9SoftFloat is a software implementation of floating-point that conforms to
10the IEC/IEEE Standard for Binary Floating-Point Arithmetic.  SoftFloat is
11distributed in the form of C source code.  Compiling the SoftFloat sources
12generates 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
20The 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
27Other files in the package comprise the source code for SoftFloat.
28
29Please be aware that some work is involved in porting this software to other
30targets.  It is not just a matter of getting `make' to complete without
31error messages.  I would have written the code that way if I could, but
32there are fundamental differences between systems that I can't make go away.
33You should not attempt to compile SoftFloat without first reading both
34`softfloat.txt' and `softfloat-source.txt'.

36At the time of this writing, the most up-to-date information about
37SoftFloat and the latest release can be found at the Web page `http://
38HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'.
