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.
