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' program for evaluating the speed of the SoftFloat
|
||
|
|
routines. (The SoftFloat module is linked into this program.)
|
||
|
|
|
||
|
|
The SoftFloat package is documented in four text files:
|
||
|
|
|
||
|
|
softfloat.txt Documentation for using the SoftFloat functions.
|
||
|
|
softfloat-source.txt Documentation for compiling SoftFloat.
|
||
|
|
softfloat-history.txt History of major changes to 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://
