John David Anglin <dave.anglin@nrc-cnrc.gc.ca>
* config/vax/vax.h (CASE_DROPS_THROUGH): Don't define.
* config/vax/vax.md (casesi): Emit a test-and-branch to make sure
that the case is in range, to make sure the casesi insn is always
in range and never falls through.
(casesi1): Add comment to explain why casesi never falls through.
Remove the unnamed special case casesi pattern.
