Author: dim Date: Sat Apr 29 23:26:36 2017 New Revision: 317599 URL: https://svnweb.freebsd.org/changeset/base/317599 Log: MFC r317214: Turn off llvm/clang's ENABLE_BACKTRACES setting, since it never worked properly anyway. (Upstream has reorganized this somewhat in the mean time, but for proper backtraces we would need llvm-symbolizer in base.) MFC r317215: Add function and data sections when building llvm, clang, lld and lldb, and allow the linker to garbage collect them. This shaves off up to a few MB from the final executables.
