7621eebbb1 Omit from the universe build all config files tagged with
#NO_UNIVERSE. Many of these config files are important examples, but
add little to no regresive value to the intended purpose of
UNIVERSE. We now build over 120 kernels during universe. There's
really little to no value to this over building say 60 or even 30 of
them (either is still a way too big number). This is especially true
for kernels that are nothing more than including a common base and
adding a static DTB file. Start by pruning 1/3 of the arm kernels that
add little regresion value.

73279d4113 Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental.
This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.

armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
 * WITH_ARM_EABI
 * WITHOUT_GCC
 * WITHOUT_GNUCXX

In addition, without an external toolchain, the following need to be left
as their default:
 * WITH_CLANG
 * WITH_CLANG_IS_CC

As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.

a3058216b5 Ensure make -j N universe works correctly, by checking for an up-to-date
make before starting the universe targets themselves.  Otherwise, all of
the targets would attempt to build make simultaneously, overwriting each
other's copies of the make object files and executable.  This could lead
to strange errors, for example when partially-written make executables
are invoked.

Also amend r216620, to make the rest of universe wait properly until the
upgrade_checks target is finished, by adding universe_${target}_prologue
to the .ORDER target.  Otherwise, make will be too smart for its own
good, and start building the universe targets simultaneously with the
prologues anyway.

10098a6ec2 When building universe ensure the required worlds are finished before
starting the kernels. Before this the kernels would be built as part of the
last architecture universe target. There can cause problems when this world
finishes before the other worlds as the host compiler may be picked up
rather than the target compiler.

The solution is to add a target to build the universe kernels that depends
on all the world targets finishing. As we may not be building a world only
depend on it when MAKE_JUST_KERNELS is undefined.

0815243c39 Add support for bmake. This includes:
1.  Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
    there's a bootstrap complication in ths respect. Avoid it. Make the
    necessary changes to have upgrade_checks work wth bmake anyway.
2.  Remove the use of -E. It's not needed in our build because we use ?= for
    the respective variables, which means that we'll take the environment
    value (if any) anyway.
3.  Properly declare phony targets as phony as bmake is a lot smarter (and
    thus agressive) about build avoidance.
4.  Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
    smarter about build avoidance and should not find files we generate in
    the source tree. We should not have files in the repository we want to
    generate, but this is an easier way to cross this hurdle.
5.  Have behavior under bmake the same as it is under make with respect to
    halting when sub-commands fail. Add "set -e" to compound commands so
    that bmake is informed when sub-commands fail.
6.  Make sure crunchgen uses the same make as the rest of the build. This
    is important when the make utility isn't called make (but bmake for
    example).
7.  While here, add support for using MAKEOBJDIR to set the object tree
    location. It's the second alternative bmake looks for when determining
    the actual object directory (= .OBJDIR).

4da573d910 Merging of projects/armv6, part 3
r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions.  In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
 * GCC to default to arm1176jz-s
 * GCC to predefine __FreeBSD_ARCH_armv6__
 * gas to default to ARM_ARCH_V6K
 * uname -p to return 'armv6'
 * make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

69c488cdc6 It's a bit odd, but "make update" in src/ can also update the ports/,
doc/, and now www/ trees, but only using the "cvsup" transport.

When "make update" is run using a tree's makefile, it can also use
"cvs" (except for www/) and "svn" (only src/).

Clean up documentation and code regarding "make update":

- Increase oddness by adding support for WWWSUPFILE and NO_WWWUPDATE to
  Makefile.inc1 (analogous to PORTSSUPFILE/NO_PORTSUPDATE and
  DOCSUPFILE/NO_DOCUPDATE; WWWSUPFILE already supported by www/Makefile).

- Document all trees that support CVS_UPDATE.

- Document all trees that support SUP_UPDATE.

- Document SVN_UPDATE.

- Document NO_WWWUPDATE.

- make.conf(5) mistakenly said that *SUPFILE* had defaults.

- Add an example entry for WWWSUPFILE.

92f64fb9e4 When TARGET_ARCH_${kernel} gets set, it is using the host's config,
not the one we build as part of make world.  This means that make
universe will fail if building on a too-old current or any stable
system prior to a few days ago in weird ways (parse errors from
shell).  This copes with these old systems in two ways:

(1) Works around the WARNING: issue by filtering all warnings that
    sneak onto stdout.

(2) if TARGET_ARCH_${kernel} winds up being empty, then we error out
    immediately with a semi-useful error message.  This usually comes from
    config not groking -m.

Ideally, we'd use a buildworld's config here, but that's tricky, so
I'll leave that detail to others to fix (it has to be done post make
world for the arch rather than at the top level makefile).  This
should make 'make universe' usable from recent 8-stable systems
(recent == last few months or so) for building -current.  They have
-m, but spewed warnings out stdout.  Older systems will now at least
get a firm error early rather than a confusing error late.

Remove __gnu89_inline.

  Now that we use C99 almost everywhere, just use C99-style in the pmap
  code. Since the pmap code is the only consumer of __gnu89_inline, remove
  it from cdefs.h as well. Because the flag was only introduced 17 months
  ago, I don't expect any problems.

It was backed out, because it prevented us from building kernels using a
7.x compiler. Now that most people use 8.x, there is nothing that holds
us back. Even if people run 7.x, they should be able to build a kernel
if they run `make kernel-toolchain' or `make buildworld' first.

1bdb3fb97e Introduce a variable TARGETS that can be set on the make command line
and that controls which platforms are being built as part of a "make
universe". By default TARGETS is set to the 8 platforms currently
being built. This variable is useful for running or re-running a
"make universe" with only a selected set of platforms. This makes the
universe target slightly more useful in cases the universe is limited
to a developer's scope or objectives. For example, when a universe
failed for a particular platform and fixes need to be tested for that
particular platform then a developer can restart the universe for
only that platform, even if the initial universe is still building
other platforms.

e2a3608153 Add delete-old and delete-old-libs targets:
- removes obsolete files/dirs or libraries.
  - works in interactive (default) and batch mode
  - respects DISTDIR
  - documented in UPDATING and build(7)

The head of the file ObsoleteFiles.inc contains instructions how to add
obsolete files/dirs/libs to the list. Obviously one should add obsolete
files to this list, when he removes a file/dir/lib from the basesystem.

Additionally add check-old target:
  - allows re@ to check if a file on the obsolete list resurfaces

Design goals:
  - allows full control by the user (default interactive mode)
  - possibility of scripted removal of obsolete files (batch mode)
  - opt-in removal of files (explicit list of files)
  - seperate removal of libs (2 delete targets)

Important design decissions:
  - structured list of files to remove instead of a plain text file:
    * allows to remove additional files if a NO_foo knob is specified
      without the need to change the targets (no NO_foo knob is respected
      yet)
  - not using mtree like NetBSD does:
    * mtree doesn't has an interactive mode

e9bddef1f0 Previous revision didn't fix all cases. For example,
testing for variables that are always defined (e.g.,
"make -V CC") would still print a false warning.  Fix
this by only passing a submake the MAKEOBJDIRPREFIX=*
argument if it was present.  As a result, we loose
the check for -DMAKEOBJDIRPREFIX, or an esoteric
"MAKEOBJDIRPREFIX = foo" (with embedded spaces), but
these are unorthodox enough to not care about them.

The make(1) bug mentioned in the previous revision
was just fixed in make/main.c,v 1.109.
2004-12-16 19:55:57 +00:00
Marcel Moolenaar
26e8ef3fe8 Unbreak the MAKEOBJDIRPREFIX variable check by avoiding bugs in make(1).
When make flags are passed to make in the environment, the string is
chopped up in an (argc,argv) vector. This happens in brk_string() and
the chopped up string is stored in static buffer. When this includes
something like "-V BINMAKE", then a pointer into the static buffer is
put on the variables list for evaluation later. However, brk_string()
is used for more than just chopping up the MAKEFLAGS env. variable, so
it's very likely that the static buffer is clobbered. In fact, this is
exactly what happens.
The result is that _MAKEOBJDIRPREFIX gets assigned whatever garbage
the child make happens to emit, causing the test to fail. Like this:

pluto2% cd /usr/src
pluto2% make -V BINMAKE
"/q/6.x/src/Makefile", line 94: MAKEOBJDIRPREFIX can only be set in environment, not as a global (in /etc/make.conf) or command-line variable.
pluto2% make -dv -V BINMAKE | & grep _MAKEOBJDIRPREFIX
Global:_MAKEOBJDIRPREFIX = }

The fix is to not use MAKEFLAGS for this, but simple pass the flags
as arguments. Ideally make(1) should be fixed but that's beyond the
scope of my attention span.

This fixes release.

829340b175 Retired the "most" and "installmost" targets -- they just
do not have a chance to work nowadays as we have a lot of
internal libraries in lib/.

d911f786ab Limit testing for an up-to-date version of make(1) to the world and
buildworld targets by default, but allow it to be done for all user
targets by introducing a boolean option, named ALWAYS_CHECK_MAKE.

This change is by no means perfect and I don't even want to claim
this to be a solution. It does however address the fact that not
everybody likes to see make(1) rebuilt simply because the regression
test failed for some reason or other, including pilot error. It
therefore serves the purpose of keeping the crowd happy until we
have something better or simply reached a compromise.

The reasons for changing the default behaviour are:
o  It avoids a negative, possibly non-intuitive option,
o  It's according to POLA and fond of feet,
o  Only buildworld is documented to do its best to be
   successful at reasonably cost.

5ab778118b - Don't print "elf" before printing "make world" (aout support has been
removed).

- Avoid using printf(1) where a simple shell's built-in echo is enough.

ef2c779bf9 Use an up-to-date make binary in the upgrade_checks target if
one is already available.  This avoids sometimes unnecessary
step of attempting to rebuild the make binary again which may
fail at all if, for example, one has removed his /usr/include
before doing an installworld (to keep /usr/include tidied up).

ead4296edb Don't hardcore PATH into BINMAKE; the latter should only be
comprised of the path to a make(1) binary (possibly the one
built by the "make" target in this Makefile), and a path to
a fresh share/mk.  The idea is to allow "make release" pick
up the right "make" binary, if one exists.

This fixes release.5 I broke with the last commit here; the
second PATH here was overriding the right one from WMAKEENV
while rebuilding the "build-tools" for crunched binaries.

Fixed nearby bug: propagate the root Makefile's idea of
the appropriate "make" binary down to release/Makefile.
