| 9 | SoftFloat is a software implementation of floating-point that conforms to
|
|---|
| 10 | the IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is
|
|---|
| 11 | distributed in the form of C source code. Compiling the SoftFloat sources
|
|---|
| 12 | generates two things:
|
|---|
| 13 |
|
|---|
| 14 | -- A SoftFloat object file (typically `softfloat.o') containing the complete
|
|---|
| 15 | set of IEC/IEEE floating-point routines.
|
|---|
| 16 |
|
|---|
| 17 | -- A `timesoftfloat' program for evaluating the speed of the SoftFloat
|
|---|
| 18 | routines. (The SoftFloat module is linked into this program.)
|
|---|
| 19 |
|
|---|
| 20 | The SoftFloat package is documented in four text files:
|
|---|
| 21 |
|
|---|
| 22 | softfloat.txt Documentation for using the SoftFloat functions.
|
|---|
| 23 | softfloat-source.txt Documentation for compiling SoftFloat.
|
|---|
| 24 | softfloat-history.txt History of major changes to SoftFloat.
|
|---|
| 25 | timesoftfloat.txt Documentation for using `timesoftfloat'.
|
|---|
| 26 |
|
|---|
| 27 | Other files in the package comprise the source code for SoftFloat.
|
|---|
| 28 |
|
|---|
| 29 | Please be aware that some work is involved in porting this software to other
|
|---|
| 30 | targets. It is not just a matter of getting `make' to complete without
|
|---|
| 31 | error messages. I would have written the code that way if I could, but
|
|---|
| 32 | there are fundamental differences between systems that I can't make go away.
|
|---|
| 33 | You should not attempt to compile SoftFloat without first reading both
|
|---|
| 34 | `softfloat.txt' and `softfloat-source.txt'.
|
|---|
| 35 |
|
|---|
| 36 | At the time of this writing, the most up-to-date information about
|
|---|
| 37 | SoftFloat and the latest release can be found at the Web page `http://
|
|---|
| 38 | HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'.
