I have to state that this doesn't look like a regression bug.

I was also telling nonsense on IRC. I can't reproduce this problem with HL2,
the only application I can trigger the bug is FEAR at the moment.

The source of the problem is this original D3D asm line:
rcp r0.w, t1.w

That's from a ps_2_0 program, it's converted to "RCP R0.w, A1.w".

According to stefand this has to do with aliasing of the Ax registers.
