GHC.HsToCore.Ticks

Synopsis

Documentation

Configuration for compilation pass to add tick for instrumentation to binding sites.

Constructors

TicksConfig
Fields ticks_passes :: ![TickishType] What purposes do we need ticks for ticks_profAuto :: !ProfAuto What kind of {-# SCC #-} to add automatically ticks_countEntries :: !Bool Whether to count the entries to functions Requires extra synchronization which can vastly degrade performance.

Constructors

Tick
Fields tick_loc :: SrcSpan Tick source span tick_path :: [String] Path to the declaration tick_ids :: [OccName] Identifiers being bound tick_label :: BoxLabel Label for the tick counter

Reasons why we need ticks,

Constructors

ProfNotes	For profiling
HpcTicks	For Haskell Program Coverage
Breakpoints	For ByteCode interpreter break points
SourceNotes	For source notes

Arguments

:: Logger
-> TicksConfig
-> Module
-> ModLocation	location of the current module
-> NameSet	Exported Ids. When we call addTicksToBinds, isExportedId doesn't work yet (the desugarer hasn't set it), so we have to work from this set.
-> [TyCon]	Type constructors in this module
-> LHsBinds GhcTc
-> IO (LHsBinds GhcTc, Maybe (FilePath, SizedSeq Tick))
