PROMINENT NOTICE: THIS IS A DERIVATIVE WORK OF THE ORIGINAL SOFTFLOAT CODE
|
|
CHANGES:
|
|
Comment out FLOAT128
|
|
Removed all signed char => char
|
|
Inserted this file is a namespace
|
|
Added variable to control the sending of real system traps
|
|
Protect this header by a #define
|
|
pack the fields of floatx80, just in case (should be useless)

This C header file is part of the SoftFloat IEC/IEEE Floating-point Arithmetic

Package, Release 2b.

Written by John R. Hauser. This work was made possible in part by the
|
|
International Computer Science Institute, located at Suite 600, 1947 Center
|
|
Street, Berkeley, California 94704. Funding was partially provided by the
|
|
National Science Foundation under grant MIP-9311980. The original version
|
|
of this code was written as part of a project to build a fixed-point vector
|
|
processor in collaboration with the University of California at Berkeley,
|
|
overseen by Profs. Nelson Morgan and John Wawrzynek. More information
|
|
is available through the Web page `http://www.cs.berkeley.edu/~jhauser/
|
|
arithmetic/SoftFloat.html'.

been made to avoid it, THIS SOFTWARE MAY CONTAIN FAULTS THAT WILL AT TIMES

RESULT IN INCORRECT BEHAVIOR. USE OF THIS SOFTWARE IS RESTRICTED TO PERSONS
