+
+ In the grammar file, the first column is 1 not 0 on the first line as
+ on every other line.
+ * src/parse-gram.y (%initial-action): Initialize @$ correctly.
+ * tests/input.at (Torturing the Scanner): Update output.
+
+ * src/scan-gram.l (scanner_cursor): Declare it static.

+
+ In warnings, say "previous declaration" rather than "first
+ declaration".
+ * src/symtab.c (redeclaration): Do that here.
+ * src/reader.c (record_merge_function_type): In the case of a result
+ type clash, report the previous declaration rather than the very first
+ one in the grammar file.
+ * tests/glr-regression.at (Missed %merge type warnings when LHS type is
+ declared later): Add a third declaration to check this behavior.
+ * tests/input.at (Incompatible Aliases): Update output.

+ * doc/Doxyfile.in: New.
+ * doc/Makefile.am: Use it.
+ * src/lalr.h, src/symtab.h: Initial doxygenation.

+
+ Don't miss %merge result type warnings just because the LHS types are
+ declared after the %merge. This continues the effort of the previous
+ patch.
+ * src/reader.c (get_merge_function): Don't set the merger type yet.
+ (record_merge_function_type): New function for setting the merger type
+ and checking for clashes.
+ (grammar_current_rule_merge_set): Set the location of the %merge for
+ the current rule.
+ (packgram): Invoke record_merge_function_type for each rule now that
+ all symbol type declarations have been parsed.
+ * src/reader.h (merger_list.type_declaration_location): New member
+ storing the location of the first %merge from which the type for this
+ merging function was derived.
+ * src/symlist.h (symbol_list.merger_declaration_location): New member
+ storing the location of a rule's %merge, if any.
+ * tests/glr-regression.at (Missed %merge type warnings when LHS type is
+ declared later): New test to catch the error fixed by the above patch.

+
+ Get action warnings (grammar_rule_check) right even when symbol
+ declarations appear after the rules. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
+ Don't mistake the type of $$ in a midrule to be that of its parent
+ rule's $$.
+ * src/reader.c (grammar_current_rule_end): Don't invoke
+ grammar_rule_check yet since not all symbol declarations may have been
+ parsed yet.
+ (grammar_midrule_action): Likewise.
+ Don't record whether the midrule's $$ has been used yet since actions
+ haven't been translated yet.
+ Record the midrule's parent rule and its RHS index within the parent
+ rule.
+ (grammar_current_rule_action_append): Don't translate the action yet
+ since not all symbol declarations may have been parsed yet and, thus,
+ warnings about types for $$, $n, @$, and @n can't be reported yet.
+ (packgram): Translate the action and invoke grammar_rule_check now that
+ all symbol declarations have been parsed.
+ * src/scan-code.l (handle_action_dollar): Now that this is invoked
+ after parsing the entire grammar file, the symbol list here in the case
+ of a midrule is actually the midrule's empty RHS, so reference its
+ parent rule's RHS where necessary.
+ On the other hand, now that you can already know it's a midrule, you
+ aren't forced to think $$ has the same type as its parent rule's $$.
+ (handle_action_at): In the case of a midrule, reference the parent rule
+ where necessary.
+ * src/symlist.c (symbol_list_new): Initialize new midrule-related
+ members.
+ (symbol_list_length): Now that this is invoked after all rules have
+ been parsed, a NULL symbol (rather than a NULL symbol list node)
+ terminates a rule. symbol_list_print already does this correctly.
+ * src/symlist.h (symbol_list.midrule_parent_rule,
+ symbol_list.midrule_parent_rhs_index): New members so that midrules can
+ remember their relationships with their parents.
+ * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
+ fixed by the above patch.
+ (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
+ implementing...
+ (Unused values): ... this old test case and...
+ (Unused values before symbol declarations): ... this new test case.
+ This one is the same as `Unused values' except that all symbol
+ declarations appear after the rules in order to catch the rest of the
+ errors fixed by the above patch.
