[PATCH vkd3d] vkd3d-shader/hlsl: Add support for texture arrays. Replace sampler_dim with resource_dim.
New values for enum hlsl_sampler_dim are added in order to represent dimension types for textures that don't have their analog sampler, like Texture2DArray.
enum hlsl_sampler_dim is then renamed to enum hlsl_resource_dim to convey that it no longer represents just sampler types.
Parsing and initialization of Texture2DArray, Texture2DMS, Texture2DMSArray, and TextureCubeArray is added.
sampler_dim_count() is moved from hlsl.y to hlsl.h since it can be useful in other files, like in write_sm4_ld() in hlsl_sm4.c.
---
This patch is an alternative to 221390, which proposed to separate sampler_dim into sampler_dim and texture_dim. It will probably be resent after Matteo's batch is reviewed.

Sorry, it seems I have to add the sign-off before the "---" for it to be parsed.
I realized that the initialization of Texture2DMS, and Texture2DMSArray is not correct on this patch.
These textures require a "number of samples" parameter, as in Gio's branch.
Still, the rest of the patch may be worth considering.

New values for enum hlsl_sampler_dim are added in order to represent dimension types for textures that don't have their analog sampler, like Texture2DArray.
enum hlsl_sampler_dim is then renamed to enum hlsl_resource_dim to convey that it no longer represents just sampler types.
Parsing and initialization of Texture2DArray, Texture2DMS, Texture2DMSArray, and TextureCubeArray is added.
sampler_dim_count() is moved from hlsl.y to hlsl.h since it can be useful in other files, like in write_sm4_ld() in hlsl_sm4.c.
This patch is an alternative to 221390, which proposed to separate sampler_dim into sampler_dim and texture_dim. It will probably be resent after Matteo's batch is reviewed.

As one can tell from the commit message, this patch does at least two things at once, which is at least one too many ;-)
Personally I'm not sure that "sampler_dim" (or any of the associated names) need to be changed. I may be looking at things with GLSL-coloured glasses, but it seems to me there's no conceptual reason why a sampler couldn't have an array dimension; but rather HLSL just doesn't have a "sample2DArray" keyword.

Okay then. After some thought I have been more inclined to think that way too. More because the number of things that have to be changed is significant. At least this experiment helped me to understand on which parts of the codebase sampler_dim is used.

Yeah, fair enough. I'm mostly inclined to concur with "too soon to care".
Who knows, we might do something crazy like generalize HLSL_TYPE_TEXTURE to HLSL_TYPE_RESOURCE and store both buffers and textures the same way :-)
