Arnold Schwaighofer 9b5d70f076 LoopVectorize: Use the widest induction variable type ... Use the widest induction type encountered for the cannonical induction variable. We used to turn the following loop into an empty loop because we used i8 as induction variable type and truncated 1024 to 0 as trip count. int a[1024]; void fail() { int reverse_induction = 1023; unsigned char forward_induction = 0; while ((reverse_induction) >= 0) { forward_induction++; a[reverse_induction] = forward_induction; --reverse_induction; } } radar://13862901 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181667 91177308-0d34-0410-b5e6-96231b3b80d8		2013-05-11 23:04:28 +00:00
