Re: [Qemu-devel] [Bug 645662] x87 fpu emulation not accurate enough

[KONRAD Frederic]

Hi,

I have the same problem here with some of our math testsuites.
It's about some precision issue with trigonometric tests.

I didn't had time to figure out what happen neither what is
really going wrong. eg: trigonometric function or?

A quick workaround is to use KVM when possible.
