-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'.
