https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206990 --- Comment #13 from Mark Millard <markmi@dsl-only.net> --- (In reply to Dimitry Andric from comment #10) I got a notice of the latest fix for covering the TARGET_ARCH=3Dpowerpc stack-handling issues for llvm bugzilla 26519: Comment # 33 on bug 26519 from Krzysztof Parzyszek The fix has been committed in master in r303257. I opened PR33070 to request merging it into 4.0.1. You are receiving this mail because: =E2=80=A2 You reported the bug. I've been using a version of the patch for some time and for buildworld it appears that with it powerpc and powerpc64 have a similar status: the one known area not working is handling of thrown C++ exceptions --for example the required dwarf information is incomplete so such programs crash handling thrown exceptions. As for buildkernel use for powerpc (32-bit): powerpc FreeBSD with a clang 4 based kernel build on the same machines fails at the /sbin/init attempt and then gets an alignment exception. (I've not tried a G4 or G3 yet.) But booting the kernel seems to work up to that point. Both the buildworld and the buildkernel results are great improvements for targeting 32-bit powerpc FreeBSD via clang. --=20 You are receiving this mail because: You are the assignee for the bug.=
