Chris Lattner cc10244d77 Fix PR8728, a miscompilation I recently introduced. When optimizing ... memcpy's like: memcpy(A, B) memcpy(A, C) we cannot delete the first memcpy as dead if A and C might be aliases. If so, we actually get: memcpy(A, B) memcpy(A, A) which is not correct to transform into: memcpy(A, A) This patch was heavily influenced by Jakub Staszak's patch in PR8728, thanks Jakub! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120974 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-06 01:48:06 +00:00
