Package Overview for SoftFloat Release 2
John R. Hauser
1997 June 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' executable program for evaluating the speed of the
SoftFloat routines. (The SoftFloat module is linked into this program.)
The SoftFloat package is documented in three text files:
softfloat.txt Documentation for using the SoftFloat functions.
softfloat-source.txt Documentation for compiling 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'.
