[PATCH] D42171: X86CallFrameOptimization: Bail on win64cc calls

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

I think the problem is that passing aggregates to ms_abi functions in wine is broken. It generates invalid MIR. There's a bug for that somewhere (http://llvm.org/PR31362). I'd just dupe this bug against that and leave it alone. As long as the call optimization code doesn't optimize call sequences that have gaps it will naturally ignore win64cc functions.
