| | | | | | | * data/lalr1.cc (yy::parser::yysyntax_error_): Always add second argument, but name it in the function definition only when verbose error messages are enabled and it'll thus be used. (yy::parser::parse): Update use of yysyntax_error_.
* Fix handling of yychar manipulation in user semantic actions.Joel E. Denny2009-12-221-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was that yacc.c didn't always update the yychar translation afterwards. However, other skeletons appear to be fine. glr.c appears to already translate yychar before every use. lalr1.cc does not define yychar and does not document its replacement, yyla, for users. It does provide yyclearin, but that does not manipulate yyla and thus requires no translation update. In lalr1.java, yychar is out of scope during semantic actions. * NEWS (2.5): Document. * data/yacc.c (YYBACKUP): Don't bother translating yychar into yytoken here. (yyparse, yypush_parse): Instead, translate before every use of yytoken, and add comments explaining this approach. * tests/actions.at (Destroying lookahead assigned by semantic action): New test group checking that translation happens before lookahead destructor calls at parser return. Previously, incorrect destructors were called. * tests/conflicts.at (%error-verbose and consistent errors): New test group checking that translation happens at syntax error detection before the associated verbose error message and the associated lookahead destructor calls. While the destructor call is fixed by this patch, the verbose error message is currently incorrect due to another bug (see comments in test group), so this is an expected failure for now.

* yysyntax_error: avoid duplicate lookahead collection.Joel E. Denny2009-10-041-67/+75
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

(yygetLRActions): Check for default value from yypact. It appears that this check is always performed before this function is invoked, and so adding the check here is probably redundant. However, the code may evolve after this subtlety is forgotten. Also, update for rename to yytable_value_is_error. Because that macro now checks for zero, a different but equivalent branch of the if-then-else here is evaluated. (yyreportSyntaxError): Update for rename to yytable_value_is_error.

* Fix strange %define locations for default values.Joel E. Denny2009-04-031-6/+5
| | | | | | | | | | | | | | | | | | Reported by Akim Demaille at <http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html> and discussed again starting at <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>. * data/bison.m4 (b4_percent_define_default): Leave syncline blank because location information is bogus. Use angle brackets to delimit fake file name because square brackets look like over-quoted m4. Choose a better fake file name. Use negative line numbers. * src/muscle_tab.c (muscle_percent_define_default): Likewise. * src/location.c (location_print): If line for a boundary is negative, only print that boundary's file name. * src/location.h: Document that. * tests/skeletons.at (%define Boolean variables: invalid skeleton defaults): Update output.
* lalr1.cc: avoid GCC 4.3 warnings.Akim Demaille2009-03-261-8/+9
| | | | | | | | | | GCC 4.3 now warns about "a || b && c" and asks for explicit parentheses. Reported by Alexandre Duret-Lutz. * data/location.cc: Update copyright years. (Position::operator==): Use parens to make precedence explicit. Compare lines and columns first, as they are more likely to be different, and they are faster to compare.
