[LLVMdev] Implementing select_cc without cmov

Hi All,

I need to implement select_cc as a "cmp; mov rX,1; brcond cnd, END;
mov rX,0; END:" sequence.

Chris mentioned that the PPC code (as well as the x86 SSE code) does
this, but I can't seem to find it.

What I really need to kmow is how to insert the branch/label pair at
instruction selection phase.

Anyone have an example of this?
