Config map is not exposed through the command line, so testing this is somewhat tricky. But basically we need a test that if a custom driver builds a config map and passes it to main, it gets respected. A config map allows config files in the source tree to be mapped to alternate config files in the build tree. This particular test works by having two config files in separate directories, and setting up a config map to have that redirects A/lit.site.cfg to B/altconfig. Then, we print a message in A/lit.site.cfg and B/altconfig and check that we do see the output from B but don't see the output from A. Additionally we test that the test suite specified by A's config map is properly discovered. Differential Revision: https://reviews.llvm.org/D38105 llvm-svn: 313887
