Fields

• [LocalReg]

  Put result(s) in these regs and fall through NB: no void arguments here

• Bool

  Should we adjust the heap pointer back to recover space that's unused on this path? We need to do this only if the expression may allocate (e.g. it's a foreign call or allocating primOp)

Fields

• sli_id :: !Id
   
• sli_arity :: !RepArity

  always equal to idFunRepArity of sli_id, i.e. unarised arity, including void arguments

• sli_registers :: ![LocalReg]

  Excludes void arguments (LocalReg is never void)

• sli_header_block :: !BlockId
   

Fields

• virtHp :: VirtualHpOffset
   
• realHp :: VirtualHpOffset
   

Fields

• cg_id :: Id

  Id that this is the info for

• cg_lf :: LambdaFormInfo
   
• cg_loc :: CgLoc

  CmmExpr for the *tagged* value

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.

• stgToCmmTickyTag :: !Bool

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