Detailed Description

This namespace defines accessors shared by different versions of coverage mapping records.

Function Documentation

advanceByOneOutOfLine()

template<class FuncRecordTy , llvm::endianness Endian>

std::pair< const char *, const FuncRecordTy * > llvm::coverage::accessors::advanceByOneOutOfLine	(	const FuncRecordTy *	Record,
		const char *	MappingBuf
	)

Advance to the next out-of-line coverage mapping and its associated function record.

Definition at line 1180 of file CoverageMapping.h.

getCoverageMappingOutOfLine()

template<class FuncRecordTy , llvm::endianness Endian>

StringRef llvm::coverage::accessors::getCoverageMappingOutOfLine	(	const FuncRecordTy *	Record,
		const char *	MappingBuf
	)

Read coverage mapping out-of-line, from MappingBuf.

This is used when the coverage mapping is attached to the file header, instead of to the function record.

Definition at line 1171 of file CoverageMapping.h.

getDataSize()

template<class FuncRecordTy , llvm::endianness Endian>

uint64_t llvm::coverage::accessors::getDataSize

(

const FuncRecordTy *

Record

)

Return the coverage map data size for the function.

Definition at line 1147 of file CoverageMapping.h.

getFuncHash()

template<class FuncRecordTy , llvm::endianness Endian>

uint64_t llvm::coverage::accessors::getFuncHash

(

const FuncRecordTy *

Record

)

Return the structural hash associated with the function.

Definition at line 1141 of file CoverageMapping.h.

getFuncNameRef()

template<class FuncRecordTy , llvm::endianness Endian>

uint64_t llvm::coverage::accessors::getFuncNameRef

(

const FuncRecordTy *

Record

)

Return the function lookup key. The value is considered opaque.

Definition at line 1153 of file CoverageMapping.h.

getFuncNameViaRef()

template<class FuncRecordTy , llvm::endianness Endian>

Error llvm::coverage::accessors::getFuncNameViaRef	(	const FuncRecordTy *	Record,
		InstrProfSymtab &	ProfileNames,
		StringRef &	FuncName
	)

Return the PGO name of the function.

Used for formats in which the name is a hash.

Definition at line 1160 of file CoverageMapping.h.
