llvm dev - Oct 2019 - How to run single compiler-rt test in monorepo?

Hello all,
  I am having trouble running only a single lit-based test of compiler-rt.
My folder structure is: inside the llvm monorepo checkout, I have a dir
"build" with subdir "buildtrunk". I ran cmake inside
"buildtrunk" and also
run ninja from there.

For LLVM I can do the following:
> cd build/buildtrunk/test
> ../bin/llvm-lit  --show-tests .
And it shows all tests discovered of the llvm main library, but not tests
of for example clang or compiler-rt.
Running a single test works aswell:
> ../bin/llvm-lit -v tools/yaml2obj/versym-section.yaml
-- Testing: 1 tests, 1 workers --
PASS: LLVM :: tools/yaml2obj/versym-section.yaml (1 of 1)
...

However whatever I try, I have not succeeded in having Lit discover the
compiler-rt tests, and I didn't manage to run just one compiler-rt test.
Information online is sparse, and I didn't find it there either.

What is are command / How do I run a single lit-based compiler-rt test?

Thanks a lot,
  Johan

I usually run single tests (compiler-rt and LLVM) as
LIT_FILTER=<testname> ninja check-<component>

It's also possible to run lit on a test directory that's constructed
within the build dir, e.g.:

~/src/builds/llvm-project-master-RA (0) $ ./bin/llvm-lit
projects/compiler-rt/test/profile/Profile-x86_64h/instrprof-basic.c
