[PATCH] D79589: [WIP] syndicate code generation between dynamic alloca and static alloca during stack clash probing

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa added a comment.

I think this was actually @uweigands suggestion, but for now we are going to first try to make sure that the prologue is as fast as possible and not combine the reg/imm case. But it will be interesting to know if you can get the prologue code equally fast this way...

I also wonder if the X86 backend is adding the live-in list entries on the new MBBs in inlineStackProbe(). I discovered that I had to call recomputeLiveIns() on the new blocks (SystemZ patch is updated, so you can see what I mean there...)
