[LLVMdev] backend question
Thank you very very much for your answer!
Am I correct in my understanding that "let Defs = [CPSR]" in the definition
of AI1_bin_s_irs multiclass explains the effect of setting conditional codes

Sincerely,

I'm just starting to work on a backend for a custom cpu. For some
instructions this cpu has two flavors: first performs an operation, and the

instruction adds the contents of register rs to register rd and places the
result in rd; add.cc rd, rs
