<pre>The following instructions have issues with negative inline constants:
<span class="quote">> v_cubeid_f32
> v_cubema_f32
> v_cubesc_f32
> v_cubetc_f32
> v_div_fixup_f32
> v_div_fmas_f32

> v_mad_legacy_f32
> v_max3_f32
> v_med3_f32
> v_min3_f32
> v_mullit_f32</span >
Number of failing lit1 tests (-search=simple) = 4173.
I am almost sure that issue appears for other sub-targets as well, e.g. gfx8
Tested with r272673 (git # da10a460d7c98278561225fda90855b303675f35)</pre>
