Now, really.  I don't see how it could be much simpler, save
for not writing any files at all.

Do I understand correctly that you have tests in
gas/testsuite/gas/avr but that they aren't run?

Doing "make check 'RUNTESTFLAGS=-v -v'" should give you more
info, but I think that's mentioned in the dejagnu manual, so you
should already be aware of that step...

This is a good time to read all manuals and have a good look at
the source code.  Lots of info is in the installed dejagnu, at
/usr or /usr/local share/dejagnu

How else do you expect to swim?  Really.

No, you don't have to do this, the framework does it for you.
What I said should be all that's needed.  Did you change all
mmix-* to avr-*?

I have no idea.  Using an old tcl or expect version?

Usually people build in a directory other than where the source
is.  Maybe you don't do that and there are issues with running
the testsuite in the source directory.
