Gyah... So it is. We put the stuff from -include into builtin_scope
and start the file scope only in __sparse().
See if adding
int is_outer_scope(struct scope *scope)
{
if (scope == block_scope)
return 0;
if (scope == &builtin_scope && block_scope->next == &builtin_scope)
return 0;
return 1;
}
to scope.c and replacing
sym = lookup_symbol(token->ident, NS_STRUCT);
if (!sym ||
(sym->scope != block_scope &&
(match_op(token->next,';') || match_op(token->next,'{'))))
{
with
sym = lookup_symbol(token->ident, NS_STRUCT);
if (!sym ||
(is_outer_scope(sym->scope) &&
(match_op(token->next,';') || match_op(token->next,'{'))))
{
in parse.c:struct_union_enum_specifier() would fix all problems of that kind.
