[PATCH v4 0/5] MR358: vkd3d-shader/hlsl: Parse 'centroid' and 'noperspective' modifiers.
Signed-off-by: Nikolay Sivov nsivov@codeweavers.com
-- v4: vkd3d-shader/tpf: Output interpolation modifiers for input declarations. vkd3d-shader/hlsl: Propagate structure fields modifiers when copying shader inputs. vkd3d-shader/hlsl: Allow interpolation modifiers on structure fields. vkd3d-shader/hlsl: Parse 'centroid' and 'noperspective' modifiers. tests: Add a test for interpolation modifiers specified on structure fields.

This is... technically addressed, but I'd say we should, along the same lines, call these HLSL_STORAGE_CENTROID and HLSL_STORAGE_NOPERSPECTIVE. HLSL_MODIFIER_* is only for those valid on typedefs.
Changed that, thanks.

Or maybe they are not. The order of precedence is 'nointerpolation' -> 'sample' -> 'centroid' or 'noperspective'. Conflicts are tested only at the same level - on fields or variables.
Added some more tests.
