| This is starting to smell like a compiler bug in fp correctness...but
| I'm out of time to diagnose it further.
In case anyone missed it, the i386 ATF test on b5 failed the exact same way
(same values) as my Xen DomU i386 test. But that was as expected I think.
Since this has now devolved to a discussion of how i386 FP works, and
how the compiler generates code to use it, I'm out of this discussion from
here on (I will send a message on port-i386 and tech-userlevel to see if
someone with i386 FP knowledge can work out who/what is at fault here.)
Unless someone finds a fix, or at least finds the source of the problem,
and files a PR, I will return this test to "succeeding" status (by "hiding"
the problem, as Joerg put it). This test is not the place to diagnose either
compiler issues, or i386 floating point issues. If we need a test for those,
please add one - elsewhere.
