[LLVMdev] problems with the legalizer
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
