      3 This is a modified version of part of John Hauser's SoftFloat 2a package.
      4 This version has been heavily modified to support its use with GCC to
      5 implement built-in floating-point operations, but compiling
      6 softfloat.c without SOFTFLOAT_FOR_GCC defined should get you the same
      7 results as from the original.

      3 Package Overview for SoftFloat Release 2a

      9 SoftFloat is a software implementation of floating-point that conforms to
     10 the IEC/IEEE Standard for Binary Floating-Point Arithmetic.  SoftFloat is
     11 distributed in the form of C source code.  Compiling the SoftFloat sources
     12 generates two things:
     13 
     14 -- A SoftFloat object file (typically `softfloat.o') containing the complete
     15    set of IEC/IEEE floating-point routines.
     16 
     17 -- A `timesoftfloat' program for evaluating the speed of the SoftFloat
     18    routines.  (The SoftFloat module is linked into this program.)
     19 
     20 The SoftFloat package is documented in four text files:
     21 
     22    softfloat.txt          Documentation for using the SoftFloat functions.
     23    softfloat-source.txt   Documentation for compiling SoftFloat.
     24    softfloat-history.txt  History of major changes to SoftFloat.
     25    timesoftfloat.txt      Documentation for using `timesoftfloat'.
     26 
     27 Other files in the package comprise the source code for SoftFloat.
     28 
     29 Please be aware that some work is involved in porting this software to other
     30 targets.  It is not just a matter of getting `make' to complete without
     31 error messages.  I would have written the code that way if I could, but
     32 there are fundamental differences between systems that I can't make go away.
     33 You should not attempt to compile SoftFloat without first reading both
     34 `softfloat.txt' and `softfloat-source.txt'.
     35 
     36 At the time of this writing, the most up-to-date information about
     37 SoftFloat and the latest release can be found at the Web page `http://
     38 HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'.
