   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.

  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'.

  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'.
