Chris Lattner db6c348f31 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! llvm-svn: 120974		2010-12-06 01:48:06 +00:00
