The mapping of profile information to coverage data.

This is the main interface to get coverage information, using a profile to fill out execution counts.

ArrayRef< std::pair< std::string, uint64_t > > llvm::coverage::CoverageMapping::getHashMismatches ( ) const inline

A hash mismatch occurs when a profile record for a symbol does not have the same hash as a coverage mapping record for the same symbol.

This returns a list of hash mismatches, where each mismatch is a pair of the symbol name and its coverage mapping hash.

Definition at line 1059 of file CoverageMapping.h.

◆ getInstantiationGroups()

Get the list of function instantiation groups in a particular file.

Every instantiation group in a program is attributed to exactly one file: the file in which the definition for the common function begins.

◆ getMismatchedCount()

unsigned llvm::coverage::CoverageMapping::getMismatchedCount ( ) const inline

The number of functions that couldn't have their profiles mapped.

This is a count of functions whose profile is out of date or otherwise can't be associated with any coverage information.

◆ getUniqueSourceFiles()

std::vector< StringRef > CoverageMapping::getUniqueSourceFiles ( ) const

◆ load() [1/2]

◆ load() [2/2]

Load the coverage mapping from the given object files and profile.

If Arches is non-empty, it must specify an architecture for each object. Ignores non-instrumented object files unless all are not instrumented.
