-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
