Denny + + Fix gcc 3.4.4 shadowing warning reported by Eric Blake. + See + . + * src/scan-code.h (code_props_rule_action_init): Rename + named_ref arg to name so it doesn't shadow named_ref type. This + makes it consistent with the function definition in scan-code.l + anyway. + +2009-08-28 Joel E. Denny + + %define: accept unquoted values. + * NEWS (2.5): Group all %define changes together, and document + this one.

Denny + + tests: use perl for printing special sequences to files. + And skip tests if perl is not available. This is better than + playing tricks with shell portability. Suggested by Akim + Demaille. + * tests/input.at (Bad character literals): Use it here for + omitting final newlines. + (Bad escapes in literals): Use it here for special characters. + +2009-08-26 Joel E.

Denny + + More fixes related to last two patches. + * data/c.m4 (b4_table_value_equals): Comment that YYID must be + defined. + * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix + yytable comments: zero indicates syntax error not default + action. + * data/glr.c (yyis_pact_ninf): Rename to... + (yypact_value_is_default): ... this. + (yyisDefaultedState): Update for rename. + (yyis_table_ninf): Rename to... + (yytable_value_is_error): ... this, and check for value zero + besides just YYTABLE_NINF. + (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.

No behavioral changes. + * src/tables.h: Improve comments about yypact, yytable, etc. + more. Most importantly, say yytable value of zero means syntax + error not default action. + +2009-08-25 Joel E.
