* src/reader.c (copy_at, copy_dollarm parse_braces, parse_action)
(parse_guard): Rename the formal argument `stack_offset' as
`rule_length', which is more readable.
Adjust callers.
(copy_at, copy_dollar): Instead of outputting the hard coded
values of $$, $n and so forth, output invocation to b4_lhs_value,
b4_lhs_location, b4_rhs_value, and b4_rhs_location.
Note: this patch partially drops `semantic-parser' support: it
always does `rule_length - n', where semantic parsers ought to
always use `-n'.

space differences from 1_29-branch.
Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).
(union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
constructors or destructors.
(yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.
2002-04-23 Akim Demaille <[email protected]>

* tests/regression.at (Web2c Actions): Adjust.
2002-04-22 Akim Demaille <[email protected]>
* src/reader.c (token_translations_init): 256 is now the default
value for the error token, i.e., it will be assigned another
number if the user assigned 256 to one of her tokens.
(reader): Don't force 256 to error.
* doc/bison.texinfo (Symbols): Adjust.
* tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
(AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
etc. instead of 10, 20, 30 (which was used to `jump' over error
(256) and undefined (2)).
2002-04-22 Akim Demaille <[email protected]>
Propagate more token_number_t.
* src/gram.h (token_number_as_item_number)
(item_number_as_token_number): New.

2002-04-10 Akim Demaille <[email protected]>
* src/system.h: Rely on HAVE_LIMITS_H.
Suggested by Paul Eggert.
2002-04-09 Akim Demaille <[email protected]>
* tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
full stderr, and strip it according to the bison options, instead
of composing the error message from different bits.
This makes it easier to check for several error messages.
Adjust all the invocations.
Add an invocation exercising the error token.
Add an invocation demonstrating a stupid error message.
(_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

2002-04-09 Akim Demaille <[email protected]>
* src/gram.h, src/gram.c (error_token_number): Remove, use
errtoken->number.

for $undefined, as it uselessly prevents using it.
* src/gram.h (token_number_t): Move to...
* src/symtab.h: here.
(state_t.number): Is a token_number_t.
* src/print.c, src/reader.c: Use undeftoken->number instead of
hard coded 2.
(Even though this 2 is not the same as above: the number of the
undeftoken remains being 2, it is its user token number which
might not be 2).
* src/output.c (prepare_tokens): Rename the `maxtok' muscle with
`user_token_number_max'.
Output `undef_token_number'.
* data/bison.simple, data/bison.c++: Use them.
Be sure to map invalid yylex return values to
`undef_token_number'. This saves us from gratuitous SEGV.

2002-04-08 Akim Demaille <[email protected]>
* src/gram.h (item_number_t): New, the type of item numbers in
RITEM. Note that it must be able to code symbol numbers as
positive number, and the negation of rule numbers as negative
numbers.
Adjust all dependencies (pretty many).
* src/reduce.c (rule): Remove this `short *' pointer: use
item_number_t.
* src/system.h (MINSHORT, MAXSHORT): Remove.
Include `limits.h'.
Adjust dependencies to using SHRT_MAX and SHRT_MIN.

* data/bison.simple, data/bison.c++: Adjust.
* tests/torture.at (Big triangle): Move the limit from 254 to
500.
* tests/regression.at (Web2c Actions): Ajust.
Trying with bigger grammars shows various phenomena: at 3000 (28Mb
of grammar file) bison is killed by my system, at 2000 (12Mb) bison
passes, but produces negative #line number, once fixed, GCC is
killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
C), it passes.
* src/state.h (state_h): Code input lines on ints, not shorts.
2002-04-08 Akim Demaille <[email protected]>

New.
Use them to define yy_token_number_type/TokenNumberType.
Use this type for yytranslate.
* tests/torture.at (Big triangle): Push the limit from 124 to
253.
* tests/regression.at (Web2c Actions): Adjust.
2002-04-07 Akim Demaille <[email protected]>

2002-04-07 Akim Demaille <[email protected]>
* src/lalr.c, src/LR0.c, src/closure.c, src/gram.c, src/reduce.c:

newly created state.
Adjust to initialize first_state and last_state if needed.
Be sure to distinguish the initial from the final state.
(new_states): Create the itemset of the initial state, and use
new_state.
* src/closure.c (closure): Now that the initial state has its
items properly set, there is no need for a special case when

2002-04-07 Akim Demaille <[email protected]>
* src/reduce.c (inaccessable_symbols): Fix a buglet: because of a

(prepare): here.
* src/system.h (DEFAULT_TMPDIR): New.
2002-02-14 Paul Eggert <[email protected]>
Remove the support for C++ namespace cleanliness; it was
causing more problems than it was curing, since it didn't work
properly on some nonstandard C++ compilers. This can wait
for a proper C++ parser.
* NEWS: Document this.
* doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
of C++, as it's treated like C now.
* src/bison.simple (YYSTD): Remove.
(YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
Treat C++ just like Standard C instead of trying to support

* tests/input.at: New.
2002-02-07 Robert Anisko <[email protected]>

more consistent when naming methods and variables. Put preprocessor
directives around tables only needed for debugging.
2002-02-07 Robert Anisko <[email protected]>

C++ parsers.
(yy::b4_name::parse): Use print_.

not expanded by m4.
2002-02-05 Akim Demaille <[email protected]>
* data/bison.c++: Adjust to the M4 back end.
More is certainly needed.
2002-02-05 Akim Demaille <[email protected]>
Give a try to M4 as a back end.
* lib/readpipe.c: New, from wdiff.
* src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
BISON_HAIRY.
* src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
specific values. Now it is m4 that performs the lookup.
* src/parse-skel.y: Remove.
* src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
* src/output.c (actions_output, guards_output)
(token_definitions_output): No longer keeps track of the output
line number, hence remove the second argument.
(guards_output): Check against the guard member of a rule, not the
action member.
Adjust callers.
(output_skeleton): Don't look for the skeleton location, let m4 do
that.
Create `/tmp/muscles.m4'. This is temporary, a proper temporary
file will be used.
Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
(prepare): Given that for the time being changesyntax is not
usable in M4, rename the muscles using `-' to `_'.
Define `defines_flag', `output_parser_name' and `output_header_name'.
* src/output.h (actions_output, guards_output)
(token_definitions_output): Adjust prototypes.
* src/scan-skel.l: Instead of scanning the skeletons, it now
processes the output of m4: `__oline__' and `#output'.
* data/bison.simple: Adjust to be used by M4(sugar).
* tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
to date.
* tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
* data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
shamelessly stolen from CVS Autoconf.
2002-02-05 Akim Demaille <[email protected]>
* lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
* configure.in: Check for the declarations of free and malloc.
* src/muscle_tab.c: Adjust.
2002-02-05 Akim Demaille <[email protected]>
* src/muscle_tab.c (muscle_init): Don't default to NULL muscle
which have no values.
2002-02-05 Akim Demaille <[email protected]>
* src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
* data/: here.
2002-01-29 Paul Eggert <[email protected]>
* src/bison.simple (YYSIZE_T): Do not define merely because
YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
On some platforms, <alloca.h> does not declare YYSTD (size_t).
2002-01-27 Akim Demaille <[email protected]>
Fix `%nonassoc and eof'.
* src/state.c (errs_dup): Aaaah! The failure was due to bytes
which were not properly copied! Replace
memcpy (res->errs, src->errs, src->nerrs);
with
memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
!!!
* tests/regression.at (%nonassoc and eof): Adjust to newest
Autotest: `.' is not in the PATH.
2002-01-27 Akim Demaille <[email protected]>
* tests/sets.at (AT_EXTRACT_SETS): New.
(Nullable): Use it.
(Firsts): New.
2002-01-26 Akim Demaille <[email protected]>
* tests/actions.at, tests/calc.at, tests/headers.at,
* tests/torture.at: Adjust to the newest Autotest which no longer
forces `.' in the PATH.
2002-01-25 Akim Demaille <[email protected]>
* tests/regression.at (%nonassoc and eof): New.
Suggested by Robert Anisko.
2002-01-24 Akim Demaille <[email protected]>
Bison dumps core when trying to complain about broken input files.
Reported by Cris van Pelt.
* src/lex.c (parse_percent_token): Be sure to set token_buffer.
* tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
into...

2002-01-20 Marc Autret <[email protected]>
* tests/output.at: New test.
* src/files.c (compute_base_names): Don't map extensions when
the YACC flag is set, use defaults.
Reported by Evgeny Stambulchik.
2002-01-20 Marc Autret <[email protected]>
* src/system.h: Need to define __attribute__ away for non-GCC
compilers as well (i.e. the vendor C compiler).
Suggested by Albert Chin-A-Young.
2002-01-11 Tim Van Holder <[email protected]>
* lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
canonical definition.
* src/system.h: Use the canonical definition for PARAMS (avoids
a conflict with the macro from lib/hash.h).
2002-01-11 Akim Demaille <[email protected]>
* configure.in: Use AC_FUNC_STRNLEN.
Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2002-01-09 Akim Demaille <[email protected]>
* src/files.c, src/files.h (output_infix): New.
(tab_extension): Remove.
(compute_base_names): Compute the former, drop the latter.
* src/output.c (prepare): Insert the muscles `output-infix', and
`output-suffix'.
* src/parse-skel.y (string, string.1): New.
(section.header): Use it.
(section.yacc): Remove.
(prefix): Remove too.
* src/scan-skel.l: Adjust.
* src/bison.simple, src/bison.hairy: Adjust.
2002-01-09 Akim Demaille <[email protected]>
* configure.in (WERROR_CFLAGS): Compute it.
* src/Makefile.am (CFLAGS): Pass it.
* tests/atlocal.in (CFLAGS): Idem.
* src/files.c: Fix a few warnings.
(get_extension_index): Remove, unused.
2002-01-08 Akim Demaille <[email protected]>
* src/getargs.c (AS_FILE_NAME): New.
(getargs): Use it to convert DOSish file names.
* src/files.c (base_name): Rename as full_base_name to avoid
clashes with `base_name ()'.
(filename_split): New.
(compute_base_names): N-th rewrite, using filename_split.
2002-01-08 Akim Demaille <[email protected]>
* lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
New, stolen from the Fileutils 4.1.
* lib/Makefile.am (libbison_a_SOURCES): Adjust.
* configure.in: Check for the presence of memrchr, and of its
prototype.
2002-01-07 Tim Van Holder <[email protected]>
* lib/hash.h (__P): Added definition for this macro.
* src/Makefile.am: Add parse-skel.c and scan-skel.c to
BUILT_SOURCES, to ensure they are generated first.
* src/parse-skel.y: Use YYERROR_VERBOSE instead of
%error-verbose to allow bootstrapping with bison 1.30x.
2002-01-06 Akim Demaille <[email protected]>
* src/reader.c (parse_braces): Don't fetch the next char, the
convention is to fetch on entry.
* tests/torture.at (GNU Cim Grammar): Reintroduce their weird
'switch' without a following semicolon.
* tests/regression.at (braces parsing): New.
2002-01-06 Akim Demaille <[email protected]>
Bison is dead wrong in its RR conflict reports.
* tests/torture.at (GNU Cim Grammar): New.
* src/conflicts.c (count_rr_conflicts): Fix.
2002-01-06 Akim Demaille <[email protected]>
Creating package.m4 from configure.ac causes too many problems.
* tests/Makefile.am (package.m4): Create it by hand,
AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
2002-01-06 Akim Demaille <[email protected]>
* src/Makefile.am (bison_SOURCES): Add parse-skel.h and
skeleton.h.
2002-01-04 Paul Eggert <[email protected]>
* doc/bison.texinfo (Debugging):
Remove YYSTDERR; it's no longer defined or used.
Also, s/cstdio.h/cstdio/.
2002-01-03 Akim Demaille <[email protected]>
* tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
2002-01-03 Akim Demaille <[email protected]>
* src/parse-skel.y (process_skeleton): Don't bind the parser's
tracing code to --trace, wait for a better --trace option, with
args.
2002-01-03 Akim Demaille <[email protected]>
* src/bison.simple (YYSTDERR): Remove, replace `stderr'.
The ISO C++ standard is extremely clear about it: stderr is
considered a macro, not a regular symbol (see table 94 `Header
<cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
Therefore std:: does not apply to it. It still does with fprintf.
Also, s/cstdio.h/cstdio/.
2002-01-03 Akim Demaille <[email protected]>
* lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
for non system headers.
2002-01-02 Akim Demaille <[email protected]>
Equip the skeleton chain with location tracking, runtime trace,
pure parser and scanner.
* src/parse-skel.y: Request a pure parser, locations, and prefix
renaming.
(%union): Having several members with the same type does not help
type mismatches, simplify.
(YYPRINT, yyprint): New.
(yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
(skel_error): this.
Handle locations.
* src/scan-skel.l: Adjust to these changes.
* src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
(LOCATION_PRINT, skel_control_t): New.
2001-12-30 Akim Demaille <[email protected]>
* src/parse-skel.y: Get rid of the shift/reduce conflict:
replace `gb' with BLANKS.
* src/scan-skel.l: Adjust.
2001-12-30 Akim Demaille <[email protected]>
* src/system.h: We don't need nor want bcopy.
Throw away MS-DOS crap: we don't need getpid.
* configure.in: We don't need strndup. It was even causing
problems: because Flex includes the headers *before* us,
_GNU_SOURCE is not defined by config.h, and therefore strndup was
not visible.
* lib/xstrndup.c: New.
* src/scan-skel.l: Use it.
Be sure to initialize yylval.muscle member when scanning a MUSCLE.
* src/parse-skel.y: Use %directives instead of #defines.
2001-12-30 Akim Demaille <[email protected]>
* src/skeleton.h: New.
* src/output.c (output_parser, output_master_parser): Remove, dead
code.
* src/output.h (get_lines_number, actions_output, guards_output)
(token_definitions_output): Prototype them.
* src/parse-skel.y: Add the license notice.
Include output.h and skeleton.h.
(process_skeleton): Returns void, and takes a single parameter.
* src/scan-skel.l: Add the license notice.
Include skeleton.h.
Don't use %option yylineno: it seems that then Flex imagines
REJECT has been used, and therefore it won't reallocate its
buffers (which makes no other sense to me than a bug). It results
in warnings for `unused: yy_flex_realloc'.
2001-12-30 Robert Anisko <[email protected]>
* src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
(MUSCLE_INSERT_PREFIX): ...to there.
* src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
(MUSCLE_INSERT_PREFIX): Move from here...
* src/bison.hairy: Add a section directive. Put braces around muscle
names. This parser skeleton is still broken, but Bison should not
choke on a bad muscle 'syntax'.
* src/bison.simple: Add a section directive. Put braces around muscle
names.
* src/files.h (strsuffix, stringappend): Add declarations.
(tab_extension): Add declaration.
(short_base_name): Add declaration.
* src/files.c (strsuffix, stringappend): No longer static. These
functions are used in the skeleton parser.
(tab_extension): New.
(compute_base_names): Use the computations done in this function
to guess if the generated parsers should have '.tab' in their
names.
(short_base_name): No longer static.
* src/output.c (output_skeleton): New.
(output): Disable call to output_master_parser, and give a try to
a new skeleton handling system.
(guards_output, actions_output): No longer static.
(token_definitions_output, get_lines_number): No longer static.
* configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
* src/Makefile.am (bison_SOURCES): Add scan-skel.l and
parse-skel.y.
* src/parse-skel.y: New file.
* src/scan-skel.l: New file.
2001-12-29 Akim Demaille <[email protected]>
%name-prefix is broken.
* src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
Adjust all dependencies.
* tests/headers.at (export YYLTYPE): Strengthen this test: use
%name-prefix.
Renaming yylval but not yylloc is not consistent. Now we do.
* src/bison.simple: Prefix yylloc if used.
* doc/bison.texinfo (Decl Summary): Document that.
2001-12-29 Akim Demaille <[email protected]>
* doc/bison.texinfo: Promote `%long-directive' over
`%long_directive'.
Remove all references to fixed-output-files, yacc is enough.
2001-12-29 Akim Demaille <[email protected]>
* src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
user prologue. These are defaults.
* tests/actions.at (Mid-rule actions): Make sure the user can
define YYDEBUG and YYERROR_VERBOSE.
2001-12-29 Akim Demaille <[email protected]>
* src/output.c (header_output): Don't forget to export YYLTYPE and
yylloc.
* tests/headers.at (export YYLTYPE): New, make sure it does.
* tests/regression.at (%union and --defines, Invalid CPP headers):
Move to...
* tests/headers.at: here.
2001-12-29 Akim Demaille <[email protected]>
* src/gram.h (rule_s): Member `assoc' is of type `associativity'.
2001-12-29 Akim Demaille <[email protected]>
* tests/actions.at (Mid-rule actions): Output on a single line
instead of several.
2001-12-29 Akim Demaille <[email protected]>
* doc/bison.texinfo: Formatting changes.
2001-12-29 Akim Demaille <[email protected]>
Don't store the token defs in a muscle, just be ready to output it
on command. Now possible via `symbols'. Fixes a memory leak.
* src/output.c (token_definitions_output): New.
(output_parser, header_output): Use it.
* src/reader.c (symbols_save): Remove.
2001-12-29 Akim Demaille <[email protected]>
* src/bison.simple: Do not provide a default for YYSTYPE and
YYLTYPE before the user's prologue. Otherwise it's hardly... a
default.
2001-12-29 Akim Demaille <[email protected]>
Mid-rule actions are simply... ignored!
* src/reader.c (readgram): Be sure to attach mid-rule actions to
the empty-rule associated to the dummy symbol, not to the host
rule.
* tests/actions.at (Mid-rule actions): New.
2001-12-29 Akim Demaille <[email protected]>
Memory leak.
* src/reader.c (reader): Free grammar.
2001-12-29 Akim Demaille <[email protected]>
Memory leak.
* src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
since it allocates it for each state, although only one is needed.
(allocate_storage): Do it here.
2001-12-29 Akim Demaille <[email protected]>
* src/options.h, src/options.c (create_long_option_table): Rename
as...
(long_option_table_new): this, with a clearer prototype.
(percent_table): Remove, unused,
* src/getargs.c (getargs): Adjust.
2001-12-29 Akim Demaille <[email protected]>
* src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
* src/print.c, src/print_graph.c, src/state.h: Rename state_table
as states.
2001-12-29 Akim Demaille <[email protected]>
* src/lalr.c (build_relations): Rename `states' as `states1'.
Sorry, I don't understand exactly what it is, no better name...
2001-12-29 Akim Demaille <[email protected]>
* src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
* src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
* src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
as rules.
2001-12-29 Akim Demaille <[email protected]>
* src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
ago.
2001-12-29 Akim Demaille <[email protected]>
* src/reader.c, src/reader.h (user_toknums): Remove.
Adjust all users to use symbols[i]->user_token_number.
2001-12-29 Akim Demaille <[email protected]>
* src/gram.c, src/gram.h (sprec, sassoc): Remove.
Adjust all users to use symbols[i]->prec or ->assoc.
2001-12-29 Akim Demaille <[email protected]>
* src/reader.c, src/reader.h (tags): Remove.
Adjust all users to use symbols[i]->tag.
2001-12-29 Akim Demaille <[email protected]>
* src/gram.h, src/gram.c (symbols): New, similar to state_table
and rule_table.
* src/reader.c (packsymbols): Fill this table.
Drop sprec.
* src/conflicts.c (resolve_sr_conflict): Adjust.
* src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
single table.
Use symbols[i]->tag instead of tags[i].
2001-12-29 Akim Demaille <[email protected]>
* tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
In addition, put a comment in there, to replace...
* tests/regression.at (%union and C comments): Remove.
2001-12-29 Akim Demaille <[email protected]>
* tests/regression.at (Web2c Actions): Blindly move the actual
output as expected output. The contents *seem* right to me, but I
can't pretend reading perfectly parser tables... Nonetheless, all
the other tests pass correctly, the table look OK, even though the
presence of `$axiom' is to be noted: AFAICS it is useless (but
harmless).
2001-12-29 Akim Demaille <[email protected]>
* src/reader.c (readgram): Don't add the rule 0 if there were no
rules read. In other words, add it _after_ having performed
grammar sanity checks.
Fixes the `tests/regression.at (Invalid input: 1)' Failure.
2001-12-29 Akim Demaille <[email protected]>
* tests/regression.at (Web2c Report): Catch up: the rule 0 is now
visible, and some states have now a different number.
2001-12-29 Akim Demaille <[email protected]>
* src/reader.c (readgram): Bind the initial rule's lineno to that
of the first rule.
* tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
(Solved SR Conflicts): Adjust rule 0's line number.
2001-12-29 Akim Demaille <[email protected]>
Fix the `GAWK Grammar' failure.
* src/LR0.c (final_state): Initialize to -1 so that we do compute
the reductions of the first state which was mistakenly confused
with the final state because precisely final_state was initialized
to 0.
* tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
now noticed by Bison.
* tests/regression.at (Rule Line Numbers): Adjust: state 0 does
have a reduction on $default.
2001-12-29 Akim Demaille <[email protected]>
* src/gram.c (ritem_print): Be sure to subtract 1 when displaying
rule line numbers.
* src/closure.c (print_closure): Likewise.
* src/derives.c (print_derives): Likewise.
* tests/sets.at (Nullable): Adjust: the rule numbers are correct
now.
2001-12-29 Akim Demaille <[email protected]>
* src/lalr.c (lookaheads_print): New.
(lalr): Call it when --trace-flag.
* tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
are dumped.
2001-12-29 Akim Demaille <[email protected]>
* src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
when walking through ritem, even via rule->rhs.
* src/reduce.c (dump_grammar, useful_production, reduce_output)
(useful_production, useless_nonterminals): Likewise.
(reduce_grammar_tables): Likewise, plus update nritems.
* src/nullable.c (set_nullable): Likewise.
* src/lalr.c (build_relations): Likewise.
* tests/sets.at (Nullable): Adjust.
Fortunately, now, the $axiom is no longer nullable.
2001-12-29 Akim Demaille <[email protected]>
* src/LR0.c (generate_states): Use nritems, not nitems, nor using
the 0-sentinel.
* src/gram.c (ritem_longest_rhs): Likewise.
* src/reduce.c (nonterminals_reduce): Likewise.
* src/print_graph.c (print_graph): Likewise.
* src/output.c (output_rule_data): Likewise.
* src/nullable.c (set_nullable): Likewise.
2001-12-29 Akim Demaille <[email protected]>
* src/output.c: Comment changes.
2001-12-27 Paul Eggert <[email protected]>
* src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
Sparc, as they were causing more porting problems than the
(minor) performance improvement was worth.
Also, catch up with 1.31's YYSTD.
2001-12-27 Akim Demaille <[email protected]>
* src/output.c (output_gram): Rely on nritems, not the
0-sentinel. See below.
Use -1 as separator, not 0.
* src/bison.simple (yyparse): Subtract 1 to the rule numbers.
Rely on -1 as separator in yyrhs, instead of 0.
* tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
twice `Now at end of input', therefore there are two lines less to
expect.
2001-12-27 Akim Demaille <[email protected]>
* tests/regression.at (Unresolved SR Conflicts):
(Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
below.
2001-12-27 Akim Demaille <[email protected]>
* src/LR0.c (new_state): Recognize the final state by the fact it
is reached by eoftoken.
(insert_start_shifting_state, insert_eof_shifting_state)
(insert_accepting_state, augment_automaton): Remove, since now
these states are automatically computed from the initial state.
(generate_states): Adjust.
* src/print.c: When reporting a rule number to the user, substract
1, so that the axiom rule is rule 0, and the first user rule is 1.
* src/reduce.c: Likewise.
* src/print_graph.c (print_core): For the time being, just as for
the report, depend upon --trace-flags to dump the full set of
items.
* src/reader.c (readgram): Once the grammar read, insert the rule
0: `$axiom: START-SYMBOL $'.
* tests/set.at: Adjust: rule 0 is now displayed, and since the
number of the states has changed (the final state is no longer
necessarily the last), catch up.
2001-12-27 Akim Demaille <[email protected]>
Try to make the use of the eoftoken valid. Given that its value
is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
is used instead of > 0 where appropriate, (ii), depend upon nritems
instead of the 0-sentinel.
* src/gram.h, src/gram.c (nritems): New.
Expected to be duplication of nitems, but for the time being...
* src/reader.c (packgram): Assert nritems and nitems are equal.
* src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
* src/closure.c (print_closure, print_fderives): Likewise.
* src/gram.c (ritem_print): Likewise.
* src/print.c (print_core, print_grammar): Likewise.
* src/print_graph.c: Likewise.
2001-12-27 Akim Demaille <[email protected]>
* src/main.c (main): If there are complains after grammar
reductions, then output the report anyway if requested, then die.
* src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
* src/reader.c (eoftoken): New.
(parse_token_decl): If the token being defined has value `0', it
is the eoftoken.
(packsymbols): No longer hack `tags' to insert `$' by hand.
Be sure to preserve the value of the eoftoken.
(reader): Make sure eoftoken is defined.
Initialize nsyms to 0: now eoftoken is created just like the others.
* src/print.c (print_grammar): Don't special case the eof token.
* src/regression.at: Adjust: `$' has value 0, not -1, which was a
lie anyway, albeit pleasant.
* tests/calc.at: Exercise error messages with eoftoken.
Change the grammar so that empty input is invalid.
Adjust expectations.
When yyungeting, be sure to use a valid yylloc: use last_yylloc.
2001-12-27 Akim Demaille <[email protected]>
* configure.in: Check the protos of strchr ans strspn.
Replace strchr if needed.
* src/system.h: Provide the protos of strchr, strspn and memchr if
missing.

* src/print.c, src/print_graph.c (escape): New.
Use it to quote the TAGS outputs.
* src/print_graph.c (print_state): Now errors are in red, and
reductions in green.
Prefer high to wide: output the state number on a line of its own.
2001-12-27 Akim Demaille <[email protected]>
* src/state.h, src/state.c (reductions_new): New.
* src/LR0.c (set_state_table): Let all the states have a
`reductions', even if reduced to 0.

* src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
* src/print.c (print_reductions, print_actions): Adjust.
* src/output.c (action_row): Adjust.
2001-12-27 Akim Demaille <[email protected]>
* src/state.h, src/state.c (errs_new, errs_dup): New.

(print_shifts, print_gotos, print_errs): New, extracted from...
(print_actions): here.
* src/print_graph.c (print_actions): Remove dead code.
2001-12-27 Akim Demaille <[email protected]>
* src/reader.c (copy_dollar, copy_at): Better checking of `n' in
`$n' and `@n'.
2001-12-27 Akim Demaille <[email protected]>
* src/lalr.c (add_lookback_edge): Use state_t instead of ints.
(build_relations): Adjust.
2001-12-27 Akim Demaille <[email protected]>
* src/lalr.c (set_goto_map): Remove a wrong but benign loop
duplication.
2001-12-27 Akim Demaille <[email protected]>
* src/reader.c (packgram): Catch nitems overflows.
2001-12-27 Akim Demaille <[email protected]>
* src/files.c, src/files.h (guard_obstack): Remove.
* src/output.c (output): Adjust.
* src/reader.c (parse_braces): New, factoring...
(copy_action, copy_guard): these two which are renamed as...
(parse_action, parse_guard): these.
As a voluntary consequence, using braces around guards is now
mandatory.
2001-12-27 Akim Demaille <[email protected]>
* src/gram.h (rule_t): `guard' and `guard_line' are new members.
* src/reader.c (symbol_list): `guard' and `guard_line' are new
members.
(symbol_list_new): Adjust.
(copy_action): action_line is the first line, not the last.
(copy_guard): Just as for actions, store the `action' only, not
the switch/case/break flesh.
Don't parse the user action that might follow the guard, let...
(readgram): do it, i.e., now, there can be an action after a
guard.
In other words the guard is just explicitly optional.
(packgram): Adjust.
* src/output.c (guards_output): New.
(output_parser): Call it when needed.
(output): Also free the guard and attrs obstacks.
* src/files.c, src/files.h (obstack_save): Remove.
(output_files): Remove.
As a result, if one needs the former `.act' file, using an
appropriate skeleton which requires actions and guards is now
required.
* src/main.c (main): Adjust.
* tests/semantic.at: New.
* tests/regression.at: Use `input.y' as input file name.
Avoid 8+3 problems by requiring input.c when the test needs the
parser.
2001-12-27 Akim Demaille <[email protected]>
* src/reader.c (symbol_list_new): Be sure to initialize all the
fields.
2001-12-27 Akim Demaille <[email protected]>
All the hacks using a final pseudo state are now useless.
* src/LR0.c (set_state_table): state_table holds exactly nstates.
* src/lalr.c (nLA): New.
(initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
instead of lookaheadsp from the pseudo state (nstate + 1).
2001-12-27 Akim Demaille <[email protected]>
* src/output.c (action_row, token_actions): Use a state_t instead
of a integer, and nlookaheads instead of the following state's
lookaheadsp.
2001-12-27 Akim Demaille <[email protected]>
* src/conflicts.c (log_resolution, flush_shift)
(resolve_sr_conflict, set_conflicts, solve_conflicts)
(count_sr_conflicts, count_rr_conflicts, conflicts_output)
(conflicts_print, print_reductions): Use a state_t instead of an
integer when referring to a state.
As much as possible, depend upon nlookaheads, instead of the
`lookaheadsp' member of the following state (since lookaheads of
successive states are successive, the difference between state n + 1
and n served as the number of lookaheads for state n).
* src/lalr.c (add_lookback_edge): Likewise.
* src/print.c (print_core, print_actions, print_state)
(print_results): Likewise.
* src/print_graph.c (print_core, print_actions, print_state)
(print_graph): Likewise.
* src/conflicts.h: Adjust.
2001-12-27 Akim Demaille <[email protected]>
* src/bison.hairy: Formatting/comment changes.
ANSIfy.
Remove `register' indications.
Add plenty of `static'.
2001-12-27 Akim Demaille <[email protected]>
* src/output.c (prepare): Drop the muscle `ntbase' which
duplicates ntokens.
* src/bison.simple: Formatting/comment changes.
Use YYNTOKENS only, which is documented, but not YYNTBASE, which
is an undocumented synonym.
2001-12-22 Akim Demaille <[email protected]>
* src/output.c (output_table_data): Change the prototype to use
`int' for array ranges: some invocations do pass an int, not a
short.
Reported by Wayne Green.
2001-12-22 Akim Demaille <[email protected]>
Some actions of web2c.y are improperly triggered.
Reported by Mike Castle.
* src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
* tests/regression.at (Web2c): Rename as...
(Web2c Report): this.
(Web2c Actions): New.
2001-12-22 Akim Demaille <[email protected]>
Reductions in web2c.y are improperly reported.
Reported by Mike Castle.
* src/conflicts.c (print_reductions): Fix.
* tests/regression.at (Web2c): New.
2001-12-18 Akim Demaille <[email protected]>
Some host fail on `assert (!"foo")', which expands to
((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
Reported by Nelson Beebee.
* src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
`#define it_succeeded 0' and `assert (it_succeeded)'.
2001-12-17 Marc Autret <[email protected]>
* src/bison.simple: Don't hard code the skeleton line and filename.
* src/output.c (output_parser): Rename 'line' as 'output_line'.
New line counter 'skeleton_line' (skeleton-line muscle).
2001-12-17 Paul Eggert <[email protected]>
* NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
YYDEBUG must be defined to a nonzero value.
* src/bison.simple (yytname): Do not assume that the user defines
YYDEBUG to a properly parenthesized expression.
2001-12-17 Akim Demaille <[email protected]>
* src/state.h (state_t): Rename lookaheads as lookaheadsp.
nlookaheads is a new member.
Adjust all users.
* src/lalr.h (nlookaheads): Remove this orphan declaration.
* src/lalr.c (initialize_lookaheads): Set nlookaheads for each
state.
2001-12-17 Akim Demaille <[email protected]>
* src/files.h, src/files.c (open_files, close_files): Remove.
* src/main.c (main): Don't open/close files, nor invoke lex_free,
let...

2001-12-17 Akim Demaille <[email protected]>
* src/conflicts.c (print_reductions): Formatting changes.
2001-12-17 Akim Demaille <[email protected]>
* src/conflicts.c (flush_shift): Also adjust lookaheadset.
(flush_reduce): New.
(resolve_sr_conflict): Adjust.
2001-12-17 Akim Demaille <[email protected]>
* src/output.c (output_obstack): Be static and rename as...
(format_obstack): this, to avoid any confusion with files.c's
output_obstack.
* src/reader.h (muscle_obstack): Move to...
* src/output.h: here, since it's defined in output.c.
2001-12-17 Akim Demaille <[email protected]>
* src/output.c (action_row, save_column, default_goto)
(sort_actions, matching_state, pack_vector): Better variable
locality.
2001-12-17 Akim Demaille <[email protected]>
* src/output.c: Various formatting changes.
2001-12-17 Akim Demaille <[email protected]>
* src/files.c (output_files): Free the output_obstack.
* src/main.c (main): Call print and print_graph conditionally.
* src/print.c (print): Work unconditionally.
* src/print_graph.c (print_graph): Work unconditionally.
* src/conflicts.c (log_resolution): Output only if verbose_flag.
2001-12-16 Marc Autret <[email protected]>
* src/output.c (actions_output): Fix. When we use %no-lines,
there is one less line per action.
2001-12-16 Marc Autret <[email protected]>
* src/bison.simple: Remove a useless #line directive.
s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.

(output_parser): Adjust, now takes care about the lines of a
output muscles.
Fix line numbering.

the output parser file name.
2001-12-15 Marc Autret <[email protected]>
* src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
2001-12-15 Marc Autret <[email protected]>
* src/output.c (output_gram): Keep track of the hairy one.
2001-12-15 Akim Demaille <[email protected]>
Make `make distcheck' work.
* lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
system.h which uses libgettext.h.
2001-12-15 Akim Demaille <[email protected]>
* src/nullable.c (set_nullable): Useless rules must be skipped,
otherwise, since we range over their symbols, we might look at a
nonterminal which no longer ``exists'', i.e., it is not counted in
`nvars', hence we overflow our arrays.
2001-12-15 Akim Demaille <[email protected]>
The header can also be produced directly, without any obstack!
Yahoo!
* src/files.c, src/files.h (defines_obstack): Remove.
(compute_header_macro): Global.
(defines_obstack_save): Remove.
* src/reader.c (parse_union_decl): No longer output to
defines_obstack: its content can be found in the `stype' muscle
anyway.
(output_token_translations): Merge into...
(symbols_output): this.
Rename as...
(symbols_save): this.
(reader): Adjust.
* src/output.c (header_output): New.
(output): Call it.
2001-12-15 Akim Demaille <[email protected]>
* src/reader.c (parse_union_decl): Instead of handling two obstack
simultaneously, use one to define the `stype' muscle, and use the
value of the latter to fill defines_obstack.
(copy_comment): Remove.
(copy_comment2): Work for a single obstack.
Rename as...
(copy_comment): this.
2001-12-15 Akim Demaille <[email protected]>
* src/lex.c, src/lex.h (xgetc): No longer static.
* src/reader.c (parse_union_decl): Revamp.
2001-12-15 Akim Demaille <[email protected]>
Still making progress in separating Bison into (i) input, (ii)
process, (iii) output: now we can directly output the parser file
without using table_obstack at all.
* src/files.c, src/files.h (table_obstack): Bye bye.
(parser_file_name): New.
* src/files.c (compute_output_file_names): Compute it.
* src/output.c (actions_output, output_parser)
(output_master_parser): To a file instead of an obstack.
2001-12-15 Akim Demaille <[email protected]>
Attach actions to rules, instead of pre-outputting them to
actions_obstack.
* src/gram.h (rule_t): action and action_line are new members.
* src/reader.c (symbol_list): Likewise.
(copy_action): Save the actions within the rule.
(packgram): Save them in rule_table.
* src/output.c (actions_output): New.
(output_parser): Use it on `%%actions'.
(output_rule_data): Don't free rule_table.
(output): Do it.
(prepare): Don't save the `action' muscle.
* src/bison.simple: s/%%action/%%actions/.
2001-12-15 Akim Demaille <[email protected]>
* src/reader.c (copy_action): When --yacc, don't append a `;'
to the user action: let it fail if lacking.
Suggested by Arnold Robbins and Tom Tromey.
2001-12-14 Akim Demaille <[email protected]>
* src/lex.c (literalchar): Simply return the char you decoded, non
longer mess around with obstacks and int pointers.
Adjust all callers.
2001-12-14 Akim Demaille <[email protected]>
* src/lex.c (literalchar): Don't escape the special characters,
just decode them, and keep them as char (before, eol was output as
the 2 char string `\n' etc.).
* src/output.c (output_rule_data): Use quotearg to output the
token strings.
2001-12-13 Paul Eggert <[email protected]>
* src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
Do not infringe on the global user namespace when using C++.
(YYFPRINTF, YYSTDERR): New macros, needed for the above.
All uses of `fprintf' and `stderr' changed.
* doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
2001-12-13 Akim Demaille <[email protected]>
The computation of nullable is broken: it doesn't handle empty
RHS's properly.
* tests/torture.at (GNU AWK Grammar): New.
* tests/sets.at (Nullable): New.
* src/nullable.c (set_nullable): Instead of blindly looping over
`ritems', loop over the rules, and then over their rhs's.
Work around Autotest bugs.
* src/warshall.c (bitmatrix_print): Don't use `+--+' as table
frame, because Autotest understand lines starting with a `+' as
traces from the shell. Then, they are not processed properly.
Admittedly an Autotest bug, but we don't have time to wait for
Autotest to catch up.
* tests/regression.at (Broken Closure): Adjust to the new table
frames.
Move to...
* tests/sets.at: here.
2001-12-13 Akim Demaille <[email protected]>
* src/closure.c (closure): Use nrules instead of playing tricks
with BITS_PER_WORD.
2001-12-13 Akim Demaille <[email protected]>
* src/print.c (print_actions): Output the handling of `$' as the
traces do: shifting the token EOF. Before EOF was treated as a
nonterminal.
* tests/regression.at: Adjust some tests.
* src/print_graph.c (print_core): Complete the set of items via
closure. The next-to-final and final states are still unsatisfying,
but that's to be addressed elsewhere.
No longer output the rule numbers, but do output the state number.
A single loop for the shifts + gotos is enough, but picked a
distinct color for each.
(print_graph): Initialize and finalize closure.
2001-12-13 Akim Demaille <[email protected]>
* src/reader.c (readgram): Remove dead code, an strip useless
braces.
(get_type): Remove, unused.
2001-12-12 Akim Demaille <[email protected]>
* src/complain.h, src/complain.c: Remove error_one_per_line, rely
on that of lib/error.c.
2001-12-12 Akim Demaille <[email protected]>
Some hosts don't like `/' in includes.
* src/system.h: Include libgettext.h without qualifying the path.
* src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
$(top_srcdir).
2001-12-11 Marc Autret <[email protected]>
* src/output.c (output_parser): Remove useless muscle.
2001-12-11 Marc Autret <[email protected]>
* src/bison.simple: Remove #line just before %%epilogue. It
is now handled in ...
* src/reader.c (read_additionnal_code): Add the output of a
#line for the epilogue.
2001-12-10 Marc Autret <[email protected]>
* src/reader.c (copy_definition): Re-use CPP-outed code which
replace precedent remove.
* src/bison.simple: Remove #line before %%prologue because
%%input-line is wrong at this time.
2001-12-10 Marc Autret <[email protected]>
* src/reader.c (symbols_output): Clean up.
* src/output.c (output_gram, output): Clean up.
2001-12-10 Akim Demaille <[email protected]>
* src/lalr.c (initialize_lookaheads): New. Extracted from...
* src/LR0.c (set_state_table): here.
* src/lalr.c (lalr): Call it.
2001-12-10 Akim Demaille <[email protected]>
* src/state.h (shifts): Remove the `number' member: shifts are
attached to state, hence no longer need to be labelled with a
state number.
2001-12-10 Akim Demaille <[email protected]>
Now that states have a complete set of members, the linked list of
shifts is useless: just fill directly the state's shifts member.
* src/state.h (shifts): Remove the `next' member.
* src/LR0.c (first_state, last_state): Remove.
Adjust the callers.
(augment_automaton): Don't look for the shifts that must be added
a shift on EOF: it is those of the state we looked for! But now,
since shifts are attached, it is no longer needed to looking
merely by its id: its number.
2001-12-10 Akim Demaille <[email protected]>
* src/LR0.c (augment_automaton): Better variable locality.
Remove an impossible branch: if there is a state corresponding to
the start symbol being shifted, then there is shift for the start
symbol from the initial state.
2001-12-10 Akim Demaille <[email protected]>
* src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
only when appropriate: when insert_start_shifting_state' is not
invoked.
* tests/regression.at (Rule Line Numbers): Adjust.
2001-12-10 Akim Demaille <[email protected]>
* src/LR0.c (augment_automaton): Now that all states have shifts,
merge the two cases addition shifts to the initial state.
2001-12-10 Akim Demaille <[email protected]>
* src/lalr.c (set_state_table): Move to...
* src/LR0.c: here.
* src/lalr.c (lalr): Don't call it...
* src/LR0.c (generate_states): do it.
* src/LR0.h (first_state): Remove, only the table is used.
2001-12-10 Akim Demaille <[email protected]>
* src/LR0.h (first_shift, first_reduction): Remove.
* src/lalr.c: Don't use first_shift: find shifts through the
states.
2001-12-10 Akim Demaille <[email protected]>
* src/LR0.c: Attach shifts to states as soon as they are
computed.
* src/lalr.c (set_state_table): Instead of assigning shifts to
state, just assert that the mapping was properly done.
2001-12-10 Akim Demaille <[email protected]>
* src/LR0.c (insert_start_shift): Rename as...
(insert_start_shifting_state): this.
(insert_eof_shifting_state, insert_accepting_state): New.
(augment_automaton): Adjust.
Better locality of the variables.
When looking if the start_symbol is shifted from the initial
state, using `while (... symbol != start_symbol ...)' sounds
better than `while (... symbol < start_symbol ...)': If fail
to see how the order between symbols could be relevant!
2001-12-10 Akim Demaille <[email protected]>
* src/getargs.h: Don't declare `spec_name_prefix' and
`spec_file_prefix', declared by src/files.h.
* src/files.c, src/files.h: Default for spec_name_prefix is "yy".
* src/muscle_tab.c (muscle_init): Default prefix to NULL.
* src/output.c (prepare): Adjust.
* src/reader.c (symbols_output): Likewise.
* src/vmsgetargs.c: Vaguely adjust, but who cares?
2001-12-10 Akim Demaille <[email protected]>
* src/muscle_tab.c (muscle_init): NULL is a better default than
`"0"'.
2001-12-10 Akim Demaille <[email protected]>
* src/reader.c (reader): Calling symbols_output once is enough.
2001-12-10 Akim Demaille <[email protected]>
Now that states have a complete set of members, the linked list of
reductions is useless: just fill directly the state's reductions
member.
* src/state.h (struct reductions): Remove member `number' and
`next'.
* src/LR0.c (first_reduction, last_reduction): Remove.
(save_reductions): Don't link the new reductions, store them in
this_state.
* src/lalr.c (set_state_table): No need to attach reductions to
states, it's already done.
* src/output.c (output_actions): No longer free the shifts, then
the reductions, then the states: free all the states and their
members.
2001-12-10 Akim Demaille <[email protected]>
* src/options.c (OPTN, DRTV, BOTH): New.
(option_table): Use them.
* src/muscle_tab.c: Don't include xalloc.h and string.h: that's
the job of system.h.
* src/options.c: Don't include stdio.h and xalloc.h for the same
reasons.
2001-12-10 Akim Demaille <[email protected]>
* src/output.c (output, prepare): Make sure the values of the
muscles `action' and `prologue' are 0-terminated.
2001-12-10 Akim Demaille <[email protected]>
Clean up GCC warnings.
* src/reader.c (copy_action): `buf' is not used.
(parse_skel_decl): Be static.
* src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
* src/options.h (create_long_option_table): Have a real prototype.
* lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
(hash_delete_at): Return const void *.
Adjust casts to preserve the const.
2001-12-10 Akim Demaille <[email protected]>
* configure.in: Require 2.52g.
M4 is not needed, but AUTOM4TE is.
* m4/m4.m4: Remove.
* tests/Makefile.am: Adjust.
2001-12-10 Akim Demaille <[email protected]>
One structure for states is enough, even though theoretically
there are LR(0) states and LALR(1) states.
* src/lalr.h (state_t): Remove.
(state_table): Be state_t **, not state_t *.
* src/state.h (core, CORE_ALLOC): Rename as...
(state_t, STATE_ALLOC): this.
Add the LALR(1) members: shifts, reductions, errs.
* src/LR0.c (state_table): Rename as...
(state_hash): this, to avoid name clashes with the global
`state_table'.
* src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
* src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
2001-12-10 Akim Demaille <[email protected]>
Bison dumps core on bash.y.
Reported by Pascal Bart.
* src/warshall.c (bitmatrix_print): New.
(TC): Use it.
When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
j must be the outer loop.
* tests/regression.at (Broken Closure): New.
2001-12-05 Akim Demaille <[email protected]>
* tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
its argument.
Reported by Peter H�morsk�.
2001-12-05 Akim Demaille <[email protected]>
* src/conflicts.c (err_table): Remove.
(resolve_sr_conflict): Adjust.
* src/lalr.h (state_t.reduction_table, state_t.shift_table):
Rename as...
(state_t.reductions, state_t.shifts): this.
2001-12-05 Akim Demaille <[email protected]>
* src/reduce.c (reduce_grammar_tables): No longer disable the
removal of useless rules via CPP but via `if (0)', so that the
compiler still check the code is valid.
For instance, it should have noticed `rline' no longer exists: use
the `line' member of rule_t.
* src/gram.c (dummy, rline): Remove, unused.
2001-12-05 Akim Demaille <[email protected]>
* src/output.c (pack_vector): Use assert, not berror.
* src/main.c (berror): Remove, unused.
2001-12-05 Akim Demaille <[email protected]>
New experimental feature: if --verbose --trace output all the
items of a state, not only its kernel.
* src/print.c (print_core): If `trace_flag', then invoke closure
before outputting the items of the state (print_core is no longer
a correct name them).
(print_results): Invoke new_closure/free_closure if needed.
2001-12-05 Akim Demaille <[email protected]>
* src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
* src/closure.c, src/closure.h (itemsetsize): Rename as...
(nitemset): for consistency with the rest of the project.
2001-12-05 Akim Demaille <[email protected]>

(closure): Use it for printing input and output.
2001-12-05 Akim Demaille <[email protected]>

indexed by nonterminals.
2001-12-05 Akim Demaille <[email protected]>
* src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
what it was!).

2001-12-05 Akim Demaille <[email protected]>
* src/output.c (action_row): De-obfuscate
using the good o' techniques: arrays not pointers, variable
locality, BITISSET, RESETBIT etc.
2001-12-05 Akim Demaille <[email protected]>
Pessimize the code to simplify it: from now on, all the states
have a valid SHIFTS, which NSHIFTS is possibly 0.
* src/LR0.c (shifts_new): Be global and move to..
* src/state.c, src/state.h: here.
* src/conflicts, src/lalr.c, src/output.c, src/print.c,
* src/print_graph: Adjust.
2001-12-05 Akim Demaille <[email protected]>
* src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
* src/conflicts.c: Use it.
Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
incorrectly ``simplified''.
2001-12-05 Akim Demaille <[email protected]>
* src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
using the good o' techniques: arrays not pointers, variable
locality, BITISSET, RESETBIT etc.
2001-12-05 Akim Demaille <[email protected]>
* src/state.h (SHIFT_SYMBOL): New.
* src/conflicts.c: Use it to deobfuscate.
2001-12-05 Akim Demaille <[email protected]>

arrays not pointers, variable locality, BITISSET.
2001-12-05 Akim Demaille <[email protected]>

Use BITISSET.
2001-12-05 Akim Demaille <[email protected]>

2001-12-05 Akim Demaille <[email protected]>
* src/LR0.c (augment_automaton): Formatting changes.
Better variable locality.
2001-12-05 Akim Demaille <[email protected]>

(transpose): Use it.
Use arrays instead of pointers.
2001-12-05 Akim Demaille <[email protected]>
* src/lalr.c (maxrhs): Move to...
* src/gram.c, src/gram.h (ritem_longest_rhs): here.
* src/lalr.c (build_relations): Adjust.
2001-12-05 Akim Demaille <[email protected]>
* src/lalr.c (transpose): Free the memory allocated to the
argument, as it is replaced by the results by the unique caller.
(build_relations): Merely invoke transpose: it handles the memory
deallocation.
Improve variable locality.
Avoid variables used as mere abbreviations.
(compute_lookaheads): Use arrays instead of pointers.
2001-12-05 Akim Demaille <[email protected]>

* src/lalr.c (traverse): Use arrays instead of pointers.
2001-12-05 Akim Demaille <[email protected]>
* src/nullable.c (set_nullable): Use a for loop to de-obfuscate
the handling of squeue.
`symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
2001-12-05 Akim Demaille <[email protected]>
Because useless nonterminals are now kept alive (instead of being
`destroyed'), we now sometimes examine them, and store information
related to them. Hence we need to know their number, and adjust
memory allocations.
* src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
static.
* src/LR0.c (allocate_itemsets): The memory allocated to
`symbol_count' was used for two different purpose: once to count
the number of occurrences of each symbol, and later reassigned to
`shift_symbol', containing the symbol that can be shifted from a
given state.
Deobfuscate, i.e., allocate, use and free `symbol_count' here
only, and...
(new_itemsets): Allocate `shift_symbol' here.
(allocate_itemsets): symbol_count includes useless nonterminals.
Make room for them.
(free_storage): Use `free', not `XFREE', for pointers that cannot
be null.
2001-12-05 Akim Demaille <[email protected]>
* src/nullable.c (set_nullable): Deobfuscate the handling of

that can't handle compilation units with variables only).
* src/reduce.c (dump_grammar): Use it to trace the construction of
ritem.
2001-12-04 Paul Eggert <[email protected]>
* src/bison.simple (union yyalloc): Change member names
to be the same as the stack names.
(yyparse): yyptr is now union yyalloc *, not char *.
(YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
and may generate better code on some machines.
(yystpcpy): Use prototype if __STDC__ is defined, not just
if __cplusplus is defined.
2001-11-30 Akim Demaille <[email protected]>
* configure.in (WARNING_CFLAGS): Add -Werror when possible.
(CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
Gettext doesn't compile cleanly, and dies with -Werror.
* src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
Include WARNING_CFLAGS here.
* lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
before being defined.
2001-11-27 Paul Eggert <[email protected]>
* lib/quotearg.h (quotearg_n, quotearg_n_style):
First arg is int, not unsigned.
* lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
(SIZE_MAX, UINT_MAX): New macros.
(quotearg_n_options): Abort if N is negative.
Avoid overflow check on hosts where size_t is 64 bits and int
is 32 bits, as overflow is impossible there.
Fix off-by-one typo that caused unnecessary reallocation.
2001-11-29 Paul Eggert <[email protected]>
Name space cleanup in generated parser.
* doc/bison.texinfo (Bison Parser): Discuss system headers
and their effect on the user name space.
* src/bison.simple:
(YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
(YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
on user names when possible.
(YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
Simplify test for whather <alloca.h> exists.
(<stdlib.h>): Include if we will use malloc, and if standard C or C++.
(<stdio.h>): Include if YYDEBUG.
(yymemcpy): Renamed from __yy_memcpy. Do not define unless
! defined (yyoverflow) && ! defined (yymemcpy).
(yymemcpy, yyparse): Rename local variables as needed so that
they all begin with 'yy'.
(yystrlen, yystpcpy): New functions.
(YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
All uses changed.
(yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
instead of relying on string.h functions. Use YYSTACK_ALLOC
and YYSTACK_FREE instead of malloc and free.
2001-11-30 Akim Demaille <[email protected]>
* src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
before their first uses.
(YYBISON, YYPURE): Move to the top of the output.
2001-11-30 Akim Demaille <[email protected]>
* tests/reduce.at (Useless Nonterminals): Fix.
2001-11-30 Akim Demaille <[email protected]>
* src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
if body instead of `;' to pacify GCC's warnings.
2001-11-30 Akim Demaille <[email protected]>
Instead of mapping the LHS of unused rules to -1, keep the LHS
valid, but flag the rules as invalid.
* src/gram.h (rule_t): `useful' is a new member.
* src/print.c (print_grammar): Adjust.
* src/derives.c (set_derives): Likewise.
* src/reader.c (packgram, reduce_output): Likewise.
* src/reduce.c (reduce_grammar_tables): Likewise.

(Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
2001-11-30 Akim Demaille <[email protected]>

2001-11-30 Akim Demaille <[email protected]>
* src/reduce.c: Various comment/formatting changes.

(YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
(YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
New macros.
(union yyalloc): New type.
(__yy_memcpy): Last arg is size_t, not unsigned int, to remove
an arbitrary restriction on hosts where size_t is wider than int.
(yyparse): Don't dump core if alloca or malloc fails; instead, report
a parser stack overflow. Allocate just one block of memory for all
three stacks, instead of allocating three blocks; this typically is
faster and reduces fragmentation.
Do not limit the number of items in the stack to a value that fits
in 'int', as this is an arbitrary limit on hosts with 64-bit
size_t and 32-bit int.
2001-11-29 Marc Autret <[email protected]>
* tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

then bits in words, loop over bits in array.
2001-11-28 Akim Demaille <[email protected]>
* src/closure.c (closure): No longer optimize the special case
where all the bits of `ruleset[r]' are set to 0, to make the code
clearer.
2001-11-28 Akim Demaille <[email protected]>
* src/closure.c (closure): `r' and `c' are new variables, used to
de-obfuscate accesses to RULESET and CORE.
2001-11-28 Akim Demaille <[email protected]>
* src/reduce.c (reduce_print): Use ngettext.
(dump_grammar): Improve the trace accuracy.
2001-11-28 Akim Demaille <[email protected]>
* src/reduce.c (dump_grammar): Don't translate trace messages.
2001-11-28 Akim Demaille <[email protected]>
* tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
* src/reduce.c (reduce_grammar_tables): Do not free useless tags,
as all tags are free'ed afterwards.

* tests/regression.m4: New file.
Include the core of the sample provided by Piotr Gackiewicz.
* src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
properly.
2000-10-04 Akim Demaille <[email protected]>
* src/reader.c (parse_expect_decl): Keep `count' within the size
of `buffer'.
From Neil Booth.
2000-10-02 Paul Eggert <[email protected]>
* bison.s1 (yyparse): Assign the default value
unconditionally, to avoid a GCC warning and make the parser a
tad smaller.
2000-10-02 Akim Demaille <[email protected]>
* src/getargs.c (getargs): Don't dump `--help' on unrecognized
options.
2000-10-02 Akim Demaille <[email protected]>
* src/derives.c, src/print.c, src/reduce.c: To ease the
translation, move some `\n' out of the translated strings.
2000-10-02 Akim Demaille <[email protected]>
The location tracking mechanism is precious for parse error
messages. Nevertheless, it is enabled only when `@n' is used in
the grammar, which is a different issue (you can use it in error
message, but not in the grammar per se). Therefore, there should
be another means to enable it.
* src/getargs.c (getargs): Support `--locations'.
(usage): Report it.
* src/getargs.h (locationsflag): Export it.
* src/lex.c (percent_table): Support `%locations'.
* src/reader.c (yylsp_needed): Remove this variable, now replaced
with `locationsflag'.
* doc/bison.texinfo: Document `--locations' and `%locations'.
Sort the options.
* tests/calc.m4: Test it.
For regularity of the names, replace each
(nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
(no_lineflag, token_tableflag, rawflag, no_parserflag): this.
In addition replace each `flag' with `_flag'.
2000-10-02 Akim Demaille <[email protected]>
Also test parse error messages, including with YYERROR_VERBOSE.
* tests/calc.m4 (calc.y): Add support for `exp = exp' (non
associative).
Use it to check the computations.
Use it to check `nonassoc' is honored.
(AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
`--yyerror-verbose'.
(_AT_CHECK_CALC): Adjust to this option.
(_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2000-10-02 Akim Demaille <[email protected]>
Test also `--verbose', `--defines' and `--name-prefix'. Testing
the latter demonstrates a flaw in the handling of non debugging
parsers introduced by myself on 2000-03-16: `#define yydebug 0'
was used in order to simplify:
#if YYDEBUG
if (yydebug)
{
...
}
#endif
into
if (yydebug)
{
...
}
unfortunately this leads to a CPP conflict when
`--name-prefix=foo' is used since it produces `#define yydebug
foodebug'.
* src/bison.s1 [!YYDEBUG]: Do not define yydebug.
(YYDPRINTF): New macro.
Spread its use.
* tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
the bison options.
Also test `--verbose', `--defines' and `--name-prefix'.
2000-10-02 Akim Demaille <[email protected]>
Improve the readability of the produced parsers.
* src/bison.s1: Formatting changes.
Improve the comment related to the `$' mark.
(yydefault): Don't fall through to `yyresume': `goto' there.
* src/output.c (output_parser): When the `$' is met, skip the end
of its line.
New variable, `number_of_dollar_signs', to check there's exactly
one `$' in the parser skeleton.
2000-10-02 Akim Demaille <[email protected]>
* lib/xstrdup.c: New file, from the fileutils.
* src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
(parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
instead of strlen + xmalloc + strcpy.
* src/symtab.c (copys): Remove, use xstrdup instead.
2000-10-02 Akim Demaille <[email protected]>
* src/gram.h (associativity): New enum type which replaces the
former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
`right_assoc', `left_assoc' and `non_assoc'.
Adjust all dependencies.
* src/reader.c: Formatting changes.
(LTYPESTR): Don't define it, use it as a literal in
`reader_output_yylsp'.
* src/symtab.h (symbol_class): New enum type which replaces the
former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
`sunknown', `stoken and `snterm'.
2000-10-02 Akim Demaille <[email protected]>
* src/getargs.c (fixed_outfiles): Rename as...
(yaccflag): for consistency and accuracy.
Adjust dependencies.
2000-10-02 Akim Demaille <[email protected]>
Use the more standard files `xalloc.h' and `xmalloc.c' instead of
Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
difficult and introduced a lot of core dump. It turns out that
Bison used an implementation of `xmalloc' based on `calloc', and
at various places it does depend upon the initialization to 0. I
have not tried to isolate the pertinent places, and all the former
calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
someone should address this issue.
* src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
* lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
files.
Adjust dependencies.
* src/warshall.h: New file.
Propagate.
2000-10-02 Akim Demaille <[email protected]>
Various anti-`extern in *.c' changes.

2000-10-02 Akim Demaille <[email protected]>
* src/output.c (token_actions): Introduce a temporary array,
YYDEFACT, that makes it possible for this function to use
output_short_table.
2000-10-02 Akim Demaille <[email protected]>
`user_toknums' is output as a `short[]' in `output.c', while it is
defined as a `int[]' in `reader.c'. For consistency with the
other output tables, `user_toknums' is now defined as a table of
shorts.

table.
Adjust dependencies.
Factor the short table outputs.

* src/acconfig.h: Don't protect config.h against multiple
inclusion.
Don't define PARAMS.
* src/system.h: Define PARAMS.
Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
purpose of config.h. system.h must not try to fix wrong
definitions in config.h.

Change the handling of @s so that they behave exactly like $s.
There is now a pseudo variable @$ (readble and writable), location
of the lhs of the rule (by default ranging from the location of
the first symbol of the rhs, to the location of the last symbol,
or, if the rhs is empty, YYLLOC).
* src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
yyval.
