--0-587994391-1551275541=:4073 Content-Type: text/plain; CHARSET=UTF-8 Content-Transfer-Encoding: 8BIT Hi Tijl, hi everyone, and let me add Andreas who has been helping on the GCC side (both ports, viz. his work on arm and powerpc, and upstream) and toolchain@! And first of all, let me apologize. Clearly the experience both Tijl as a contributor made, as well as the one some of our users including some of you was not what I'd like to experience myself as a contributor and user, nor what I want to provide to others. There were some personal reasons, not related to Tijl or FreeBSD at all, but that does not change a thing about those experiences, and I am truely sorry for those and will work hard to avoid such a case in the future.

To move this forward, let me include an updated version of the patch Tijl shared on 2017-02-21 (which still was in my inbox/todo list) for consideration for our ports collection, initially for lang/gcc8 given that this is the default in the ports collection. (The lang/gcc* ports actually do carry local patches, e.g. for arm or powerpc or -fuse-ld=lld, but you are right that I usually try to get things upstream first, fixing things upstream myself when I can, or asking for help. The problem in this specific case was/is that I'm quite not enough into this area so cannot really assess and clearly stalling over that was not good.) Find patch-gfortran-libgcc attached which should simply plug into lang/gcc8/files and lang/gcc8-devel/files. Feedback very welcome!
