Author: emaste (src committer) Date: Tue Dec 19 18:06:29 2017 New Revision: 456743 URL: https://svnweb.freebsd.org/changeset/ports/456743 Log: devel/libunwind: set LLD_UNSAFE libunwind.so has symbols with ELF protected visibility which various test applications could preempt. Both GNU gold and LLVM's lld fail to link this case, with errors like lld: /usr/bin/ld: error: cannot preempt symbol: _ULx86_64_init_local >>> defined in ../src/.libs/libunwind.so >>> referenced by Lperf-trace.c >>> Lperf-trace.o:(main) gold: /usr/local/bin/ld.gold: error: Gperf-simple.o: cannot make copy relocation for protected symbol '_Ux86_64_local_addr_space', defined in ../src/.libs/libunwind-x86_64.so For now prevent libunwind from linking with lld.
