OK I have taken a while to reply to this, so that I could put some factual input. * The Darwin port(s) [x86 and ppc] are primarily maintained on a volunteer basis, which means progress is slow and sporadic. * For my part, I tend to prioritise fixes that will work across the whole Darwin range (which, in practical terms, means powerpc,i686-darwin9 … x86_64-darwin16). [Corresponding to OS X 10.5 => 10.12] * I usually test : x86_64-darwin1x (currently 15), powerpc-darwin9, i686-darwin10 (and sometimes x86_64-darwin10). * With lots of help from Segher and Bill (Schmidt), I do try to keep the PowerPC port afloat and actually 5.x/6.x is not in bad shape - it’s possible to build powerpc-darwin9 toolchains capable of building ~ 120 OSS projects including some of the more demanding ones (e.g. LLVM). 5.4.0: https://gcc.gnu.org/ml/gcc-testresults/2017-01/msg02969.html 6.3.0: https://gcc.gnu.org/ml/gcc-testresults/2017-01/msg02970.html trunk: * There are a small number of bootstrap fixes needed to trunk (attached to the test-results, for interest). * Sadly, trunk seems to have regressed for powerpc-darwin9 significantly in the last few weeks, I had clean Ada tests (at least for revision 242913, late November, and likely later), but don’t have time to track this down right now. https://gcc.gnu.org/ml/gcc-testresults/2017-01/msg02971.html Hopefully that helps clarify where we’re at presently, Iain
