signed multiplication is requested. While there is not a difference in the *low* half of the result, the *high* half (used specifically to implement the signed division by these constants) certainly is used. The test case I've nuked was actively asserting wrong code. There is a delightful solution to doing signed multiplication even when we don't have it that Richard Smith has crafted, but I'll add the machinery back and implement that in a follow-up patch. This at least restores correctness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214007 91177308-0d34-0410-b5e6-96231b3b80d8
