ΒΆint DiffFilesWithTolerance(
    llvm::StringRef FileA,
    llvm::StringRef FileB,
    double AbsTol,
    double RelTol,
    std::string* Error = nullptr)

Description

DiffFilesWithTolerance - Compare the two files specified, returning 0 if the files match, 1 if they are different, and 2 if there is a file error. This function allows you to specify an absolute and relative FP error that is allowed to exist. If you specify a string to fill in for the error option, it will set the string to an error message if an error occurs, or if the files are different.
