--- Comment #17 from Tom Stellard <tstellar at gmail.com> ---
Thanks for identifying the bad shaders, this saved me a lot of work.  I spotted
a bug in the "pc=8" shader:

6: TEX temp[1].x, temp[1].z___, 1D[3] SEM_WAIT SEM_ACQUIRE;

This instruction is wrong because TEX instructions can't swizzle their source
operands.  For 1D textures, the coordinate is always read from the x component.
