Hmm, I remember that I had to fiddle with the long double values to make them work on x86. Not all random bitstrings are valid x86 long doubles. This test isn't the most portable, since I generate values by creating random longs and stitching them together. I'll have to look up the format for ia64 long double, but we may end up going back and forth a couple of times to get it right. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17140
