RevisionDateAuthorComments
 1.8  07-Jul-2011  matt Don't define a new enum. Just #define round_* to their FP_Rx instead.
 1.7  04-Jul-2011  matt Add __floatunsidf __floatunsisf __floatunsitf routines.
XXX i think they are correct but not sure.
 1.6  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.
 1.5  11-May-2006  mrg branches: 1.5.10;
if SOFTFLOAT_FOR_GCC is not defined, don't declare float_detect_tininess.
 1.4  12-May-2002  bjh21 Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new
variable, float_exception_mask (#defined to _softfloat_float_exception_mask)
contains the current exception mask.
Also make the argument to float_raise into an fp_except.
Also synchronise file header comments between files.
 1.3  06-May-2002  bjh21 Consistently declare the types of float_rounding_mode and float_exception_flags
as fp_rnd and fp_except respectively.
 1.2  04-Mar-2002  jmc branches: 1.2.2;
Move names for softfloat lib that _Qp functions call into _softfloat_
namespace
 1.1  05-Feb-2002  jmc Add softfloat and quad softfloat setup for sparc64 (thanks to Andrey Petrov
for most of this. I just integrated the build).

This adds proper functions for the _Qp* parts of the sparc64 ABI (which
handle quad softfloat). The routines work but need additional testing.
However if the compiler calls these currently bad things (core dumps)
will happen as gcc 2.95.3 generates bad calls for these.

Until that problem is fixed in the toolchain -msoft-quad-float cannot be
enabled as the default option for all builds (but the routines need to be
in libc as libgcc contains some references to these and anything including
it via --whole-archive will need the symbols to at least resolve).
 1.2.2.3  21-Jun-2002  nathanw Catch up to -current.
 1.2.2.2  22-Mar-2002  nathanw Catch up to -current.
 1.2.2.1  04-Mar-2002  nathanw file softfloat.h was added on branch nathanw_sa on 2002-03-22 20:41:56 +0000
 1.5.10.1  09-Jan-2008  matt sync with HEAD
