--- Comment #2 from Pedro Alves <palves at redhat dot com> --- Thanks for looking at that! I'd love for that patch to me merged, but realistically, I don't know when I'd have time to champion it, and it's been almost 3 years... If someone picks it up and runs with it, it's much appreciated. FYI, Jason provided feedback in the following month: https://gcc.gnu.org/ml/gcc-patches/2014-06/msg00082.html but I never followed through, and I have no other local changes.
