This + doesn't affect behavior. + (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for + Solaris, AIX, MSC. + (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed. + This works a bit better with glibc, if user code has already included + stdlib.h. + * doc/bison.texinfo (Bison Parser): Document that users can't + arbitrarily use malloc and free for other purposes. Document + that and might be included. + (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the + user must declare alloca. + + * HACKING (release): Forwarn the Translation Project about + stable releses. + +2005-09-20 Akim Demaille + + * data/glr.c: Use b4_token_enums, not b4_token_enums_defines. + +2005-09-19 Paul Eggert + + * data/yacc.c (YYSIZE_MAXIMUM): New macro. + (YYSTACK_ALLOC_MAXIMUM): Use it. + (yysyntax_error): New function. + (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if + multiple syntax errors are reported, and alloca is being used. + Instead, reallocate buffers twice as big each time, so that + we waste at most half the allocated memory. Start with a small + (128-byte) buffer that will suffice in most cases anyway. + Use yysyntax_error to do most of the work. + + * doc/bison.texinfo (Error Reporting, Table of Symbols): + yynerrs is the number of errors reported, not the number of + errors encountered. + + * tests/glr-regression.at (Duplicated user destructor for lookahead): + Mark it as expected to fail. + Cast result of malloc; problem reported by twlevo@xs4all.nl. + * tests/actions.at, tests/calc.at, tests/glr-regression.at: + Don't start user-code symbols with "yy", to avoid name space problems. + +2005-09-19 Akim Demaille + + Remove the traits, failed experiment. + It never proved useful, and anyway because of the current + definition, it was not possible to have several specialization of + this traits, making it useless. + * data/lalr1.cc (yy:traits): Remove. + Inline its definitions in the parser class. + +2005-09-19 Akim Demaille + + * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at + least Mac OSX with a /usr/local install of gettext. + +2005-09-19 Akim Demaille + + * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar + and yytoken for similarity with the other skeletons. + +2005-09-19 Akim Demaille + + * NEWS, configure.ac: Bump to 2.1a. + +2005-09-16 Paul Eggert + + * NEWS: Version 2.1. + + * NEWS: Remove notice of yytname change, since it was never in an + official release. + * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing + diagnostic. + * src/output.c (prepare): Likewise. + * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro. + (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE + is not defined. This is an awful hack, but it's enough for now. + All callers changed. + * tests/glr-regression-at (make_value): Args are const pointers now, + to avoid GCC warning. + (Duplicated user destructor for lookahead): New test. Currently + skipped. It fails on my host but I'm not sure it'll always fail. + +2005-09-16 Akim Demaille + + * src/symtab.h (struct symbol): Declare the printer and destructor + as const, to avoid accidental calls to free. + (symbol_destructor_set, symbol_printer_set): Adjust. + * src/symtab.c: Adjust. + +2005-09-16 Akim Demaille + + * data/c.m4 (b4_token_enums): New. + (b4_token_defines): Rename as... + (b4_token_enums_defines): this. + (b4_token_defines): New, output only the #defines. + * data/yacc.c, data/glr.c: Adjust. + * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines. + * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define + as default values. + +2005-09-16 Akim Demaille + + * data/lalr1.cc (yylex_): Remove, inline its code. + (yyreport_syntax_error_): Remove, replaced by... + (yysyntax_error_): this which returns a string and leaves to the + caller the call to the users' error function. + (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc): + Move from members of the parser object... + (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc): + to local variables of the parse function. + +2005-09-16 Akim Demaille + + * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF + since it's in Bison's name space. + 2005-09-15 Paul Eggert + * data/glr.c (yyresolveValue): Add default case to pacify + gcc -Wswitch-default.
