The changes in https://reviews.llvm.org/D38668 will prevent this issue from manifesting as a using __multi3 on x86. However, one might want to independently look at why licm and/or indvars produces a i65 mul (that gets promoted to i128) for the reduced test submitted by Eric. Generating large multiply instructions on some platforms may lead to less efficient code.
