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.

| CoverageData CoverageMapping::getCoverageForExpansion | ( | const ExpansionRecord & | Expansion | ) | const |
Get the coverage for an expansion within a coverage set.
Definition at line 1485 of file CoverageMapping.cpp.
References llvm::dbgs(), Expansion, isExpansion(), and LLVM_DEBUG.
| CoverageData CoverageMapping::getCoverageForFile | ( | StringRef | Filename | ) | const |
Get the coverage for a particular file.
The given filename must be the name as recorded in the coverage information. That is, only names returned from getUniqueSourceFiles will yield a result.

Get the coverage for a particular function.

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 992 of file CoverageMapping.h.
| std::vector< InstantiationGroup > CoverageMapping::getInstantiationGroups | ( | StringRef | Filename | ) | const |
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.

References findMainViewFileID().

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This is a count of functions whose profile is out of date or otherwise can't be associated with any coverage information.
Definition at line 986 of file CoverageMapping.h.
| std::vector< StringRef > CoverageMapping::getUniqueSourceFiles | ( | ) | const |
Returns a lexicographically sorted, unique list of files that are covered.

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.
