Convert gnu to using SRCTOP

2017-03-12T18:59:16Z

Prefer SRCTOP over CURDIR/../../contrib, etc. However, retain the "up one level" instances of ../ because they are really relative to this part of the tree and not a means to find the root of the tree. As such, it's better to leave them since that further the goal of being able to move directories if watned to in the future.

Follow-up r297842: Rework header generation to fix always rebuilding.

2016-04-18T18:13:58Z

This reworks the handling of common headers to just include the needed logic rather than invoke MAKE. This avoids the problem listed in r297842 and avoids other dependency tracking issues. Pointyhat to: bdrewery Reported by: Nikolai Lifanov Sponsored by: EMC / Isilon Storage Division

META_MODE: Avoid changed build command every build.

2016-04-12T02:45:19Z

Because the file is generated with -f using another Makefile, 2 different Makefiles are trying to handle the .meta file for the target. The obvious .NOMETA_CMP or .NOMETA on the ${MAKE} targets don't work as they are very limited in scope in bmake. Using .PHONY fixes the problem and ensures that the ${MAKE} command is always ran to check if it is outdated in the sub-make. An example of the problem in gnu/lib/libgcc (with make -dM): /usr/obj/root/git/freebsd/gnu/lib/libgcc/tm.h.meta: 2: a build command has changed TARGET_CPU_DEFAULT="" HEADERS="options.h i386/biarch64.h i386/i386.h i386/unix.h i386/att.h dbxelf.h elfos-undef.h elfos.h freebsd-native.h freebsd-spec.h freebsd.h i386/x86-64.h i386/freebsd.h i386/freebsd64.h defaults.h" DEFINES="" /bin/sh /root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc/mkconfig.sh tm.h vs (cd /root/git/freebsd/gnu/lib/libgcc; make -f /root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile MFILE=/root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile GCCDIR=/root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc tm.h) Skipping meta for tm.h: .NOMETA (cd /root/git/freebsd/gnu/lib/libgcc; make -f /root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile MFILE=/root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile GCCDIR=/root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc tm.h) `tm.h' is up to date.

Remove the old depend (mkdep) code and make FAST_DEPEND the one true way.

DIRDEPS_BUILD: Regenerate without local dependencies.

These are no longer needed after the recent 'beforebuild: depend' changes and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports skipping 'make depend'. Sponsored by: EMC / Isilon Storage Division

Fix installation of 32bit libraries after r288074.

2015-09-21T21:44:02Z

FILES is not used when LIBRARIES_ONLY is set, which is used to build and install the lib32 sysroot. All of the csu files do quality as "libraries" for this case so just undefine LIBRARIES_ONLY. This is still better than the previous realinstall handling as it does not hook into META_MODE properly. Sponsored by: EMC / Isilon Storage Division

Replace realinstall: and META_MODE staging hacks with FILES mechanism.

2015-09-21T18:39:13Z

This partially reverts r270170 for lib/csu/i386 while retaining the change for using bsd.lib.mk. These FILES groups could go into lib/csu/Makefile.inc but I've kept them in the Makefiles for clarity. Sponsored by: EMC / Isilon Storage Division

Add META_MODE support.

2015-06-13T19:20:56Z

Off by default, build behaves normally. WITH_META_MODE we get auto objdir creation, the ability to start build from anywhere in the tree. Still need to add real targets under targets/ to build packages. Differential Revision: D2796 Reviewed by: brooks imp
