- Subject: generating compare and branch instructions
I'm trying to figure out how to tell GCC in the machine description
file how to:
- use any register for the result of the cmpsi instruction
- alternatively, emit a single instruction for compare & branch
Any pointers?
Does any of the existing backends do something similar?
