| 1.1 | 10-Sep-2025 |
nat | 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.

for example, HAVE_GCC >= 48 works properly.

symbol lists.

jmmv | branches: 1.4.40;
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.

rearnsha | GCC-3 requires a libcall to support testing for unordered.
|
| 1.2 | 21-May-2002 |
bjh21 | Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit
version into different directories. Which version a given port uses is
controlled by the SOFTFLOAT_BITS make variable. This is set to 64 (which
uses the same code we had before) by default. 32-bit platforms that don't
need extended precision support might get better performance by using 32.
Set the ARM port to use the 32-bit version of SoftFloat, since this is more
than a factor of two faster than the 64-bit version. This should get the
floating-point performance back to what it was in 1.5.

Initial commit of SoftFloat 2a import. This should provide a sensible
mostly-MI floating-point implementation for use by gcc -msoft-float.
It's currently only used by arm26, but should be usable by other ports
without too much hacking, assuming doubles and u_int64_ts are passed and
returned the same way, and FP formats are IEEEish.

ARM EABI (AAPCS) uses different names for the softfloat routines that
the normal GCC ones. So after we redefine softfloat's to be what (old) GCC
wants, we redefined the old GCC names to what ARM EABI want (but only if we
are using ARM EABI). We do this for routines not compiled by softfloat so
can just have these redefinitions in one place.

bjh21 | Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit
version into different directories. Which version a given port uses is
controlled by the SOFTFLOAT_BITS make variable. This is set to 64 (which
uses the same code we had before) by default. 32-bit platforms that don't
need extended precision support might get better performance by using 32.
Set the ARM port to use the 32-bit version of SoftFloat, since this is more
than a factor of two faster than the 64-bit version. This should get the
floating-point performance back to what it was in 1.5.

nat | Shift the high word of floatx80 accordingly on m68k.
This is because gcc will store floatx80 as signbit(1)exponent(15) padding(32)
as opposed to sign and exponent in a short(16 bit) word.

m68k would previously use softfloat functions contained in libgcc_s.
This change aligns m68k with other platforms built with softfloat.

riastradh | libc softfloat: Make SIGFPE for trapped fp exceptions non-ignorable.
In hardfloat, when the kernel delivers SIGFPE for a floating-point
exception trap, if SIGFPE is masked or ignored, it is handled _as if_
SIGFPE were unmasked and had the default signal disposition:
964 /*
965 * If the signal is masked or ignored, then unmask it and
966 * reset it to the default action so that the process or
967 * its tracer will be notified.
968 */
969 const bool ignored = action == SIG_IGN;
970 if (masked || ignored) {
971 mutex_enter(&ps->sa_mutex);
972 sigdelset(mask, signo);
973 sigdelset(&p->p_sigctx.ps_sigcatch, signo);
974 sigdelset(&p->p_sigctx.ps_sigignore, signo);
975 sigdelset(&SIGACTION_PS(ps, signo).sa_mask, signo);
976 SIGACTION_PS(ps, signo).sa_handler = SIG_DFL;
977 mutex_exit(&ps->sa_mutex);
978 }
https://nxr.netbsd.org/xref/src/sys/kern/kern_sig.c?r=1.410#964
In other words, if you have asked for floating-point exception traps
via fpsetmask(3) or feeenableexcept(3), then you can't simply defer
or ignore them at the signal level any more than you can defer or
ignore SIGBUS or SIGSEGV. And if the signal handler returns, it will
restart the instruction and -- if nothing has changed in the set of
trapped floating-point exceptions -- trap again, delivering the same
signal again.
Since we can't lock access to signal dispositions, I don't think we
can guarantee the same effect from userland atomically, but we can
get a close approximation (should be good enough for single-threaded
programs, at least) by mimicking this logic and calling sigqueueinfo
in a loop.

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.

Initial commit of SoftFloat 2a import. This should provide a sensible
mostly-MI floating-point implementation for use by gcc -msoft-float.
It's currently only used by arm26, but should be usable by other ports
without too much hacking, assuming doubles and u_int64_ts are passed and
returned the same way, and FP formats are IEEEish.
