¶void emitCounterMapping(const clang::Decl* D,
                        llvm::raw_ostream& OS)

Description

Emit the coverage mapping data which maps the regions of code to counters that will be used to find the execution counts for those regions.

Declared at: clang/lib/CodeGen/CoverageMappingGen.h:168

Parameters

const clang::Decl* D

llvm::raw_ostream& OS

¶void emitEmptyMapping(const clang::Decl* D,
                      llvm::raw_ostream& OS)

Description

Emit the coverage mapping data for an unused function. It creates mapping regions with the counter of zero.

Declared at: clang/lib/CodeGen/CoverageMappingGen.h:172

Parameters

const clang::Decl* D

llvm::raw_ostream& OS
