Errors like the following are reported by: https://urldefense.proofpoint.com/v2/url?u=http-3A__lab.llvm.org-3A8011_builders_llvm-2Dclang-2Dx86-5F64-2Dexpensive-2Dchecks-2Dwin_builds_11261&d=DwIBAg&c=5VD0RTtNlTh3ycd41b3MUw&r=DA8e1B5r073vIqRrFz7MRA&m=929oWPCf7Bf2qQnir4GBtowB8ZAlIRWsAdTfRkDaK-g&s=9k-wbEUVpUm474hhzsmAO29VXVvbxJPWD9RTgCD71fQ&e= *** Bad machine code: Explicit definition marked as use *** - function: cal_align1 - basic block: %bb.0 entry (0x47edd98) - instruction: LDB $r3, $r2, 0 - operand 0: $r3 This is because RegState info was missing for ScratchReg inside expandMEMCPY. This caused incomplete register usage information to MachineInstr verifier which then would complain as there could be potential code-gen issue if the complained MachineInstr is used in place where register usage information matters even though the memcpy expanding is not in such case as it happens at the last stage of IR optimization pipeline. We should always specify those register usage information which compiler couldn't deduct automatically whenever we add a hardware register manually.
