virtualRegSqueeze :: RegClass -> VirtualReg -> FastInt
regSqueeze_class reg Calculuate the maximum number of register colors that could be denied to a node of this class due to having this reg as a neighbour.
realRegSqueeze :: RegClass -> RealReg -> FastInt
classOfRealReg :: RealReg -> RegClass
allRealRegs :: [RealReg]
All the allocatable registers in the machine, including register pairs.
allocatableRegs :: [RealReg]
Produce the second-half-of-a-double register given the first half.
All the regs that the register allocator can allocate to, with the the fixed use regs removed.
The registers to place arguments for function calls, for some number of arguments.
allArgRegs :: [Reg]
All all the regs that could possibly be returned by argRegs
callClobberedRegs :: [Reg]
mkVirtualReg :: Unique -> Size -> VirtualReg
Make a virtual reg with this size.
regDotColor :: RealReg -> SDoc
