New port: mac68ksf - Macintosh 68k softfloat.

This commit is all the Makefile glue for the new port which is the mac68k
port with MKSOFTFLOAT set to "yes".

As posted here:
https://mail-index.netbsd.org/port-mac68k/2025/10/14/msg001037.html

flt_rounds.S is only used for gcc_s softfloat.

libc/softfloat (the default) uses softfloat/flt_rounds.c.

Switch over m68k soffloat build to libc/softfloat.

m68k would previously use softfloat functions contained in libgcc_s.

This change aligns m68k with other platforms built with softfloat.

It is still possible to build the gcc_s softfloat impementation by setting
MKSOFFTFLOAT=yes MKLIBCSOFTFLOAT=no

Addresses PR/59393.

Add m68k assembler version of __muldi3().

This is intended for 68060:
- GCC does not emit __muldi3() for 68020-40, that have 32 * 32 --> 64 mulul
- mulsl (and moveml), used in this code, are not implemented for 68010

In comparison with that from compiler_rt, this version saves:
- 12% of processing time
- 12 bytes of stack
- 50 bytes of code size
Also, slightly faster, memory saving, and smaller than libgcc version.

By examining with evcnt(9), __muldi3() is invoked more than 1000 times per
sec by kernel, which should justify to introduce assembler version of this
function.

Restrict usage of m68k assembler versions of {,u}divsi3 and {,u}divsi3 to
kernel and bootloader for 68010.

They requires a special calling convention to udivsi3, and cannot to be
mixed up in normal routines provided by libgcc or compiler_rt. Although,
there's no problem for using them in a controlled situation, i.e., kernel
and standalone programs.

Note that this does not affect at all m68k ports other than sun2, since
codes generated by gcc do not call these routines.

Assembler files are moved from common/lib/libc/arch/m68k/gen to
sys/lib/libkern/arch/m68k in order not to be compiled in libc.

Unify signbitl implementations.
(Unclear why they were different, it was only the comments that
differed)

Add a comment describing why the generic version works for both 80-bit
and 128-bit double.

branches: 1.35.12;
provide a common softfloat fenv implemenation and use it for softfloat builds.
restore ABI compatibility with previous releases for ieeefp.h on sh3.
add namespace.h protection for all the fenv interfaces.
use MKSOFTFLOAT on sh3 instead of assuming softfloat.
standardize on comparing MKSOFTFLOAT with "no".
remove the arm-specific softfloat fenv code (which also had several bugs).
fix logic errors in the arm hardfloat feraiseexcept() and feupdateenv().

branches: 1.34.2;
Sync with compat and remove dup implementations of ldexp and modf, switching
mips and m68k to the compat copies.

branches: 1.33.8;
Merge riastradh-drm2 to HEAD.

Cleanup. hardfloat stuff is now in its own directory

branches: 1.31.6; 1.31.10;
Add TLS support for m68k.

branches: 1.30.6;
Rename ${SRCS.{alpha,arm,...}.gen} to ${LSRCS.{alpha,arm,...}.gen} because
they ended up in ${LSRCS}, not ${SRCS}. ${SRCS.*} namespace will be used
for more useful things. No functional changes intended.

Add no/op routines for m68000 for the sticky, mask, and round settings.

build frexp_ieee754 in the "compat" subtree
(The Makefile logics for ldexp and modf is too involved for me to deal
with this now.)

Welcome to the new compat layout.

Push back the descriptions of NaN formats, and descriptions of the
distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.

IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.

branches: 1.25.2;
Add support to build the mac68k port with soft-float enabled (i.e., setting
MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work
in machines with the 68040LC chip (those that have the FPU bug).

All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>,
with some very minor changes by me; the patches were being posted to the
port-mac68k mailing list. It has been tested for a long time by several
users, including me.

I have just verified that regular releases, as well as soft-float ones,
continue to build.

There have been no objections to this patch since I asked for them in July
in the port-mac68k list.

* Turn isinf(3) and isnan(3) into C99-style macros.
* Make it possible for ports to override these (i.e., VAX).
* Remove isnanl(), which was internal to libc only.

Add C99 fpclassify(), isfinite(), isnormal(), and signbit() macros.

Use the generic `long double' == `double' versions on m68000.

Add __infinityf and __infinityl, float respectively long double analogs
of __infinity.

replace __longjmp14 asm-implementation with __longjmp14 C-implementation
uses setcontext instead of __sigreturn14
fixes longjmp/siglongjmp when !COMPAT_16

* Since there is no single portable IEEE 754 format for a long double,
keep a common implementation of isinfl() and isnanl() to be used by
platforms where `long double' == `double'; move others into
machine-dependent code.
* In due course, consider __VFP_FP__ on arm.

Rework how dependency generation is performed:

* 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".

Build _isinfl() and _isnanl().

Rename ieee754_function.c to function_ieee754.c, following the convention
used in exec_format.c, loadfile_format.c, subsys_machdep.c etc.
Per discussion with Christos.

Merge the nathanw_sa branch.

Clean up some rampant code duplication wrt ieee number handling:
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).

Don't compile softfloat or integer support routines on 68000
machines, they have this support already in libgcc.

branches: 1.12.6;
C99: Define a NAN macro in <math.h> which evaulates to a constant expression of
a single-precision quiet NaN; only to be defined on platforms that do support
this value.

Reimplement the FSCALE version as C-with-assembler. (Make the compiler deal
with ABI crap.)

Separate isnan() into a separate module, and make isinf()/isnan() use ieee.h.

Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

Update for signal changes.

Fix typo, which resulted in always compiling the M68040/M68060-version
of ldexp.

branches: 1.6.2;
ieee.h and ldexp.c taken from the powerpc port, for the benefit of
68040 and 68060 owners.
With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp()
doesn't use excessive amounts of system cpu time.
Without any of those defines, the normal assembler version using FSCALE is
included, for the benefit of M68020 and M68030 users, or M68040/M68060 users
where the ldexp performance is no bottleneck.
[Its not yet worked out how to include both library versions in a binary
distribution, but you can build your own from source now if you need it.]
For details, look at PR 3105.

Remove the duplicated __builtin_saveregs function.
We only need it in src/gnu/usr.bin/gcc/libgcc/libgcc2.c.

m68k sig{set,long}jmp from Henric Jungheim (uhenric@mcl.ucsb.edu) as
followup to GNATS report port-amiga/1009.
Passes regression tests.
I added a NetBSD string and changed jbra to jra.

Added __flt_rounds(), fp{get,set}{round,mask,sticky}().

don't forget inifinity.c

AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.

Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.

On ports without __HAVE_LONG_DOUBLE, make fabsl alias fabs.

For some reason, fabs lives in libc, not in libm, and our tests now

Add support to build the mac68k port with soft-float enabled (i.e., setting
MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work
in machines with the 68040LC chip (those that have the FPU bug).

All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>,
with some very minor changes by me; the patches were being posted to the
port-mac68k mailing list. It has been tested for a long time by several
users, including me.

I have just verified that regular releases, as well as soft-float ones,
continue to build.

ieee.h and ldexp.c taken from the powerpc port, for the benefit of

With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp()
doesn't use excessive amounts of system cpu time.
Without any of those defines, the normal assembler version using FSCALE is
included, for the benefit of M68020 and M68030 users, or M68040/M68060 users
where the ldexp performance is no bottleneck.
[Its not yet worked out how to include both library versions in a binary
distribution, but you can build your own from source now if you need it.]

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

On m68000, all code is compiled softfloat, so functions
that return floats must do so in integer registers, as the
pre-SVR4 ABI code did. So in these functions we ignore
__SVR4_ABI__ if __HAVE_68881__ is not also set.

Pull over rev. 1.5 of the i386 version (../../i386/resumecontext.S),
quoting Matthias Drochner:

> -check for a NULL uc_link before calling setcontext(2); do a real exit(3)
> instead with exit handlers and all that
> -If setcontext(2) returns (which it shouldn't), do an _exit(-1) rather
> than relying on a sensible return value to use as exit code. Makes
> it less likely that an ucontext corruption goes unnoticed.

This fixes regress/lib/libc/context for m68k.

Thanks to Steve Woodford for optimization hints.

Fix comment typo, and convert to C-style comments.

Merge the nathanw_sa branch.

branches: 1.1.2;
file resumecontext.S was initially added on branch nathanw_sa.

Remove the duplicated __builtin_saveregs function.
We only need it in src/gnu/usr.bin/gcc/libgcc/libgcc2.c.

Builtin saveregs returns void *, not void.

Add missing prototypes. From Bernd.

Revert this.

inline call to sigreturn original idea from jason downs <downsj@CSOS.ORST.EDU>
we want this to be done for everything including non-PIC code as longjmp()
does non-standard things with regs and wouldn't like it if the user replaced
the sigreturn() stub.

branches: 1.2.2;
update to use sigaltstack.
