Add check + for leaked parent RHS values. + * data/glr.c (yydestroyGLRState): In debugging output, distinguish + between an unresolved state (non-empty chain of semantic options) and + an incomplete one (signaled by an empty chain). + (yyresolveStates): Document the interface. Move all manipulation of a + successfully or unsuccessfully resolved yyGLRState to... + (yyresolveValue): ... here so that yyresolveValue always leaves a + yyGLRState with consistent data and thus is easier to understand. + Remove the yyvalp and yylocp parameters since they are always just + taken from the yys parameter. When reporting a discarded merged value + in debugging output, note that it is incompletely merged. Document the + interface. + (yyresolveAction): If resolving any of the RHS states fails, destroy + them all rather than leaking them. Thus, as long as user actions are + written to clean up the RHS correctly, yyresolveAction always cleans up + the RHS of a semantic option. Document the interface. + +2006-02-27 Paul Eggert + + * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that + led to a segmentation fault in GNU Pascal. Problem reported + by Waldek Hebisch. + +2006-02-21 Joel E. Denny + + * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a + mid-rule action inside a nonterminal symbol in order to declare a + destructor for its semantic value. + 2006-02-16 Paul Eggert * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
