initCostCentres :: CollectedCCs -> FCode () #

ccType :: DynFlags -> CmmType #

ccsType :: DynFlags -> CmmType #

mkCCostCentre :: CostCentre -> CmmLit #

mkCCostCentreStack :: CostCentreStack -> CmmLit #

dynProfHdr :: DynFlags -> CmmExpr -> [CmmExpr] #

Profiling header words in a dynamic closure

profDynAlloc :: SMRep -> CmmExpr -> FCode () #

Record the allocation of a closure. The CmmExpr is the cost centre stack to which to attribute the allocation.

profAlloc :: CmmExpr -> CmmExpr -> FCode () #

Record the allocation of a closure (size is given by a CmmExpr) The size must be in words, because the allocation counter in a CCS counts in words.

staticProfHdr :: DynFlags -> CostCentreStack -> [CmmLit] #

The profiling header words in a static closure

initUpdFrameProf :: CmmExpr -> FCode () #

Initialise the profiling field of an update frame

enterCostCentreThunk :: CmmExpr -> FCode () #

enterCostCentreFun :: CostCentreStack -> CmmExpr -> FCode () #

costCentreFrom :: DynFlags -> CmmExpr -> CmmExpr #

curCCS :: CmmExpr #

storeCurCCS :: CmmExpr -> CmmAGraph #

emitSetCCC :: CostCentre -> Bool -> Bool -> FCode () #

saveCurrentCostCentre :: FCode (Maybe LocalReg) #

restoreCurrentCostCentre :: Maybe LocalReg -> FCode () #

ldvEnter :: CmmExpr -> FCode () #

ldvEnterClosure :: ClosureInfo -> CmmReg -> FCode () #

Called when a closure is entered, marks the closure as having been "used". The closure is not an "inherently used" one. The closure is not `IND` because that is not considered for LDV profiling.

ldvRecordCreate :: CmmExpr -> FCode () #
