D3D10 spec ( http://msdn.microsoft.com/en-us/library/windows/desktop/cc308050.aspx ) states that "Denorms are flushed to sign-preserved zero on input and output of any floating-point mathematical operation.".

So we might actually need to go back on this.

Otherwise the series looks good AFAICT. It's nice seing llvmpipe to support other ISAs!

So you gave commit access, or should I commit for you?
