llvm-cov -path-equivalence=/tmp,... is used by some checked-in coverage mapping files where the original filename is under /tmp. If the test itself produces the coverage mapping file, there is no need for /tmp. For coverage_emptylines.cpp: the source filename is under the build directory. If the build directory is under /tmp, the path mapping will make llvm-cov fail to find the file.
