Andrew Trick 2be0fae98c Track register pressure a bit more carefully (weird corner case). ... This solves a problem where a def machine operand has no uses but has not been marked dead. In this case, the initial RP analysis was being extra precise and determining from LiveIntervals the the register was actually dead. This caused us to omit the register from the RP tracker's block live out. That's all good, but the per-instruction summary still accounted for it as a valid def. This could cause an assertion in the tracker later when we underflow pressure. This is from a bug report on an out-of-tree target. It is not reproducible on well-behaved targets. I'm just making an obvious fix without unit test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200941 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-06 19:20:41 +00:00
