Eh... What is your current reality and why don't I see the
problem you see for cris-elf that warrants marking it as broken?

There was a build issue before for sim/cris, but it's been fixed
to the best of my knowledge. (FWIW in a hackish way, but with
the same effect to the generated sim/cris files as a proper fix.
The proper fix has been ok'd by fche FWIW, I just haven't
regened all CGEN files for all other simulators and tested them;
it's kind of low-priority.) That issue seems to match what you
allude to by "(sim/cris/modelv10.c:4181
crisv10f_engine_run_full?)"

I build sim/cris just now (beware, cutnpaste with wrapping):
/tmp/hptmp/src/configure --target=cris-axis-elf && make all
... in short, no problems.

I also built with gdb_mbuild.sh same host, no problems:
...
cris-elf ...
... /tmp/hptmp/src/configure --target=cris-elf --enable-gdb-build-warnings=,-Werror --enable-sim-build-warnings=,-Werror
... make cris-elf
... run cris-elf
... cleanup cris-elf
... cris-elf built
...

Of course, that was with this obvious patch to make
gdb_mbuild.sh build cris-elf (at least it *seemed* necessary):

And that's a gcc-3.4 on a i686:

gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)

I've also build with the configure line above (in a gcc-combined
tree) on x86_64-unknown-linux-gnu (FC4t2, which uses a
gcc-4.0-derivate: gcc-4.0.0-2). No problems. Same thing on i686
FC2, (gcc-3.3.3-7) no problems.

What problem do you see and on what host, and have you updated
since Mar 24 with no local patches, at least none related to the
cris-elf build issue mentioned above?
