Deciding whether to put a testcase

[Kazu Hirata]

Hi,

On machines with variable length insns, it's important to write
correct length (or worst case length) in a machine description because
failure to do so might cause a short jump to be generated even though
a long jump is needed.

Now, do I need to submit a testcase for this kind of bug?  This is so
target specific, and I don't know if it's OK to flood testsuite with
tests of this kind.

Thanks,
