=> DynFlags
-> Module
-> ModLocation
-> NcgImpl statics instr jumpDest
-> UniqSupply
-> DwarfFiles

Fields

cmmTopCodeGen :: RawCmmDecl -> NatM [NatCmmDecl statics instr]
generateJumpTableForInstr :: instr -> Maybe (NatCmmDecl statics instr)
getJumpDestBlockId :: jumpDest -> Maybe BlockId
canShortcut :: instr -> Maybe jumpDest
shortcutStatics :: (BlockId -> Maybe jumpDest) -> statics -> statics
shortcutJump :: (BlockId -> Maybe jumpDest) -> instr -> instr
pprNatCmmDecl :: NatCmmDecl statics instr -> SDoc
maxSpillSlots :: Int
allocatableRegs :: [RealReg]
ncgExpandTop :: [NatCmmDecl statics instr] -> [NatCmmDecl statics instr]
ncgAllocMoreStack :: Int -> NatCmmDecl statics instr -> UniqSM (NatCmmDecl statics instr, [(BlockId, BlockId)])
The list of block ids records the redirected jumps to allow us to update the CFG.
ncgMakeFarBranches :: LabelMap CmmStatics -> [NatBasicBlock instr] -> [NatBasicBlock instr]
extractUnwindPoints :: [instr] -> [UnwindPoint]
given the instruction sequence of a block, produce a list of the block's UnwindPoints See Note [What is this unwinding business?] in Debug and Note [Unwinding information in the NCG] in this module.
invertCondBranches :: Maybe CFG -> LabelMap CmmStatics -> [NatBasicBlock instr] -> [NatBasicBlock instr]
Turn the sequence of `jcc l1; jmp l2` into `jncc l2; block_l1` when possible.
