Re: Determining live registers on Cmm procedure entry?

t is to change CmmProc to include live register info. If this turns out to be too painful I may go back to the bitcast idea. Cheers, David On 16 October 2012 03:45, Geoffrey Mainland wrote: Hi all, I'm working on changing GHC's calling convention to support overlapping register class

Determining live registers on Cmm procedure entry?

Hi all, I'm working on changing GHC's calling convention to support overlapping register classes. On x86-64 this will mean that a function can receive up to six Float/Double arguments (any mixture) in registers. Right now only two Double arguments can be passed in registers on x86-64, even if
