-This C source fragment is part of the SoftFloat IEC/IEEE Floating-point\r
-Arithmetic Package, Release 2b.\r
-\r
-Written by John R. Hauser. This work was made possible in part by the\r
-International Computer Science Institute, located at Suite 600, 1947 Center\r
-Street, Berkeley, California 94704. Funding was partially provided by the\r
-National Science Foundation under grant MIP-9311980. The original version\r
-of this code was written as part of a project to build a fixed-point vector\r
-processor in collaboration with the University of California at Berkeley,\r
-overseen by Profs. Nelson Morgan and John Wawrzynek. More information\r
-is available through the Web page `http://www.cs.berkeley.edu/~jhauser/\r
-arithmetic/SoftFloat.html'.\r

-THIS SOFTWARE IS DISTRIBUTED AS IS, FOR FREE. Although reasonable effort has\r
-been made to avoid it, THIS SOFTWARE MAY CONTAIN FAULTS THAT WILL AT TIMES\r
-RESULT IN INCORRECT BEHAVIOR. USE OF THIS SOFTWARE IS RESTRICTED TO PERSONS\r
-AND ORGANIZATIONS WHO CAN AND WILL TAKE FULL RESPONSIBILITY FOR ALL LOSSES,\r
-COSTS, OR OTHER PROBLEMS THEY INCUR DUE TO THE SOFTWARE, AND WHO FURTHERMORE\r
-EFFECTIVELY INDEMNIFY JOHN HAUSER AND THE INTERNATIONAL COMPUTER SCIENCE\r
-INSTITUTE (possibly via similar legal warning) AGAINST ALL LOSSES, COSTS, OR\r
-OTHER PROBLEMS INCURRED BY THEIR CUSTOMERS AND CLIENTS DUE TO THE SOFTWARE.\r

-Derivative works are acceptable, even for commercial purposes, so long as\r
-(1) the source code for the derivative work includes prominent notice that\r
-the work is derivative, and (2) the source code includes prominent notice with\r
-these four paragraphs for those parts of this code that are retained.\r
