+- `make check-stage1-rpass TESTNAME=<substring-of-test-name>` - Run a single
   rpass test with the stage1 compiler (this will be quicker than running the
   command above as we only build the stage1 compiler, not the entire thing).
   You can also leave off the `-rpass` to run all stage1 test types.
