Fields

• stgToCmmProfile :: !Profile

  Current profile

• stgToCmmThisModule :: Module

  The module being compiled. This field kept lazy for Cmm/Parser.y which preloads it with a panic

• stgToCmmTmpDir :: !TempDir

  Temp Dir for files used in compilation

• stgToCmmContext :: !SDocContext

  Context for StgToCmm phase

• stgToCmmEmitDebugInfo :: !Bool

  Whether we wish to output debug information

• stgToCmmBinBlobThresh :: !(Maybe Word)

  Threshold at which Binary literals (e.g. strings) are either dumped to a file and a CmmFileEmbed literal is emitted (over threshold), or become a CmmString Literal (under or at threshold). CmmFileEmbed is only supported with the NCG, thus a Just means two things: We have a threshold, and will be using the NCG. Conversely, a Nothing implies we are not using NCG and disables CmmFileEmbed. See Note [Embedding large binary blobs] in GHC.CmmToAsm.Ppr, and cgTopBinding in GHC.StgToCmm.

• stgToCmmMaxInlAllocSize :: !Int

  Max size, in bytes, of inline array allocations.

• stgToCmmDoTicky :: !Bool

  Ticky profiling enabled (cf -ticky)

• stgToCmmTickyAllocd :: !Bool

  True indicates ticky prof traces allocs of each named thing in addition to allocs _by_ that thing

• stgToCmmTickyLNE :: !Bool

  True indicates ticky uses name-specific counters for join-points (let-no-escape)

• stgToCmmTickyDynThunk :: !Bool

  True indicates ticky uses name-specific counters for dynamic thunks

• stgToCmmTickyTag :: !Bool

  True indicates ticky will count number of avoided tag checks by tag inference.

• stgToCmmLoopification :: !Bool

  Loopification enabled (cf -floopification)

• stgToCmmAlignCheck :: !Bool

  Insert alignment check (cf -falignment-sanitisation)

• stgToCmmOptHpc :: !Bool
