add GCC 14 support for arm64 (only big endian builds so far.)

various updates for GCC 14. maybe not complete for all ports.

x86 should be complete, arm64 might be.


tested with i386 and evbarm64 builds and HAVE_GCC=12, hopefully
won't break existing builds.

fix libtsan_pic.a entry.

Update sets for sanitizer lib[alt]san_preinit.o files.

Add arm/lwp_private.h

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.

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.

GCC sanitizers: only build the sanitizers if $MKGCCCMDS != "no".

there's a minor use-case for the configuration of "building sanitizers
for distribution, but not the compiler", but it's pretty uncommon, and
the latest sanitizers don't build at all on m68000 so enhance the
option to not build /usr/bin/gcc (which simply can't modern GCC on a
sun2) to not build the sanitizers either.

(if we were to split these, MKGCCSANITIZER would be good variable.)

update set lists for far too many files, including fixing MKDEBUG for
a couple of builds.

branches: 1.53.2;
distrib/lists/sets/comp: Add gcc=12 obsolete entries for gcc-10/*.h.

Take a whack at fixing the compat32 set lists for clang build.

This really needs to be automatically derived from the main set
lists; all this copypasta is a maintenance nightmare and I doubt I
got everything after an hour of tweaking.

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@.

lists/aarch64: Obsolete gcc-9 headers

more updates for sets and GCC 12

- renable sanitizer, add new shlib versions, enable tsan for arm64,
including moving some stuff into the per-cpu/arch dir from 'mi'.
- fix mips64, 68k, and ia64
- mark many any-gcc-version things just as "gcc" and remove dups
- mark many gcc=9 only things as obsolete
- mark many gcc=10 only things as obsolete with gcc=12 (more could
be done here.)

various updates for GCC 12

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

Good bye oabi! Tested building earmv7hf.

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.

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.)

G/C arm/atomic.h

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*.

Sort and deduplicate set lists.

Fix aarch64 set for !gcc build

gcc 8 set lists updates. i don't appear to have broken gcc 7 builds

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

mark ./usr/include/g++/bits/aarch64/c++config.h and
./usr/include/g++/bits/arm/c++config.h as "libstdcxx" not "gcc=6".

add gcc-7 specific header.

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

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.

now that we only support gcc 4.8, make all the gcc tags just "gcc".
