Add a SUBDIR_PARALLEL option to bsd.subdir.mk, to allow make to process all the SUBDIR entries in parallel, instead of serially. Apply this option to a selected number of Makefiles, which can greatly speed up the build on multi-core machines, when using make -j. This can be extended to more Makefiles later on, whenever they are verified to work correctly with parallel building. I tested this on a 24-core machine, with make -j48 buildworld (N = 6): before stddev after stddev ======= ====== ======= ====== real time 1741.1 16.5 959.8 2.7 user time 12468.7 16.4 14393.0 16.8 sys time 1825.0 54.8 2110.6 22.8 (user+sys)/real 8.2 17.1 E.g. the build was approximately 45% faster in real time. On machines with less cores, or with lower -j settings, the speedup will not be as impressive. But at least you can now almost max out a machine with buildworld! Submitted by: jilles MFC r263833: Enable parallel building for gnu/usr.bin and usr.bin/clang too.

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

Add a new knob WITH_DEBUG_FILES to control the building of standalone debug files for userland programs and libraries. The "-g" debug flag is automatically applied when WITH_DEBUG_FILES is set. The debug files are named ${prog}.debug and ${shlib}.debug for consistency with other systems and documentation. In addition they are installed under /usr/lib/debug, to simplify the process of installing them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the base system place the standalone debug files in a .debug subdirectory. GDB automatically searches both of these directories for standalone debug files.
