Subject: Ignore llvm.* globals.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2dc0d9bddb578f5ddf02495caf97a6281ee06fab;p=platform%2Fupstream%2Fllvm.git

Ignore llvm.* globals.

It is not clear if llvm.global_ctors should or should not be in llvm.metadata,
but in practice it is not and we need to ignore it for LTO.
