Hmm, it should be fairly trivial to update cgraph virtual cloning code to
actually handle those attributes...

--- Comment #3 from Martin Jambor <jamborm at gcc dot gnu.org> 2012-03-19 18:00:58 UTC ---
Confirmed as recently as this February? How can that be? I have just
checked that the testcase from PR 43665, comment #8 and verified the
checkoptimal subroutine is cloned and constants are propagated into
it, despite it having fnspec type attributes. If you have a testcase
where you believe fnspec attributes are the reason for not performing
IPA-CP, then please post it here, I'd certainly like to have a look.
Having said that, it is certainly true that the new IPA-CP accomplish
this by simply not deleting the newly-unused parameters, whereas
arguably it should update the fnspec attributes instead. If you think
that is something we should have a PR for, please change the
description accordingly, or open a new PR.
Otherwise I'll close this next week as a WORKSFORME.
(On a related and personal note, I dislike the representation of the
fnspec attributes very much, I think we should move it to the actual
parm_decls or to the call graph or someplace, updating a string_cst
just feels like a work-around.)
