.\" $FreeBSD$
Set to use LLVM's libunwind stack unwinder (instead of GCC's unwinder).
Support use of LLVM's libunwind for exception unwinding It is built in libgcc_s.so and libgcc_eh.a to simplify transition. It is enabled by default on arm64 (where we previously had no other unwinder) and may be enabled for testing on other platforms by setting WITH_LLVM_LIBUNWIND in src.conf(5). Also add compiler-rt's __gcc_personality_v0 implementation for use with the LLVM unwinder.
