Hi Jeff,

In the gencodes.c:89, it explicitly  decrements by one the return
value of get_num_insn_codes(). While for the get_num_insn_codes is
stated this:

/* Return the number of possible INSN_CODEs.  Only meaningful once the
    whole file has been processed.  */

I can provide an example for the ARC port where it crashes due to
LAST_INSN_CODE issue. Probably it can be reproduced with other more
popular port like ARM.
Passing along a test, even for the ARC is useful.

This is something Richard recently changed, it's probably just an oversight on his part. I believe he's in the UK and may be offline for the day.
