Comment= # 6 on bug 99019<= /a> from Marek Ol=C5=A1=C3=A1k 
The shader ends up in an infinite loop because of this:

...
        v_cmpx_le_f32_e32 vcc, 0, v0
        s_branch BB0_30
        s_cbranch_execnz BB0_30
; BB#29:
        exp null off, off, off, off done vm
        s_endpgm
BB0_30:                                 ; %endif110
...

s_branch shouldn't be there. It prevents killing the wave early and the loop
that follows is infinite, because it starts with EXEC=3D0.
