Denny + + Minor code cleanup. + * src/parse-gram.y: Clean up sorting of declarations. + Use types to simplify %printer declarations where possible. + Provide %printer for BRACKETED_ID and symbol.prec. + * src/symtab.c: Whitespace change. + +2009-10-04 Joel E. Denny + + tests: skip tests of file names that platform does not support. + Reported by Michael Raskin at + . + * THANKS (Michael Raskin): Add. + * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Fix. Cygwin used + to fail at least for file names containing ":" or "\". + +2009-09-23 Joel E. Denny + + yysyntax_error: avoid duplicate lookahead collection. + Except when memory reallocation is required, this change + eliminates the need to invoke yysyntax_error twice and thus to + repeat the collection of lookaheads. It also prepares for + future extensions that will make those repetitions more + expensive and that will require additional memory management in + yysyntax_error. Finally, it fixes an obscure bug already + exercised in the test suite. + * data/yacc.c (yysyntax_error): Add arguments for message + buffer variables stored in the parser. Instead of size, return + status similar to yyparse status but indicating success of + message creation. Other than the actual reallocation of the + message buffer, import and clean up memory management code + from... + (yyparse, yypush_parse): ... here. + * tests/regression.at (%error-verbose overflow): No longer an + expected failure. + +2009-09-23 Joel E. Denny + + yysyntax_error: test memory management more. + * tests/atlocal.in (NO_WERROR_CFLAGS): New cpp macro. + * tests/regression.at (%error-verbose and YYSTACK_USE_ALLOCA): + New test group. + (%error-verbose overflow): New test group that reveals an + obscure bug. Expected fail for now. + +2008-12-11 Akim Demaille + + Pass the token type to yysyntax_error. + * data/yacc.c (yysyntax_error): Take the transated token instead + of the raw number. + Adjust callers. + +2008-12-11 Akim Demaille + + Simplify the i18n of the error messages. + * data/yacc.c (yysyntax_error): Rewrite, using a switch instead + of building dynamically the format string. + +2009-10-03 Joel E. Denny + + Remove dead code. + * src/symtab.c (symbol_pack): Here because every symbol's number + is always defined by this time. + +2009-10-03 Alex Rozenman + + Add additional space after periods in NEWS. + * NEWS (2.5): here. + +2009-09-29 Joel E. Denny + + Use the correct conversion specifier for size_t. + Reported by Jim Meyering. + * src/Sbitset.h (SBITSET__INDEX__CONVERSION_SPEC): New, "zu" + because Sbitset__Index is size_t. + * src/Sbitset.c (Sbitset__fprint): Use it instead of %d. + +2009-09-27 Joel E. Denny + + tests: don't abuse AT_BISON_CHECK. + * tests/regression.at (parse-gram.y: LALR = IELR): Move + additional shell commands outside of AT_BISON_CHECK. + +2009-09-26 Joel E. Denny + + tests: check that parse-gram.y's IELR and LALR are identical. + * tests/atlocal.in (abs_top_srcdir): New shell variable. + * tests/regression.at (parse-gram.y: LALR = IELR): New test + group. + +2009-09-16 Akim Demaille + + doc: comment changes. + * doc/bison.texinfo: Comment changes. + +2009-09-16 Akim Demaille + + doc: spell checking. + * doc/bison.texinfo: here. + +2009-09-19 Alex Rozenman + + Keep sub-messages aligned.

Use new alignment mechanism. + * tests/named-ref.at: Adjust test-cases. + * NEWS (2.5): Add an announcement about named references. + +2009-09-13 Joel E. Denny + + tests: clean up push.at test group titles. + * tests/push.at: Remove "Push Parsing: " from test group titles + because these are already under the banner "Push Parsing Tests". + +2009-09-12 Alex Rozenman + + Provide an additional sub-message for clarity. + Add "symbol not found in production" error message when + an "invalid reference" is detected in named references + resolution. + * src/scan-code.l: Update "invalid reference" case. + * tests/named-ref.at: Adjust test-cases. + +2009-09-10 Joel E. Denny + + Clean up yacc.c a little. + * data/yacc.c: Clean up M4 for readability, and make output + whitespace more consistent.
