Use YYMAXDEPTH for maximum stack size given that + the stack should never need to grow larger than the main state + stack needs to grow without LAC. + (YY_LAC_ESTABLISH): Update yy_lac invocation. + (yy_lac): Add arguments for exploratory stack memory data + recorded in the main parser.

Denny + + yysyntax_error: adjust prior fixes for branch-2.5's lalr1.cc. + On master, there is no yychar in lalr1.cc, but there is on + branch-2.5, and the prior cherry-pick of "Fix handling of yychar + manipulation in user semantic actions" wasn't adjusted for that + difference. + * data/lalr1.cc (yy::parser::parse): Translate yychar before + every use of yytoken, and add comments explaining this approach. + * tests/conflicts.at (%error-verbose and consistent errors): + Extend to test yychar manipulation with lalr1.cc. + +2010-11-07 Joel E.

With that meaning of 1 gone, renumber + return codes more usefully. + (yyparse, yypush_parse): Update yysyntax_error usage. Most + importantly, set yytoken to YYEMPTY when there's no lookahead. + * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the + unexpected token unless there actually is no lookahead. + * data/lalr1.cc (yy::parser::parse): If there's no lookahead, + set yytoken to yyempty_ before invoking yysyntax_error_. + (yy::parser::yysyntax_error_): Again, don't drop the unexpected + token unless there actually is no lookahead. + * data/lalr1.java (YYParser::parse): If there's no lookahead, + set yytoken to yyempty_ before invoking yysyntax_error. + (YYParser::yysyntax_error): Again, don't drop the unexpected + token unless there actually is no lookahead. + * tests/conflicts.at (%error-verbose and consistent + errors): Extend test group to further reveal how the previous + use of the simple "syntax error" message was too general. Test + yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected + failure. + * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move + to... + * tests/local.at: ... here. + (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition. + (AT_BISON_OPTION_POPDEFS): Pop it. + (AT_FULL_COMPILE): Extend to handle Java. + +2010-11-07 Joel E.

Don't have time to look into why. + (gnulib_modules): Change malloc to malloc-gnu. Do we really assume + the GNU malloc behavior, where malloc (0) != NULL unless we're + out of storage? If not, we can omit malloc-gnu; but for now I left + it in to be safe. + (vc_ignore): Remove. + * README-hacking: Renamed from HACKING, since gnulib bootstrap now + uses that convention. + +2010-08-05 Joel E.
