Thanks, lgtm!

In PR43614 I mentioned adding an extra argument to llvm-cov to specify the base directory. On second thought, the existing `-path-equivalence` option should make that unnecessary.



================
Comment at: clang/test/CoverageMapping/debug-dir.cpp:14
+//
+// RELATIVE: @__llvm_coverage_mapping = {{.*"\\01[^/]*foobar.*debug-dir\.cpp}}

----------------
Does the "[^/]" check work on Windows, or is something like "[^/\\]" necessary?
