CostCentre

Synopsis

Documentation

data CostCentre Source #

A Cost Centre is a single {--} annotation.

Fields

  • cc_flavour :: CCFlavour

    Two cost centres may have the same name and module but different SrcSpans, so we need a way to distinguish them easily and give them different object-code labels. So every CostCentre has an associated flavour that indicates how it was generated, and flavours that allow multiple instances of the same name and module have a deterministic 0-based index.

  • cc_name :: CcName

    Name of the cost centre itself

  • cc_mod :: Module

    Name of module defining this CC.

  • cc_loc :: SrcSpan

data CostCentreStack Source #

A Cost Centre Stack is something that can be attached to a closure. This is either:

  • the current cost centre stack (CCCS)
  • a pre-defined cost centre stack (there are several pre-defined CCSs, see below).

isSccCountCC :: CostCentre -> Bool Source #

Is this a cost-centre which records scc counts

sccAbleCC :: CostCentre -> Bool Source #

Is this a cost-centre which can be sccd ?

pprCostCentreCore :: CostCentre -> SDoc Source #

Print a flavour in Core
