I don't think renaming this makes sense. Currently the difference is whether they are modifiers that can be applied to a type, i.e. whether they're legal on typedefs. Interpolation modifiers aren't.

This logic needs tests, I think. It should be easy to add tests for nointerpolation.
Interpolation doesn't matter for outputs in sm4, but it does in sm6 and GLSL, so can you please add an equivalent of 3/4 for outputs?

Ok. I find 'nointerpolatoin' categorized as storage modifier confusing. It seems easier to call them all as 'modifiers', including ir_var field. Things like 'extern' and 'static' could remain as storage ones. But I don't care enough, I'll revert it.

The thing about it is that some of the flags go on the hlsl_type, and the rest go on hlsl_ir_var/hlsl_struct_field. We started separating the naming to make it clear which is which. Interpolation modifiers fall in the latter category.

Also, even when appropriate, changing an identifier is usually something that can stay in its own commit.

This looks longer and less readable than what you'd get by simply chaining the three cases with `else if`. I can live with it, though.

There will be at least two more entries there, so I don't think so.

Could you suggest a good reference about this feature? I can easily check compiler output, but looking at nointerpolation test, it requires more than that.

The GLSL spec at https://registry.khronos.org/OpenGL/specs/gl/GLSLangSpec.4.60.html#interpola... is fairly decent.
