Summary: This pragma is very rare. We could *hypothetically* lower some uses of it down to @llvm.global_ctors, but given that GlobalOpt isn't able to optimize prioritized global ctors today, there's really no point. If we wanted to do this in the future, I would check if the section used in the pragma started with ".CRT$XC" and had up to two characters after it. Those two characters could form the 16-bit initialization priority that we support in @llvm.global_ctors. We would have to teach LLVM to lower prioritized global ctors on COFF as well. This should let us compile some silly uses of this pragma in WebKit / Blink. Reviewers: rsmith, majnemer Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D4549 llvm-svn: 213593
