Hello all PowerPC users, As of r356113 (__FreeBSD_Version 1300070) Clang is now the default compiler for all PowerPC targets. At this time, powerpcspe requires extra patches available on https://reviews.llvm.org/ D69483 and D69484, as well as explicitly specifying the TARGET_TRIPLE=3Dpowerpc-unknown-freebsd13.0 and LLVM_TARGET_TRIPLE=3Dpowerpc-unknown-freebsd13.0. (I would like to hear from anyone who *is* using FreeBSD on a powerpcspe platform, off-list). As mentioned before, the powerpc64 change is also a change to the new ELFv2 ABI, which is binary incompatible with the previous ABI. Therefore, it is recommended to perform a complete reinstall of the system on powerpc64 platforms. I would like to thank Alfredo Dal'Ava J=C3=BAnior for all his efforts getting us to this point, as well as Brandon Bergren on system and kernel work, and Piotr Kubaj, and Mark Linimon for getting ports into shape for the transition. Anyone else I forgot, I do apologize, this has been a long effort, with many involved. - Justin
