the cgen code doesn't seem to issue very useful error messages.

Any suggestions on how to track down this problem?


cgen -s /export/home/lehotsky/basel/sim/tpc/../../cgen/cgen-sim.scm -s /export/home/lehotsky/basel/sim/tpc/../../cgen -v -f with-profile=fn -m tpc -a tpc -i all -C tmp-cpu.h1 -U tmp-cpu.c1 -M tmp-mod.c1 -S tmp-sem.c1 -T tmp-dec.h1 -D tmp-dec.c1 -S tmp-sem.c1

I looked at the theory that maybe one of my instruction
defines didn't describe a "32 bit" instruction.  But every one of
them lays out the full 32 bits of each fixed-length instruction.
