Fix the behaviour of native and tools gcc when MKPIC=no is specified for
platforms that mknative has determined support shared libraries.
XXX distrib/sets/sets.subr doesn't support MKPIC=no
and exception handling have a chance of working properly.
- creates libgcc, libgcc_eh and libgcc_s
- updates LIBGCC_SPEC to use them appropriately.
There's a hack in here at the moment with respect to libgcc_so in that it
is preferable to link against libgcc_so will only when -shared-libgcc is
specified (the c++ frontend does this automatically.) Configurations where
LINK_EH_SPEC is defined already do this. The gcc configuration for
NetBSD/alpha and another NetBSD platform (I forget which) actually define
LINK_EH_SPEC probably by accident rather than design.
- updates share/mk to use the compiler's knowledge of what needs linking into
libraries and executables. This removes an hppa hack.
- updates the sets for the newly created libgcc* files.
- support for linking against the _pg version of libgcc has been removed.
- Disable symbol versioning (for now)
- Make sure that libiberty knows its being configured with a
cross compiler.
- The CXX_* variables are no longer needed/used.
- LIB2FUNCS_EXTRA gets pulled in via LIB2ADD
- Get LIB1ASMFUNCS and LIB2ASMSRC
- MAYBE_USE_COLLECT2 got renamed to USE_COLLECT2 (but might not
be used)
- Get EXTRA_HEADERS so that we get generate the right paths for
CPPFLAGS
- Get some variables related to shared libgcc
There are three levels of compliance w.r.t. HOSTEXEEXT. (1) built and
installed both wrong, (2) both right, and (3) one right, one wrong.
Most tool builds do (1), i.e., wrong, but not seriously so. This makefile
actually built them the "right" way, leading to error (3), which was fatal.
* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h
* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.
These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

* 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.
the tool build from attempting to build the GCC crtstuff before the
target include files are installed. PR toolchain/23112.
(Note: You would not see the bad behavior described in the PR unless
your .mk files were hacked to configure the toolchain target as
*-*-netbsd*2.0.)
<sys/bootblock.h>:
* Added definitions for the Master Boot Record (MBR) used by
a variety of systems (primarily i386), including the format
of the BIOS Parameter Block (BPB).
This information was cribbed from a variety of sources
including <sys/disklabel_mbr.h> which this is a superset of.
As part of this, some data structure elements and #defines
were renamed to be more "namespace friendly" and consistent
with other bootblocks and MBR documentation.
Update all uses of the old names to the new names.
<sys/disklabel_mbr.h>:
* Deprecated in favor of <sys/bootblock.h> (the latter is more
"host tool" friendly).
amd64 & i386:
* Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
be consistent with the naming convention of the msdosfs tools.
* Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
and it's confusing to have two functionally equivalent bootblocks,
especially given that "ufs" has multiple meanings (it could be
a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).
* Rework pbr.S (the first sector of bootxx_*):
+ Ensure that BPB (bytes 11..89) and the partition table
(bytes 446..509) do not contain code.
+ Add support for booting from FAT partitions if BOOT_FROM_FAT
is defined. (Only set for bootxx_msdos).
+ Remove "dummy" partition 3; if people want to installboot(8)
these to the start of the disk they can use fdisk(8) to
create a real MBR partition table...
+ Compile with TERSE_ERROR so it fits because of the above.
Whilst this is less user friendly, I feel it's important
to have a valid partition table and BPB in the MBR/PBR.
* Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
with other platforms.
* Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
we can boot off FAT partitions.
* Crank version of /usr/mdec/boot to 3.1, and fix some of the other
entries in the version file.
installboot(8) (i386):
* Read the existing MBR of the filesystem and retain the BIOS
Parameter Block (BPB) in bytes 11..89 and the MBR partition
table in bytes 446..509. (Previously installboot(8) would
trash those two sections of the MBR.)
mbrlabel(8):
* Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
to map the MBR partition type to the NetBSD disklabel type.
Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).
* 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".
Replace defined(UNPRIVED) tests with ${MKUNPRIVED} != "no"
Add MKUPDATE; if not no has the same semantics as if UPDATE was defined.
Replace defined(UPDATE) tests with ${MKUPDATE} != "no"
Improve documentation for these and other make flags.
the same as "$TOOLDIR", run "make cleandir" here first.
This should prevent various problems where $TOOLDIR is encoded into the
build process for various tools (lint, groff, texinfo, toolchain),
$TOOLDIR changes, and various programs don't get rebuilt correctly.
Should fix PR [toolchain/21988].
* Clean up how the `${MKTOOLS} == no' check is performed.
* Remove "cleantools"; it made a big assumption about the location of
TOOLDIR that won't be correct in many cases.
program/tool from "FOO" to "TOOL_FOO". The new variables are:

TOOL_GENCAT TOOL_GROFF TOOL_HEXDUMP TOOL_INDXBIB TOOL_INSTALLBOOT

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.
for a 64-bit target on a 32-bit host.
NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.
For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.
This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.
I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.
Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.
- get man_MANS and TEXINFO from binutils/doc/Makefile now, not
binutils/Makefile, as all the binutils docs moved.
both:
- add new "mknative-gcc", "mknative-binutils", and "mknative-gdb"
targets / mknative options to allow regeneration of just one part
of the toolchain.
config.cache depends upon 'include/.stamp configure config.h.in defs.mk.in'
and runs configure. Forcebly remove config.cache before running configure.
This change means that config.cache is (still) retained between "make clean"
(but not "make cleandir") runs, but is flushed if configure or config.h.in
is changed, as the cache may contain incorrect information in that case.
which first lstat(2) the target and return EINVAL if it's a symlink,
and then call ch{flags,mod,own} as appropriate.
Removes the need for hokey code inside the tools themselves...
(as Solaris, Linux and HP/UX all mention they need zlib and it should
be part of libnbcompat, maybe this is a hint for us to get a move on
and do that :)
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.
tools use some features of glob(3) that are not available on
all systems.
* Always include the NetBSD vis(3) in libnbcompat, since vis(3)
is not really standardized, and the vis(3) present on some systems
is different from ours.
* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
in libnbcompat. The host tools use features of the NetBSD versions
which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.
* Add a check for termios.h -- the Heimdal host tools want it.
* Update the README to indicate the current state of building the
host tools on Solaris 8 (for SPARC).
value for _PATH_DEFSHELLDIR. In theory, _PATH_DEFSHELLDIR will also be
used to find csh, but ".SHELL csh" shouldn't be used anywhere in our source
tree, and this make shouldn't be used for other things.
This should cause nbmake to use the right shell for most purposes when
cross-compiling from Solaris.
that's in that directory. Fixes compile issue on (older source ?) arm
systems noted by Richard Earnshaw.
XXX: arguably a better version of sys/exec_elf.h (and others) should
be in ../compat instead, but that's a problem for another day.
up by pk (and fix comments to match):
* A .WAIT here means that only the *immediately preceding* target needs
to be added to the list of "install-foo" targets used to ensure that
dependencies are installed (otherwise much more than is necessary
gets installed during the build process, increasing build time here)
* If building only an individual target such as "dependall-yacc", the
prerequisites may need to be built before running their "install-foo"
targets -- so add a dependency in that case on "dependall-foo".
gdb support (determined by GNU configure).
* Be less verbose if there are no existing toolchain framework files to
compare (suppress grep "file not found" error)
files. This version is capable of generating these files Properly from
a cross host (subject to having tools and target libs/includes available
ahead of time; to be documented).
For now this is a maintainer-tool only; none of the NetBSD build needs to
run msgfmt as of yet. (However, its presence is needed to make the
mknative part of src/tools/toolchain produce the same output as a truly
"native" GNU configury of the toolchain.)
just add the additional commands to the `.configure_done' target.
Also, since the groff distribution Makefiles don't get their dependencies
right, use internal knowledge to add additional target ordering to the
generated makefile. Note, this hack can be removed once our own make(1)
can be invoked in true sequential (i.e. compatible) mode again for subdir
makes.
* Beef up that goo so that for each ".WAIT group" all of the install targets
in the previous group have completed before starting the `all', `depend'
or `dependall' targets.
Provide a target "bootstrap-libgcc", which will create the files
src/gnu/lib/libgcc/${MACHINE_ARCH}.mk
src/gnu/usr.bin/gcc/arch/${MACHINE_ARCH}/tconfig.h
src/gnu/usr.bin/gcc/arch/${MACHINE_ARCH}/tm.h
...enough to allow libgcc to build so that a bootstrap build to DESTDIR can
take place.
