Fix this build for clang. MFC r259730: To avoid having to explicitly test COMPILER_TYPE for setting clang-specific or gcc-specific flags, introduce the following new variables for use in Makefiles: CFLAGS.clang CFLAGS.gcc CXXFLAGS.clang CXXFLAGS.gcc In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for the right compiler. MFC r259913: For libstand and sys/boot, split off gcc-only flags into CFLAGS.gcc. MFC r259927: Fix pc98 build, by also forcing COMPILER_TYPE in sys/boot/pc98/boot2's Makefile. Pointy hat to: dim

libstdc++: Revert the expl addition from r246857.

When the needed configuration update to libstdc++ was done. we overlooked that expl hasn't been merged. This is causing breakage in some ports. Reported by: Diane Bruce Reviewed by: dim

MFC r246028 (by theraven):

2013-02-05T19:10:50Z

Fix some symbol version mismatches between libstdc++ and libsupc++/libcxxrt that were causing the runtime and STL libraries to see different versions of various classes and functions when libstdc++ is used as a filter. Note: This changes the ABI for libcxxrt, but libcxxrt is currently only in -STABLE for testing and is not used by anything unless explicitly enabled by the end user. No default compiler configurations use it. libc++ will need to be recompiled after this change. make buildworld will do this automatically, but make in lib/libc++ will not necessarily work unless the new libcxxrt is installed first. PR: kern/171610, stand/175453 Reviewed by: kib MFC r246297: Add several missing symbols to libcxxrt's symbol version map, and remove a few duplicates. This should fix building world with -stdlib=libc++ after r246028. Submitted by: Yamaya Takashi

Fix several clang warnings in libstdc++, which were exposed by the recent atf import. These changes are purely cosmetic, no functional change. MFC r241959: Fix a number of other clang warnings in libstdc++, which could appear when building other C++ software with it. Also fix one actual bug in libsupc++, which was exposed by such a warning. This latter fix is the only functional change. MFC r241960: For building GNU libstdc++ and libsupc++, filter out libc++-specific and -std= flags above c++98 or gnu++98 from CXXFLAGS *after* including bsd.lib.mk, otherwise some additions to CXXFLAGS done in bsd.*.mk might not be preserved.

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
