Copy bsd.own.mk to bsd.opts.mk and separate out the option setting code from the rest. Include bsd.opts.mk in bsd.own.mk to preserve current behavior. Future revisions will replace the inclusion of bsd.own.mk elsewhere with bsd.opts.mk or a more appropriate new file that's still being finalized.

# Option file for src builds.
#
# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
# with sensible (usually) defaults.
#
# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
# are applicable for that Makefile (typically there are none, but sometimes there
# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
# to omit from that make.

# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them

Better documentation for why KERBEROS and OPENSSH are here, and where to look for all the other options that used to be here (well, in bsd.own.mk) Suggested by: des@

# Only these options are used by bsd.*.mk. KERBEROS and OPENSSH are
# unforutnately needed to support statically linking the entire
# tree. su(1) wouldn't link since it depends on PAM which depends on
# ssh libraries when building with OPENSSH, and likewise for KERBEROS.
# All other variables used to build /usr/src live in src.opts.mk
# and variables from both files are documented in src.conf(5).
Split up the options into those used only by bsd.mk.* or sys.mk and the rest. Add note of caution for the surprises that popped up. MK_SSP is the only one used by sys.mk, and it likely needs even extra attention.

Add built-in ccache build support via WITH_CCACHE_BUILD option. ccache is mostly beneficial for frequent builds where -DNO_CLEAN is not used to achieve a safe pseudo-incremental build. This is explained in more detail upstream [1] [2]. It incurs about a 20%-28% hit to populate the cache, but with a full cache saves 30-50% in build times. When combined with the WITH_FAST_DEPEND feature it saves up to 65% since ccache does cache the resulting dependency file, which it does not do when using mkdep(1)/'CC -E'. Stats are provided at the end of this message. This removes the need to modify /etc/make.conf with the CC:= and CXX:= lines which conflicted with external compiler support [3] (causing the bootstrap compiler to not be built which lead to obscure failures [4]), incorrectly invoked ccache in various stages, required CCACHE_CPP2 to avoid Clang errors with parenthesis, and did not work with META_MODE. The option name was picked to match the existing option in ports. This feature is available for both in-src and out-of-src builds that use /usr/share/mk. Linking, assembly compiles, and pre-processing avoid using ccache since it is only overhead. ccache does nothing special in these modes, although there is no harm in calling it for them. CCACHE_COMPILERCHECK is set to 'content' when using the in-tree bootstrap compiler to hash the content of the compiler binary to determine if it should be a cache miss. For external compilers the 'mtime' option is used as it is more efficient and likely to be correct. Future work may optimize the 'content' check using the same checks as whether a bootstrap compiler is needed to be built. The CCACHE_CPP2 pessimization is currently default in our devel/ccache port due to Clang requiring it. Clang's -Wparentheses-equality, -Wtautological-compare, and -Wself-assign warnings do not mix well with compiling already-pre-processed code that may have expanded macros that trigger the warnings. GCC has so far not had this issue so it is allowed to disable the CCACHE_CPP2 default in our port. Sharing a cache between multiple checkouts, or systems, is explained in the ccache manual. Sharing a cache over NFS would likely not be worth it, but syncing cache directories between systems may be useful for an organization. There is also a memcached backend available [5]. Due to using an object directory outside of the source directory though you will need to ensure that both are in the same prefix and all users use the same layout. A possible working layout is as follows: Source: /some/prefix/src1 Source: /some/prefix/src2 Source: /some/prefix/src3 Objdir: /some/prefix/obj Environment: CCACHE_BASEDIR='${SRCTOP:H}' MAKEOBJDIRPREFIX='${SRCTOP:H}/obj' This will use src*/../obj as the MAKEOBJDIRPREFIX and tells ccache to replace all absolute paths to be relative. Using something like this is required due to -I and -o flags containing both SRC and OBJDIR absolute paths that ccache adds into its hash for the object without CCACHE_BASEDIR. distcc can be hooked into by setting CCACHE_PREFIX=/usr/local/bin/distcc. I have not personally tested this and assume it will not mix well with using the bootstrap compiler. The cache from buildworld can be reused in a subdir by first running 'make buildenv' (from r290424). Note that the cache is currently different depending on whether -j is used or not due to ccache enabling -fdiagnostics-color automatically if stderr is a TTY, which bmake only does if not using -j. The system I used for testing was: WITNESS Build options: -j20 WITH_LLDB=yes WITH_DEBUG_FILES=yes WITH_CCACHE_BUILD=yes DISK: ZFS 3-way mirror with very slow disks using SSD l2arc/log. The arc was fully populated with src tree files and ccache objects.

Hook the meta/nofilemon build into using FAST_DEPEND. FAST_DEPEND is intended to be the "skip 'make depend' and mkdep" feature. Since DIRDEPS_BUILD does this already with some of its own hacks, and filemon doesn't need this, and nofilemon does, teach it how to handle each of these cases. In meta+filemon mode filemon will handle dependencies itself via the meta mode logic in bmake. We still want to set MK_FAST_DEPEND=yes to enable some logic that indicates that 'make depend' is skipped in the traditional sense. The actual .depend.* files will be skipped. When nofilemon is set though we still need to track and generate dependencies. Sponsored by: EMC / Isilon Storage Division
