datadata StgToCmmConfig

Constructors

StgToCmmConfig
- 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

- 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.
