I have hit a extreme case during a bootstrap. The DAG combiner canonicalizes <= 65536 into < 65537 The problem is that 65536 can de represented inline in a ARM instruction and 65537 cannot. I am considering changing the code that creates ARMCMP when lowering br_cc and set_cc nodes. Does anyone has a better solution? Best Regards, Rafael

I am attempting to lower the selectCC instruction to the instruction set of the backend I'm working on and I cannot seem to find a way to correctly implement this instruction. I know how this instruction should get implemented; I just have yet to find a way to do it. I want the select_cc instruction to be lowered into a comparison followed by a conditional move. I've attempted to use a
