Stuart Hastings 7ac8f8f341 Avoid fusing bitcasts with dynamic allocas if the amount-to-allocate ... might overflow. Re-typing the alloca to a larger type (e.g. double) hoists a shift into the alloca, potentially exposing overflow in the expression. rdar://problem/9265821 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132926 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-13 18:48:49 +00:00
