Re: Reserving a number of consecutive registers
Ok, I've been working at this and have actually made a bit of progress.
- I now have a framework that finds the group of loads (let's assume
they stay together).
- With the DF framework, I'm able to figure out which registers are
being used and which are free to be used.
- I've pretty much got it to change the registers to the ones I want
but there are still some corner cases where it seems to be badly
handling that and actually changing the semantics of the program.
I'll look into that, thanks,
