  BTW, although you've already fixed this: I wouldn't expect to see any of the
RUNTESTFLAGS you pass on the commandline ending up in the site.exp in any
case.

  Ow, that's a bit "quirky and individualistic" :)

  Looks like it's progressing nicely.

  Most of the tests in the gcc testsuite are pretty lightweight on stack
usage, but there are a few big ones.  I use this in my board.exp:

# We only have a small stack available to us
set_board_info gcc,stack_size 2048

to try and avoid running the excessive ones.

  I also have an old patch kicking around that adds a whole load of extra
"set_board_info no_XXXXX" options that are useful in small embedded systems
where you don't have a full runtime, stdio, signals, etc. etc.; it cuts out a
whole load of the noise from the list of FAILs.  Let me know if you'd like a
copy.

  One random other thing, I have this line in my board.exp:

# The simulator isn't really remote.
set_board_info isremote 0

  I think you'll need that as well.

    cheers,
