RegAlloc.Graph.Main
Description
Graph coloring register allocator.
TODO: The colors in graphviz graphs for x86_64 and ppc could be nicer.
- regAlloc :: (PlatformOutputable statics, PlatformOutputable instr, Instruction instr) => DynFlags -> UniqFM (UniqSet RealReg) -> UniqSet Int -> [LiveCmmDecl statics instr] -> UniqSM ([NatCmmDecl statics instr], [RegAllocStats statics instr])

Arguments
| :: (PlatformOutputable statics, PlatformOutputable instr, Instruction instr) | |
| => DynFlags | |
