Documentation

data CostCentre Source #

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

Constructors

NormalCC
Fields cc_key :: !Int 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 a Unique that is distinct from every other CostCentre in the same module. XXX: should really be using Unique here, but we need to derive Data below and there's no Data instance for Unique. cc_name :: CcName Name of the cost centre itself cc_mod :: Module Name of module defining this CC. cc_loc :: SrcSpan cc_is_caf :: IsCafCC
AllCafsCC
Fields 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).
