# Documentation

initCostCentres :: CollectedCCs -> FCode () Source #

ccType :: Platform -> CmmType Source #

ccsType :: Platform -> CmmType Source #

mkCCostCentre :: CostCentre -> CmmLit Source #

mkCCostCentreStack :: CostCentreStack -> CmmLit Source #

initInfoTableProv :: [CmmInfoTable] -> InfoTableProvMap -> Module -> FCode CStub Source #

emitInfoTableProv :: InfoProvEnt -> FCode () Source #

dynProfHdr :: Profile -> CmmExpr -> [CmmExpr] Source #

Profiling header words in a dynamic closure

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

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

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

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 :: Profile -> CostCentreStack -> [CmmLit] Source #

The profiling header words in a static closure

initUpdFrameProf :: CmmExpr -> FCode () Source #

Initialise the profiling field of an update frame

enterCostCentreThunk :: CmmExpr -> FCode () Source #

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

costCentreFrom :: Platform -> CmmExpr -> CmmExpr Source #

storeCurCCS :: CmmExpr -> CmmAGraph Source #

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

saveCurrentCostCentre :: FCode (Maybe LocalReg) Source #

restoreCurrentCostCentre :: Maybe LocalReg -> FCode () Source #

ldvEnter :: CmmExpr -> FCode () Source #

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

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 () Source #
