[PATCH v3 0/7] MR66: vkd3d-shader/hlsl: Broaden resources support v2 (PART 1).
First part of v2 of !27, which aims to: * Allow allocation of variables of complex types that contain both numerics and objects across multiple register sets (regsets). * Support the tex2D and tex3D intrinsics, inferring generic samplers dimension from usage, writing sampler declarations, and writing sample instructions. * Support for arrays of resources for both SM1 and SM4 (not to be confused with the resource-arrays of SM 5.1, which can have non-constant indexes). * Support for resources declared within structs. * Support for synthetic combined samplers for SM1 and synthetic separated samplers for SM4, considering that they can be arrays or members of structs. * Imitate the way the native compiler assigns the register indexes of the resources on allocation, which proved to be the most difficult thing. * Support for object components within complex input parameters. * Small fixes to corner cases. This part consists on parsing the `tex2D()` and `tex3D()` intrinsics and beginning to support the allocation of variables across multiple regsets. The whole series, is on my [master6](https://gitlab.winehq.org/fcasas/vkd3d/-/commits/master6) branch. -- v3: vkd3d-shader/hlsl: Allocate register reservations in a separate pass. vkd3d-shader/hlsl: Allocate objects according to register set. vkd3d-shader/hlsl: Keep an hlsl_reg for each register set in hlsl_ir_var. vkd3d-shader/hlsl: Store the type's register size for each register set. vkd3d-shader/hlsl: Parse the tex3D() intrinsic. vkd3d-shader/hlsl: Parse the tex2D() intrinsic. vkd3d-shader/hlsl: Avoid segfault on missing sampler. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/66

For instance, in the following shader: https://shader-playground.timjones.io/fc9cdeee0e000008281a7d3f1c7d94b9 even if only one texture and one sampler are used, they bindings are `t5` and `s2` respectively.

Rebased, I also applied all requested changes except changing the names of the object regsets, namely `HLSL_REGSET_S`, `HLSL_REGSET_T`, and `HLSL_REGSET_U`, which is a thing I would like to bikeshed a little more. I think that these values of `enum hlsl_regset` should indeed map to a single type of register, as in the function `hlsl_regset_name()`, save for `HLSL_REGSET_NUMERIC`. I am starting to see we are converging to define a clear point in `hlsl_emit_bytecode()` where we start performing backend-specific operations over the IR, which is after the last call to `compute_liveness()` (well, it is still pending to move the `transform_deref_paths_into_offsets` pass forward for this to hold 100% true, but lets assume that). This makes sense to me, since lowering passes and register allocation, which happen after that point, **have** to contain backend-specific details. While `reg_size` is backend-specific, it is only **precomputed** at the time the type it is generated, but not used after this backend-specific point, same for the introduced `regsets` in general. So, I don't see much reason to have them represent another level of indirection using values such as `HLSL_REGSET_RESOURCES` since they are used pass this point of backend-specific-ness. Also, with the current scheme, it is fairly easy to add new regsets or object types to a different one if required by the backend. It is just a matter of adding a new entry to `enum hlsl_regset`, and modifying `hlsl_type_get_regset()` and `hlsl_regset_name()`. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/66#note_22414

I don't know how the others feel about that, but in general my philosophy is that you shouldn't mix refactoring and changing the behavior in a single commit.

I can think of a use case: For shader model 5, object components have to be promoted to their own variables before writing the RDEF. If we have an array of Textures and the first texture is used, we would have both the array and the texture as variables colliding in those fields, even if the array is not written to the RDEF. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/66#note_22486
