shortcutStatics :: (BlockId -> Maybe JumpDest) -> (Alignment, RawCmmStatics) -> (Alignment, RawCmmStatics) Source #
allocMoreStack :: Platform -> Int -> NatCmmDecl statics Instr -> UniqSM (NatCmmDecl statics Instr, [(BlockId, BlockId)]) Source #
maxSpillSlots :: NCGConfig -> Int Source #
archWordFormat :: Bool -> Format Source #
takeRegRegMoveInstr :: Instr -> Maybe (Reg, Reg) Source #
Check whether an instruction represents a reg-reg move. The register allocator attempts to eliminate reg->reg moves whenever it can, by assigning the src and dest temporaries to the same real register.
regUsageOfInstr :: Platform -> Instr -> RegUsage Source #
Returns which registers are read and written as a (read, written) pair.
takeDeltaInstr :: Instr -> Maybe Int Source #
See if this instruction is telling us the current C stack delta
mkJumpInstr :: BlockId -> [Instr] Source #
Make an unconditional branch instruction.
jumpDestsOfInstr :: Instr -> [BlockId] Source #
patchRegsOfInstr :: Instr -> (Reg -> Reg) -> Instr Source #
Applies the supplied function to all registers in instructions. Typically used to change virtual registers to real registers.
isMetaInstr :: Instr -> Bool Source #
isJumpishInstr :: Instr -> Bool Source #
