+
+ * src/reader.c (copy_at, copy_dollarm parse_braces, parse_action)
+ (parse_guard): Rename the formal argument `stack_offset' as
+ `rule_length', which is more readable.
+ Adjust callers.
+ (copy_at, copy_dollar): Instead of outputting the hard coded
+ values of $$, $n and so forth, output invocation to b4_lhs_value,
+ b4_lhs_location, b4_rhs_value, and b4_rhs_location.
+ Note: this patch partially drops `semantic-parser' support: it
+ always does `rule_length - n', where semantic parsers ought to
+ always use `-n'.
+ * data/bison.simple, data/bison.c++ (b4_lhs_value)
+ (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

+
+ * data/bison.simple: Remove unnecessary commentary and white
+ space differences from 1_29-branch.

+
+ (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
