...tter way to invalidate the MBBI iterator? Basic blocks aren't that long (on average 4-6 instructions) and this peephole isn't that common either. -------------- next part -------------- An HTML attachment was scrubbed...

This seems a very natural approach but I probably am having a trouble with the iterator invalidation. However, looking at other peephole optimizers passes, I couldn't see how to do this: #define BUILD_INS(opcode, new_reg, i) \ BuildMI(*MBB, MBBI, MBBI->getDebugLoc(), TII->get(X86::opcode)) \ .addReg(X86::new_reg, kill).addImm(i) for
