Member Functions

Name

Description

InstrProfReader [constructor]

Construct a default instrprof reader with no open profile.

~InstrProfReader [destructor] [virtual]

Destroy the reader.

accumulateCounts

Compute the sum of counts and return in Sum.

begin

Iterator over profile data.

end

Return an end iterator for the profile data.

functionEntryOnly [virtual]

Return true if the profile only instruments function entries.

getError

Get the current error.

getProfileKind [virtual]

Returns a BitsetEnum describing the attributes of the profile. To check individual attributes prefer using the helpers above.

getSymtab [virtual]

Return the PGO symbol table.

getTemporalProfTraceStreamSize

Return the total number of temporal profile traces seen.

getTemporalProfTraces [virtual]

Return the temporal profile traces.

getVersion [virtual]

Return the profile version.

hasCSIRLevelProfile [virtual]

Return true if this is a context‐sensitive IR‐level profile.

hasError

Return true if the reader encountered an error reading profiling data.

hasMemoryProfile [virtual]

Return true if profile includes a memory profile.

hasSingleByteCoverage [virtual]

Return true if the profile has single byte counters representing coverage.

hasTemporalProfile [virtual]

Return true if this has a temporal profile.

instrEntryBBEnabled [virtual]

Return true if the profile instruments function entries.

instrLoopEntriesEnabled [virtual]

Return true if the profile instruments all loop entries.

isEOF

Return true if the reader has finished reading the profile data.

isIRLevelProfile [virtual]

Return true if this is an IR‐level instrumentation profile.

printBinaryIds [virtual]

Print binary ids.

readBinaryIds [virtual]

Read a list of binary ids.

readHeader [virtual]

Read the header. Required before reading first record.

readNextRecord [virtual]

Read a single record.
