| Revision | Date | Author | Comments |
| 1.2 | 24-Dec-2005 |
perry | Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.
|
| 1.1 | 26-Sep-2004 |
jmmv | 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.

| 1.12 | 29-Sep-2025 |
nat | Fix return values for softfloat functions to appease gcc.
Not sure if it is gcc and m68k only so it wrapped up in defines.
|
| 1.11 | 17-Sep-2025 |
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.
|
| 1.10 | 17-Sep-2025 |
nat | Store 80 bit floats properly on m68k.
The libc/softfloat would store the high word as a short, where as gcc
will store it as a long with the sign and 15 bit exponent in the high bytes.
I had to use the __packed attribute as they were stored with an 8-byte
alignment....Why????
|
| 1.9 | 06-Sep-2025 |
nat | Fix byte ordering for extended longs for softfloat on m68k.
This helps many libc soft float libm tests pass.
|
| 1.8 | 06-Sep-2025 |
nat | Definition is static for libc soft float but not for libgcc_s.

| 1.7 | 01-Sep-2014 |
matt | float32_is_signalling_nan needs a prototype if SOFTFLOATM68K_FOR_GCC is
defined.
|
| 1.6 | 18-Mar-2014 |
riastradh | branches: 1.6.4;
Merge riastradh-drm2 to HEAD.
|
| 1.5 | 18-Jul-2013 |
matt | Coldfire doesn't do FLOATX80
|
| 1.4 | 07-Jul-2011 |
matt | branches: 1.4.2; 1.4.8; 1.4.12;
Don't define a new enum. Just #define round_* to their FP_Rx instead.
|
| 1.3 | 04-Jul-2011 |
matt | Add __floatunsidf __floatunsisf __floatunsitf routines.
XXX i think they are correct but not sure.
|
| 1.2 | 16-May-2006 |
mrg | if SOFTFLOAT_FOR_GCC is not defined, don't declare float_detect_tininess.
