(In reply to Robert Clausecker from comment #7)
Unfortunately, the test code is in no condition to submit,
and it isn't a simply matter to just fix it.  Fortunately,
Paul Zimmermann has independently confirmed that the patch
fixes rsqrtf(x) to be correctly rounded in round-to-nearest
for all input values (except, of course, exception cases
+-inf, NaN).  My main concern is that the code currently
in the tree is grabbed by other projects and then they
never update to the patched code.
