[PATCH] D17474: MachineCopyPropagation: Keep scanning through instructions with regmasks

[Matthias Braun via llvm-commits]

MatzeB updated this revision to Diff 48855.
MatzeB added a comment.

New revision which splits SourceNoLongerAvailable() into two new functions: ClobberCopySources(), ClobberRegister() so the code that is now in ClobberCopySources() can be reused for the regmask case.
The tests have also been extended to cover negative cases and check for kill flag clearing.
