https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=201623 --- Comment #6 from Mark Millard <markmi@dsl-only.net> --- (In reply to Mark Millard from comment #4) A clang status update: clang 4 and clang 5 are better behaved for TARGET_ARCH=powerpc . There is a problem if clang built the system library code involved in handling thrown C++ exceptions (process crash). But there was a fix to the system ld to fix clang-based C++ exception operation when the system libraries are built by gcc (such as the system gcc 4.2.1 compiler): Roman Divacky rdivacky at freebsd.org wrote on Sat Oct 7 10:03:10 UTC 2017 : > In a followup to https://lists.freebsd.org/pipermail/freebsd-toolchain/2017-May/002961.html > > I attempted to fix gnu ld in base to fix the wrongly set bit. > > The following patch > http://www.vlakno.cz/~rdivacky/ppc64.exceptions.fix.patch > > switches a few computations to happen in 64bits instead of 32bit and fixes the > wrong personality/LDSA info in binaries. > > As a result clang compiled/assembled c++ binaries with EH start to work for me. > > Can someone verify this works for everyone?
