The DejaGnu design doesn't allow test discovery in general (as the set of tests can depend on the results of previous tests; tests are run through arbitrary Tcl code in .exp files which both enumerates them and runs them). Hopefully the GCC tests are well enough structured not to run into this problem. (Being able to enumerate tests separately from running them, and to run each test independently, is the QMTest model, though there are other issues with how that handles some things that come up in toolchain testing.) -- Joseph S.
