There are two motivations for this:
* First, the structure *almost* corresponds to D3D12_SHADER_INPUT_BIND_DESC, and if more elements were included, it could be used as-is for shader reflection.
There is the quirk that currently we return scan information based on the shader instructions, whereas d3dcompiler shader reflection expects to get it from the shader reflection data (i.e. the RDEF chunk), which is particularly relevant in the case that the RDEF chunk is stripped.
That said, even if we have to introduce an extra scan API to account for this difference, being able to reuse the same structure seems like a benefit.
In order to reuse this structure, we need to add the following elements:
- Register ID (added in part 1 of this series)
- Sample count (added in part 2 of this series)
- Flags or resource types to distinguish between typed, raw, and structured buffers. I have not decided which representation makes the most sense; opinions are welcome.
* Second, I think it makes sense to use this reflection information internally in spirv.c (and potentially other compiler backends) to declare resources in the target environment, instead of parsing DCL instructions. The idea here is that this allows backends to be more agnostic as to how resources are declared (or inferred) in the frontend, while avoiding the need to synthesize those DCL instructions in the frontend either [especially since epenthesizing instructions is more expensive than converting them to NOPs.]
In order to do that, we will need vkd3d_shader_scan_descriptor_info1 to cover everything that is currently covered by DCL instructions. This needs the same elements as above (register ID and sample count), but also:
- Structure stride (added in part 2 of this series)
- Constant buffer used width (added in part 2 of this series)
I don't currently have a proof-of-concept using these new elements. On the other hand, since it's just an extension of an existing API, I figured that seemed less critical.
This does conflict trivially with 280; I'm submitting it now since 280 is accepted, but due to Alexandre's vacation may not be committed soon, and since this is new API I'd rather get comments early anyway.
-- v2: vkd3d-shader: Get rid of the uav_ranges array. vkd3d-shader: Add register ID to struct vkd3d_shader_descriptor_info1. vkd3d-shader: Introduce struct vkd3d_shader_scan_descriptor_info1. vkd3d-shader: Centralize cleanup on error in scan_with_parser(). vkd3d-shader: Factor more code into vkd3d_shader_scan_get_uav_descriptor_info().

I can see the value in avoiding exposing the API unless necessary. It'd be an awkward and nontrivial bit of extra work to make this internal, though, given how the descriptor info is currently accessed by vkd3d_shader_parser_compile().
Maybe not trivial, but it doesn't seem that hard? In particular, I imagine we can essentially just pass the new structure as optional parameter to scan_with_parser() and use it instead of "local_descriptor_info1" if present.
Okay, it's significantly easier than I thought; I don't know what kind of tunnel vision I had that was preventing me from doing it cleanly.
I've pushed a new version that does this. It also keeps all the current naming, which makes it look like it's still an exported structure. I think this is fine, because I'm still pretty confident we'll want to export this eventually, but I can change it if requested.

The vkd3d_malloc() call is safe because sizeof(*info->descriptors) <= sizeof(*info1->descriptors), but I don't think it's setting a great example; we'd generally want to use vkd3d_calloc().
