[Mesa-dev] [Bug 66806] [softpipe] glxgears floating point exception

--- Comment #1 from Roland Scheidegger <sroland at vmware.com> ---
I can't reproduce this here for some reason.
That said I think we should probably manipulate mxcsr a bit more, in particular
we should explicitly disable all exceptions (they are disabled by default but
app may enable them), since a shader can legitimately generate such an
exception regardless of denorms, and certainly getting that exception reported
is NOT the right answer.
(The other question is why there's an exception there in the first place for
simple glxgears shader. IIRC there were some problems with viewport being all
zero for the first draw call because some resize was missing or something like
that for some of the demos a while ago but I would expect that to produce zeros
not denorms.)
