Marius Strobl b7e9bee71c While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases  tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.

Package Overview for SoftFloat Release 2a

John R. Hauser
1998 December 13


SoftFloat is a software implementation of floating-point that conforms to
the IEC/IEEE Standard for Binary Floating-Point Arithmetic.  SoftFloat is
distributed in the form of C source code.  Compiling the SoftFloat sources
generates two things:

-- A SoftFloat object file (typically `softfloat.o') containing the complete
   set of IEC/IEEE floating-point routines.

-- A `timesoftfloat' program for evaluating the speed of the SoftFloat
   routines.  (The SoftFloat module is linked into this program.)

The SoftFloat package is documented in four text files:

   softfloat.txt          Documentation for using the SoftFloat functions.
   softfloat-source.txt   Documentation for compiling SoftFloat.
   softfloat-history.txt  History of major changes to SoftFloat.
   timesoftfloat.txt      Documentation for using `timesoftfloat'.

Other files in the package comprise the source code for SoftFloat.

Please be aware that some work is involved in porting this software to other
targets.  It is not just a matter of getting `make' to complete without
error messages.  I would have written the code that way if I could, but
there are fundamental differences between systems that I can't make go away.
You should not attempt to compile SoftFloat without first reading both
`softfloat.txt' and `softfloat-source.txt'.

At the time of this writing, the most up-to-date information about
SoftFloat and the latest release can be found at the Web page `http://
HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'.
