Import libc++ 3.4 release. This contains a lot of bugfixes, and some preliminary support for C++1y. MFC r261604: HEAD is not buildable for the past day. Commit a 'quick fix' in order to permit buildworld to complete. Reviewed by: theraven MFC r261608: Apply a cleaner solution for the sign warnings that can occur when compiling libc++'s header with -Wsystem-headers on. This has also been submitted upstream. Reported by: asomers MFC r261801: An ABI incompatibility crept into the libc++ 3.4 import in r261283. It was caused by upstream libc++ commit r194536, which aimed to make the headers more standards-compliant, by making std::pair's copy constructor trivial. Unfortunately, this could cause certain C++ applications using shared libraries built against the previous version of libc++ to crash. Fix the ABI incompatibility by making std::pair's copy constructor non-trivial again. Please note: Any C++ applications or shared libraries built with libc++ between r261283 and this revision should be recompiled. Reported by: stefanf

After r253839, which modifies ld's behaviour to not automatically pull in needed libraries, change libc++.so into a linker script, so it can automatically pull in libcxxrt.so. [Note to stable/9 users: the above statement about ld's behaviour is not (yet) applicable to the version of ld in 9.x, but this change will help when building C++ programs with libc++, in combination with the ports version of ld.]

Fix broken macro checking in the libc++ Makefile, introduced in r241909. This caused -std=c++0x not to be passed to the build by default. Pointy hat to: dim

MFC r241909:

2012-10-29T21:11:37Z

Allow building libc++ with any custom -std=xxx flag. Note that using -std=gnu++98 will give a lot of warnings with clang, so please use -std=c++0x or higher, or use NO_WERROR.

MFC r239680:

2012-09-08T11:34:22Z

Add libcxxrt's objects (prefixing them with cxxrt_ to avoid collisions) to libc++.a and libc++_p.a, to make static linking of C++ executables with libc++ easier. This is similar to the approach used in libstdc++. MFC r239686: When using -stdlib=libc++, add the correct dependency to .depend in bsd.prog.mk. Submitted by: Yamaya Takashi MFC r239695: For building libstdc++ and libsupc++, filter out any -stdlib=libc++ option from CXXFLAGS, otherwise these libraries will not build. Similarly, filter out any -std=xxx options that aren't supported. Submitted by: Yamaya Takashi

MFC r236444:

2012-06-05T06:43:45Z

Install libcxxrt's C++ ABI and unwind headers. This is done in libc++'s Makefile, so these headers go into the same destination directory as libc++'s own headers, currently /usr/include/c++/v1.

Tabify libcxxrt and libc++'s Makefiles.
