Hi.  Yeah, it is broken.  Bitrot.
I fixed a few issues, and still have a few more to look into.

Does anyone have docs on the m32rx ISA?  I can find m32r ISA docs from 
the Renesas link on the main webpage, but I need m32rx.  The f-accs 
field is 2 bits yet there are only 2 h/w accumulators.  This should be 
flagged at .cpu load time, but it's currently crashing gas-test.

btw, here's how I'm testing gas-test.

bash$ cd src/cgen
bash$ guile
guile> (load "dev.scm")
guile> (load-gtest)
guile> (cload #:arch "../cpu/m32r.cpu") ; replace with path to your cpu 
file of course
guile> (cgen-build.sh)
guile> (cgen-all-insn.exp)

That should run without any errors.

Also, to get a backtrace when invoking gas-test from the command line:

bash$ make gas-test CGENFLAGS='-v -b'
