size by the array amount as an i32 value instead of promoting from i32 to i64 then doing the multiply. Not doing this broke wrap-around assumptions that the optimizers (validly) made. The ultimate real fix for this is to introduce i64 version of alloca and remove mallocinst. This fixes PR3829 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67093 91177308-0d34-0410-b5e6-96231b3b80d8
