llvm dev - Jun 2007 - [LLVMdev] If conversion scope

Hi,

This is directly mostly at Evan, but I thought the answer would be  
generally useful.

Could you describe how general in scope the target independent  
IfConversion/predecation infrastructure is?

Is it aimed only at architectures which support generalized  
predicated execution, or is there an opportunity to use this on  
architectures that only support predicated moves?

LLVM has select instructions that can / should be isel'd to  
conditional moves. The post-regallocation if converter is for targets  
that support some form of generalized predication.
