Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
|
|
GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
|
|
lookahead symbol, and which sets yychar in parser actions) and it
|
|
disagreed with the Bison documentation. This should fix the bug
|
|
reported by Andrew Walrond in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
|
|
|
|
* data/yacc.c (YYTRANSLATE): Don't check for negative argument,
|
|
as the caller now does that.
|
|
(yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
|
|
(YYEMPTY): Parenthesize right hand side, since others use it.
|
|
(yyparse): Don't assume that our generated code is the only code
|
|
that sets yychar.
|
|
|
|
2002-12-13 Paul Eggert <[email protected]>
|
|
|

|
|
as an alias for bison y.
|
|
|
|
* po/LINGUAS: Add da.
|
|
|
|
* src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
|
|
problem with latest <getopt.h>.

|
|
|
|
* doc/fdl.texi: Upgrade to 1.2.
|

Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001929.html>.

|
|
locations are requested.

|
|
|
|
Remove unportable casts and storage allocation tricks.
|
|
While we're at it, remove almost all casts, since they
|
|
usually aren't needed and are a sign of trouble.
|
|
|
|
* configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
|
|
|
|
* src/derives.c (derives_compute): Do not subtract NTOKENS from
|
|
the pointer DSET returned by malloc; this isn't portable.
|
|
Instead, always use DSET[i - NTOKENS] rather than DSET[i].
|
|
Similarly for DERIVES.
|
|
* src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
|
|
* src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
|
|
* src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
|
|
|
|
* src/derives.c (derives_compute): Do not bother invoking
|
|
int_of_rule_number, since rule numbers are integers.
|
|
|
|
* src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
|
|
rather than XMALLOC (char, N).
|
|
|
|
* src/files.c (filename_split): Rewrite to avoid cast.
|
|
|
|
* src/gram.h (symbol_number_as_item_number,
|
|
item_number_as_symbol_number, rule_number_as_item_number,
|
|
item_number_as_rule_number):
|
|
Now inline functions rather than macros, to avoid casts.
|
|
* src/state.h (state_number_as_int): Likewise.
|
|
* src/tables.c (state_number_to_vector_number,
|
|
symbol_number_to_vector_number): Likewise.
|
|
|
|
* src/gram.h (int_of_rule_number): Remove; no longer used.
|
|
|
|
* src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
|
|
since the resulting storage is always stored into.
|
|
|
|
* src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
|
|
where it's needed.
|
|
|
|
* src/muscle_tab.c (muscle_m4_output):
|
|
Now inline. Return bool, not int.
|
|
* src/state.c (state_compare): Likewise.

* src/symtab.c (symbol_check_defined,
|
|
symbol_check_alias_consistency, symbol_pack, symbol_translation,

|
|
Likewise.
|
|
* src/uniqstr.c (uniqstr_print): Likewise.
|
|
* src/muscle_tab.c (muscle_m4_output_processor):
|
|
New function, to avoid casts.
|
|
* src/state.c (state_comparator, stage_hasher): Likewise.
|
|
* src/symtab.c (symbol_check_defined_processor,
|
|
symbol_check_alias_consistency_processor, symbol_pack_processor,
|
|
symbol_translation_processor, hash_symbol_comparator,
|
|
hash_symbol_hasher): Likewise.
|
|
* src/uniqstr.c (uniqstr_print_processor): Likewise.
|
|
* src/muscle_tab.c (muscles_m4_output):
|
|
Use new functions instead of casting old functions unportably.
|
|
* src/state.c (state_hash_new): Likewise.
|
|
* src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
|
|
symbols_token_translations_init):
|
|
Likewise.
|
|
* src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
|
|
|
|
* src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
|
|
var instead of casting to long, to avoid casts.
|
|
(prepare_states): Use MALLOC rather than alloca, so that we don't
|
|
have to worry about alloca.
|
|
* src/state.c (state_hash_lookup): Likewise.
|
|
|
|
* src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
|
|
local var instead of casting to unsigned char, to avoid casts.
|
|
|
|
* src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
|
|
STATE_ALLOC): Remove.
|
|
(transitions_new, errs_new, reductions_new, state_new): Use malloc
|
|
rather than calloc, and use offsetof to avoid allocating slightly
|
|
too much storage.
|
|
(state_new): Initialize all members.
|
|
|
|
* src/state.c (state_hash): Use unsigned accumulator, not signed.
|
|
|
|
* src/symtab.c (symbol_free): Remove; unused.
|
|
(symbol_get): Remove cast in lhs of assignment.
|
|
(symbols_do): Now static. Accept generic arguments, not
|
|
hashing-related ones.
|
|
|
|
* src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
|
|
(symbol_processor): Remove.
|
|
(symbols_do): Remove decl; now static.
|
|
|
|

|
|
(<inttypes.>, <stdint.h>): Include if available.
|
|
(uintptr_t): New type, if system lacks it.
|
|
(CALLOC, MALLOC, REALLOC): New macros.
|
|
All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
|
|
new macros.
|
|
|
|
* src/tables.c (table_size): Now int, to pacify GCC.
|

|
|
|

|
|
|
|
* src/vcg_defaults.h (G_CMAX): Now INT_MAX.
|
|

|
|
|
|

|
|
|
|
Change identifier spellings to avoid collisions with names
|
|
that are reserved by POSIX.
|
|
|
|
Don't use names ending in _t, since POSIX reserves them.
|
|
For consistency, remove _e and _s endings -- they're weren't
|
|
needed to remove ambiguity. All uses changed.
|
|
* src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
|
|
turn was just renamed from struniq_t.
|

Don't include <errno.h> in the mainstream code, since it

likewise for "STRUNIQ" and "UNIQSTR".
|
|
* src/uniqstr.c: Renamed from src/struniq.c.

for consistency with other names.

|
|
|
|
|
|
Sort include-file uses.
|
|
|
|
Reorder all include files under src to be in the order "system.h".
|
|
then the ../lib include files in angle brackets (alphabetized),
|
|
then the . include files in double-quotes (alphabetized). Fix
|
|
dependency breakages encountered in this process, as follows:
|
|
* src/closure.h, src/derives.h, src/state.h: Include "gram.h".
|
|
* src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
|
|
* src/state.h: Include "symtab.h".
|
|
|
|
2002-12-08 Paul Eggert <[email protected]>
|
|
|
|
* data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
|
|
since this causes problems when __file__ contains character
|
|
sequences like "@" that are treated specially by src/scan-skel.l.
|
|
Instead, just use the file's basename. This fixes the bug
|
|
reported by Martin Mokrejs in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001945.html>.

|
|
|
|
Add support for rules that do not have trailing semicolons, as
|
|
POSIX requires. Improve the quality of locations in Bison
|
|
diagnostics.
|
|
|
|
* src/location.c: Include <quotearg.h>.
|
|
(empty_location): Now const.
|
|
(location_print): New function. Follow the recommendation of the
|
|
GNU Coding Standards for locations that span file boundaries.
|
|
* src/location.h: Do not include <quotearg.h>; no longer needed.
|
|
(boundary): New type.
|
|
(location_t): Use it. This allows locations to span file boundaries.
|
|
All member uses changed: file -> start.file or end.file (as needed),
|
|
first_line -> start.line, first_column -> start.column,
|
|
last_line -> end.line, last_column -> end.column.
|
|
(equal_boundaries): New function.
|
|
(LOCATION_RESET, LOCATION_STEP): Remove.
|
|
(LOCATION_PRINT): Remove. All callers changed to use location_print.
|
|
(empty_location): Now const.
|
|
(location_print): New decl.
|
|
* src/parse-gram.y (lloc_default): New function, which handles
|
|
empty locations more accurately.
|
|
(YYLLOC_DEFAULT): Use it.
|
|
(%token COLON): Remove.
|
|
(%token ID_COLON): New token.
|
|
(rules): Use it.
|
|
(declarations, rules): Remove trailing semicolon.

(declaration, rules_or_grammar_declaration):
|
|
Allow empty (";") declaration.
|
|
(symbol_def): Remove empty actions; no longer needed.
|
|
(rules_or_grammar_declaration): Remove trailing semicolon.
|
|
(semi_colon.opt): Remove.
|
|
* src/reader.h: Include location.h.
|
|
(scanner_cursor): New decl.
|
|
* src/reduce.c (nonterminals_reduce): Use warn_at rather than
|
|
rolling our own.
|
|
* src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
|
|
of *loc.
|
|
(STEP): Remove. No longer needed, now that adjust_location does
|
|
the work. All uses removed.
|
|
(scanner_cursor): New var.
|
|
(adjust_location): Renamed from extend_location. It now sets
|
|
*loc and adjusts the scanner cursor. All uses changed.
|
|
Don't bother testing for CR.
|
|
(handle_syncline): Remove location arg; now updates scanner cursor.
|
|
All callers changed.
|
|
(unexpected_end_of_file): Now accepts start boundary of token or
|
|
comment, not location. All callers changed. Update scanner cursor,
|
|
not the location.
|
|
(SC_AFTER_IDENTIFIER): New state.
|
|
(context_state): Renamed from c_context. All uses changed.
|
|
(id_loc, code_start, token_start): New local vars.
|
|
(<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
|
|
processing of Yacc white space and equivalents here.
|
|
(<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
|
|
instead of returning ID immediately, since we need to search for
|
|
a subsequent colon.
|
|
(<INITIAL>"'", "\""): Save token_start.
|
|
(<INITIAL>"%{", "{", "%%"): Save code_start.
|
|
(<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
|
|
(<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
|
|
BEGIN context_state at end, not INITIAL.
|
|
(<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
|
|
<SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
|
|
Return correct token start.
|
|
(<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
|
|
the start of a character, string or multiline comment is found.
|
|
* tests/conflicts.at (S/R in initial, Defaulted Conflicted
|
|
Reduction): Adjust reported locations to match the more-precise
|
|
results now expected.
|
|
* tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
|
|
* tests/reduce.at (Useless Rules, Reduced Automaton,
|
|
Underivable Rules): Likewise.
|
|
* tests/regression.at (Invalid inputs): No longer `expecting ";"
|
|
or "|"' now that so many other tokens are allowed by the new grammar.
|
|
|
|
* src/complain.h (current_file): Remove duplicate decl;
|
|
current_file is now owned by files.h.
|
|
* src/complain.c, src/scan-gram.l: Include files.h.
|
|
|
|

|
|
|
|
* data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
|
|
promotes to int; it might be unsigned int.
|
|
* data/yacc.c (yy_reduce_print): Likewise.
|
|
|
|
* doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
|
|
be #defined in the prologue, not in the Bison declarations.
|
|
This fixes Debian Bug 102878, reported by Shaul Karl.
|

|
|
2002-12-02 Paul Eggert <[email protected]>
|
|
|
|
* configure.ac (AC_REPLACE_FUNCS): Add strtoul.
|
|
* lib/strtoul.c: New file, from gnulib.
|
|
This fixes a porting bug reported by Peter Klein in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001944.html>.
|
|
|
|
2002-11-30 Paul Eggert <[email protected]>
|
|
|
|
* src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
|
|
and put only a forward declaration in the prologue. This is for
|
|
consistency with the other scanner helper functions.
|
|
|
|
Type clashes now generate warnings, not errors, since it
|
|
appears that POSIX may allow some grammars with type clashes.
|
|
* src/reader.c (grammar_current_rule_check): Warn about
|
|
type clashes instead of complaining.
|
|
* tests/input.at (Type Clashes): Expect warnings, not complaints.
|
|
|
|
Add Yacc library, since POSIX requires it.
|
|
* doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
|
|
* lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
|
|
* lib/main.c, lib/yyerror.c: New files.
|
|
|
|
gram_error can be static; it need not be extern.
|
|
* src/reader.h (gram_error): Remove decl.
|
|
* src/parse-gram.y (gram_error): Now static. Add static decl.
|
|
(print_token_value): Omit parameter names from forward decl,
|
|
for consistency.
|
|
|
|
2002-11-29 Paul Eggert <[email protected]>
|
|
|
|
* doc/bison.texinfo: Emphasize that yylex and yyerror must
|
|
be declared before being used. E.g., one should typically
|
|
declare them in the prologue. Use GNU coding style in examples.
|
|
Put "const" consistently after the type it modifies. Mention
|
|
that C99 supports "inline". Mention that yyerror traditionally
|
|
returns "int".
|
|
|
|
%parse-param and %lex-param now take just one argument, the
|
|
declaration; the argument name is deduced from the declaration.
|
|
|
|
* doc/bison.texinfo (Parser Function, Pure Calling, Error
|
|
Reporting, Table of Symbols): Document this.
|
|
* src/parse-gram.y (add_param): New function.
|
|
(COMMA): Remove.
|
|
(declaration): Implement new rule for %parse-param and %lex-param.
|
|
* src/scan-gram.l: "," now elicits a warning, rather than being
|
|
a token; this is more compatible with byacc.
|
|
* tests/calc.at (Simple LALR Calculator): Adopt new convention.
|
|
|
|
2002-11-27 Paul Eggert <[email protected]>
|
|
|
|
Rename identifiers to avoid real and potential collisions.
|
|
|
|
* data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
|
|
to avoid collision with lex macro described by Bruce Lilly in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001929.html>.
|
|
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
|
|
* doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
|
|
* src/parse-gram.y (print_token_value): Renamed from yyprint.
|
|
All uses changed.
|
|
(YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
|
|
The name "yycontrol" violates the name space rules, and this stuff
|
|
wasn't being used anyway.
|
|
(input): Remove action; this stuff wasn't being used.
|
|
(gram_error): Rename local variable yylloc -> loc.
|
|
* src/reader.h (struct gram_control_s, gram_control_t): Remove.
|
|
(YY_DECL): Don't use "yy" at start of local variables.
|
|
All uses changed, e.g., yylloc -> loc.
|
|
* src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
|
|
(STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
|
|
(STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
|
|
(STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
|
|
|
|
* src/parse-gram.y (gram_error): loc is now const *.
|
|
* src/reader.h (gram_error): Likewise.
|
|
|
|
2002-11-24 Paul Eggert <[email protected]>
|
|
|
|
Version 1.75c.
|
|
|
|
* tests/actions.at (Actions after errors): Use an output format
|
|
more similar to that of the Printers and Destructors test.
|
|
Test the position of the ';' token too.
|
|
(Printers and Destructors): Likewise.
|
|
(Printers and Destructors: %glr-parser): Remove for now, to avoid
|
|
unnecessarily alarming people when the test fails.
|
|
|
|
* data/yacc.c (yyerrlab1): Move this label down, so that the
|
|
parser does not discard the lookahead token if the user code
|
|
invokes YYERROR. This change is required for POSIX conformance.
|
|
|
|
* lib/error.c: Sync with gnulib.
|
|
|
|
2002-11-22 Paul Eggert <[email protected]>

|
|
|
|
2002-11-20 Paul Eggert <[email protected]>
|
|
|
|
Avoid use of <assert.h>, as the GNU Coding Standards hint that one
|
|
should use `if (! x) abort ();' rather than `assert (x);', and
|
|
anyway it's one less thing to worry about configuring.
|
|
|
|
* data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
|
|
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
|
|
and replace all instances of assert with abort.
|
|
* tests/calc.at (_AT_DATA_CALC_Y): Likewise.

|
|

yyresolveAction, yyprocessOneStack): Use abort rather than assert.

|
|
|
|
* lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.

rather than assert.
|
|

|
* src/struniq.c (struniq_assert): Now returns void, and aborts
|
|
if the assertion is false.
|
|
(struniq_assert_p): Remove.
|
|
* src/struniq.h: Likewise.
|
|
|
|
2002-11-18 Paul Eggert <[email protected]>
|
|
|
|
* data/glr.c (yygetLRActions): Replace `yyindex' with
|
|
`yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
|
|
This fixes the regression with Sun ONE Studio 7 cc that I reported in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001892.html>.
|
|
|
|
2002-11-18 Akim Demaille <[email protected]>
|
|
|
|
* doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
|
|
space.
|
|
From Tim Van Holder.
|
|
|
|
2002-11-17 Paul Eggert <[email protected]>
|
|
|
|
Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
|
|
to "SyntaxError" for consistency with my 2002-11-15 change.
|
|
|
|
* data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
|
|
not define to {}, since this breaks the common use of `YYDPRINTF
|
|
((...));' if a single statement is desired (e.g. before `else').
|
|
Work around GCC warnings by surrounding corresponding calls with
|
|
{} if needed.
|
|
(yyhasResolvedValue): Remove unused function.
|
|
(yymergeOptionSets, yyresolvStack): Use `continue;' for empty
|
|
loop body.
|
|
(yyreportSyntaxError): Renamed from yyreportParseError.
|
|
(yyrecoverSyntaxError): Renamed from yyrecoverParseError.
|
|
All uses changed.
|
|
* tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
|
|
extern when possible. Remove unused initializations.
|
|
|
|
2002-11-16 Akim Demaille <[email protected]>
|
|
|
|
Augment the similarity between GLR and LALR traces.
|
|
|
|
* data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
|
|
(YY_REDUCE_PRINT): New.
|
|
(yyparse): Use them.
|
|
* data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
|
|
YYDPRINT here.
|
|
(yyglrReduce, yyrecoverParseError, yyparse): Don't report the
|
|
state reached after the reduction/recovery, since...
|
|
(yyparse, yyprocessOneStack): Report the state we are entering in.
|
|
|
|
2002-11-16 Akim Demaille <[email protected]>
|
|
|
|
* src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
|
|
Add support for --trace=skeleton.
|
|
* src/scan-skel.l: %option debug.
|
|
Scan strings of non-@ or \n instead of character by character.
|
|
(scan_skel): Handle trace_skeleton.
|
|
(QPUTS): New.
|
|
(@output_parser_name@, @output_header_name@): ``Restore'' their
|
|
support (used to be M4 macros).
|
|
* data/yacc.c: Quote larger chunks, a la glr.c.
|
|
* data/lalr1.cc: Likewise.
|
|
The header guards are no longer available, so use some other
|
|
string than `YYLSP_NEEDED'.
|
|
|
|
2002-11-16 Akim Demaille <[email protected]>
|
|
|
|
Make the ``Printers and Destructors'' test more verbose, taking
|
|
`yacc.c''s behavior as (possibly wrong) reference.
|
|
|
|
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
|
|
instead of fprint on stdout.
|
|
Set and report the last_line of the symbols.
|
|
Consistently display values and locations.
|
|
|
|
2002-11-16 Paul Eggert <[email protected]>
|
|
|
|
* data/yacc.c: Avoid over-quoting of __line__ and __file__.
|
|
|
|
2002-11-15 Paul Eggert <[email protected]>
|
|
|
|
* tests/actions.at (Actions after errors): New test case.
|
|
|
|
* data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
|
|
src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
|
|
tests/action.at, tests/calc.at, tests/conflicts.at,
|
|
tests/cxx-type.at, tests/regression.at:
|
|
"parse error" -> "syntax error" for POSIX compatibility.
|
|
"parsing stack overflow..." -> "parser stack overflow" so
|
|
that code matches Bison documentation.
|
|
|
|
2002-11-15 Akim Demaille <[email protected]>
|
|
|
|
* src/parse-gram.y (declaration): Have %parse-param and %lex-param
|
|
take two BRACED_CODE, not two string_content.
|
|
Free the scanner's obstack when we are done.
|
|
(code_content): New.
|
|
* tests/calc.at: Adjust.
|
|
* doc/bison.texinfo: Adjust.
|
|
Also, make sure to include the `,' for these declarations.
|
|
|
|
2002-11-15 Tim Van Holder <[email protected]>
|
|
|
|
* m4/prereq.m4: Removed the commented jm_PREREQ_HASH
|
|
definition; avoids potential autoreconf problems.
|
|
|
|
2002-11-15 Akim Demaille <[email protected]>
|
|
|
|
Always check the value returned by yyparse.
|
|
|
|
* tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
|
|
returned by yyparse.
|
|
(_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
|
|
Adjust calls.
|
|
* tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
|
|
returned by yyparse.
|
|
|
|
2002-11-14 Paul Hilfinger <[email protected]>
|
|
|
|
* data/glr.c (yyFail): Always set yyerrflag. Corrects regression
|
|
on input.at test.
|
|
|
|
2002-11-14 Paul Eggert <[email protected]>
|
|
|
|
* src/output.c (output_skeleton): Call xfopen instead of
|
|
duplicating xfopen's body.
|
|
|
|
Fix bugs reported by Nelson H. F. Beebe in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
|
|
|
|
* tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
|
|
"$CC -E foo.h" is allowed, as this doesn't work with the Portland
|
|
Group compiler. Instead, use "$CC -E bar.c". Include the .h
|
|
file twice in the grammar, as an extra check.
|
|
|
|
* tests/input.at (Torturing the Scanner): Surround the
|
|
backslash-newline tests with "#if 0", to make it less likely that
|
|
we'll run into compiler bugs. Bring back solitary \ inside
|
|
comment, but add a closing comment to work around HP C bug. Don't
|
|
test backslash-newline in C character constant. This should fix
|
|
the input.at bug reported by Nelson H. F. Beebe in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.

Calling `exit 1' is no longer needed.
|
|
Reported by Nelson H. F. Beebe.

|
|
|

|
* tests/actions.at, tests/calc.at, tests/conflicts.at,
|
|
* tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
|
|
* tests/regression.at, tests/torture.at: Use them for all the
|
|
grammars that are to be compiled.
|
|
* tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
|
|
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
|
|
* doc/bison.texinfo (GLR Parsers): Document `inline'.
|
|
|
|
2002-11-14 Akim Demaille <[email protected]>
|
|
|
|
* doc/bison.texinfo: Various formatting changes (alignments in
|
|
samples, additional @group/@end group, GCS in samples.
|
|
Use @deffn instead of simple @table to define the directives,
|
|
macros, variables etc.
|
|
|
|
2002-11-13 Paul Eggert <[email protected]>
|
|
|
|
Fix some bugs reported by Albert Chin-A-Young in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001881.html>.
|
|
|
|
* tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
|
|
-o c"; the HP C compiler chatters during compilation.
|
|
Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
|
|
* tests/headers.at (export YYLTYPE): Likewise.
|
|
|
|
* tests/input.at (Torturing the Scanner): Remove lines containing
|
|
solitary backslashes, as they tickle a bug in the HP C compiler.
|
|
|
|
* tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
|
|
comments, since they're not portable. Use GNU coding style.
|
|
|
|
2002-11-13 Akim Demaille <[email protected]>
|
|
|
|
* data/yacc.c: Leave bigger chunks of quoted text.
|
|
(YYDSYMPRINTF): New.
|
|
Use it to report symbol activities.
|
|
* data/glr.c (YYDSYMPRINTF): New.
|
|
Use it.
|
|
|
|
2002-11-12 Paul Eggert <[email protected]>
|
|
|
|
Version 1.75b.
|
|
|
|
* data/glr.c (yydoAction): Return YYRESULTTAG, not int.
|
|
(yyglrReduce): Return yyok, not 0.
|
|
This should avoid the enumerated-type warnings reported
|
|
by Nelson H.F. Beebe in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>.
|
|
|
|
* lib/bbitset.h (BITSET_INLINE): Remove.
|
|
* lib/bitset.h [! BITSET_INLINE]: Remove.
|
|
(bitset_set, bitset_reset, bitset_test): Rename local vars
|
|
to avoid shadowing warnings by GCC.
|
|
|
|
* data/glr.c (inline): Remove #define. It's the user's
|
|
responsibility to #define it away, just like 'const'.
|
|
This fixes one of the bugs reported by Nelson H.F. Beebe in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001873.html>.
|
|
|
|
* Makefile.maint (po-check): Scan .l and .y files instead of the
|
|
.c and the .h files that they generate. This fixes the bug
|
|
reported by Tim Van Holder in:
|
|
<http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
|
|
Look for N_ as well as for _. Try to avoid matching #define for
|
|
N_ and _.
|
|
* po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
|
|
src/system.h. Add src/parse-gram.y, src/scan-gram.l.
|
|
* src/scan-gram.l: Revamp regular expressions so that " and '
|
|
do not confuse xgettext.
|
|
|
|
* src/struniq.h (struniq_new): Do not declare the return type
|
|
to be 'const'; this violates the C standard.
|
|
* src/struniq.c (struniq_new): Likewise.
|
|
|
|
2002-11-12 Albert Chin-A-Young <[email protected]>
|
|
|
|
* src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

|
duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
|
|
linker.
|
|
|
|
2002-11-12 Akim Demaille <[email protected]>

|
|
|
|
Revamp to fix many (but not all) of the C- and M4-related quoting
|
|
problems. Among other things, this fixes the Bison bug reported
|
|
by Jan Hubicka when processing the Bash grammar; see:
|
|
<http://mail.gnu.org/pipermail/bison-patches/2002-November/001329.html>
|
|
|
|
Use new @ escapes consistently. Represent brackets with @{ and @}
|
|
rather than @<:@ and @:>@, since this works a bit better with dumb
|
|
editors like vi. Represent @ with @@, since @ is now consistently
|
|
an escape. Use @oline@ and @ofile@ rather than __oline__ and
|
|
__ofile__, to avoid unexpected expansions. Similarly, use @output
|
|
rather than #output.
|
|
|
|
* data/c.m4 (b4_copyright): Omit file name from comment, since
|
|
the file name could contain "*/".
|
|
(b4_synclines_flag): Don't quote the 2nd argument; it should already
|
|
be quoted. All uses changed.
|
|
|
|
* data/glr.c: Use new @ escapes consistently.
|
|
(b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
|
|
b4_output_header_suffix, b4_output_header_name, b4_header_guard):
|
|
Remove, since they couldn't handle arbitrary characters in file
|
|
names.
|
|
* data/lalr1.cc: Likewise.
|
|
* data/yacc.c: Likewise.
|
|
|
|
* src/files.c (output_infix): Remove; all uses removed.
|
|
* src/files.h: Likewise.
|
|
|
|
* data/glr.c: Remove use of "#ifdef b4_header_guard", since it
|
|
mishandled funny characters in file names, and anyway it isn't
|
|
needed any more.
|
|
* data/yacc.c: Likewise.
|
|
* data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
|
|
|
|
* data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
|
|
* data/yacc.c: Likewise.
|
|
|
|
* src/muscle_tab.c: Include quotearg.h, since we need to quote C
|
|
strings now.
|
|
(muscle_init): Quote filename as a C string.
|
|
* src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
|
|
(MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
|
|
* src/output.c (escaped_file_name_output): New function.
|
|
(prepare_symbols): Quote tokens for M4.
|
|
(prepare): Don't insert output_infix, output_prefix,
|
|
output_parser_name, output_header_name; this is now down by scan-skel.
|
|
Insert skeleton as a C string.
|
|
|
|
* src/output.c (user_actions_output, symbol_destructors_output,
|
|
symbol_printers_output): Quote filenames for C and M4.
|
|
* src/reader.c (prologue_augment, epilogue_set): Likewise.
|
|
|
|
* src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
|
|
escapes other than \\ and \'; this simplifies the code.
|
|
(<SC_STRING>): Likewise, for \\ and \".
|
|
(<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
|
|
SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
|
|
Use new escapes @{ and @} for [ and ].
|
|
|
|
* src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
|
|
them with auto vars.
|
|
Switch to new escape scheme, where @ is the escape character uniformly.
|
|
Abort if a stray escape character is found. Avoid unbounded input
|
|
buffer when parsing non-escaped text.
|
|
|
|
* tests/input.at (Torturing the Scanner): Add tests that @oline@,
|
|
__oline__, #output, $@, and @{ do not have unintended meanings.
|
|
|
|
2002-11-09 Paul Eggert <[email protected]>
|
|
|
|
Fix the test failure due to GCC warnings described in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>.
|
|
* data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
|
|
evaluate to 0 if it's impossible for NINF to be in the respective
|
|
table.
|
|
(yygetLRActions, yyrecoverParseError): Use them.
|
|
|
|
* src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
|
|
counted in the token inserted at end of file. Now takes
|
|
location_t *, not location_t, so that the location can be
|
|
adjusted. All uses changed.
|
|
|
|
* tests/regression.at (Invalid inputs): Adjust wording in
|
|
diagnostic to match the new behavior.
|
|
|
|
* tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
|
|
AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
|
|
AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
|
|
abort ();'. This reduces the runtime of the "Many lookaheads"
|
|
test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
|
|
GCC 3.2.
|
|
|
|
2002-11-07 Paul Eggert <[email protected]>
|
|
|
|
* src/parse-gram.y (CHARACTER): Remove unused token.
|
|
All uses removed.
|
|
|
|
* src/scan-gram.l: Remove stack option. We no longer use the
|
|
stack, since the stack was never deeper than 1; instead, use the
|
|
new auto var c_context to record the stacked value.
|
|
|
|
Remove nounput option. At an unexpected end of file, we now unput
|
|
the minimal input necessary to end cleanly; this simplifies the
|
|
code.
|
|
|
|
Avoid unbounded token sizes where this is easy.
|
|
|
|
(unexpected_end_of_file): New function.
|
|
Use it to systematize the error message on unexpected EOF.
|
|
(last-string): Now auto, not static.
|
|
(YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
|
|
(scanner_last_string_free): Remove; not used.
|
|
(percent_percent_count): Move decl to just before use.
|
|
(SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
|
|
not the (never otherwised-used) CHARACTER.
|
|
|
|

|
|
accordingly.
|
|

|
|
Also, remove one static variable in the scanner.

|
|
|
|
2002-11-04 Akim Demaille <[email protected]>

(YY_STEP): Omit trailing semicolon, so that it's more like C.
|
|
|
|
(<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
|
|
as well as \000. Check for UCHAR_MAX, not 255.
|
|
Allow \x with an arbitrary positive number of digits, as in C.
|
|
Check for overflow here.
|
|
Allow \? and UCNs, for compatibility with C.
|
|
|
|
(handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
|
|
with quote slot used by complain_at.
|
|
|
|
* tests/input.at: Add tests for backslash-newline, m4 quotes
|
|
in symbols, long literals, and funny escapes in strings.
|
|
|
|
* configure.ac (jm_PREREQ_MBSWIDTH): Add.
|
|
* lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
|
|
* lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
|
|
* m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
|
|
* m4/mbswidth.m4: New file, from GNU coreutils.
|
|
|
|
* doc/bison.texinfo (Grammar Outline): Document // comments.
|
|
(Symbols): Document that trigraphs have no special meaning in Bison,
|
|
nor is backslash-newline allowed.
|
|
(Actions): Document that trigraphs have no special meaning.
|
|
|
|
* src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
|
|
no longer used.
|
|
|
|
2002-11-02 Paul Eggert <[email protected]>
|
|
|
|
* src/reader.c: Don't include quote.h; not needed.
|
|
(get_merge_function): Reword warning to be consistent with
|
|
type clash diagnostic in grammar_current_rule_check.
|
|
|
|
* lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
|
|
bug in trigraph handling.
|
|
|
|
* src/output.c (prepare_symbols): When printing token names,
|
|
escape "[" as "@<:@" and likewise for "]".
|
|
|
|
* src/system.h (errno): Remove declaration, as we are now
|
|
assuming C89 or better, and C89 guarantees errno.
|
|
|
|
2002-10-30 Paul Eggert <[email protected]>
|
|
|
|
* lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
|
|
Check for close failures.
|
|
* src/files.h (xfclose): Return void, not int, since it always
|
|
returned zero.
|
|
* src/files.c (xfclose): Likewise. Report I/O error if ferror
|
|
indicates one.
|
|
* src/output.c (output_skeleton): Use xfclose rather than fclose
|
|
and ferror. xfclose now checks ferror.
|
|
|
|
* data/glr.c (YYLEFTMOST_STATE): Remove.
|
|
(yyreportTree): Use a stack-based leftmost state. This avoids
|
|
our continuing battles with bogus warnings about initializers.
|
|
|
|
2002-10-30 Akim Demaille <[email protected]>
|
|
|
|
* src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
|
|
#if.
|
|
|
|
2002-10-29 Paul Hilfinger <[email protected]>
|
|
|
|
* tests/glr-regr1.at: New test for reported regressions.
|
|
* tests/testsuite.at: Add glr-regr1.at test.
|
|
* tests/Makefile.am: Add glr-regr1.at test.
|
|
|
|
2002-10-24 Paul Eggert <[email protected]>
|
|
|
|
Version 1.75a.
|
|
|
|
* tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
|
|
* tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
|
|
we use malloc. Don't assume 'A' through 'Z' are contiguous.
|
|
Don't assume strdup exists; POSIX says its an XSI extension.
|
|
Check for buffer overflow on input.
|
|
|
|
2002-10-24 Akim Demaille <[email protected]>
|
|
|
|
* src/output.c (output_skeleton): Don't disable M4sugar comments
|
|
too soon: it results in comments being expanded.
|
|
* data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
|
|
first output.
|
|
|
|
2002-10-24 Akim Demaille <[email protected]>
|
|
|
|
* data/yacc.c (m4_int_type): New.
|
|
* data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
|
|
char' as only yacc.c wants K&R portability.
|
|
* data/glr.c (yysigned_char): Remove.
|
|
* data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
|
|
Reported by Quoc Peyrot.
|
|
|
|
2002-10-23 Paul Eggert <[email protected]>
|
|
|
|
* src/main.c (main): With --trace=time, report times even if a
|
|
non-fatal error occurs. Formerly, the times were reported in some
|
|
such cases but not in others.
|
|
* src/reader.c (reader): Just return if a complaint has been issued,
|
|
instead of exiting, so that 'main' can report times.
|
|
|
|
2002-10-22 Akim Demaille <[email protected]>
|
|
|
|
* src/system.h: Include sys/types.
|
|
Reported by Bert Deknuydt.
|
|
|
|
2002-10-23 Paul Eggert <[email protected]>
|
|
|
|
* configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
|
|
Suggested by Art Haas.
|
|
|
|
2002-10-22 Paul Eggert <[email protected]>
|
|
|
|
* src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
|
|
decl; not needed any more.
|
|
* src/main.c (main): Use return to exit, undoing yesterday's change.
|
|
The last OS that we could find where this wouldn't work is
|
|
SunOS 3.5, and that's too old to worry about now.
|
|
|
|
* data/glr.c (struct yyltype): Define members even when not
|
|
doing locations. This is more consistent with yacc.c, and it
|
|
works around the following bug reports:
|
|
http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
|
|
http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
|
|
and I hope it also fixes this bug report:
|
|
http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
|
|
|
|
* doc/bison.texinfo: Minor spelling and typographical fixes. Use
|
|
@acronym consistently. Standardize on "Yacc" instead of "YACC",
|
|
"Algol" instead of "ALGOL". Give a bit more history about BNF.
|
|
|
|
2002-10-22 Akim Demaille <[email protected]>
|
|
|
|
* data/README: New.
|
|
|
|
2002-10-21 Paul Eggert <[email protected]>
|
|
|
|
Be consistent about 'bool'; the old code used an enum in one
|
|
module and an int in another, and this violates the C standard.
|
|
* m4/stdbool.m4: New file, from coreutils 4.5.3.
|
|
* configure.ac (AC_HEADER_STDBOOL): Add.
|
|
* m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
|
|
* src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
|
|
* src/symtab.c (hash_compare_symbol_t): Likewise.
|
|
* src/system.h (bool, false, true): Use a definition consistent
|
|
with ../lib/hash.c. All uses changed.
|
|
|
|
* src/complain.c (warning_issued): Renamed from warn_message_count,
|
|
so that we needn't worry about integer overflow (!).
|
|
Now of type bool. All uses changed.
|
|
(complaint_issued): Renamed from complain_message_count; likewise.
|
|
|
|
* src/main.c (main): Use exit to exit with failure.
|
|
|
|
* src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
|
|
rather than 1 and 0.
|
|
* src/main.c (main): Likewise.
|
|
* src/getargs.c (getargs): Likewise.
|
|
* src/reader.c (reader): Likewise.
|
|
|
|
* src/getarg.c (getargs): Remove duplicate code for
|
|
"Try `bison --help'".
|
|
|
|
* src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
|
|
What was that "2" for?
|
|
|
|
* src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
|
|
* src/getargs.c (usage): Likewise.
|
|
|
|
* src/getargs.c (getargs): When there are too few operands, report
|
|
the last one. When there are too many, report the first extra
|
|
one. This is how diffutils does it.
|
|
|
|
2002-10-20 Paul Eggert <[email protected]>
|
|
|
|
Remove K&R vestiges.
|
|
* configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
|
|
* src/complain.c (VA_START): Remove. Assume prototypes.
|
|
(vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
|
|
(private_strerror, warn_at, warn, complain_at, complain, fatal_at,
|
|
fatal): Assume prototypes.
|
|
* src/complain.h: Assume prototypes.
|
|
* src/system.h (PARAMS): Remove.
|
|
Include <limits.h> unconditionally, since it's guaranteeed even
|
|
for a freestanding C89 compiler.
|
|
(SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
|
|
* src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
|
|
|
|
2002-10-20 Akim Demaille <[email protected]>

|
|
(yy_reduce_print): New.

|
|
|
|
2002-10-20 Akim Demaille <[email protected]>

|
|
arguments and output `void'.
|
|
(b4_c_function): Rename as...
|
|
(b4_c_function_def): this.
|
|
(b4_c_function_decl, b4_c_ansi_function_def)
|
|
(b4_c_ansi_function_decl): New.
|
|
Change the interpretation of the arguments: before `int, foo', now
|
|
`int foo, foo'.
|
|
* data/yacc.c (yyparse): Prototype and define thanks to these.
|
|
Adjust b4_c_function_def uses.
|
|
* data/glr.c (yyparse): Likewise, but ANSI only.
|
|
|
|
2002-10-20 Akim Demaille <[email protected]>

`pair'.

|
|
These.

2002-10-19 Paul Eggert <[email protected]>
|
|
|
|
Do not create a temporary file, as that involves security and
|
|
cleanup headaches. Instead, use a pair of pipes.
|
|
Derived from a suggestion by Florian Krohm.
|
|
* lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
|
|
* lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
|
|
* configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
|

|
Add subpipe.h, subpipe.c.

|
* po/POTFILES.in: Add lib/subpipe.c.
|
|
* src/output.c: Include "subpipe.h".
|
|
(m4_invoke): Remove decl.
|
|
(scan_skel): New decl.
|
|
(output_skeleton): Use pipe rather than temporary file for m4 input.
|
|
Check that m4sugar.m4 is readable, to avoid deadlock.
|
|
Check for pipe I/O error.
|
|
* src/scan-skel.l (readpipe): Remove decl.
|
|
(scan_skel): New function, to be used in place of m4_invoke.
|
|
Read from stream rather than file.
|
|
|
|
* lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
|
|
float, as this generates a warning on Solaris 8 + GCC 3.2 with
|
|
--enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
|
|
this generates a more-accurate value anyway.
|
|
|
|
* lib/timevar.c (timervar_accumulate): Rename locals to
|
|
avoid confusion with similarly-named more-global.
|
|
* src/muscle_tab.c (muscle_pair_list_grow): Likewise.
|
|
|
|
* src/output.c (prepare): Use xstrdup to convert char const *
|

to char *, to avoid GCC warning.
|
|
|
|
2002-10-19 Akim Demaille <[email protected]>
|
|
|

* tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
|
|
LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
|
|
Use them to have `calc.y' ready for %pure-parser.
|
|
* data/yacc.c (YYLEX): Pass a yylex return type to
|
|
b4_c_function_call.
|
|
|
|
2002-10-19 Akim Demaille <[email protected]>
|

Initialize the obstack earlier.

(AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
|
|
|

2002-10-19 Akim Demaille <[email protected]>
|
|
|
|
* src/getargs.c (usage): Take status as argument and exit
|
|
accordingly.
|
|
Report the traditional `Try ... --help' message when status != 0.
|
|
(usage, version): Don't take a FILE * as arg, it is pointless.
|
|
(getargs): When there is an incorrect number of arguments, make it
|
|
an error, and report it GNUlically thanks to `usage ()'.
|
|
|
|
2002-10-18 Paul Eggert <[email protected]>
|
|
|
|
* data/glr.c (yyreportParseError): Don't assume that sprintf
|

yields the length of the printed string, as this is not true
|

on SunOS 4.1.4. Reported by Peter Klein.
|
|
|
|
* tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.

|
|
* src/reader.c (grammar_current_rule_prec_set)

(grammar_current_rule_dprec_set, grammar_current_rule_merge_set):

Standardize error messages.

And s/@prec/%prec/!
|
|
(reader): Use trace_flag to enable scanner/parser debugging,
|
|
instead of an adhoc scheme.
|
|
* src/scan-gram.l: Remove trailing debugging code.
|
|
|
|
2002-10-16 Paul Eggert <[email protected]>
|
|
|

|
|
* NEWS: Officially drop support for building Bison with K&R C,

|
|
|
|
Stop using the "enum_" trick for K&R-style function definitions;
|
|
it confused me, and I was the author! Instead, assume that people
|
|
who want to use K&R C compilers (when using these modules in GCC,
|
|
perhaps?) will run ansi2knr.
|
|
|
|
* lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.

Let nondeterministic skeletons be usable with deterministic
|
|
tables.
|
|
|
|
With the patch, GAWK compiled by GCC without -O2 passes its test
|
|
suite using a GLR parser driven by LALR tables. It fails with -O2
|
|
because `struct stat' gives two different answers on my machine:
|
|
88 (definition of an auto var) and later 96 (memset on this var).
|
|
Hence the stack is badly corrumpted. The headers inclusion is to
|
|
blame: if I move the awk.h inclusion before GLR's system header
|
|
inclusion, the two struct stat have the same size.
|
|
|
|
* src/tables.c (pack_table): Always create conflict_table.

GLR parsers sometimes raise parse errors instead of performing the
|
|
default reduction.
|
|
Reported by Charles-Henry de Boysson.
|
|
|
|
* tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't

YYTABLE_NINF to 0.
|
|
(yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
|
|
(which was a bug: it should have been YYTABEL_NINF, and yet it was
|
|
not satisfying as we could compare an YYACTION computed from
|
|
YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
|

only value for error actions.

Fix problem reported by Henrik Grubbstroem in
|
|
<http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
|
|
"nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
|
|
because the Bison parser reads the second action before reducing
|
|
the first one.
|
|
* src/scan-gram.l (rule_length): New static var.
|
|
Use it to keep track of the rule length in the scanner, since
|
|
we can't expect the parser to be in lock-step sync with the scanner.
|
|
(handle_action_dollar, handle_action_at): Use this var.

Use same include order as source.

* lib/abitset.c: Include <stddef.h>, for offsetof.
|
|
* lib/lbitset.c: Likewise.
|
|
|
|
* lib/abitset.c (abitset_bytes): Return a size that is aligned

|
properly for vectors of objects. Do not assume that adding a

|
header size to a multiple of a word size yields a value that is
|
|
properly aligned for the whole union.
|
|
* lib/bitsetv.c (bitsetv_alloc): Likewise.
|
|
|
|
* lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,

|
* lib/lbitset.c (enum_lbitset_find_mode): Likewise.
|
|
|
|
Do not use "struct bitset_struct" to mean different things in

different modules. Not only is this confusing, it violates
|
|
the C Standard, which requires that structure types in different
|
|
modules must be compatible if one is to be passed to the other.
|
|
* lib/bbitset.h (bitset): Now points to a union, not to a struct.
|
|
All instances of "struct bitset_struct *" replaced with "bitset".

struct lbitset_struct, struct bitset_stats_struct): New types.

All uses of struct bitset_struct changed to union bitset_union,

|
|
Likewise.
|
|
|
|
Do not call a function of type T using a call that assumes the
|
|
function is of a different type U. Standard C requires that a
|
|
function must be called with a type that is compatible with its

Use offsetof, for simplicity.

2002-10-06 Paul Eggert <[email protected]>
|
|
|
|
* lib/bitset.h (bitset_reset): Do not assume that bitset_word is

the same width as int. This reapplies a hunk of the 2002-08-12 patch
|
|
<http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,

the portable Standard C character set.
|
|
|

to void, to avoid a GCC warning when --disable-nls is in effect.
|
|

|
|
to minimize the number of warnings from xgettext.
|
|
(handle_action_dollar, handle_action_at): Don't use isdigit,

as it mishandles negative chars and it may not work as expected
|
|
outside the C locale.

|

this is a GCC extension and is not portable to other compilers.

|
|
Do not include <ctype.h>; no longer needed.

|
|
it's not portable.

Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.

|
|
exit status as failure, not just exit status 1. Sun C exits

|
|
Use it for the two large tests.

`lookaheads_rule' member.

by conflicts.

different: save its reduction (accept) instead of having a state

|
|
parsers now contain `reduce 0' as default reduction.

|
|

|
|
* tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the

full stderr, and strip it according to the bison options, instead

|
|
(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.
|

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.

2002-04-07 Akim Demaille <[email protected]>
|

|
|
|
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.
|

|
|
|
|
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.

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/LR0.c (allocate_itemsets, new_itemsets): Adjust.

reductions, then output the report anyway if requested, then die.

|
|
* 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.

Prefer high to wide: output the state number on a line of its own.

|
|
(copy_action, copy_guard): these two which are renamed as...

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

All the hacks using a final pseudo state are now useless.

* src/lalr.c (nLA): New.

instead of lookaheadsp from the pseudo state (nstate + 1).

|
|

lookaheadsp.

|
|
(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).

duplicates ntokens.

Use YYNTOKENS only, which is documented, but not YYNTBASE, which

Reported by Nelson Beebee.
|
|
|
|

|
|
|

|
|
otherwise, since we range over their symbols, we might look at a

nonterminal which no longer ``exists'', i.e., it is not counted in

* 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.
|
|
|
|

|
|
|
* 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]>
|
|
|
|

|
|
|
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.

|
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
|

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]>

|
|
|
|
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.
|

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]>

2001-12-05 Akim Demaille <[email protected]>
|
|
|

|
|
|
|
2001-12-05 Akim Demaille <[email protected]>
|

Pessimize the code to simplify it: from now on, all the states

deallocation.

`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.

|
|
* src/gram.c, src/gram.h (ritem_print): New.
|
|

(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.
|

|
|
on user names when possible.
|
|
|
|
(YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
|
|
Simplify test for whather <alloca.h> exists.

|
|
|
|

|
they all begin with 'yy'.

(yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
|
|
instead of relying on string.h functions. Use YYSTACK_ALLOC
|

|
|
2001-11-30 Akim Demaille <[email protected]>

|
|
(__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.

|
*in* the input file now.
|
|
(output_files): Do it here.
|
|

|
|
prevents type checking.
|

|
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/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'.

* 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.

|
|
Adjust all dependencies.
|

`reader_output_yylsp'.

former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

|
|
|
|
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.

|
|
|
|
`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.
