This is the everything diff: it includes the clang diff that I sent to tech@, plus the major version bumps for libLLVM libc++ libc++abi.
- distrib/sets/lists: put the new versions in the base sets. - gnu/llvm/tools/clang: -msvr4-struct-return - gnu/usr.bin/clang/libLLVM, lib/libcxx, lib/libcxxabi: new versions Index:
