Function Documentation

branchDiv()

uint32_t branchDiv ( uint64_t Numerator, uint64_t Divisor )

static

Definition at line 569 of file GCOV.cpp.

formatPercentage()

uint32_t formatPercentage ( uint64_t dividend, uint64_t divisor )

static

Definition at line 559 of file GCOV.cpp.

mangleCoveragePath()

std::string mangleCoveragePath ( StringRef Filename, bool PreservePaths )

static

Convert a path to a gcov filename.

If PreservePaths is true, this translates "/" to "#", ".." to "^", and drops ".", to match gcov.
