[PATCH] D16434: Fix LivePhysRegs::addLiveOuts

[Weiming Zhao via llvm-commits]

weimingz retitled this revision from " Fix ARM load/store opt live reg computing" to " Fix LivePhysRegs::addLiveOuts".
weimingz updated the summary for this revision.
weimingz removed rL LLVM as the repository for this revision.
weimingz updated this revision to Diff 45741.
weimingz added a comment.

I think originally the problem was covered because epilogue will do the job. Now with shrink-wrap, it is exposed.
