the conflicting options
|
||||
until the first successs or until all options are exhausted. If the parser
|
||||
runs into an error while in trial parse mode, it backtracks to the most recent
|
||||
conflict point and tries the next alternative. If the parser finds a
|
||||
successful parse, it backtracks to the point where it first entered trial parse
|
||||
mode and continues with normal parsing, using the action at the start of the
|
||||
successful trial path. Success in trial parse mode is achieved either by
|
||||
successfully reducing the start symbol at the end of input or by invocation of
|
||||
YYVALID (or YYVALID_NESTED). Semantic disambiguation is supported within
|
||||
[]-actions, which are always executed, with invocation of YYERROR to terminate
|
||||
a trial path or YYVALID (and YYVALID_NESTED). Yacc {}-actions are only
|
||||
executed during normal parsing.
|
||||
|
||||
|
||||
btyacc changes deferred:
|
||||
------------------------
|
||||
|
||||
The -S command line flag to enable use of an alternate parser skeleton,
|
||||
read from an external file.
|
||||
|
||||
Preprocessor statements: %define, %ifdef/%endif, %include.
|
||||
|
||||
|
||||
btyacc changes rejected:
|
||||
------------------------
|
||||
|
||||
The yyerror_detailed() option for error messages is replaced by the
|
||||
byacc feature for specifying options paramters to yyerror().
|
||||
|
||||
C++-specific features in the parser skeleton.

BTYACC -- backtracking yacc
|
||||
===========================
|
||||
|
||||
BTYACC was created by Chris Dodd using ideas from many
|
||||
places and lots of code from the Berkeley Yacc
|
||||
distribution, which is a public domain yacc clone put
|
||||
together by the good folks at Berkeley. This code is
|
||||
distributed with NO WARRANTY and is public domain.
|
||||
It is certain to contain bugs, which you should
|
||||
report to: chrisd@collins.com.
|
||||
|
||||
Vadim Maslov of Siber Systems <vadik@siber.com>
|
||||
considerably modified BTYACC to make it suitable
|
||||
for production environment.
|
||||
|
||||
Several people have suggested bug fixes that
|
||||
were incorporated into BtYacc.
|
||||
|
||||
See the README.BYACC files for more about
|
||||
Berkeley Yacc and other sources of info.

Version 3.0 changes
|
||||
-------------------
|
||||
by Vadim Maslov
|
||||
|
||||
Changes mostly occurred in btyaccpa.ske file that
|
||||
contains the parsing shift/reduce/backtrack algorithm.
|
||||
|
||||
Version 3.0 innovations focus on:
|
||||
- text position computation and propagation,
|
||||
- industrial-strength error processing and recovery.
|
||||
|
||||
|
||||
** Added mechanism for computing and propagating
|
||||
text position of tokens and non-terminals.
|
||||
|
||||
Compilers often need to build AST trees such that every node
|
||||
in a tree can relate to the parsed program source it came from.
|
||||
The following applications are very likely to need this:
|
||||
- debuggers that show actual source of the debugged program,
|
||||
- source-to-source translators that want
|
||||
unchanged parts of the tree to generate the unchanged code.
|
||||
|
||||
The new YYPOSN mechanism added in this version of BtYacc
|
||||
helps you in automating the text position computation
|
||||
and in assigning the computed text positions to the AST.
|
||||
This mechanism is successfully used in commercial
|
||||
parsers and source-to-source translators.
|
||||
|
||||
In standard Yaccs every token and every non-terminal
|
||||
has an YYSTYPE semantic value attached to it.
|
||||
In this new version every token and every non-terminal
|
||||
also has an YYPOSN text position attached to it.
|
||||
YYPOSN is a user-defined type that can be anything and
|
||||
that has a meaning of text position attached to
|
||||
token or non-terminal.
|
||||
|
||||
In addition to semantic value stack BtYacc now maintains
|
||||
text position stack. Behavior of the text position stack
|
||||
is similar to the behavior of the semantic value stack.
|
||||
|
||||
If using text position mechanism,
|
||||
you need to define the following:
|
||||
|
||||
YYPOSN Preprocessor variable that contains C/C++ type of
|
||||
the text position attached to
|
||||
every token and non-terminal.
|
||||
|
||||
yyposn Global variable of type YYPOSN.
|
||||
The lexer must assign text position of
|
||||
the returned token to yyposn, just like it assigns
|
||||
semantic value of the returned token to yylval.
|
||||
|
||||
YYREDUCEPOSNFUNC
|
||||
Preprocessor variable that points to function that
|
||||
is called after the grammar rule reduction
|
||||
to reduce text positions located on the stack.
|
||||
|
||||
This function is called by BtYacc to reduce text
|
||||
positions. The function is called immediately after
|
||||
the regular rule reduction occurs.
|
||||
|
||||
The function has the following prototype:
|
||||
void ReducePosn(YYPOSN &ret,
|
||||
YYPOSN *terms,
|
||||
YYSTYPE *term_vals,
|
||||
int term_no,
|
||||
int stk_pos,
|
||||
int yychar,
|
||||
YYPOSN &yyposn,
|
||||
UserType extra);
|
||||
|
||||
The function arguments are:
|
||||
- ret
|
||||
Reference to the text position returned by
|
||||
the rule. The function must write the computed
|
||||
text position returned by the rule to ret.
|
||||
This is analogue of the $$ semantic value.
|
||||
|
||||
- term_posns
|
||||
Array of the right-hand side rule components
|
||||
YYPOSN text positions. These are analogues of
|
||||
$1, $2, ..., $N in the text position world.
|
||||
|
||||
- term_vals
|
||||
Array of the right-hand side (RHS) rule components
|
||||
YYSTYPE values. These are the $1,...,$N themselves.
|
||||
|
||||
- term_no
|
||||
Number of the components in RHS of the reduced rule.
|
||||
Equal to size of arrays term_posns and term_vals.
|
||||
Also equal to N in $1,...,$N in the reduced rule.
|
||||
|
||||
- stk_pos
|
||||
YYSTYPE/YYPOSN stack position before the reduction.
|
||||
|
||||
- yychar
|
||||
Lookahead token that immediately follows
|
||||
the reduced RHS components.
|
||||
|
||||
- yyposn
|
||||
YYPOSN of the token that immediately follows
|
||||
the reduced RHS components.
|
||||
|
||||
- extra
|
||||
User-defined extra argument passed to ReducePosn.
|
||||
|
||||
Typically this function extracts text positions from
|
||||
the right-hand side rule components and either
|
||||
assigns them to the returned $$ structure/tree or
|
||||
if no $$ value is returned, puts them into
|
||||
the ret text position from where
|
||||
it will be picked up by the later reduced rules.
|
||||
|
||||
YYREDUCEPOSNFUNCARG
|
||||
Extra user-defined argument passed to
|
||||
the ReducePosn function. This argument can use
|
||||
any variables defined in btyaccpa.ske.
|
||||
|
||||
|
||||
** Added code to btyaccpa.ske that automatically cleans up
|
||||
semantic semantic values and text positions of tokens
|
||||
and non-terminals that are discarded and deleted as
|
||||
a result of error processing.
|
||||
|
||||
In the previous versions the discarded token and non-terminal
|
||||
semantic values were not cleaned that caused quite severe
|
||||
leaks. The only way to fix it was to add garbage collection
|
||||
to YYSTYPE class.
|
||||
|
||||
Now BtYacc skeleton calls delete functions for semantic
|
||||
values and positions of the discarded tokens and
|
||||
non-terminals.
|
||||
|
||||
You need to define the following functions that BtYacc
|
||||
calls when it needs to delete semantic value or text position.
|
||||
|
||||
YYDELETEVAL
|
||||
User-defined function that is called by BtYacc
|
||||
to delete semantic value of the token or non-terminal.
|
||||
|
||||
The user-defined function must have the prototype:
|
||||
void DeleteYYval(YYSTYPE v, int type);
|
||||
v is semantic value to delete,
|
||||
type is one of the following:
|
||||
0 discarding token
|
||||
1 discarding state
|
||||
2 cleaning up stack when aborting
|
||||
|
||||
YYDELETEPOSN
|
||||
User-defined function that is called by BtYacc
|
||||
to delete text position of the token or non-terminal.
|
||||
|
||||
The user-defined function must have the prototype:
|
||||
void DeleteYYposn(YYPOSN p, int type);
|
||||
v is semantic value to delete,
|
||||
type is one of the following:
|
||||
0 discarding token
|
||||
1 discarding state
|
||||
2 cleaning up stack when aborting
|
||||
|
||||
|
||||
** User can define "detailed" syntax error processing
|
||||
function that reports an *exact* position of
|
||||
the token that caused the error.
|
||||
|
||||
If you define preprocessor variable YYERROR_DETAILED in
|
||||
your grammar then you need define the following
|
||||
error processing function:
|
||||
|
||||
void yyerror_detailed(char *text,
|
||||
int errt,
|
||||
YYSTYPE &errt_value,
|
||||
YYPOSN &errt_posn);
|
||||
|
||||
It receives the following arguments:
|
||||
text Error message.
|
||||
errt Code of the token that caused the error.
|
||||
errt_value Value of the token that caused the error.
|
||||
errt_posn Text position of token that caused error.
|
||||
|
||||
|
||||
** Dropped compatibility with C.
|
||||
|
||||
Compatibility with C became increasingly difficult
|
||||
to maintain as new features were added to btyaccpa.ske.
|
||||
So we dropped it. If anybody wants to make the new version
|
||||
compatible with C, we would gladly accept the changes.
|
||||
|
||||
Meanwhile we expect that you use C++ to write grammar
|
||||
actions and everything else in grammar files.
|
||||
Since C is (in a sense) subset of C++, your C-based
|
||||
grammar may work if you use C++ compiler to compile it.
|
||||
|
||||
Version 3.0 bugs fixed
|
||||
----------------------
|
||||
|
||||
Matthias Meixner <meixner@mes.th-darmstadt.de> fixed a bug:
|
||||
BtYacc does not correctly handle typenames, if one typename
|
||||
is a prefix of another one and if this type is used after
|
||||
the longer one. In this case BTYacc produces invalid code.
|
||||
|
||||
|
||||
Version 2.1 changes
|
||||
-------------------
|
||||
by Vadim Maslov
|
||||
|
||||
** Added preprocessor statements to BtYacc that are similar
|
||||
in function and behavior to C/C++ preprocessor statements.
|
||||
|
||||
These statements are used to:
|
||||
|
||||
- Introduce modularity into a grammar by breaking it
|
||||
into several *.y files and assembling different
|
||||
grammars from the *.y modules using %include and %ifdef.
|
||||
|
||||
- Have several versions of the same grammar
|
||||
by using %ifdef and $endif.
|
||||
|
||||
- To include automatically generated grammar fragment.
|
||||
For instance, we use %include to include
|
||||
automatically generated list of tokens.
|
||||
|
||||
Preprocessor statements are:
|
||||
|
||||
%define <var-name>
|
||||
Define preprocessor variable named <var-name>.
|
||||
|
||||
%ifdef <var-name>
|
||||
If preprocessor variable named <var-name>
|
||||
is defined by %define, then process the text from
|
||||
this %ifdef to the closing %endif.
|
||||
|
||||
%endif
|
||||
Closing bracket for %ifdef preprocessor statement.
|
||||
Only one nesting level of %ifdef-%endif is allowed.
|
||||
|
||||
%include <file-name>
|
||||
Process contents of the file named <file-name>.
|
||||
If <file-name> is a relative name, it is looked up
|
||||
in a directory in which btyacc was started.
|
||||
Only one nesting level of %include is allowed.
|
||||
|
||||
|
||||
Version 2.0 changes
|
||||
-------------------
|
||||
by Vadim Maslov
|
||||
|
||||
|
||||
** Changed 16-bit short numbers to 32-bit int numbers in
|
||||
grammar tables, so that huge grammar tables (tables that
|
||||
are larger than 32768 elements) resulting from huge
|
||||
grammars (Cobol grammar, for instance) can work correctly.
|
||||
You need to have 32-bit integer to index table bigger than
|
||||
32768 elements, 16-bit integer is not enough.
|
||||
|
||||
The original BtYacc just generated non-working tables
|
||||
larger than 32768 elements without even notifying about
|
||||
the table overflow.
|
||||
|
||||
|
||||
** Make error recovery work correctly when error happens
|
||||
while processing nested conflicts. Original BtYacc could
|
||||
infinitely cycle in certain situations that involved error
|
||||
recovery while in nested conflict.
|
||||
|
||||
More detailed explanation: when we have nested conflicts
|
||||
(conflict that happens while trial-processing another
|
||||
conflict), it leads btyacc into NP-complete searching of
|
||||
conflict tree. The ultimate goal is YYVALID operator that
|
||||
selects a particular branch of that tree as a valid one.
|
||||
|
||||
If no YYVALID is found on the tree, then error recovery
|
||||
takes over. The problem with this is that error recovery
|
||||
is started in the same state context that exists on the
|
||||
last surveyed branch of the conflict tree. Sometimes this
|
||||
last branch may be of zero length and it results in
|
||||
recovering to exactly the same state as existed before
|
||||
entering the conflict. BtYacc cycles then.
|
||||
|
||||
We solved this problem by memorizing the longest path in
|
||||
the conflict tree while browsing it. If we ever get into
|
||||
error recovery, we restore state that existed on the
|
||||
longest path. Effectively we say: if we have an error,
|
||||
let us move forward as far as we possibly could while we
|
||||
were browsing the conflict tree.
|
||||
|
||||
|
||||
** Introduce YYVALID_NESTED operation in addition to
|
||||
simply YYVALID. When we have a nested conflict (conflict
|
||||
while processing in trial mode for another conflict), we
|
||||
want to relate YYVALID to a particular level of conflict
|
||||
being in trial.
|
||||
|
||||
Since we mostly anticipate only 2-level nested conflicts
|
||||
YYVALID_NESTED tells the parser to satisfy only the
|
||||
internal conflict. Therefore, in 1-level conflict
|
||||
situation YYVALID_NESTED acts like a regular YYVALID, but
|
||||
in 2-level conflict it is a no-op and the other YYVALID
|
||||
for outer conflict will be searched for.
|
||||
|
||||
|
||||
** Improved handling of situation where /tmp directory is
|
||||
missing. Original btyacc just died quietly when /tmp
|
||||
directory was missing. We added code that states the
|
||||
problem explicitly. While on UNIX /tmp directory is always
|
||||
present, it may be missing on WIN32 systems, therefore
|
||||
diagnosing this situation is important.
|
||||
|
||||
|
||||
Version 1.0 changes: BackTracking
|
||||
=================================
|
||||
by Chris Dodd
|
||||
|
||||
BTYACC is a modified version of yacc that supports
|
||||
automatic backtracking and semantic disambiguation to
|
||||
parse ambiguous grammars, as well as syntactic sugar for
|
||||
inherited attributes (which tend to introduce conflicts).
|
||||
Whenever a btyacc generated parser runs into a
|
||||
shift-reduce or reduce-reduce error in the parse table, it
|
||||
remembers the current parse point (yacc stack and input
|
||||
stream state), and goes into trial parse mode. It then
|
||||
continues parsing, ignoring most rule actions. If it runs
|
||||
into an error (either through the parse table or through
|
||||
an action calling YYERROR), it backtracks to the most
|
||||
recent conflict point and tries a different alternative.
|
||||
If it finds a successful parse (reaches the end of the
|
||||
input or an action calls YYVALID), it backtracks to the
|
||||
point where it first entered trial parse mode, and
|
||||
continues with a full parse (executing all actions),
|
||||
following the path of the successful trial.
|
||||
|
||||
Actions in btyacc come in two flavors -- {}-actions, which
|
||||
are only executed when not in trial mode, and []-actions
|
||||
which are executed regardless of mode. There are also
|
||||
inherited attributes, which look like arguments (they are
|
||||
enclosed in "()") and act like []-actions.
|
||||
|
||||
What this buys you:
|
||||
|
||||
* No more lexer feedback hack. In yacc grammars for C, a
|
||||
standard hack, know as the "lexer feedback hack" is used
|
||||
to find typedef names. The lexer uses semantic
|
||||
information to decide if any given identifier is a
|
||||
typedef-name or not and returns a special token. With
|
||||
btyacc, you no longer need to do this; the lexer should
|
||||
just always return an identifier. The btyacc grammar then
|
||||
needs a rule of the form:
|
||||
|
||||
typename: ID [ if (!IsTypeName(LookupId($1))) YYERROR; ]
|
||||
|
||||
While the hack works adequately well for parsing C, it
|
||||
becomes a nightmare when you try to parse something like
|
||||
C++, where treating an ID as a typedef becomes heavily
|
||||
dependent on context.
|
||||
|
||||
* Easy disambiguation via simple ordering. Btyacc runs
|
||||
its trials via the rule "try shifting first, then try
|
||||
reducing by the order that the conflicting rules appear in
|
||||
the input file". This means you can deal with semantic a
|
||||
disambiguation rule like:
|
||||
[1] If it looks like a declaration it is, otherwise
|
||||
[2] If it looks like an expression it is, otherwise
|
||||
[3] it is a syntax error
|
||||
[Ellis&Stroustrup, Annotated C++ Reference Manual, p93]
|
||||
|
||||
To deal with this, you need only put all the rules for
|
||||
declarations before the rules for expressions in the
|
||||
grammar file.
|
||||
|
||||
* No extra cost if you do not use it. Backtracking is
|
||||
only triggered when the parse hits a shift/reduce or
|
||||
reduce/reduce conflict in the table. If you have no
|
||||
conflicts in your grammar, there is no extra cost, other
|
||||
than some extra code which will never be invoked.
|
||||
|
||||
* C++ and ANSI C compatible parsers. The parsers produced
|
||||
by btyacc can be compiled with C++ correctly. If you
|
||||
"#define" YYSTYPE to be some C++ type with constructor and
|
||||
destructor, everything will work fine. My favorite is
|
||||
"#define YYSTYPE SmartPointer", where SmartPointer is a
|
||||
smart pointer type that does garbage collection on the
|
||||
pointed to objects.
|
||||
|
||||
BTYACC was originally written to make it easy to write a
|
||||
C++ parser (my goal was to be able to use the grammar out
|
||||
of the back of the ARM with as few modifications as
|
||||
possible). Anyone who has ever looked at Jim Roskind
|
||||
public domain C++ yacc grammar, or the yacc-based grammar
|
||||
used in g++ knows how difficult this is. BTYACC is very
|
||||
useful for parsing any ambiguous grammar, particularly
|
||||
ones that come from trying to merge two (or more) complete
|
||||
grammars.
|
||||
|
||||
Limitations of the backtracking: Currently, the generated
|
||||
parser does NO pruning of alternate parsing paths. To
|
||||
avoid an exponential explosion of possible paths (and
|
||||
parsing time), you need to manually tell the parser when
|
||||
it can throw away saved paths using YYVALID. In practice,
|
||||
this turns out to be fairly easy to do. A C++ parser (for
|
||||
example) can just put a [YYVALID;] after every complete
|
||||
declaration and statement rule, corresponding to pruning
|
||||
the backtracking state after seeing a ';' or '}' -- there
|
||||
will never be a situation in which it is useful to
|
||||
backtrack past either of these.
|
||||
|
||||
Inherited attributes in btyacc:
|
||||
|
||||
Inherited attributes look a lot like function arguments to
|
||||
non-terminals, which is what they end up being in a
|
||||
recursive descent parser, but NOT how they are implemented
|
||||
in btyacc. Basically they are just syntactic sugar for
|
||||
embedded semantic actions and $0, $-1, ... in normal yacc.
|
||||
btyacc gives you two big advantages besides just the
|
||||
syntax:
|
||||
1. it does type checking on the inherited attributes,
|
||||
so you do not have to specify $<type>0 and makes sure
|
||||
you give the correct number of arguments (inherited
|
||||
attributes) to every use of a non-terminal.
|
||||
2. It "collapses" identical actions from that are produced
|
||||
from inherited attributes. This eliminates many
|
||||
potential reduce-reduce conflicts arising from
|
||||
the inherited attributes.
|
||||
|
||||
You use inherited attributes by declaring the types of the
|
||||
attributes in the preamble with a type declaration and
|
||||
declaring names of the attributes on the lhs of the yacc
|
||||
rule. You can of course have more than one rule with the
|
||||
same lhs, and you can even give them different names in
|
||||
each, but the type and number must be the same.
|
||||
|
||||
Here is a small example:
|
||||
/* lhs takes 2 inherited attributes */
|
||||
%type <t1> lhs(<t1>, <t2>)
|
||||
stuff(<t1>, <t2>)
|
||||
%%
|
||||
lhs($i1, $i2) : { $$ = $i1 }
|
||||
| lhs($i1, $i2) stuff($1,$i2) { $$ = $2; }
|
||||
|
||||
This is roughly equivalent to the following yacc code:
|
||||
lhs :
|
||||
{ $$ = $<t1>-1; }
|
||||
| lhs [ $<t1>$ = $-1; ] [ $<t2>$ = $<t2>0; ] stuff
|
||||
{ $$ = $4; }
|
||||
;
|
||||
|
||||
See the file "test/t2.y" for a longer and more complete
|
||||
example. At the current time, the start symbol cannot
|
||||
have any arguments.
|
||||
|
||||
Variant parsers:
|
||||
|
||||
Btyacc supports the -S flag to use a different parser
|
||||
skeleton, changing the way that the parser is called and
|
||||
used. The skeleton "push.skel" is included to produce a
|
||||
"passive" parser that you feed tokens to (rather than
|
||||
having the parser call a separate yylex routine). With
|
||||
push.skel, yyparse is defined as follows:
|
||||
|
||||
int yyparse(int token, YYSTYPE yylval)
|
||||
|
||||
You should call yyparse repeatedly with successive tokens
|
||||
of input. It returns 0 if more input is needed, 1 for a
|
||||
successful parse, and -1 for an unrecoverable parse error.
|
||||
|
||||
|
||||
Miscellaneous Features in ver. 1.0
|
||||
----------------------------------
|
||||
by Chris Dodd
|
||||
|
||||
The -r option has been implemented. The -r option tells
|
||||
Yacc to put the read-only tables in y.tab.c and the code and
|
||||
variables in y.code.c. Keith Bostic asked for this option so
|
||||
that :yyfix could be eliminated.
|
||||
|
||||
The -l and -t options have been implemented. The -l
|
||||
option tells Yacc not to include #line directives in the code
|
||||
it produces. The -t option causes debugging code to be
|
||||
included in the compiled parser.
|
||||
|
||||
The code for error recovery has been changed to
|
||||
implement the same algorithm as AT&T Yacc. There will still
|
||||
be differences in the way error recovery works because AT&T
|
||||
Yacc uses more default reductions than Berkeley Yacc.
|
||||
|
||||
The environment variable TMPDIR determines the directory
|
||||
where temporary files will be created. If TMPDIR is defined,
|
||||
temporary files will be created in the directory whose
|
||||
pathname is the value of TMPDIR. By default, temporary files
|
||||
are created in /tmp.
|
||||
|
||||
The keywords are now case-insensitive. For example,
|
||||
%nonassoc, %NONASSOC, %NonAssoc, and %nOnAsSoC are
|
||||
all equivalent.
|
||||
|
||||
Commas and semicolons that are not part of C code are
|
||||
treated as commentary.
|
||||
|
||||
Line-end comments, as in BCPL, are permitted. Line-end
|
||||
comments begin with // and end at the next end-of-line.
|
||||
Line-end comments are permitted in C code; they are converted
|
||||
to C comments on output.
|
||||
|
||||
The form of y.output files has been changed to look more
|
||||
like those produced by AT&T Yacc.
|
||||
|
||||
A new kind of declaration has been added.
|
||||
The form of the declaration is
|
||||
|
||||
%ident string
|
||||
|
||||
where string is a sequence of characters beginning with a
|
||||
double quote and ending with either a double quote or the
|
||||
next end-of-line, whichever comes first. The declaration
|
||||
will cause a #ident directive to be written near the start
|
||||
of the output file.
|
||||
|
||||
If a parser has been compiled with debugging code, that
|
||||
code can be enabled by setting an environment variable.
|
||||
If the environment variable YYDEBUG is set to 0, debugging
|
||||
output is suppressed. If it is set to 1, debugging output
|
||||
is written to standard output.
|
||||
|
||||
|
||||
Building BtYacc
|
||||
---------------
|
||||
by Chris Dodd and Vadim Maslov
|
||||
|
||||
We used GCC and GNU make to compile BtYacc both on UNIX and
|
||||
WIN32 paltforms. You are welcome to try different
|
||||
combinations of makes and compilers. Most likely it will
|
||||
work, but it may require Makefile changes.
|
||||
|
||||
There is no config script.
|
||||
Just type "make" and it should compile.
|
||||
|
||||
AWK. If you want to change file btyaccpa.ske (backtracking
|
||||
parser skeleton), you will need awk to compile it into
|
||||
skeleton.c file. We used GNU AWK (gawk) version 3.0.
|
||||
|
||||
It is known that using older versions of gawk
|
||||
may create problems in compilation, because older awks
|
||||
have problems with backslashes at the end of a line.
|
||||
|
||||
For MSDOS, there a "makefile.dos" that should do the trick.
|
||||
Note: makefile.dos was not tested for a long time.
|
||||
|
||||
The result of compilation should be a single executable called
|
||||
"btyacc" which you can install anywhere you like;
|
||||
it does not require any other files in the distribution to run.
|
||||
