Denny + + Fix handling of yychar manipulation in user semantic actions. + 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. + +2009-12-21 Joel E.
