Yes, this is becoming much more urgent, assuming we'll be raising the
minimum GCC version soon and drop support for lacking asm-goto...

Do you happen to know who the right people are to include to move the
discussion forward? I know various kernel folks that are passionate
about it, but I'm still getting to know who to talk with from llvm.

I see an earlier thread here:
http://lists.llvm.org/pipermail/llvm-dev/2017-April/111748.html

It seems to end there? I'm still coming up to speed on it, so I'm
likely missing other context.
