 1.16  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.
 1.15  27-Feb-2024  christos appease lint
 1.14  29-Mar-2016  martin Avoid warnings (signed/unsigned comparision and unused variable)
 1.13  22-Nov-2013  martin Fix a cast from the lint cleanup that made small exponents (i.e. values < 1)
sign extend wrong and overflow, causing an underflow in all 128 bit sqrt
calculations.
 1.12  10-Jan-2013  matt Add hooks to softfloat to support per-lwp exception state.
 1.11  24-Mar-2012  matt branches: 1.11.2;
Fix a bug introduced by lint cleanup.
 1.10  21-Mar-2012  christos cast to appropriate types.
 1.9  20-Mar-2012  martin Remove initialized but unused variable
 1.8  10-Jul-2011  matt branches: 1.8.2;
Fix so that float128_to_uint64_round_to_zero is defined for sparc64.
(isn't tha a namespace violation?)
 1.7  09-Jul-2011  matt Add SOFTFLOAT_NEED_FIXUNS condition around the float128 fixuns
 1.6  04-Jul-2011  matt Add __floatunsidf __floatunsisf __floatunsitf routines.
XXX i think they are correct but not sure.
 1.5  08-Nov-2007  martin branches: 1.5.20;
When creating unsigned int results, do not distinguish positive versus
negative overflow.
 1.4  08-Nov-2007  martin When converting long double values to integer types, explicitly use the
"round to zero" variants of the softfloat conversion functions.
Add a variant to convert long double to unsigned long - the "to long"
variant checked for overflows that do not apply to unsigned results.
This fixes the regress/lib/libc/convfp tests for sparc64.
 1.3  11-May-2006  mrg branches: 1.3.10;
add128() wants bits64 * as it's 5th argument.
 1.2  26-Jul-2003  salo netbsd.org->NetBSD.org
 1.1  21-May-2002  bjh21 branches: 1.1.4;
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.
 1.1.4.2  21-May-2002  bjh21 Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit

 1.1.4.1  21-May-2002  bjh21 file softfloat.c was added on branch nathanw_sa on 2002-05-21 23:51:09 +0000
 1.3.10.1  09-Jan-2008  matt sync with HEAD
 1.5.20.1  20-May-2011  matt Add float128_to_uint32_round_to_zero
 1.8.2.3  22-May-2014  yamt sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")

 1.11.2.2  20-Aug-2014  tls Rebase to HEAD as of a few days ago.
 1.11.2.1  25-Feb-2013  tls resync with head
