  • 3192f9ece7 Update from Bruno Haible's 2003-04-14 patch to gnulib. Paul Eggert 2003-04-22 03:33:01 +00:00
  • 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) Paul Eggert 2003-04-21 19:37:40 +00:00
  • 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>) Paul Eggert 2003-04-21 19:37:09 +00:00
  • 1b8f2fff2a Don't invoke unput from scan-gram.l; it ran into a POSIX-compatibility bug in flex 2.5.31. Paul Eggert 2003-04-18 07:27:15 +00:00
  • 47e7600a21 (Invalid inputs): Remove cascaded diagnostic that is no longer emitted. Paul Eggert 2003-04-18 07:26:46 +00:00
  • 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 2003-04-18 07:26:19 +00:00

  • 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. Paul Eggert 2003-03-13 07:13:05 +00:00
  • 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>. Paul Eggert 2003-03-13 07:07:17 +00:00

  • a93df6bad3 (BISON_PREREQ_TIMEVAR): When checking whether <sys/resource.h> can be included, include sys/time.h and sys/times.h first, if available. This works around the SunOS 4.1.4 porting bug reported by Bruce Becker in <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>. Paul Eggert 2003-03-13 00:25:33 +00:00
  • 8012adae7b (BISON_PREREQ_SUBPIPE): Don't AC_CHECK_HEADERS([sys/wait.h]), as this interferes with AC_HEADER_SYS_WAIT. Paul Eggert 2003-03-13 00:01:07 +00:00
  • f61aad9399 Merge changes from gnulib. This was prompted because the CVS snapshot of Bison didn't build on Solaris 7 due to strnlen problems. Paul Eggert 2003-03-12 23:08:11 +00:00
  • 4f8a9f6dba Include <limits.h> unconditionally. We have been assuming at least C89 in the bitset code for some time now. Paul Eggert 2003-03-12 23:01:22 +00:00

  • 052826fdd1 * doc/bison.texinfo (Table of Symbols): Reactivate the documentation for %lex-param, and %parse-param. Akim Demaille 2003-03-02 15:11:43 +00:00
  • c47495657b * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to generate verbose error messages. Use the number of tokens as an upper bound in yytname, as it cannot be a non terminal. Akim Demaille 2003-03-02 13:39:44 +00:00
  • d5286af19b * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error message. Akim Demaille 2003-03-02 13:36:55 +00:00
  • 95b52400d5 Typo. Akim Demaille 2003-03-02 11:27:59 +00:00
  • 22e304a6da Write a test the yycheck overrun reported by Andrew Suffield. * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New. Use them to exercise yycheck overrun. Based on Andrew Suffield's grammar. Akim Demaille 2003-03-02 11:22:19 +00:00
  • 67a25fed4c Create tests/local.at for Bison generic testing macros. * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to... * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS): This new file. * tests/calc.at (AT_CHECK_CALC): Adjust. * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR) (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to... * tests/local.at: here.

  • 9c2b381f79 Minor improvements to today's scan-gram.l bugfix. Paul Eggert 2003-03-02 06:56:06 +00:00
  • a2bc9dbc7b (code_start): Initialize it to scanner_cursor, not loc->end, since loc->end might contain garbage and this leads to undefined behavior on some platforms. (id_loc, token_start): Use (IF_LINTed) initial values that do not depend on *loc, so that the reader doesn't give the the false impression that *loc is initialized. (<INITIAL>"%%"): Do not bother setting code_start, since its value does not survive the return. Paul Eggert 2003-03-02 06:55:15 +00:00
  • 0433ba88f9 * src/scan-gram.l (code_start): Always initialize it when entering into yylex, as SC_EPILOGUE is activated *before* the corresponding yylex invocation. An alternative would be making it static, but then it starts with the second %%'s beginning, instead of its end. Akim Demaille 2003-03-01 10:55:31 +00:00
  • 6d5aa694aa Regen. Akim Demaille 2003-03-01 08:31:06 +00:00

(_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is not defined. Don't use the location in yy::Parser::error_ and yy::Parser::print_ when not %locations. Activate more lalr1.cc tests. Akim Demaille 2003-02-20 08:14:27 +00:00
  • 0d1c3a04b7 * data/lalr1.cc: When displaying a line number, be sure to make it an int. Akim Demaille 2003-02-19 14:55:14 +00:00

  • da99a5dc03 * tests/atlocal.in (LDFLAGS, LIBS): New vars. * tests/testsuite.at (AT_COMPILE): Use them. This fixes the testsuite problem reported by Robert Lentz in <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>. Paul Eggert 2003-02-18 05:10:12 +00:00

  • 6cee62971e * data/lalr1.cc: Do not use @output_header_name@ unless b4_defines_flag is set. Paul Eggert 2003-01-29 06:31:41 +00:00

Paul Eggert 2003-01-29 06:31:02 +00:00
  • b2a836b51e * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that we don't need to worry about yyerrlab1 being reported as an "unused label" by non-GCC C compilers. Paul Eggert 2003-01-22 06:39:16 +00:00
  • 8a3eb3c8ba (YYERROR): Move code from yyerrlab1 to here, so that we don't need to worry about yyerrlab1 being reported as an "unused label" by non-GCC C compilers. The downside is that if locations are used then a couple of statements are duplicated each time YYERROR is invoked, but the upside is that the warnings should vanish. (yyerrlab1): Move code to YERROR. (yyerrlab2): Remove. Change uses back to yyerrlab1. This reverts some of the 2002-12-27 change. Paul Eggert 2003-01-22 06:38:32 +00:00

  • 34e1d16097 (symbol_printers_output): Fix typo that led to core dump. Problem reported by Antonio Rus in <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>. Paul Eggert 2003-01-17 08:43:08 +00:00
  • 3ae831b413 Quoc Peyrot <chojin@lrde.epita.fr>, Robert Anisko <anisko_r@lrde.epita.fr> * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop when the stacks contain one element, as the loop would otherwise free the last state, and then use the top state (the one we just popped). This means that the initial elements will not be freed explicitly, as is the case in yacc.c; it is not a problem, as these elements have fake values. Akim Demaille 2003-01-13 15:42:31 +00:00

  • 69363a9e4d * NEWS: %expect-violations are now just warnings, reverting to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2 bootstrapping problem reported by Matthias Klose; see <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>. * src/conflicts.c (conflicts_print): Likewise. * tests/conflicts.at (%expect not enough, %expect too much, %expect with reduce conflicts): Likewise. * doc/bison.texinfo (Expect Decl): Document this. Also mention that the warning is enabled if the number of conflicts changes (not necessarily increases). Paul Eggert 2003-01-13 06:41:29 +00:00
