The RECORD_TYPE doesn't have lang specific payload allocated for it.
There is no point why we need to describe that in the debug info though.
So I'd do something like:
2012-11-12 Jakub Jelinek <ja...@redhat.com>
* asan.c (report_error_func): Set DECL_IGNORED_P, don't touch
DECL_ASSEMBLER_NAME.
(asan_init_func): Likewise.
(asan_finish_file): Use void * instead of __asan_global * as
type of __asan_{,un}register_globals. Set DECL_IGNORED_P on
the decls.
