Hauser 7189251Ssam1998 December 13 8189251Ssam 9189251Ssam 10189251SsamSoftFloat is a software implementation of floating-point that conforms to 11189251Ssamthe IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is 12189251Ssamdistributed in the form of C source code. Compiling the SoftFloat sources 13189251Ssamgenerates two things: 14189251Ssam 15189251Ssam-- A SoftFloat object file (typically `softfloat.o') containing the complete 16189251Ssam set of IEC/IEEE floating-point routines. 17189251Ssam 18189251Ssam-- A `timesoftfloat' program for evaluating the speed of the SoftFloat 19189251Ssam routines. (The SoftFloat module is linked into this program.) 20189251Ssam 21189251SsamThe SoftFloat package is documented in four text files: 22189251Ssam 23189251Ssam softfloat.txt Documentation for using the SoftFloat functions. 24189251Ssam softfloat-source.txt Documentation for compiling SoftFloat. 25189251Ssam softfloat-history.txt History of major changes to SoftFloat. 26189251Ssam timesoftfloat.txt Documentation for using `timesoftfloat'. 27189251Ssam 28189251SsamOther files in the package comprise the source code for SoftFloat. 29189251Ssam 30189251SsamPlease be aware that some work is involved in porting this software to other 31189251Ssamtargets. It is not just a matter of getting `make' to complete without 32189251Ssamerror messages. I would have written the code that way if I could, but 33189251Ssamthere are fundamental differences between systems that I can't make go away. 34189251SsamYou should not attempt to compile SoftFloat without first reading both 35189251Ssam`softfloat.txt' and `softfloat-source.txt'. 36189251Ssam 37189251SsamAt the time of this writing, the most up-to-date information about 38189251SsamSoftFloat and the latest release can be found at the Web page `http:// 39189251SsamHTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'. 40189251Ssam 41189251Ssam
