[LLVMdev] Eliminating General Purpose Register

[Juan Carlos Martinez Santos]

Hello,

Sound odd, but how I can reduce the amount of GPR available. Is there a
place (file) where I let know the compiler how many register it can use?

I have planned to used some registers for special purpose, so I want to
estimate the cost before to do it. In my project, I cannot add register to
the current architecture (I will imply redesign my core - x86based).

Thanks in advance,
