From: Aaron Sawdey Date: Tue, 17 Nov 2020 23:17:44 +0000 (-0600) Subject: Additional small changes to support opaque modes X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1e2d8575ace4e12dbe95ae2d4a49a4d89c6f67eb;p=gcc.git Additional small changes to support opaque modes After building some larger codes using opaque types and some c++ codes using opaque types it became clear I needed to go through and look for places where opaque types and modes needed to be handled. A whole pile of one-liners. gcc/ * typeclass.h: Add opaque_type_class. * builtins.c (type_to_class): Identify opaque type class. * dwarf2out.c (is_base_type): Handle opaque types. (gen_type_die_with_usage): Handle opaque types. * expr.c (count_type_elements): Opaque types should never have initializers. * ipa-devirt.c (odr_types_equivalent_p): No type-specific handling for opaque types is needed as it eventually checks the underlying mode which is what is important. * tree-streamer.c (record_common_node): Handle opaque types. * tree.c (type_contains_placeholder_1): Handle opaque types. (type_cache_hasher::equal): No additional comparison needed for opaque types. gcc/c-family * c-pretty-print.c (c_pretty_printer::simple_type_specifier): Treat opaque types like other types. (c_pretty_printer::direct_abstract_declarator): Opaque types are supported types. gcc/c * c-aux-info.c (gen_type): Support opaque types. gcc/cp * error.c (dump_type): Handle opaque types. (dump_type_prefix): Handle opaque types. (dump_type_suffix): Handle opaque types. (dump_expr): Handle opaque types. * pt.c (tsubst): Allow opaque types in templates. (unify): Allow opaque types in templates. * typeck.c (structural_comptypes): Handle comparison of opaque types. --- diff --git a/gcc/builtins.c b/gcc/builtins.c index a75b24c5492..40e77c7bf40 100644 --- a/gcc/builtins.c +++ b/gcc/builtins.c @@ -2228,6 +2228,7 @@ type_to_class (tree type) case ARRAY_TYPE: return (TYPE_STRING_FLAG (type) ? string_type_class : array_type_class);
