--- Comment #34 from Iain Sandoe <iains at gcc dot gnu.org> --- I did ask for OK on back-ports We should let it bake on master for now - I see reports that 12.1 ia under test - but no idea when it will come out (or if this particular issue will be fixed in it). In any event, it was designed to be an add-on so that the behaviour of everything else (that does not set the target option) would be unchanged - so IMO it would be safe to use the back ported patch ahead of "reality" in emergency.
