First two problems reported by Michael Deutschmann in + . + + * src/parse-gram.y (symbol_declaration): Don't put statements + before declarations; it's not portable to C89. + * src/scan-code.l (handle_action_at): Likewise. + + * src/scan-code.l: Always initialize braces_level; the old code + left it uninitialized and therefore had undefined behavior. + + Don't attempt to redefine 'assert', since it runs afoul of + systems where standard headers (mistakenly) include . + Instead, define and use our own alternative, called 'aver'. + * src/reader.c: Don't include assert.h, since we no longer + use assert. + * src/scan-code.l: Likewise. + * src/system.h (assert): Remove, replacing with.... + (aver): New function, taking a bool arg. All uses changed. + * src/tables.c (pack_vector): Ensure that aver arg is bool, + not merely an integer. + +2006-09-15 Bob Rossi + + * data/Makefile.am (dist_pkgdata_DATA): Add push.c. + * data/c.m4 (YYPUSH): New. + (b4_push_if): New macro. Use it instead of #ifdef YYPUSH. + * src/getargs.c (push_parser): New var. + * src/getargs.h (push_parser): New declaration. + * src/output.c (prepare): Add macro insertion of `push_flag'. + * src/parse-gram.y (PERCENT_PUSH_PARSER): New token. + (prologue_declaration): Parse %push-parser. + * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token. + * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to + list of removed lines from the traces observed. + (AT_CHECK_CALC_LALR): Added push parser tests. + +2006-09-13 Paul Eggert + + * NEWS: Version 2.3a. + * configure.ac (AC_INIT): Likewise. + + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove + "#define YYSTYPE int" that caused "make maintainer-check" to fail + due to header ordering dependencies. I don't know why the #define + was there. + + Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero + runtime cost when YYDEBUG is not defined, and so that some tests + that used to fail now work. Problem and initial suggestion by + Paolo Bonzini. + * data/c++.m4 (b4_parse_param_cons): Omit leading ','. + * data/glr.cc (b4_parser_class_name): + Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_. + (debug_level, set_debug_level): Affect yydebug_, not ::yydebug. + (yydebug_) [YYDEBUG]: New member. + (yycdebug_): Now defined only if YYDEBUG. + * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG. + (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_. + (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only + if YYYDEBUG. + (debug_stream, set_debug_stream, debug_level, set_debug_level): + Define only if YYDEBUG. + * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to + set_debug_level. + * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise. + * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to + AT_CHECK_CALC_GLR_CC that are working now. + +2006-09-12 Paul Eggert + + * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove. + We don't need them in glr.cc, and glr.c defines them. + Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c + assumes that defining it to anything is the same as defining + it to 1. Problem reported by Paolo Bonzini. + +2006-09-12 Paolo Bonzini (tiny change) + + * data/c.m4 (b4_null, b4_case): Define. + * src/output.c (prepare_symbols): Use b4_null. + (user_actions_output): Use b4_case. + 2006-09-11 Paul Eggert + * data/glr.c (b4_shared_declarations): Put start-header first, + before any #includes that we generate, so that feature-test + macros work. Problem reported by Michael Deutschmann in + . + * data/lalr1.cc: Likewise. + * doc/bison.texinfo (Prologue): Document that feature-test macros + should be defined before any Bison declarations. + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns + that depend on location.hh after, not before, Bison decls, since + we now include location.hh after the first user prologue. + * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by Sander Brandenburg in . Also, fix minor white space and comment issues. + (Prologue): Mention that it's better to define feature-test macros + before Bison declarations. Problem reported by Michael Deutschmann. + + * README-cvs: Fix typo: "&" should be "&&". Problem reported + by Jim Meyering. + * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4. + This adjusts to recent gnulib changes. 2006-09-04 Joel E. Denny
