data CostCentre

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

Constructors

NormalCC

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

AllCafsCC

Fields

• cc_mod :: Module

  Name of module defining this CC.

• cc_loc :: SrcSpan

data CostCentreStack

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).
