This is similar to what we do for textures where we program a number of channels matching the number of componentes actually read by the shader. Makes tests like dEQP-VK.image.load_store.with_format.2d.r32_uint drop from 18 instructions to 14 by emitting a single ldtmu instead of 4. From dEQP-VK.image.load_store.*: total instructions in shared programs: 12681 -> 12093 (-4.64%) instructions in affected programs: 4866 -> 4278 (-12.08%) helped: 256 HURT: 0 helped stats (abs) min: 1 max: 4 x̄: 2.30 x̃: 2 helped stats (rel) min: 4.76% max: 25.00% x̄: 12.35% x̃: 11.11% 95% mean confidence interval for instructions value: -2.40 -2.19 95% mean confidence interval for instructions %-change: -12.99% -11.71% Instructions are helped.
