If the source of the copy that defines the addend is a physical register, then its existing live range may not extend to the FMA being mutated. Make sure we extend the live range of the register to meet the FMA because it will become its operand in this case. I don't have an independent test case, but it will be exposed by change to be committed shortly enabling the use of the machine combiner to do fadd/fmul reassociation, and will be covered by one of the associated regression tests. llvm-svn: 242278 |
