Hi @yln, this is mostly for compiler-rt where one test could be tested in many configurations. That makes `llvm-lit /path/to/test/src/` does not work since the `config_map` maps test source code to only one configuration currently. This patch adds a third test suite marker file (lit.site.multi.cfg), `config_map` could map to and invoke all the test configs applicable to the test.
