ubsan: Avoid -Wpadded warnings [PR94641]
-Wpadded warnings aren't really useful for the artificial types that GCC
lays out for ubsan.
2020-04-21 Jakub Jelinek <jakub@redhat.com>
PR c/94641
* stor-layout.c (place_field, finalize_record_size): Don't emit
-Wpadded warning on TYPE_ARTIFICIAL rli->t.
* ubsan.c (ubsan_get_type_descriptor_type,
ubsan_get_source_location_type, ubsan_create_data): Set
TYPE_ARTIFICIAL.
* asan.c (asan_global_struct): Likewise.
* c-c++-common/ubsan/pr94641.c: New test.
