4This is a modified version of part of John Hauser's SoftFloat 2a package.
5This version has been heavily modified to support its use with GCC to
6implement built-in floating-point operations, but compiling
7softfloat.c without SOFTFLOAT_FOR_GCC defined should get you the same
8results as from the original.

10SoftFloat is a software implementation of floating-point that conforms to
11the IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is
12distributed in the form of C source code. Compiling the SoftFloat sources
13generates two things:
14
15-- A SoftFloat object file (typically `softfloat.o') containing the complete
16 set of IEC/IEEE floating-point routines.
17
18-- A `timesoftfloat' program for evaluating the speed of the SoftFloat
19 routines. (The SoftFloat module is linked into this program.)
20
21The SoftFloat package is documented in four text files:
22
23 softfloat.txt Documentation for using the SoftFloat functions.
24 softfloat-source.txt Documentation for compiling SoftFloat.
25 softfloat-history.txt History of major changes to SoftFloat.
26 timesoftfloat.txt Documentation for using `timesoftfloat'.
27
28Other files in the package comprise the source code for SoftFloat.

30Please be aware that some work is involved in porting this software to other
31targets. It is not just a matter of getting `make' to complete without
32error messages. I would have written the code that way if I could, but
33there are fundamental differences between systems that I can't make go away.
34You should not attempt to compile SoftFloat without first reading both
35`softfloat.txt' and `softfloat-source.txt'.

37At the time of this writing, the most up-to-date information about
38SoftFloat and the latest release can be found at the Web page `http://
39HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'.
