Hi,
shared.s segfaults on my machine (FreeBSD). The buildbot didn't
complain tho, so it may just be a local problem. Anyway, maybe more
careful investigation is due.

% /exps/llvm-lld/build/bin/lld -flavor gnu2 -shared
/exps/llvm-lld/build/tools/lld/test/elf2/Output/shared.s.tmp2.o -o
/exps/llvm-lld/build/tools/lld/test/elf2/Output/shared.s.tmp2.so
Segmentation fault (core dumped)

Program received signal SIGSEGV, Segmentation fault.
