add support for mips and riscv builds in gcc 14.

Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.

Undo previous lwp.h change.

Split __lwp_getprivate_fast and __lwp_*tcb from mcontext.h into a separate
lwp.h file.

distrib/sets/lists: Add a blank comment line between RCS id and body.

This serves as a buffer between RCS id changes and other changes to
the set lists, in an attempt to reduce the pain of merge conflicts
around mass set list changes.

No functional change intended.

branches: 1.93.2;
distrib/lists/sets/comp: Add gcc=12 obsolete entries for gcc-10/*.h.

mark all previously gcc=9 files as obsolete.

also mark a bunch of obsolete gcc headers as "comp-obsolete" "set".

should fix a 'postinstall fix obsolete' issue reported by uwe@.

various updates for GCC 12

- bump some shlibs
- add new header files
- add compiler-version header files
- disable sanitizer libraries for gcc12 for now

Update LLVM build system for 249b40b558955afe5ac2b549edcf2d7f859c8cc9

This enables the use of modules for a significant build performance gain
when building with clang as host compiler or when using HAVE_LLVM=yes.
Switch libc++ to using the copy from the mono-repo.

branches: 1.89.2;
Choose the right compat sets for the platform:
mipsn64 -> o32 n32
mips64 -> o32 64

various updates for GCC 10 support. remove dead gcc7/8 support
and properly mark obsolete files in gcc9/gcc10.

testing on amd64 and shark for GCC 9, and many platforms for GCC 10,
(though not arm yet.)

Install <mips/frame.h>, now needed for dtrace.

branches: 1.86.2;
fix mips and powerpc GCC 9 builds.

mostly support GCC 9 builds. some what tested with GCC 9 but
tested to not break GCC 8 builds for x86, arm*, vax, and sparc*.

Update LLVM to 10.0.0git (01f3a59fb3e2542fce74c768718f594d0debd0da)

gcc 8 set lists updates. i don't appear to have broken gcc 7 builds
but i only tested a couple of them.

give syspkg names to "-unknown-" files under comp category

Revert previous.

The lines look like misapplied patches but I'm told they are correct.

Remove weird lines from set lists.

fix mips64 GCC 7 builds.

add basic gcc-7 support in sets lists and filesystem. mips gained
a header. assumes it's otherwise mostly the same as gcc-7.

- mark gcc=5 files obsolete
- make includes always available, not only when gcccmds
- mark files obsolete consistently

mark gcc 4.5 mips files obsolete. should fix failure to obsolete
properly because /usr/include/gcc-4.5 isn't empty.

Update LLVM/Clang build system to r337282.

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

branches: 1.73.2; 1.73.4;
obsolete some GCC 4.8 files.

updates for GCC 6.4: add gcc-6 specific headers, combine some
all-gcc files, bump the shlib versions on new libs.

convert HAVE_GCC handling to modern GCC release numbering:
- HAVE_GCC=5 is now the default (vs. HAVE_GCC=53 we've been using for
GCC 5.4 and GCC 5.5.)
- remove some more GCC 4.8 code. we don't support GCC 4 here.
- adjust set lists to gcc=5 from gcc=53.

add some basic HAVE_GCC=6 handling (totally unused so far.)

Update LLVM build glue for 5.0RC1.

add MIPS-specific clang header file

branches: 1.68.2;
Add missing "compat" qualifier to fix build with MKCOMPAT=no for mips64-e[bl].
Also, add "softfloat" to /usr/lib/{64,o32}/libc_fp_pic.a.

Sort the unsorted sets lists (they should all be correctly sorted now.)

Fix linker script entries for arch64 mips

Mark linker scripts with binutils

sort (sort of)

libc_fp is arch64 only.

build and install libc_fp on mips
use with LD_PRELOAD=/lib/libc_fp.so for FPU use via softfloat

branches: 1.61.2;
set fixes for GCC 5.3.

(only arm is tested so far, but there's a pattern i can see :-)

Add fenv.h for mips.

revert the previous; it wasn't wrong, just a little unusual

fix some merge errors in the previous

now that we only support gcc 4.8, make all the gcc tags just "gcc".
this should help with next-gcc, when we can add back gcc=48 and
gcc=5x tags, as necessary.

obsolete and clean up gcc=3 (3.3), gcc=4 (4.1), and gcc=45 (4.5) sets.

Update some of the set lists to use the compatdir/compatfile
compattestsdir/compattestsfile as well the kmod auto-entry creation.
Remove entries that are now instantiated by the above.

stuff added by blacklist

Consistently tag libasan with gcc=48

Add libasan

Rename sljitarch.h to sljit_machdep.h.

infrastructure for bind-9.10.0-P2:
adding the tools delv and dnssec-importkey
adding libirs to support delv

Drop superflous "picinstall" flag on "obsolete" items

Reported by apb@, thanks!

Mark all _pic.a archive files with the 'picinstall' flag.

This fixes checkflist with MKPICINSTALL=no.

ok christos@.

fix mips64 sets for GCC 4.8.

add GCC 4.8 mips64 subdirs.

add support for GCC 4.8 sets.

Sort entries in strcmp order.

Collapse all the ad.mips* set lists into a single ad.mips which works for
all variations of mips{,64}e{b,l}

Add a new "debug" set that gets built when ${MKDEBUG} is set. On evbarm:
-rw-r--r-- 1 root src 35806068 Jan 16 10:47 base.tgz
-rw-r--r-- 1 root src 57374069 Jan 16 10:48 comp.tgz
-rw-r--r-- 1 root src 101286193 Jan 16 10:49 debug.tgz
...
This allows always building the debugging code and libraries but not
installing it (although now it is placed in the default sets if ${MKDEBUG}
is set

Add sljitarch.h to all mips machines.

branches: 1.38.2; 1.38.8;
Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

- un-obsolete a pair of files we want to remain installed (XXX i wonder
if a way to have "clean builds" not run "postinstall fix obsolete" in
the $DESTDIR so that these sorts of errors will appear as set list
errors instead of being skipped
- fix the list of headers to install for GCC 4.5, based upon the mknative
${G_EXTRA_HEADERS}. XXX move the location of G_EXTRA_HEADERS.

Don't remove the mips a.out entries outright, but instead mark them as
obsolete, so that they will be removed from DESTDIR. Hi, matt@!

We don't install <machine/bsd-aout.h> and <machine/aout_machdep.h> on MIPS
anymore and we don't build elf2aout for MIPS either.

branches: 1.34.8;
Add a bunch of .debug entries, determined by inspecting the equivalent
comp lists.
Inspired by PR 39370

branches: 1.33.12; 1.33.16;
Sync with changes introduced by merging the newlock2 branch.

obsolete db_machdep.h

Add <machine/wchar_limits.h>.

reformat whitespace

Significant overhaul of how the sets are used:

* Add an optional third field to the sets file which is a list of
comma separated keywords that control if the line is printed.
Currently supported keywords
kerberos4 ${MKKERBEROS4} != no
kerberos ${MKKERBEROS} != no
lint ${MKLINT} != no
obsolete ${obsolete} != 0.
In this case, non obsolete files are not printed.
(This will allow future support for builds with variables such as
MKHESIOD and MKYP set to "no".)

* Use sh(1)'s getopts where appropriate, and otherwise cleanup the
various scripts.

* Move defaults for sets.subr from sets.defaults into sets.subr.
Move replicated code for determining stuff such as shlibs type
from various scripts into sets.subr.

* Merge the obsolete.*, krb.*, krb4.* and lint.* into the appropriate
main lists with the relevant third field keyword(s).

Back out change that made libpthread per-platform. It is *intentional*
that the build fails on platforms which do not yet have libpthread support.

Not all ports/archs have pthread support. So split this up by the proper arch's
for determining which ones get the libraries. Tested on dreamcast, macppc
and i386 builds to cover non builds, ad and md mods

Update for nathanw_sa merge.

Catch up to new pmc header files.

Add <machine/int_fmtio.h>.

Add <machine/int_limits.h>.

Add <machine/int_const.h>.

Add <machine/int_mwgwtypes.h>.

Add <machine/int_types.h>.

add <mips/endian_machdep.h>.

Add <machine/lock.h>

Add missing pkg name

Add package names. Later tonight or tomorrow AM, I will post a writeup of
this to tech-{pkg,install}. In short, the pkg names in (new) second
field will be used by the build process under basesrc/src/dist/pkg to
generate PLISTs. The package divisions here may be two finely or coarsely
grained, although I think they're a happy medium -- I will give more
detail/justification in the writeup.

Add <machine/math.h>.

G/C <machine/elf.h>.

branches: 1.13.4;
add ieee.h

Move the elf2{aout,ecoff} manpages to the MI set.

Add a NetBSD RCS tag to each distrib list file.

Add a few missing include files.

Add elf2{aout,ecoff} manpages.

Remove /usr/include/mips/conf.h, and old non-ELF crt* gunk.

g/c regdef.h

Update for bswap.h and byte_swap.h includes.

Set cleanup:
- make all ports egcs; move stuff to mi and shl.*
- fix m68k-based comp sets to use usr/include/$MACHINE (as
usr/include/machine is now a symlink); add directory entries where missing

Add egcs dependencies for mips: stl hdrs, libobjc hdrs, shared libs, manpages.

move crtn.o to comp set

Remove objdump - it's in the mi lists now.

Do datbase normalization on sets/lists/*/* containing shared-library
related files. Partition into three categories:
* shl.mi -- MI sharedlib files present on all ports with shared libs
* shl.aout -- MI sharedlib files present on all ELF ports
* shl.elf -- MI sharedlib files present on all a.out ports

Add rudimentary shl* support to makeflist.
Remove files left empty after shlib normalization.
Add ad.mips where appropriate.
Make libc, libedit numbers consistent (libc.so.12.29, libedit.2.1).
