There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
register - so FE_UPWARD needs to be 3 and FE_DOWNWARD 2 - otherwise
our libc code for fpsetround(), fpgetround() and __flt_rounds() would
need to be adjust (and become slower). This fixes a failure in the
lib/libc/ieeefp/round regression test.
OK: matt
-DM68040, and -DM68060 into sys/arch/m68k/Makefile.cmachflags and
include from both atari and amiga. Other m68k ports which build
kernels that support multiple CPU types can also switch across to
this.
to check 040/060 FP instructions, and don't call fpu_implode() and
fpu_upd_fpsr() if no vaild emulated result is set otherwise these
functions cause NULL pointer dereference.
Fixes panics triggered by 040/060's FDADD instruction
(which has the same lower 6 bits with fscale instruction)
on 020/030 machines (even with 68881/68882) running kernels
with options FPU_EMULATE.
Problem reported by John Carr on port-sun3.
Should be pulled up to netbsd-4-0, netbsd-4 and netbsd-5.
XXX: m68k 4.0 packages binaries on ftp have this FDADD instruction.
virtual_end, and protection_codes[] to common <m68k/pmap_motorola.h>,

XXX: avail_start and avail_end should also be moved, but it causes

(where MMU is not enabled yet) and make kernel_pmap_store static again.
Also consistently use uintptr_t on address conversion in RELOC() macro.
Tested on hp300 (PA != VA) and news68k (PA == VA).
into modules. By and large this commit:
- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime
the active syscall description in struct lwp. To be used at some future
point to prevent unloading of modules that provide syscalls, while the
syscalls are in use.
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.
Also, kern_sa.c has received partial cleanup. There's still more
to do, though.
we no longer need to guard against access from hardware interrupt handlers.
Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.
remodel old RAS based _lock_cas() implementation for m68010
into genereic atomic_cas_32().
Now sun2 kernel compiles and even works on multiuser. (hehe)
Tested on tme (emulationg 2/120 and 3/150) and (real) 3/80.
sys/arch/m68k/fpsp:
* The fpsp/asm2gas sed script previously hardcoded the fact that
registers needed a '%' prefix, and the 060sp/asm2gas sed scrip
previously did not have rules related to inserting '%' before register
names. Now, both scripts have the same rules, but the rules are
parapeterised to use "$P", which is set to '' or '%' as appropriate.
* Some other minor changes to the sed scripts.
The new asm2gas scripts have been verified to produce identical output
to the old asm2gas scripts, for all inputs in 060sp/dist/*.sa and
fpsp/*.sa, except for some differences inside comments.
Thanks to Izumi Tsutsui for suggesting that these scripts should be
synchronised.
Instead of passing the (un)real system call code and syscall table pointer,
just pass the number of arguments - which is what ktrace really wants.

- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.
This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.
