I have been wondering about conditional execution - can this be used for
a processor that has only a limited set of conditionally executable
things.
On the Calmrisc16, there are conditional jump indirect and return insn
(where the latter is really a special case of the former at the hardware
and assembler level).
OTOH we can't use a return pattern till reload has compled, so that we
know what registers need saving / restoring.
