GHC.CmmToAsm.Reg.Linear.State

Constructors

• RA_State
  • ra_blockassig :: BlockAssignment freeRegs

    the current mapping from basic blocks to the register assignments at the beginning of that block.

  • ra_freeregs :: !freeRegs

    free machine registers

  • ra_assig :: RegMap Loc

    assignment of temps to locations

  • ra_delta :: Int

    current stack delta

  • ra_stack :: StackMap

    free stack slots for spilling

  • ra_us :: DUniqSupply

    unique supply for generating names for join point fixup blocks.

  • ra_spills :: [SpillReason]

    Record why things were spilled, for -ddrop-asm-stats. Just keep a list here instead of a map of regs -> reasons. We don't want to slow down the allocator if we're not going to emit the stats.

  • ra_config :: !NCGConfig

    Native code generator configuration

  • ra_fixups :: [(BlockId, BlockId, BlockId)]

    (from,fixup,to) : We inserted fixup code between from and to
