--- Comment #5 from Jeffrey A. Law <law at redhat dot com> ---
I can't see how a REG_EQUAL note on an insn with multiple outputs can possibly
work -- we wouldn't know what output the REG_EQUAL note refers to. And we have
to consider an embedded side effect as having an output.
Or to think of it another way, any embedded side effect can be implemented with
a parallel at which point it's painfully obvious the insn has multiple outputs
and a REG_EQUAL note would be inappropriate.
