2021-06-25Fixes related to combined texture/sampler types (#1894)Theresa Foley
* Fixes related to combined texture/sampler types Work on #1891 Our intention has always been to support combined texture/sampler types in Slang, both targets like OpenGL where that is the only option available and for targets like Vulkan where it can be beneficial to performance. Because Slang's current users mostly focus on D3D12+Vulkan codebases, they strongly prefer separate textures and samplers, and the relevant support code in Slang has "bit-rotted" over many releases until the functionality that was there isn't useful any more. This change significantly overhauls the implementation of combined texture/sampler types and adds a test that uses them in the hopes of avoiding future regressions. The new combined texture/sampler types use the prefix `Sampler`, so where there is an existing standalone `Texture2D` type the equivalent combined texture/sampler type will be `Sampler2D`. The intention is that this naming mirrors the GLSL conventions (where the type is `sampler2d`) while following HLSL naming precedent (to the extent it exists). The operations available on a `Sampler2D` are intended to be those that are available on a `Texture2D`, and it is just that in cases where the `Texture2D` operation would take a separate sampler argument: Texture2D t = ...; SamplerState s = ...; float4 result = t.Sample(s, uv); the equivalent `Sampler2D` operation just elides that argument: Sampler2D s = ...; float4 result = s.Sample(uv); In terms of implementation, there are a lot of subtle details here: * I've tried to use the same metaprogramming logic that generates all the stdlib declarations for `Texture*` to also generate `Sampler*` in the hopes that this helps keep them in sync. * The big catch to the above is that it means that for certain operations the indidces of parameters depend on whether or not an explicit sampler parameter is used. Rather than try to tweak the indices in the stdlib generation logic (which is already complicated) I went and added Yet Another Hack to the logic that handles intrinsic definition strings. Basically, the special-case handling of `$p` has been modified so that it *also* applies a negative offset to future parameter references in the same intrinsic string. * Trying to actually bring this up in our test framework revealed that the "flat" reflection API was seemingly not reflecting combined texture/sampler types correctly at all (it was reflecting them as just plain textures). Other than that issue, the Vulkan path seems to work fine with combined texture/samplers. * I also had to add logic to the `TEST_INPUT` parsing to re-introduce handling of the combined types (that was something I consciously left out to reduce the amount of code in the earlier refactor there). Luckily, the architecture is such that a combined texture/sampler can leverage most of the existing logic for the separate cases. * fixup: reveiw feedback

2021-06-08Various fixes to CUDA backend. (#1877)Yong He
- Fix emitting `StructuredBuffer<ISomething>::Load`, which triggers emitting for `IROp_WrapExistential` that is previously unhandled. - Fix cuda layout around vectors, they should be aligned to 1,2,4,8,16 bytes instead of just using element type's alignment. That means `float4` has alignment of 16 instead of 4. - Fix `SLANG_CUDA_HANDLE_ERROR` macro definition. - Fix navis sometimes fail to find `Slang::kIROp_*` enum values when debugging external projects.
