Author: dim Date: Sun Mar 27 21:20:43 2016 New Revision: 297322 URL: https://svnweb.freebsd.org/changeset/base/297322 Log: Pull in r255683 from upstream libc++ trunk (by Eric Fiselier): [libcxx] Enable noexcept for GCC 4.6 and greater Summary: This patch allows GCC 4.6 and above to use `noexcept` as opposed to `throw()`. Is it an ABI safe change to suddenly switch on `noexcept`? I imagine it must be because it's disabled in w/ clang in C++03 but not C++11. Reviewers: danalbert, jroelofs, mclow.lists Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D15516 This should fix errors from gcc 4.6 and higher when compiling llvm-cov and/or other llvm tools.
