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 llvm-svn: 67093
