  • 72f000b088 * NEWS: Bison-generated C parsers no longer quote literal strings associated with tokens. * src/output.c (prepare_symbols): Don't escape strings, since users don't want to see C escapes. * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes in diagnostics. * tests/regression.at (Token definitions, Web2c Actions): Likewise. Paul Eggert 2005-04-17 08:07:15 +00:00
  • 1094323fe4 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if the data size is known to be too small and we can't increase it. Paul Eggert 2005-04-16 08:11:52 +00:00
  • f79b4f5ce1 (AT_INCREASE_DATA_SIZE): Skip the test if the data size is known to be too small and we can't increase it. Paul Eggert 2005-04-16 08:11:33 +00:00

  • ca407bdf9d * src/parse-gram.y: Include quotearg.h. (string_as_id): Quote $1 before using it as a key, since the lexer no longer quotes it for us. (string_content): Don't strip quotes, since lexer no longer quotes it for us. * src/scan-gram.l: Include quotearg.h. ("\""): Omit quote. ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as a key, since the rest of the lexer doesn't quote it. * src/symtab.c (symbol_get): Don't quote symbol; caller does it now. * tests/regression.at (Token definitions): Check for backslashes in token strings. Paul Eggert 2005-04-16 06:32:51 +00:00
  • 506ffb1f74 (YYSTACK_ALLOC_MAXIMUM): New macro. (YYSIZE_T): Define to unsigned long int when using an older compiler. (yyparse): Revamp code to generate long syntax error message, to make it easier to translate, and to avoid problems with arithmetic overflow. Change "virtual memory" to "memory" in diagnostic, since we don't know whether the memory is virtual. Paul Eggert 2005-04-16 06:25:03 +00:00

  • 1ce590705a * NEWS: Bison-generated C parsers now use the _ macro to translate strings. * data/yacc.c (_) [!defined _]: New macro. All English strings wrapped inside this macro. * doc/bison.texinfo (Bison Parser): Document _. * po/POTFILES.in: Include src/parse-gram.c, since it now includes translateable strings that parse-gram.y doesn't.

  • d7e14fc000 * NEWS: Bison-generated parsers no longer default to using the alloca function (when available) to extend the parser stack, due to widespread problems in unchecked stack-overflow detection. * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's responsibility to set it to a positive value. This lets the user specify a value that is not a preprocessor constant. * data/yacc.c (YYMAXDEPTH): Likewise. (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero. * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs to be a compile-time constant. However, explain the constraints on it.

(parser::parse): Return ints, not bool. Returning a bool introduces a problem: 0 corresponds to false, and it seems weird to return false on success. Returning true changes the conventions for yyparse. Alternatively we could return void and send an exception. There is no clear consensus (yet?). (state_stack, semantic_stack, location_stack): Rename as... (state_stack_type, semantic_stack_type, location_stack_type): these.
