+
+2009-09-03 Joel E. Denny <jdenny@clemson.edu>
+
+ Don't suppress warnings about unused parse.error.
+ * data/bison.m4 (b4_error_verbose_flag): Don't examine value of
+ %define variable parse.error unless b4_error_verbose_flag is

+
+2009-09-03 Akim Demaille <demaille@gostai.com>
+

+ * 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.

+ Avoid compiler warning.
+

+
+ 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 <jdenny@clemson.edu>
+
+ tests: show a use of %define lr.default-reductions "consistent"
+ * tests/conflicts.at (%nonassoc and eof): Extend to test that it
+ prevents the omission of expected tokens for %error-verbose.
+
+2009-08-26 Akim Demaille <demaille@gostai.com>
+
+ tests: portability fix.
+ * tests/input.at (Bad escapes in literals): Don't expect "echo
+ '\0'" to output \ then 0.
+
+2009-08-26 Joel E. Denny <jdenny@clemson.edu>
+
+ Actually handle the yytable zero value correctly this time.
+ * data/bison.m4 (b4_integral_parser_tables_map): Don't mention
+ zero values in the YYTABLE comments.
+ * data/glr.c (yytable_value_is_error): Don't check for zero
+ value.
+ * data/lalr1.cc (yy_table_value_is_error_): Likewise.
+ * data/yacc.c (yytable_value_is_error): Likewise.
+ * data/lalr1.java (yy_table_value_is_error_): Likewise.
+ (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
+ * src/tables.h: In header comments, explain why it's useless to
+ check for a zero value in yytable.
