[LLVMdev] Emitting PPC branches

[Brent Monroe]

Hi,

I want to take an intrinsic function, and get the PowerPC back
end to emit:

loop:  lwarx  ...
       add    ...
       stwcx. ...
       bne- loop

I can successfully emit:

lwarx  ...
add    ...
stwcx. ...

How do I emit a label and a branch instruction?

Thanks,

Brent
