* When building a kernel with the -k option, make obj in $TOP/etc to
ensure that the correct KERNOBJDIR is created and used. Previously,
KERNOBJDIR could sometimes be an objdir outside the source tree
and sometimes $TOP/sys/arch/$ARCH/compile inside the source tree,
depending on whether or not a complete build had beed done before
the kernel build.
* Renamed KERNCONFNAME to kernconfname, for consistency with what
seems to be a convention that variables local to build.sh (as
opposed to make or environment variables) have lowercase names.
* Renamed the do_buildonlytools and do_buildonlykernel variables to
do_buildtools and do_buildkernel, because the word "only" is no
longer appropriate now that more than one of them can be active
simultaneously.
* Changed a few '|| exit 1' tests to '|| bomb "message"', and added a
few more similar tests.
* Changed all 'echo "===> ..."' to use $runcmd, and added a few more
similar echos. Previously, some used $runcmd and some did not.
kernel using the $TOOLDIR toolchain. If kern doesn't contain `/', it will
be searched for in ${KERNCONFDIR} (typically, sys/arch/${MACHINE}/conf).
- Improve ./build.sh usage.
- Add some examples to the documentation.
This is heavily based on [toolchain/18739] from Alan Barrett <apb@cequrux.com>,
with improvements by me.
Obsolete NBUILDJOBS; build.sh just passes -jN through to make(1),
which inherits it cooperatively through the build tree. Fix
documentation so that it's shown to be deprecated.
If you use build -jN, please save full build logs so that errors due
to missing dependancies can be analyzed and corrected.
* Rewrite src/tools Make logic to work like the rest of the tree wrt
"dependall" and "install". The old "make build" hack is gone.
* Remove the MKTOOLS logic. This was linked to the "make build" hack,
and was only needed because TOOLDIR originally had no writable default.
* Redo the GNU configure/make logic to make it fit reasonably in a
BSD make wrapper. Use new ${.ALLTARGETS} variable to scan for
targets in $(srcdir), and mark them with .MADE: to prevent rebuilding.
* Only build cross tools in src/tools; remove some messy logic in
src/usr.* and src/gnu/usr.* that would do target filename rewriting
(improves consistency and readability).
* Add the ability to build cross gdb at tool build time by setting
MKCROSSGDB (default no) to "yes" in mk.conf.
* Add src/tools/groff and set up paths to work with this cross groff.
