> why does it require a parameter for X86::COND_B? I changed that parameter in an experimental patch, and it didn't alter the asm.

I believe there is some code in lowering that uses it. I think it made it easier to handle it along with X86ISD::SETCC if it has a condition code operand in the same place.
