| 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'. | |
