Andrew Trick e74c2e86cb Fix SCEV forgetMemoizedResults should search and destroy backedge exprs. ... Fixes PR15570: SEGV: SCEV back-edge info invalid after dead code removal. Indvars creates a SCEV expression for the loop's back edge taken count, then determines that the comparison is always true and removes it. When loop-unroll asks for the expression, it contains a NULL SCEVUnknkown (as a CallbackVH). forgetMemoizedResults should invalidate the loop back edges expression. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177986 91177308-0d34-0410-b5e6-96231b3b80d8		2013-03-26 03:14:53 +00:00
