[LLVMdev] Graph coloring register allocator for the x86
Hi all,
I was looking at the register allocator code and had a question about
that:
CodeGen/RegAlloc/PhysRegAlloc.cpp implements a graph coloring register
allocator for the Sparc back end. It requests target machine register
information via a call to getRegInfo() which returns a class
TargetRegInfo containing the required information. For the x86 target
machine, this interface has not been implemented. Is an implementation
of a x86-specific TargetRegInfo class the only piece of the puzzle
missing for a graph coloring x86 allocator? Or are there other issues
that need to be considered for...
