Hauser 7129203Scognet1998 December 13 8129203Scognet 9129203Scognet 10129203ScognetSoftFloat is a software implementation of floating-point that conforms to 11129203Scognetthe IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is 12129203Scognetdistributed in the form of C source code. Compiling the SoftFloat sources 13129203Scognetgenerates two things: 14129203Scognet 15129203Scognet-- A SoftFloat object file (typically `softfloat.o') containing the complete 16129203Scognet set of IEC/IEEE floating-point routines. 17129203Scognet 18129203Scognet-- A `timesoftfloat' program for evaluating the speed of the SoftFloat 19129203Scognet routines. (The SoftFloat module is linked into this program.) 20129203Scognet 21129203ScognetThe SoftFloat package is documented in four text files: 22129203Scognet 23129203Scognet softfloat.txt Documentation for using the SoftFloat functions. 24129203Scognet softfloat-source.txt Documentation for compiling SoftFloat. 25129203Scognet softfloat-history.txt History of major changes to SoftFloat. 26129203Scognet timesoftfloat.txt Documentation for using `timesoftfloat'. 27129203Scognet 28129203ScognetOther files in the package comprise the source code for SoftFloat. 29129203Scognet 30129203ScognetPlease be aware that some work is involved in porting this software to other 31129203Scognettargets. It is not just a matter of getting `make' to complete without 32129203Scogneterror messages. I would have written the code that way if I could, but 33129203Scognetthere are fundamental differences between systems that I can't make go away. 34129203ScognetYou should not attempt to compile SoftFloat without first reading both 35129203Scognet`softfloat.txt' and `softfloat-source.txt'. 36129203Scognet 37129203ScognetAt the time of this writing, the most up-to-date information about 38129203ScognetSoftFloat and the latest release can be found at the Web page `http:// 39129203ScognetHTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'. 40129203Scognet 41
