insn-recog.c contains a giant decision tree all spelled out in C.
Back in 1999 rth and I got about halfway done with a patch to
implement it using a bytecode interpreter instead.  This gave ~10x
size reduction and no measurable performance difference.  That's the
patch I'm working on again now.

When i resurrected this patch a year or so ago (after you sent it to me, if you don't remember), I got it working somewhat, and *did* notice a performance difference, so i gave up on it.

The size reduction was about 10x, however.
