Author: dim Date: Sun Feb 11 14:31:05 2018 New Revision: 324855 URL: http://llvm.org/viewvc/llvm-project?rev=324855&view=rev Log: Add default C++ ABI libname and include paths for FreeBSD
Summary: As noted in a discussion about testing the LLVM 6.0.0 release candidates (with libc++) for FreeBSD, many tests turned out to fail with "exception_ptr not yet implemented". This was because libc++ did not choose the correct C++ ABI library, and therefore it fell back to the `exception_fallback.ipp` header. Since FreeBSD 10.x, we have been using libcxxrt as our C++ ABI library, and its headers have always been installed in /usr/include/c++/v1, together with the (system) libc++ headers. (Older versions of FreeBSD used GNU libsupc++ by default, but these are now unsupported.) Therefore, if we are building libc++ for FreeBSD, set: * `LIBCXX_CXX_ABI_LIBNAME` to "libcxxrt" * `LIBCXX_CXX_ABI_INCLUDE_PATHS` to "/usr/include/c++/v1" by default.
