Anyone interested in working on FP emulation (or checking the shortcuts DEC made when then designed the Alpha) might like to check out <http://www.netlib.org/fp/ucbtest.tar.gz>: UCBTEST is a suite of programs for testing certain difficult cases of IEEE 754 floating-point arithmetic. Some of the difficult test cases are obtained from number-theoretic algorithms developed by Turing Award winner Prof. W. Kahan, Department of Electrical Engineering and Computer Science, University of California, Berkeley, as part of ongoing research into test methods for computer arithmetic.
