Can't that be done by having a parent pass to hold them, with a gate
function?
Or are you thinking of having another domain-specific language?
Thinking aloud, I've sometimes wondered if it would be helpful to be
able to subclass pass_manager, so that multiple passes.def files could
generate alternative pass_manager subclasses, with the precise choice of
pass_manager subclass being determined by options+target. I don't know
if that latter idea is useful though.
