m0 is treated as a virtual register class with a single register rather than the physical register it really is. This was updating the live range of the used virtual copy of m0 from the first ds_read instruction, and leaving the unused copy unchanged. This resulted in a "Live segment doesn't end at a valid instruction" verifier error because the erased instructions. Update the live range of the second copy (which should be dead). No test since I'm not sure how to trigger this with SIFoldOperands enabled. llvm-svn: 223203 |
