[PATCH] D13361: Support for emitting inline stack probes

[Reid Kleckner via llvm-commits]

rnk added a comment.

I think it'd be cleaner to avoid changing the target independent TargetFrameLowering interface, and instead keep it as an X86-internal pseudo instruction that we lower in X86ExpandPseudo.cpp. Then PEI doesn't have to worry about this MBB expansion issue. What do you think?

I think the `WIN_ALLOCA` pseudo instruction can probably just take on that new role, and we could rename it to something more accurate like `CHKSTK`.
