Paul Eggert 087b9fdf03 (Torturing the Scanner): Add tests for ";|" in a grammar. 2003-05-14 19:26:52 +00:00
Paul Eggert 8d0a98bb50 (rules_or_grammar_declaration): Require a 
semicolon after a grammar declaration, in the interest of possible
future changes to the Bison input language.
Do not allow a stray semicolon at the start of the grammar.
(rhses.1): Allow one or more semicolons after any rule, including
just before "|" as required by POSIX.

Alexandre Duret-Lutz caf37a3666 %parse-param support for lalr1.cc. 
* data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
b4_cc_constructor_calls, b4_cc_constructor_call,
b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
definitions.
(yy::b4_parser_class_name::b4_parser_class_name): Take extra
parse-param arguments.
(yy::b4_parser_class_name): Declare instance variables to
hold parse-param arguments.
* tests/calc.at: s/value/semantic_value/ because value clashes
with a member of yy::b4_parser_class_name.  Adjust C++ code
to handle %parse-param.  Enable %parse-param test in C++.
 2003-05-14 18:41:48 +00:00
Paul Eggert 3ab370773d * doc/bison.texinfo (How Can I Reset @code{yyparse}): 
Minor English and technical fixups.
 2003-05-12 19:35:13 +00:00
Paul Eggert 0e14ad772f (How Can I Reset @code{yyparse}): Reword the 
English a bit.  Fix fclose typo.  Change "const char" to "char
const", and use ANSI C rather than K&R for "main".  Suggest
YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
and suggest yy_switch_to_buffer.

Paul Eggert 163ab32161 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes C89. 2003-05-05 20:39:42 +00:00
Paul Eggert cfbb7304d8 (__INT_TO_PTR): Define to a value that presumes C89. 
This avoids a diagnostic on compilers that define __STDC__
to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
 2003-05-05 20:39:04 +00:00
Paul Eggert e743727fcd * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE): 
Do not overrun array bounds.
 2003-05-04 06:30:14 +00:00
Paul Eggert 2175bfbd09 (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE): 
Do not overrun array bounds.
This should fix a bug reported today by Olatunji Oluwabukunmi in
<http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.

Paul Eggert a1c84f4523 Omit spaces around "---". 2003-04-29 18:53:33 +00:00
Akim Demaille 916708d59e * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to... 
* src/getargs.c, src/getargs.h: here, as bool, not int.
(nondeterministic_parser): New.
* src/parse-gram.y, src/scan-gram.l: Support
%nondeterministic-parser.
* src/output.c (prepare): Use nondeterministic_parser instead
of glr_parser where appropriate.
* src/tables.c (conflict_row, action_row, save_row)
(token_actions, token_actions, pack_vector): Ditto.
 2003-04-29 12:57:36 +00:00
Akim Demaille a06ea4aa98 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New. 2003-04-29 09:57:34 +00:00
Akim Demaille ca752c3497 Update. 2003-04-29 09:16:50 +00:00
Akim Demaille 211074caca * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet) 
with %pure-parser and %locations to exercise the patch from Yakov
Markovitch below.
 2003-04-29 08:41:13 +00:00
Akim Demaille 2f924dd373 Regen. 2003-04-29 08:31:48 +00:00
Paul Eggert 6175ffe321 * data/yacc.c: (b4_lex_param): Corrected for the case where 
%lex-param is provided and %pure-parser isn't.
 2003-04-29 06:04:56 +00:00
Paul Eggert 68cdf74747 (b4_lex_param): Corrected for the case where %lex-param is provided 
and %pure-parser isn't.

Paul Eggert b1e9585744 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.

Paul Eggert b929851a33 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
(YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA if it is not defined.
(YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.

Paul Eggert 3470c57bea * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_): 
Declare to be of type suitable for the ninf value itself.
 2003-04-27 05:57:13 +00:00
Paul Eggert 0c3c1f98ec (yy::Parser::pact_ninf_, yy::Parser::table_ninf_): 
Declare to be of type suitable for the ninf value itself, not of
type suitable for the corresponding table, since the latter might
be unsigned but the ninf value might be negative.  This fixes a
bug reported by Alexandre Duret-Lutz in
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
 2003-04-27 05:56:34 +00:00
Paul Eggert acda9df6f9 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR invokes it. 2003-04-27 05:28:21 +00:00
Paul Eggert b59d8a44df (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR 
invokes it.  We shouldn't invoke it twice because it will attempt
to put error.o in the archive twice.  This fixes a glitch reported
by Martin Mokrejs in
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
 2003-04-27 05:27:15 +00:00
Paul Eggert b5250f2635 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch to gnulib. 2003-04-22 03:33:29 +00:00
Paul Eggert 3192f9ece7 Update from Bruno Haible's 2003-04-14 patch to gnulib. 2003-04-22 03:33:01 +00:00
Paul Eggert 089ac0f11c * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]: 
Fix obvious typo that results in uncompilable GLR parsers
when both %pure-parser and %locations are used.  (trivial change)
 2003-04-21 19:37:40 +00:00
Paul Eggert 1d2d7eddf7 (yyexpandGLRStack) [!YYSTACKEXPANDABLE]: 
Fix obvious typo that results in uncompilable GLR parsers
when both %pure-parser and %locations are used.  (trivial change
from Yakov Markovitch <Markovitch@iso.ru>)
 2003-04-21 19:37:09 +00:00
Paul Eggert 1b8f2fff2a Don't invoke unput from scan-gram.l; it ran into a POSIX-compatibility 
bug in flex 2.5.31.
 2003-04-18 07:27:15 +00:00
Paul Eggert 47e7600a21 (Invalid inputs): Remove cascaded diagnostic that is no longer emitted. 2003-04-18 07:26:46 +00:00
Paul Eggert aa4180418f Add %option nounput, since we no longer use unput. 
(unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
Do not insert the expected token via unput, as this runs afoul
of a POSIX-compatibility bug in flex 2.5.31.
All uses changed to BEGIN the parent state,
since we no longer insert the expected token via unput.

Paul Eggert 5ededac618 Fix regression reported by Werner Lemberg in 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
 2003-04-18 05:11:25 +00:00
Paul Eggert 2740f1691f (GNU pic Grammar): New test case, taken from 
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
 2003-04-18 05:10:58 +00:00
Paul Eggert 0de45ae542 (set_conflicts): Resolve all conflicts, not just 
the first one.  This change is from Paul Hilfinger, and it fixes
regression reported by Werner Lemberg in
<http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.

(resolve_sr_conflict): Don't invoke state_errs_set
unless one or more tokens have been explicitly made errors.
Otherwise, the above change causes Bison to abort.
 2003-04-18 05:07:08 +00:00
Akim Demaille b8be913233 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file. 2003-03-31 09:46:21 +00:00
Akim Demaille d423d46080 * src/output.c (prepare_symbols): Avoid trailing spaces in the 
output.
 2003-03-31 09:17:40 +00:00
Akim Demaille c7e441b49c * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/. 
From Paul Hilfinger.
 2003-03-31 07:10:44 +00:00
Akim Demaille 231897ad21 * m4/error.m4: Do not put under dynamic conditions some code which 
expansion is under static control.
 2003-03-29 13:50:44 +00:00
Akim Demaille 22a74fece3 Restore a missing ChangeLog entry. 2003-03-29 13:30:15 +00:00

Paul Eggert 537636c7e5 Fix "Bison blows chunks on empty file" bug. 
Work around SunOS 4.1.4 porting problem with <sys/resource.h>.
Don't check for sys/wait.h twice, with two different algorithms.
 2003-03-13 07:13:05 +00:00
Paul Eggert 379f0ac840 (YY_USER_INIT): Initialize code_start, too. 
(<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
cursor, instead of leaving it undefined.  This fixes a bug
reported by Tim Van Holder in
<http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
