Hauser 615144b0fSOlivier Houchard1998 December 13 715144b0fSOlivier Houchard 815144b0fSOlivier Houchard 915144b0fSOlivier HouchardSoftFloat is a software implementation of floating-point that conforms to 1015144b0fSOlivier Houchardthe IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is 1115144b0fSOlivier Houcharddistributed in the form of C source code. Compiling the SoftFloat sources 1215144b0fSOlivier Houchardgenerates two things: 1315144b0fSOlivier Houchard 1415144b0fSOlivier Houchard-- A SoftFloat object file (typically `softfloat.o') containing the complete 1515144b0fSOlivier Houchard set of IEC/IEEE floating-point routines. 1615144b0fSOlivier Houchard 1715144b0fSOlivier Houchard-- A `timesoftfloat' program for evaluating the speed of the SoftFloat 1815144b0fSOlivier Houchard routines. (The SoftFloat module is linked into this program.) 1915144b0fSOlivier Houchard 2015144b0fSOlivier HouchardThe SoftFloat package is documented in four text files: 2115144b0fSOlivier Houchard 2215144b0fSOlivier Houchard softfloat.txt Documentation for using the SoftFloat functions. 2315144b0fSOlivier Houchard softfloat-source.txt Documentation for compiling SoftFloat. 2415144b0fSOlivier Houchard softfloat-history.txt History of major changes to SoftFloat. 2515144b0fSOlivier Houchard timesoftfloat.txt Documentation for using `timesoftfloat'. 2615144b0fSOlivier Houchard 2715144b0fSOlivier HouchardOther files in the package comprise the source code for SoftFloat. 2815144b0fSOlivier Houchard 2915144b0fSOlivier HouchardPlease be aware that some work is involved in porting this software to other 3015144b0fSOlivier Houchardtargets. It is not just a matter of getting `make' to complete without 3115144b0fSOlivier Houcharderror messages. I would have written the code that way if I could, but 3215144b0fSOlivier Houchardthere are fundamental differences between systems that I can't make go away. 3315144b0fSOlivier HouchardYou should not attempt to compile SoftFloat without first reading both 3415144b0fSOlivier Houchard`softfloat.txt' and `softfloat-source.txt'. 3515144b0fSOlivier Houchard 3615144b0fSOlivier HouchardAt the time of this writing, the most up-to-date information about 3715144b0fSOlivier HouchardSoftFloat and the latest release can be found at the Web page `http:// 3815144b0fSOlivier HouchardHTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'. 3915144b0fSOlivier Houchard 40
