[PATCH v3 0/3] MR536: vkd3d-shader/ir: Revert "Do not merge signature elements which have different interpolation modes."
-- v3: vkd3d-shader/ir: Set merged signature element interpolation mode only from used elements. tests: Test an interpolated PS input where component x is unused. vkd3d-shader/ir: Revert "Do not merge signature elements which have different interpolation modes."
