Separate devicetree .dts -> .dtb building from kernel builds. They are now

<bsd.x11.mk>: infrastructure to support reach-over builds of xsrc

If EXTERNAL_TOOLCHAIN is defined, allow the compiler to define the
location of crt{begin,end}{,S}.o and libgcc.a. Encapsulate all of
this logic into the new bsd.gcc.mk, and use it in bsd.prog.mk and
bsd.lib.mk.

Add bsd.rpc.mk to FILES

Only use the MKDYNAMICROOT semantics (i.e. -rpath=/lib,/usr/lib and
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.

The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.

This is done by decoupling where a shlib is installed from how it
is located. Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only. SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.

The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.

a "make depend" on all the directories and then a "make all".

Initial revision

Add logic for /usr/lib/private libraries.

New variables for makefiles to define:

<bsd.lib.mk> LIBSUBDIR -- If nonempty, install library into
${LIBDIR}/${LIBSUBDIR} instead of ${LIBDIR}. Typically set
either to empty or to `private'.

<bsd.lib.mk> LIBDPSUBDIRS -- List of subdirectories _subdir_ to add
-L${SHLIBDIR}/${_subdir_} -Wl,-R${SHLIBDIR}/${_subdir_} to
ldflags when linking library. Note: Should only be used inside
private libraries, not inside public libraries to link against
private libraries, which can't work -- see comment.

<bsd.prog.mk> PROGDPSUBDIRS -- List of subdirectories _subdir_ to add
-L${SHLIBDIR}/${_subdir_} -Wl,-R${SHLIBDIR}/${_subdir_} to
ldflags when linking program.

(XXX bsd.lib.mk/bsd.prog.mk should figure LIBDPSUBDIRS/PROGDPSUBDIRS
out automatically by LIBDPLIBS/PROGDPLIBS, but for now we don't have
that mechanism -- TBD in subsequent work.)

Libraries that we want to install because we use them in binaries we
ship, but that we want to keep private from applications so we don't
have to worry about ABI breakage or leakage into pkgsrc builds,
should generally set:

LIBSUBDIR= private # Install into /usr/lib/private.
NOCOMPAT= # defined # Don't build compat lib.
NOLINKLIB= # defined # Don't install .so link or .a lib.

(XXX Maybe we should have a `LIBISPRIVATE= installed' or something
for this combination of options, but for now I'm putting in the
minimal mechanism to implement this and we can condense a common
pattern later.)

Programs using the library will also have to set

PROGDPSUBDIRS+= private

so that they will get the rpath /usr/lib/private.

going to add __always_inline to the functions called from _mcount()
discussed on http://mail-index.netbsd.org/source-changes-d/2021/10/25/msg013480.html

In some arch, _mcount() would be called recursively when built with COPTS=-O0.

Normally, functions called from mcount.c are expected to be expanded inline,
so _mcount() will never be called recursively. But when build with COPTS=-O0,
`static inline' functions aren't inlined, and _mcount() will be called
recursively.

Even if _mcount() has `__attribute__((__no_ instrument_function__))',
it has no effect on the calling external (no-inlined) function.

To avoid this, PROF.<fn> is added can be set the profiling flag of any file.
"PROF.mcount.c" is set to blank by default, mcount.c itself is compiled
without -pg.

Remove MKCRYPTO option.

Originally, MKCRYPTO was introduced because the United States
classified cryptography as a munition and restricted its export. The
export controls were substantially relaxed fifteen years ago, and are
essentially irrelevant for software with published source code.

In the intervening time, nobody bothered to remove the option after
its motivation -- the US export restriction -- was eliminated. I'm
not aware of any other operating system that has a similar option; I
expect it is mainly out of apathy for churn that we still have it.
Today, cryptography is an essential part of modern computing -- you
can't use the internet responsibly without cryptography.

The position of the TNF board of directors is that TNF makes no
representation that MKCRYPTO=no satisfies any country's cryptography
regulations.

My personal position is that the availability of cryptography is a
basic human right; that any local laws restricting it to a privileged
few are fundamentally immoral; and that it is wrong for developers to
spend effort crippling cryptography to work around such laws.

https://mail-index.netbsd.org/tech-userlevel/2017/05/06/msg010547.html

P.S. Reviewing all the uses of MKCRYPTO in src revealed a lot of
*bad* crypto that was conditional on it, e.g. DES in telnet... That
should probably be removed too, but on the grounds that it is bad,
not on the grounds that it is (nominally) crypto.

According to the USPTO Patent Term Calculator web site at
<https://www.uspto.gov/patent/laws-and-regulations/patent-term-calculator#heading-5>

Introduce MKSTRIPSYM build option

If it's yes, all local symbols of shared libraries are stripped
(default). If it's no, only temporary local symbols are stripped;
for example, symbols of static functions are kept. Keeping such

getting a backtrace from a rump server loading modules (shared
libraries).

libpthread_dbg(3) deletion from the base distribution

libpthread_dbg(3) is a remnant library from the M:N thread model

of debuggers.

Currently in the 1:1 model it's not used in GDB neither in LLDB and it's
not either planned to be used. It's current function to read pthread_t
structures is realizable within a regular debugger capable to
instrospect objects within a tracee (GDB, LLDB...).

the default symlink to .7, that would be nice. renaming it so that
it's easier to choose via xorg.conf is a little more tricky..)

Add a new build make variable, CONFIGOPTS, which is passed to config(1)
when building kernels. Revert "mkernel=*" and "mkernels" in favor of
this option.

Diff posted on source-changes-d@, approved by (null).

Add WARNS=6

branches: 1.335.2;
Provide and document GZIP_N_FLAG and TOOL_GZIP_N.
These may be used to pass "-nT" instead of just "-n"
when the gzip program is actually pigz.

Add MKGROFFHTMLDOC and make it default to no. It seems that sometimes
when generating html groff runs netpbm behind your back. Needless to
say we don't have netpbm in base, so this fails on a clean install; so
for now disable generating html for /usr/share/doc by default.
Workaround for PR 48970.

It seems that all available document preparation toolchains are made
of fail.

Remove HTMLDOCDIR; it is no longer used (and doesn't fit the docs
scheme) and it was never honored anyway except in a couple places.

Use TOOL_NCDCS to turn an ibmnws kernel automatically into a valid NCD
firmware image for netbooting. This is still a valid ELF kernel, but with
a patched CRC checksum and image size included.

As discussed on tech-toolchain, offer a new make variable MKKDEBUG - if
set to "yes", kernel builds will gain debug info and a netbsd.gdb will
be created (same as adding "makeoptions DEBUG=-g" to the config file).

Add -g (gnu) so lint recognizes __attribute__

branches: 1.329.2;
Add MKCTF

This variable separates CTF stuffs from MKDTRACE; we can build DTrace
solely without building and using them. This allows us to use DTrace
even if CTF stuffs have problems (actually they have now).

This variable would be merged into MKDTRACE eventually, once CTF stuffs
work correctly again.

Rename NetBSD/hp700 to NetBSD/hppa.

Unfortunately our VCS isn't very helpful here.

Document TOOL_GZIP.

- Add a new bsd.host.mk that contains all the HOST_ variables extracted from
bsd.sys.mk and bsd.own.mk
- Add protection requiring that:
1. bsd.sys.mk is not include from other Makefiles directly
2. bsd.own.mk must be included before bsd.sys.mk since it
sets variables that bsd.sys.mk uses as conditionals.

This is step 1 of removing all variable settings from bsd.sys.mk and
leaving behind only rules. This way, the structure of a standard Makefile
is:
variable overrides

optionally include bsd.own.mk
optionally include bsd.endian.mk

variable settings that use variables defined in bsd.own.mk

include a one or more rule .mk files (such as bsd.prog.mk etc)

use bsd.syscall.mk

Document new default for MKARZERO.

Describe MACHINES.${MACHINE_CPU}. <fixme>
Add sparc64 to MACHINES.sparc since sparc64 can be build as sparc.

Relink binaries if crti.o changes.

add MKDEPCXX, that is used for C++ files depend creation. also
add some missing ${COPTS.${.IMPSRC:T}} and ${CPUFLAGS.${.IMPSRC:T}}
to the dependancy rules.

this makes it possible to have C++ files .d files created with the
C++ compiler, and with the normal options for this file, which
means that we can build libstdc++-v3 from gcc 4.8.

Add libxcb

Fixed a typo

New variable MKX11MOTIF to enable building libGLw with Motif support.
Defaults to 'no'.

add LIBX11_XCB; unfortunately since the library is named with a -
in it, we have to use an ugly hard coded assignment for now.
(could be cleaned up with more make variable magic i'm sure.)

MKLIBCXX and MKLIBSTDCXX

add new libevent2 libraries.

MKDEPINCLUDES support.

Hook Lutok into the build. This is all protected by the MKKYUA guard.

Add the MKKYUA knob.

MKKYUA defaults to no and will remain as such until the import is complete
and validated.

This knob does not currently have any effects on the build as nothing relies
on it yet. Upcoming imports and changes in this area will all be guarded by
this flag.

add TOOL_MKNOD

Document MAKEDIRTARGETENV

Document MKSLJIT variable.

On second thoughts, don't run "rm -rf" in bsd.clean.mk. Instead,
document that CLEANFILES and CLEANDIRFILES must not contain
directory names.

Make it easier build binaries against the host's libs, e.g.
libpthread which might be in /lib/x86_64-linux-gnu/libpthread.so.0
or some other unholy place.

add MKTPM, default to no

Add _NETBSD_VERSION_DEPENDS in bsd.own.mk. Targets that need
to be re-generated when the NetBSD version numberchanges,
or when any build-related variables change, may depend on
${_NETBSD_VERSION_DEPENDS}.

Document the MKKMOD build knob.

Note that the MKCOMPAT build knob is supported on mips64-based

add new option to build/use tools/pigz for compressing sets. for now
USE_PIGZGZIP defaults to "no". (it depends upon local <pthread.h> and -lz.)

you can set it to "yes" on most modern platforms just fine.

Always define TOOL_* variables in bsd.own.mk, not in bsd.sys.mk.

Previously, they were defined in bsd.own.mk if USETOOLS=yes, but in

SYMLINKS to install symlinked header files. INCSYMLINKS are installed with
'make includes'. This avoids using SYMLINKS and hacks with the 'linkinstall'
target in <bsd.links.mk>, as linksinstall occurs in 'make install' and hacks
to get it to occur in 'make includes' weren't robust, as seen in lib/libdes.

Yet more improvements to bsd.README.

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS

Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

Update documentation for some other make variables

bsd.dep.mk: add a dependency for *.d on ${SRCS} ${DPSRCS}. this should fix
some build problems where DPSRCS contains .h files that need to exist to
build the .d file.

document that bsd.dep.mk should be included after anything that might
update SRCS or DPSRCS so that the above works correctly, and actually
ensure this is the case.

add bsd.dep.mk

replace MKCXXSUPCXX(!=no) with USE_LIBSTDCXX(==no)

Change defined(CXX_SUPCXX) to MKCXXSUPCXX != "no".

Clarify that command-line overrides of the MKxxx variables should be
done via the environment rather than make(1) command-line variable
assignment, since the latter doesn't actually work as intended.

add a new bsd.own.mk variable: CXX_SUPCXX. from bsd.README:
+ CXX_SUPCXX If defined, the support libraries needed for this C++ program

stop installing install libtelnet. build under lib/libtelnet and reference
it from usr.bin/telnet and libexec/telnetd.
(reason for separate build: compiler flags)

Rename a large chunk of the make(1) variables which refer to a
program/tool from "FOO" to "TOOL_FOO". The new variables are:
TOOL_ASN1_COMPILE TOOL_CAP_MKDB TOOL_CAT TOOL_CKSUM TOOL_COMPILE_ET
TOOL_CONFIG TOOL_CRUNCHGEN TOOL_CTAGS TOOL_DB TOOL_EQN TOOL_FGEN
TOOL_GENCAT TOOL_GROFF TOOL_HEXDUMP TOOL_INDXBIB TOOL_INSTALLBOOT
TOOL_INSTALL_INFO TOOL_M4 TOOL_MAKEFS TOOL_MAKEINFO TOOL_MAKEWHATIS
TOOL_MDSETIMAGE TOOL_MENUC TOOL_MKCSMAPPER TOOL_MKESDB
TOOL_MKLOCALE TOOL_MKMAGIC TOOL_MKTEMP TOOL_MSGC TOOL_MTREE
TOOL_PAX TOOL_PIC TOOL_PREPMKBOOTIMAGE TOOL_PWD_MKDB TOOL_REFER
TOOL_ROFF_ASCII TOOL_ROFF_DVI TOOL_ROFF_HTML TOOL_ROFF_PS
TOOL_ROFF_RAW TOOL_RPCGEN TOOL_SOELIM TOOL_SUNLABEL TOOL_TBL
TOOL_UUDECODE TOOL_VGRIND TOOL_ZIC

For each, provide default in <bsd.sys.mk> of the form:
TOOL_FOO?= foo
and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:
TOOL_FOO= ${TOOLDIR}/bin/${_TOOL_PREFIX}foo

Document all of these in bsd.README.

This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.

Citrus iconv support(3)

bsd.lib.mk.

Add a CPUFLAGS variable which can be set by the user's mk.conf or in

CPUFLAGS Additional flags to the compiler/assembler to select
CPU instruction set options, CPU tuning options, etc.

Since CPUFLAGS is not implicitly set by any part of the make infrastructure,
it is safe to set in mk.conf, unlike COPTS or DBG.

Provide the MKPICLIB value in bsd.own.mk, rather than bsd.lib.mk. It

Deprecate SYS_INCLUDE and the optional SYS_INCLUDE=symlinks functionality,
and only support the "copies" default.
Per discussion on tech-userlevel@.

Only use the MKDYNAMICROOT semantics (i.e. -rpath=/lib,/usr/lib and
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.

The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.

This is done by decoupling where a shlib is installed from how it
is located. Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only. SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.

The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.

MDC2 is a patented algorithm; don't ship it in default libcrypto.
MKCRYPTO_MDC2 will build a separate library, libcrypto_mdc2.

Enable MKDYNAMICROOT=yes by default.
This means that:
+ /bin and /sbin (and the few programs in /usr/* which were statically
linked) are now dynamically linked.
+ The shared libraries that are needed by the /bin and /sbin programs
are now installed into /lib (with compatability symlinks from
/usr/lib). These are:
c crypt edit ipsec kvm m m387 termcap termlib util z
+ The shared linker is now in /libexec/ld.elf_so, and
/usr/libexec/ld.elf_so is a symlink to the former.

If you want the prior behaviour of "some applications statically linked,
the rest dynamically linked", set MKDYNAMICROOT=no in your mk.conf(5).

If you have a philosophical objection to dynamic libraries, continue
to set LDSTATIC=-static in your mk.conf(5), and please don't waste any
more time in trying to convince us why dynamic libraries are 3v1l.

* Eliminate the USE_NEW_TOOLCHAIN variable. Instead, split it into
two variables:

TOOLCHAIN_MISSING -- set to "yes" on platforms for which there is
no working in-tree toolchain (hppa, ns32k, sh5, x86_64).

EXTERNAL_TOOLCHAIN -- if defined by the user, points to the root of
an external toolchain (e.g. /usr/local/gnu). This enables the cross-build
framework even for TOOLCHAIN_MISSING platforms.

If TOOLCHAIN_MISSING is set to "yes", MKGDB, MKBFD, and MKGCC are all
unconditionally set to "no", since the bits are not there to build.

If EXTERNAL_TOOLCHAIN is set, MKGCC is unconditionally set to "no",
since the external toolchain's compiler is not in-sync with the
in-tree compiler support components (e.g. libgcc).

* Set MACHINE_CPU much earlier in bsd.own.mk, so that more tests in
that file can use it.

Build a .gdbinit in the objdir when building a program. The .gdbinit
file sets the shared library prefix to ${DESTDIR}, and adds "sources"
directives for each file listed in the GDBINIT Makefile variable.

Explicitly note that if NOxxx and USE_SHLIBDIR are set by a Makefile,
it must be before <bsd.own.mk> is included.

Add LIBPMC.

* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
building of support for using the corresponding API

For PROG_CXX DESTDIR builds, pull in -lstdc++ and -lm regardless

Remove the "MKLINT=no if HAVE_GCC3" hack; a patch to support lint
comments has been submitted to the GCC maintainers, so if you're
using a GCC 3.x that doesn't support lint, set MKLINT=no in mk.conf.

If HAVE_GCC3 is set, force MKLINT to "no", since GCC 3.x's C pre-processor
does not yet support our lint(1).

Per a suggestion from matthew green, PROG_CXX takes the place of
PROG for C++ programs.

Document PROG_CXX and HAVE_GCC3.

Document MKBFD, MKGDB, MKGCC.

* Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".

- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.

- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so

2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so

3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

NLS is commonly expanded to Native Language Support, not National Language
Support.

bsd.dep.mk: fix "make tags"

Fix "make tags" to actually build a tags file:
- Use !commands() instead of !target(), so that the rule actually works
- Write to ${.OBJDIR}/tags for read-only source (don't know why ${.TARGET}
isn't sufficient).
- Only match *.[cly] from ${.ALLSRCS} - just excluding *.h causes failures
because of ${targ}: subdir-${targ} in bsd.subdir.mk.

Thanks to uwe@ for assistance.

Most of the mv operations are to move temporary files to their final place.
Some use -f, others don't. This can lead to spurious build failures when
the user performing the build changes. Centralize, and always use -f.

Don't remap mkdep, otherwise we add dependencies for /usr/include instead
of ${DESTDIR}/usr/include and things go south.

PR toolchain/9618: add ".d" to MKDEP_SUFFIXES so the depend files are rebuilt
if any of their dependencies (i.e. the files they refer to) are changed.
This allows changes to transitive included headers to be handled properly.

when calling mkdep, pass any -std=* flags for C and C++ source files
to ensure that any definitions this implies are set

branches: 1.80.2;
add ${MKTARGET_CREATE} for tags

create mkdep output with a temporary file so that failures in
complation during .d creation don't leave an empty (stale) .d
file around to break future builds.

(hmm, probably could use .PRECIOUS here.)

add MKDEPCXX, that is used for C++ files depend creation. also
add some missing ${COPTS.${.IMPSRC:T}} and ${CPUFLAGS.${.IMPSRC:T}}
to the dependancy rules.

this makes it possible to have C++ files .d files created with the
C++ compiler, and with the normal options for this file, which
means that we can build libstdc++-v3 from gcc 4.8.

Add a rule to rebuild dependency files that contain stale entries automatically.

MKDEPINCLUDES support.

Allow use of traditional CPP to be set on a per platform base in sys.mk.
Honour this for dependency processing in bsd.dep.mk. Switch i386 and
amd64 assembly to use ISO C90 preprocessor concat and drop the
-traditional-cpp on this platform.

PR/42658: Geoff Wing: Quote directory variables to deal with spaces in the
source pathname.

Use ${TOOL_SED} instead if plain sed in Makefiles.

remove AINC support; it is now unnecessary

Cosmetically tweak how .PHONY is used by (generally) providing it as a source,
instead of using it as a target with all the rules as its sources.

Replace
:M-[IDU]*
with
:C/-([IDU])[ ]*/-\1/Wg:M-[IDU]*
so that arguments with whitespace after them work correctly.
Resolves [toolchain/18248] from Andrew White at Motorola.

Be consisent in this syntax; previously we'd sometimes we'd just have :M-[ID]*
which would ignore -Ufoo ...

(This needs :C///W support in make(1) that Simon Gerraty added for me :)

Use -- to separate mkdep options from cc ones.
Avoids problems when the cc options start with -fpic.

Use modified mkdep(1) (not cat) to merge '*.d' into '.depend'.
Allows some of the postprocessing to be done there instead of a separate
sed script called from 'afterdepend'.

fix a typo in previous pointed out by lukem

allow -traditional-cpp to be overridden when making dependancies

Rework how MAKEVERBOSE operates:

* Don't bother prefixing commands with a line of ${_MKCMD}\
and instead rely upon "make -s". This is less intrusive on
all the Makefiles than the former. Idea from David Laight.

* Rename the variables use to print messages. The scheme now is:
_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
From discussion with Alistair Crooks.

Provide _MKMSG{BUILD,CREATE,COMPILE,FORMAT,INSTALL,LINK,LEX,YACC} to display
${_MKMSG} " ... {$.TARGET}" and use appropriately.

Provide _MKMSGLINK.m to provide "link" message by itself (without ${.TARGET})

Replace _MKSHCMD with _MKSHECHO

Implement MAKEVERBOSE to control how "verbose" the standard make(1) rules are.
Supported values:
0 Minimal output ("quiet")
1 Describe what is occurring
2 Describe what is occurring and echo the actual command ("verbose")
This is the default, and is equivalent to the previous behaviour.

order .SUFFIXES similar to other *.mk files

Handle empty __DPSRCS.d, avoiding executing commands like "cat > .depend"
in directories where only non-C/C++ files are in SRCS (e.g.: the forth
code for sparc bootblocks).

Patch from Luke.

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

tweak ${DEPENDSRCS.d} target so that ${SRCS} isn't there. this fixes the
"make: out of memory" problem when make dependencies in lib/libc.

XXX: this is a temporary workaround. i'm working on cleaning up how
the DPSRCS stuff is used throughout the tree...

bsd.dep.mk: add a dependency for *.d on ${SRCS} ${DPSRCS}. this should fix
some build problems where DPSRCS contains .h files that need to exist to
build the .d file.

document that bsd.dep.mk should be included after anything that might
update SRCS or DPSRCS so that the above works correctly, and actually
ensure this is the case.

Set .NOPATH for all ${DEPENDSRCS} and not just .depend.
Should fix build problem noted by Geoff Wing on current-users@

Use the more "standard" `foo.d' instead of `foo.SUFFIX.dep'; the rules
are simpler and would have helped prevent the previous fubar.
Don't bother using -a with ${MKDEP} to build the individual .d files.

Make all the suffix rules with .c .c.dep (e.g not .cc .cc.cc.dep)

Simplify .*.dep generation by using suffix transforms.
This also fixes a problem in the previous where the .ALLSRC would contain
any other dependencies that .depend had, thus breaking the mkdep invocation.

Provide DEPENDSRCS which effectively contains ".depend *.dep", to be
used in other Makefiles that want to add dependencies for .depend.

Always use the "per source file".dep method to build the .depend file
(that was formerly only used for HOST_CYGWIN.).
Clean up implementation to minimise unnecessary variable munging.
Ensure all .dep files are deleted in cleandepend:.

This allows us to correctly support CPPFLAGS.<file> in make depend, and
whilst this method is marginally slower in the "no existing .depend file"
case, it should be faster in the "rebuilding depend for a subset of
source files" case.

introduce a new $CPPFLAG_ISYSTEMXX that is used to reference c++ system
includes. for GCC3, set this to -I instead of -isystem.

XXX this should really be either not required or a -isystem-cxx, but for
now this is required to build libstdc++-v3, which otherwise complains
heavily about STL headers not being C code(!)

whitespace cleanup

Add missing } for rev. 1.43.

Also recognize cpp files as C++ files for CYGWIN case.

recognize .cpp as c++ files.

Back this out until I know why it does not work.

Add .cpp dependency rules.

Fix _HOST_CYGWIN lossage.

Hacks for limited command and environment space (John Gordon)

The traditional C preprocessor is fixed in GCC 3.3 now, so no need
to skip -traditional-cpp for HAVE_GCC3.

Oops, AINC actually is still used; put it back.

The MIPS toolchain now defines __ABICALLS__ when abicalls are in use,
and the sources now use that define, so there is no need for us to define
ABICALLS. Since that was the only use for the AINC variable, garbage-collect
it.

Don't use -traditional-cpp if HAVE_GCC3.

If DESTDIR is set, do a similar nostdinc dance for the standard C++ include
directory.

Improve readability and reduce redundant redundancy in share/mk; add some
descriptive comments. The guts of hostprog, lib, and prog are mostly
unchanged; this will be done in another pass.

Make several things work properly with UNPRIVILEGED set, and make the
install-time "cmp" logic work for MANZ. Also reimplement INCS{DIR,NAME}_foo
(requested by wiz) in a backwards compatible way.

Reviewed by christos.

Rather than explicitly saying "clean cleandir:" all the time, make clean
a dependency of cleandir (so that "make cleandir" implies "make clean").

Make "distclean" a REAL synonym for "cleandir" by actually aliasing it
in <bsd.own.mk>, rather than sprinkling it in all the .mk files (and
some Makefiles throughout the tree).

Make `dependall' play nicely with SUBDIR, using a hack similar to `realinstall'
for both `depend' and `all'.
Also, remove the old hack that invokes an extra shell for .depend, now that
make(1) has been fixed.

Add missing "\" in two line shell command.

Pass -traditional-cpp to mkdep for assembler files,
as in the actual compilation (${COMPILE.S} rule in sys.mk).

branches: 1.27.4;
correct previous fix:
- add CLEANDEPEND variable for stuff which should be cleaned out
in "cleandepend" phase.
- add it to the files removed during the cleandepend phase.

Change CFLAGS to AFLAGS for mkdep of .S/.s files. Fixes "make depend"
on pmax kernels (and doesn't break "make depend" on entire tree).

Use :Q to quote arguments to "echo" so that quote marks don't fall out of
the printed mkdep command.

Our make can't actually turn off implicit rules per-target, and the
"depend:" rule had no actual commands to execute, so it used the implicit
".c:" rule in gas.new (which has a depend.c). Add a command here -- just
"true" -- that prevents use of implicit rules. This may need a new
.-option in make(1) to be done Right.

Kill spaces in the $$files check introduced by borrowing the C++ rule for
ObjC.

Add dependency rule for Objective-C files.

add distclean as a synonym for cleandir

Automatically add the .c files corresponding to .l and .y files to DPSRCS.
Automatically add DPSRCS to CLEANFILES.

Remove cruft.

Set the .NOPATH flag for the .depend target.
