MFC r270976: Allow standalone debug for non-default ${PROG} targets

This allows WITH_DEBUG_FILES to produce standalone debug for the ELF
runtime linker.

We previously disabled standalone debug files for bsd.prog.mk consumers
that included a non-default ${PROG} target, but this is not required.

Consumers that do not support standalone debug are still handled by
disabling it for statically linked binaries, and for those that specify
a non-default binary format.

Create a private library directory (LIBPRIVATEDIR) for libraries which
we don't want to expose but which can't or shouldn't be static.

To mark a library as private, define PRIVATELIB in its Makefile. It
will be installed in LIBPRIVATEDIR, which is normally /usr/lib/private
(or /usr/lib32/private for 32-bit libraries on 64-bit platforms).

To indicate that a program or library depends on a private library,
define USEPRIVATELIB in its Makefile. The correct version of
LIBPRIVATEDIR will be added to its run-time library search path.

Add a new knob WITH_DEBUG_FILES to control the building of standalone
debug files for userland programs and libraries. The "-g" debug flag
is automatically applied when WITH_DEBUG_FILES is set.

The debug files are now named ${prog}.debug and ${shlib}.debug for
consistency with other systems and documentation. In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
debug files.

Thanks to everyone who contributed changes, review, and testing during
development.

Always define and use PROGNAME

This avoids having separate cases in the install rule for PROGNAME set and
not set. This is a minor cleanup in advance of further support for
standalone debug files.

Make sure to set OBJS consistently in the cases where SRCS is and isn't
already defined. Setting it with "+=" makes it possible for other make
scripts (e.g. bsd.dtrace.mk) to include additional object files in the
linker arguments.

Remove support for installing 1aout section manpages.

Explicitly specify that the beforelinking target depends on the

Also define SHLIB_NAME_FULL to denote ${SHLIB_NAME}.debug if
DEBUG_FILES is set and ${SHLIB_NAME} otherwise, which helps avoid
obfuscating the compilation and linking rules.

- CTF knob is now implemented using common scheme: MK_CTF=yes/no is

- fix WITH_CTF when specified in /etc/src.conf [1]
- CTFCONVERT_CMD=... is a hack (should be defined to empty string instead):
make(1) should be taught to ignore empty commands silently in compat mode
(as it does in !compat mode, GNU make also silently ignores empty commands)

When building WITH_CTF=1, print the ctf executable that's going to be
run. This makes the 'ctfconvert' and 'ctfmerge' programs show up during
a build when compiling a kernel, a library or a program.

Sponsored by: The FreeBSD Foundation

WITH_CTF can now be specified in src.conf (not recommended, there
are some problems with static executables), make.conf (would also
affect ports which do not use GNU make and do not override the
compile targets) or in the kernel config (via "makeoptions
WITH_CTF=yes").

Additional (related) changes:
- propagate WITH_CTF to module builds
- do not add -g to the linker flags, it's a noop there anyway
(at least according to the man page of ld)
- do not add -g to CFLAGS unconditionally
we need to have a look if it is really needed (IMO not) or if there
is a way to add it only when WITH_CTF is used

Note: ctfconvert / ctfmerge lines will not appear in the build output,
to protect the innocent (those which do not build with WITH_CTF would
see the shell-test and may think WITH_CTF is used).

Also add DEBUG_FLAGS to CXXFLAGS if defined.

Add support for the Compact C Type (CTF) conversions throughout FreeBSD's
system makefiles.

Note that the CTF conversion defaults to off. We may choose to change this
default later if DTrace proves popular and people are prepared to wear
the compilation performance impact of compiling with debug symbols all the
time.

Setting NO_CTF in the make args or user environment turns off CTF conversion.
Even if we choose to default CTF generation to on later, we still need
NO_CTF so that the buildworld process can bootstrap the tools without
needlessly generating CTF data for temporary tools.

Setting WITH_CTF in the make args or user environment (and _NOT_ in
/etc/make.conf) is the only way to enable CTF data conversion. Nore that
this can't be implemented the same way that the WITH_ and WITHOUT_ stuff
is implemented throughout the buildworld because the CTF conversion needs
to work when building a simple object without a Makefile, using the
default rules in sys.mk.

Typing 'make test.o' with no makefile and just a source file test.c
should work. Also, typing 'make WITH_CTF=1 test.o without a makefile and
just a source file test.c should work and produce an object with a CTF
elf section. Typing 'make WITH_CTF=1 CFLAGS=-g test.o' without a makefile
and just a source file test.c should produce an object with both a CTF
elf section and the debug elf sections.

In the FreeBSD build where more .mk files are used than just sys.mk
which is included my make by default, the use of DEBUG_FLAGS is the
correct way to enable a debug build. The important thing to note here
is that it is the DEBUG_FLAGS setting that prevents libraries and
programs from being stripped on installation. So, for the addition of
CTF data conversion, setting DEBUG_FLAGS to contain -g, without NO_CTF,
will cause the ctfconvert and ctfmerge build programs to be executed
also with the -g arg so that debug symbols are retained rather than
being removed after the CTF data elf section has been added.

non-bsd.subdir.mk makefiles runs `afterinstall' target _after_ `install'
in SUBDIRs, like we do in bsd.subdir.mk. Nothing depended on the wrong
order anyway.

Fixed `distribute' targets (except for the bsd.subdir.mk version) so that
they do not depend on _SUBDIR; `distribute' calls `install' which already
depends on _SUBDIR.

De-standardize `maninstall', otherwise manpages would be installed twice.

Added bsd.init.mk (like in NetBSD) that handles the inclusion
of ../Makefile.inc and bsd.own.mk from all bsd.*.mk files that
"build something".

Back out bsd.own.mk,v 1.15: moved OBJFORMAT initialization back

and removed MACHINE_ARCH initialization (it's hard to see from
looking at the commitlogs what the problem was at the time, but
now it serves no purpose).

Protect bsd.obj.mk from repetitive inclusion. Prohibiting the

broken. I will temporarily unconnect it from build until
I'm working on the fix.

Obviate the need to set the COMPILER_PATH and LIBRARY_PATH in Makefile.inc1

TOOLS_PREFIX, when building cross-tools.

Fixed regression in Makefile.inc1,v 1.203 (-nostdinc). This clobbered target

in system headers.

(Attempt to move the "-nostdinc -I..." part of CFLAGS into the new CINCLUDES

Bring in the WARNS directive from NetBSD, localized in a new bsd.sys.mk

The idea is that WARNS can be set in Makefile.inc or in individual
Makefiles as they become clean, to prevent the introduction of new
warnings in the code (-Werror is added by default when WARNS > 0).

This behaviour can be overridden with the following two knobs:
NO_WARNS disables the checking of WARNS completely
NO_WERROR disables the addition of -Werror to the flags.

Additionally, setting WFORMAT to 1 (in makefiles) and/or defining
FORMAT_AUDIT (by the user) will enable increased checking of format

Support Objective C almost as well as C++.

Notes:
- We no longer use -fgnu-runtime in bsd.lib.mk, since it is the default
and bsd.lib.mk is the wrong place to override it.
- Gnu C doesn't have a special compiler driver for Objective C like it
does for C++. The defaults are suitable for Gnu C. Use `OBJCLIBS='
in /etc/make.conf for POC.

Moved lex and yacc source handling from bsd.prog.mk to bsd.dep.mk
so that it applies to libraries (and lkms) as well as programs.

Regress to generating foo.c from foo.y via y.tab.c for crufty applications
that want a y.tab.h file. This want must be specified by putting y.tab.h
in SRCS (and defaulting to or putting -d in YFLAGS). This only works if
there is only one yacc parser, of course. One improvement: copy y.tab.c
to foo.c instead of renaming it, so that `#line...y.tab.c' statements in
it refer to an existing file.

Regress to not generating explicit rules for .l and .y sources containing
slashes. This case is unusual and hard to handle properly.

Don't generate an unused dependency when -d is not in YFLAGS.

Oops, the symlink from y.tab.h doesn't work until its target exists.

Fudge local variables better in the yacc rules so that multiple yacc
sources are handled properly.

Generate explicit rules and other infrastructure for lex and yacc
sources. This will be used to fix `make -jN' races in many
Makefiles in /usr/src, and to simplify these and other Makefiles.

To get the fixes and simplifications, application Makefiles should
put the raw lex and yacc source names (foo.l and bar.y) in SRCS and
not put the names of any generated files in SRCS or CLEANFILES. A
few Makefiles already do this, although it didn't actually work before
(mkdep couldn't create complete dependencies because there is no
intermediate .c file for the .y.o and .l.o implicit rules).

Complications: if bar.y is in SRCS and -d is in YFLAGS, then bar.h
will be generated whether or not it is used, even if this clobbers a
real source file. This is so that bar.c can be generated using the
-j-safe and debugger-friendly -o option to YACC. There are smaller
warts for handling y.tab.h. y.tab.c and lex.yy.c are not supported.

Support new version of global.

Introduce the 'regress' target.

Silently approved by: -hackers, -current

Removed support for now-unused FreeBSD misfeature DPSRCS.

Fixed dependency of ${PROG} on ${DPSRCS}. There were various races
for `make -j'. There are one-off fixes for the problem in a few
Makefiles, e.g., amd/amq/Makefile.

Removed clean target. Simply add to CLEANFILES so that the default target
in bsd.obj.mk works.

Limit check for target to smaller section of makefile.

Don't create a ${PROG} target if it already exists.

Postpone the test for non-emptiness of $PROG, $OBJS and $CLEANFILES
to ``shell time''. The previous version didn't work in
/usr/src7share/man/man4.

Oops, the previous patch was botched.

Oops, rm -f can't handle empty lists.

Don't clean files that we don't create.

Fixed style of empty test.

Include <bsd.libnames.mk> if `checkdpadd' is being made, so that it can
:e checked until it goes away.

Change the BINFORMAT definitions so that they do not depend on sys.mk,
since 2.1.x make(1) apparently does not have the -m switch to set both
the the bsd.*.mk and sys.mk location, and this breaks 'make world' from a
2.1.x system.

A first cut at some rules for building elf shared libs. Of particular
note, using "-Wl,-f" to generate a library objects list doesn't work
anymore since the hack to ld hasn't been incorporated into binutils-2.8.
(and the -f switch is used for something else already)

This is disabled by default, don't panic! :-)

Merge buildworld/installworld patch to Makefile from RELENG_2_2. Patch
a couple *.mk files to enable -current world building on really old
machines (e.g., 2.1.5).

Do not set the application variable LDDESTDIR. Note that it is still honored
in a few places (in bsd.lib.mk and bsd.prog.mk); this merely fixed part of
the brokenness by not setting it here.

This fixes building of secure telnetd when DESTDIR is defined.
(Otherwise, it will try to link libtelnet from ${DESTDIR}/usr/lib.)

Make NOSHARED = no / NOSHARED = NO do what you'd expect.

Change the distribute targets so that a given item in our source tree
can place itself into n distributions, where n >= 1.

Change CXXINCLUDES to use "g++" explicitly. CXXINCLUDES was defined
with ${CXX} at the end; the only problem was, the directory name is
"g++" and ${CXX} is defined as "c++" in sys.mk.

Pass everything in ${LDADD} directly to the linker for `make depend'
to prevent complaints from the compiler about nonexistent libraries.

Removed unused (and almost unusable) support for LDONLY. See ld/rtld
for how to use gcc to invoke the linker only.

Removed `.if 0'ed support for not creating intermediate object files.

Removed unused include of bsd.libnames.mk (LDONLY had the last reference
to it).

Removed stale misplaced comment about MANDEPEND.

Support GLOBAL style tags.

Use `ld -f' (actually `cc -Wl,-f') at `make depend' time to generate
almost perfect dependencies on crt0's and libraries. DPADD and
bsd.libnames.mk should go away soon. Use a new _EXTRADEPEND target
to implement this and to avoid editing of .depend when .depend isn;t
being rebuilt. The afterdepend target doesn't seem to be good for
anything and is now unused.

Fixed LDDESTDIR for the DESTDIR case when ${SHLIBDIR} != /usr/lib.

Added commented-out -nostdlib to LDDESTDIR for the DESTDIR case.
The wrong libraries may be used without this; however it breaks
linkage to crt0 and libc.

Don't use dot in a chown command. The chown command has been a no-op
for years since it is for a symlink.

Revert $FreeBSD$ to $Id$

Removed bogus NOOBJ ifdef which was added in rev.1.18-1.19. SRCS is
for C sources only and must not be set if you don't want C objects.

This should fix PR2748.

This should go in 2.2.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Fixed dependencies on libraries which I broke in rev.1.39 of
bsd.prog.mk and didn't actually fix in rev.1.43 of bsd.lib.mk.
The library names must be defined before they are used in
dependencies.

.TARGETOBJDIR has been removed from make and CANONICALOBJDIR set in
bsd.obj.mk. Also, a make target called objwarn checks to see
if ${.OBJDIR} != ${.CURDIR} and ${.OBJDIR} != ${CANONICALOBJDIR}
and outputs a warning. (No warning for the latter if MAKEOBJDIR or MAKEOBJDIRP
REFIX is set). objwarn is called from all targets in bsd.prog.mk, bsd.kmod.mk,
and bsd.lib.mk.

Reviewed by: bde

Moved definitions of library names from bsd.prog.mk to a new central

Back out the recent DEPEND changes - as Bruce points out, it's bogus.

I'll leave any future Makefile hackery to him since he's clearly thought

Make it possible to turn the depend pass off entirely with a NO_DEPEND

Requested-By: wollman

Add depend to all target so that it's explicit. It's only done once,
even if make all is run multiple times, since the depend rule looks for
an existing .depend file.

[Ee]rrs -> Errs errs, save one process for make clean

Fix comment on .else to match code.

Add LIBFTP.

LIBPCAP -> ${DESTDIR}/usr/lib/libpcap.a

"make distribute" have changed, beware if you use it.

More complete implementation of SUBDIR for programs, libraries and kmods.
`depend' wasn't supported. This seems to have only broken `make depend'
in gnu/usr.bin/ld.

bsd.prog.mk:
Build the man pages in ${MANDEPEND} at build time.

Add new LN_FLAGS variable for making LINKS symbolic and whatnot.

LIBFORMS & LIBSCSI added

NOOBJS was bogus - use the already extant `NOOBJ'.

Add the ability to say `NOOBJS' to indicate that the target has no object
files.

The enclosed patch is a cosmetic change to bsd.prog.mk. When
a program directory has subdirectories, make now prints "===> dir/subdir"
instead of "===> subdir". This is modeled after the rules contained in
bsd.subdir.mk.

Change DISTRIBUTION names. Also make bsd.doc.mk go to doc distribution,
not bin. Hmmm.

Move INSTALL?=install line duplicated into each .mk to sys.mk
instead

Don't use `MKDEP= -p' even for the case of a single source file since we
always make an intermediate object file.

Define LIBEDIT, LIBGCC, LIBKVM, LIBSCRYPT and LIBY.

Comment about missing libraries for LIBDES, LIBKDB, LIBKRB, LIBMP, LIBPC
and LIBPLOT.

Don't define LIBDBM since it was replaced by db in libc.

Remove duplication. ${DESTDIR}/usr/lib/... gives /usr/lib/... even when
DESTDIR is not defined.

Add a new "distribute" target. This is a variant of install, which will
put the stuff into the right "distribution". As default things end up
in "bindist".

Normal (ie: most) makefiles know naught of this.

More commits will follow, which will direct various parts of the tree
into the distribution we want them in.

Some of the grief of being release-engineer is supposed to go away with this.

Use += instead of ?= for setting LDDESTDIR. Some Makefiles, such as
cc/Makefile.inc use (abuse?) LDDESTDIR for their internal libraries
so "?=" hides non-default external libraries. Adding multiple paths
to LDDESTDIR works except it makes it even harder than usual to
decide which libraries will actually be linked against.

Added libmd.a -> LIBMD

LIBDIALOG added

SHAREDSTRINGS support was no longer used and just clutters things up,
removed.

LIBMYTINFO and LIBNCURSES defines added

Add support for DEBUG_FLAGS. If you say something like:

make DEBUG_FLAGS=-g2

You can compile something for debugging at debugging level 2.
It will also take care not to strip the resulting executable(s).

Change all references to LIBTERM and -ltermlib to LIBTERMCAP and -ltermcap

Fix spelling error in little-used target.

Build an intermediate object file even when there is only one source
file. This costs a little space but saves time if the target is rebuilt
a lot, and it stops the target varying with the name of temporary
intermediates.

Use ${ECHO} instead of `echo' so that `make -s' is fairly quiet.

Use ${ECHODIR} instead of echo for printing directory names so that
`make -ss' is very quiet.

Make the install targets obey the INSTALLFLAGS requests in the new
Makefiles.

DANGER WILL ROBINSON!

This will cause repeat installs of certain programs, such as `init' and
`rcp', to fail unless one of the two conditions is met:

1) You are in single-user mode.
2) Your security level is set to 0 or -1.

If you have compiled a kernel from the latest sources, your kernel
security level is set to -1 by default, which will keep `init' from
fiddling with it. You can increase it, but not decrease it, from the
command line with the command `sysctl -w kern.securelevel=<new value>'.
I believe that -1 is the most appropriate value to use while we are still
developing the code, although when we ship it should be changed back to 0.

See init(8) for more information.

Spplat our 1.1.5 `mk' ifiles over the top of the 4.4 ones. So far
