          Issue ID: 21054
           Summary: Test Suite test/run.d has no documentation on how the
                    dmd under test is specified
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: bugzilla at digitalmars.com

I cannot find in test/run.d where it decides which dmd to run the tests on. The
emitted output is "..." for which compiler is run, which is useless. Couldn't
find it in test/README.md, either.

Even using the -v switch doesn't produce useful information.
