Hauser 6 1.1 bjh21 1998 December 13 7 1.1 bjh21 8 1.1 bjh21 9 1.1 bjh21 SoftFloat is a software implementation of floating-point that conforms to 10 1.1 bjh21 the IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is 11 1.1 bjh21 distributed in the form of C source code. Compiling the SoftFloat sources 12 1.1 bjh21 generates two things: 13 1.1 bjh21 14 1.1 bjh21 -- A SoftFloat object file (typically `softfloat.o') containing the complete 15 1.1 bjh21 set of IEC/IEEE floating-point routines. 16 1.1 bjh21 17 1.1 bjh21 -- A `timesoftfloat' program for evaluating the speed of the SoftFloat 18 1.1 bjh21 routines. (The SoftFloat module is linked into this program.) 19 1.1 bjh21 20 1.1 bjh21 The SoftFloat package is documented in four text files: 21 1.1 bjh21 22 1.1 bjh21 softfloat.txt Documentation for using the SoftFloat functions. 23 1.1 bjh21 softfloat-source.txt Documentation for compiling SoftFloat. 24 1.1 bjh21 softfloat-history.txt History of major changes to SoftFloat. 25 1.1 bjh21 timesoftfloat.txt Documentation for using `timesoftfloat'. 26 1.1 bjh21 27 1.1 bjh21 Other files in the package comprise the source code for SoftFloat. 28 1.1 bjh21 29 1.1 bjh21 Please be aware that some work is involved in porting this software to other 30 1.1 bjh21 targets. It is not just a matter of getting `make' to complete without 31 1.1 bjh21 error messages. I would have written the code that way if I could, but 32 1.1 bjh21 there are fundamental differences between systems that I can't make go away. 33 1.1 bjh21 You should not attempt to compile SoftFloat without first reading both 34 1.1 bjh21 `softfloat.txt' and `softfloat-source.txt'. 35 1.1 bjh21 36 1.1 bjh21 At the time of this writing, the most up-to-date information about 37 1.1 bjh21 SoftFloat and the latest release can be found at the Web page `http:// 38 1.1 bjh21 HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'. 39 1.1 bjh21 40
