Re: preparing for GCC 4.9
Hello and apologies for the cross-post, I've built GCC 4.9 on my PowerMac G5 (ppc64) running Debian 7.3. I'd like to support the port of Debian to this platform using GCC 4.9 and would appreciate a pointer on where to begin if possible. Additionally, I could provide a SSH login to the machine.

If anything goes well, and a large amount of build failures are fixed, I plan to make GCC 4.9 the default for the C/C++/ObjC/Obj-C++ frontends at the end of May, beginning of June. Bugs reports for packages building with a legacy version of GCC (4.6, 4.7, 4.8) will be filed.

I tested to build kernel for Loongson 3 with gcc-4.9. it works fine.

I rebuilt 105 source packages on kfreebsd-amd64 comprising minbase and build-essential (except for GCC itself) using GCC 4.9 and did not notice any new build failures introduced by it. I'll continue to check that the binaries compiled by GCC 4.9 are actually okay. The issue with running the GCC testsuite on kfreebsd-amd64 buildds is being fixed by FreeBSD upstream, and on Debian buildds within 1-2 weeks.

Hi Matthias et al, I'd like to try to do some of this using my sparc box and see how far I get. Is there a link that explains how to set up these steps?

I set a build farm with gcc-4.9 for mips64el. It works well: it has no more failures than your amd64 one. All the buildlogs can be found in http://mips.wicp.net:9998/mips2/buildlog/ I noticed ctpp2 failed due to symbols problems on both amd64(pbuilder) and mips64el(sbuild). It seems that you didn't report bug on it. > > I'll work on fixing the build failures in [2], help is of course appreciated. > Almost all build failures are analyzed and should be easy to fix (exceptions > e.g. #746883).
