[LLVMdev] problems with the legalizer

[Rafael Espíndola]

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
