2024-06-28Implement HLSL resource bindings and default type `float4` to ↵ArielG-NV
`SubpassInput<T>` (#4462) * Add case to `emitVectorReshape` for `vector<>` type, `scalar` value 1. Add new case 2. Add test * fix warning * fix warning * Implement HLSL resource bindings and default type `float4` to `SubpassInput<T>` fixes: #4440 1. Removed GLSLInputAttachmentIndexLayout modifier and the somewhat 'hacky' binding model 'Input Attachment' previously relied upon. This was changed to work with the slang-type-layout rules system. This change allows Slang automatic bindings, HLSL bindings, GLSL bindings, and translation of GLSL to and from HLSL bindings to work. 2. Added default argument `float4` to SubpassInput<T>. 3. Merged glsl.meta and hlsl.meta SubpassInput logic. * fix InputAttachment attribute checks fix InputAttachment attribute checks for HLSL and GLSL syntax * remove unused var * validate attribute correctly Attributes do not have type information. We must check the type expression to validate attribute usage. * remove hacky validation type based validation before types are fully resolved is quite hacky and unstable to changes and wrapped types * fix warning * remove redundant `!= nullptr` * remove extra `!= nullptr` * fix some warnings/errors * subpass capability to limit to dxc & remove default values in some functions * revert logic to previous logic revert logic to return if we have a binding regardless of if a VarDecl is given the binding
2024-06-24Implementing `tbuffer` layout(s) (#4436)ArielG-NV
* Implementing `tbuffer` layouts. 1. Add to layout options 'TextureBuffer' layouts. 2. Add on to existing logic a way to allocate appropriate registers for TextureBufferType (this was made to work with parameter block logic). 3. Added asserts so objects missing a layout will gracefully crash This means `tbuffer` now works for hlsl,glsl,metal targets, spirv has yet to implement logic for `TextureBufferType`. * disable metal tests and fix emitting code a bit fixing the emitting code means metal compilation emits a useful error (help point users/developers to #4435) * fix warning

2024-04-03Refactor memory qualifier decorators to be a bit-flag set, resolves #3841 ↵ArielG-NV
(#3881) * Refactor memory qualifier decorators to be a bit-flag set. replace GloballyCoherent, ReadOnly, WriteOnly, Volatile, and Restrict memory modifiers and decorations with a bit flag set to more efficiently manage memory qualifiers. added `restrict` modifier to test to ensure the code works when dropping a `restrict` memory qualifier * Refine tests & add SSBO memory qualifer support add CHECK's to tests to ensure memory qualifiers emit as intended added tests and changed code to ensure memory qualifiers work on SSBO objects (SPIR-V & GLSL) * add memory qualifiers & fixes. Add to StructuredBuffer & ByteAddressBuffer `ReadOnly`/NonWritable qualifier. * Memory qualifiers must be decorated on a variable inst. Due to this the qualifier is added after `lowerStructuredBufferType` Fixed an error where ReadOnly->NonReadable & WriteOnly->NonWritable * Adjusted tests accordingly Added back the removed `globallycoherent` memory qualifier emit'ing code in hlsl-emit (was incorrectly removed). undo hlsl.meta changes cleanup
2024-04-03Implement 8.14-8.19 of OpenGL-GLSL specificationArielG-NV
The following PR implements 8.14-8.19 of the [OpenGL-GLSL specification](https://registry.khronos.org/OpenGL/specs/gl/GLSLangSpec.4.60.pdf). Fully implements all functions and built-in type's, resolves https://github.com/shader-slang/slang/issues/3692 for GLSL & SPRI-V targets. _Notes:_ Testing Tools: * Fragment shaders cannot test computational results. Only OpCodes are checked for proper emitting. Implementation Notes: * SubpassInput requires an unknown image format. * SubpassInput is disjoint from TextureType: __SubpassImpl (.slang) & SubpassInputType (Compiler) to reduce code generation required. * SubpassInput required an additional input layout modifier, input_attachment_index, this was added as a new parameter binding attribute. Since the following qualifiers can overlap with different resources (`layout(input_attachment_index = 0, binding = 0, set = 0)`) input_attachment_index is checked for overlapping resource bindings separately from other qualifiers with `LayoutResourceKind::InputAttachmentIndex`. * `GLSLInputAttachmentIndexLayoutModifier` was added to enforce function parameters only accepting `in` decorated variables. * `in` decorated variables needed to have emitting modified to allow directly emitting the variable into function calls if used as a parameter, normally Slang has a "global variable" shadow as a "global parameter" through a copy. This does not work and is solved using `GlobalVariableShadowingGlobalParameterDecoration` to build a relationship of "global variable" to "global parameter", we then resolve this relationship and replace "global variable" uses later in compile. * `AtomicCounterMemory` memory-constraint requires `OpCapability AtomicStorage`, `AtomicStorage` is invalid for Vulkan targets. glslang outputs for `barrier`, `memoryBarrier`, and `groupMemoryBarrier` `AtomicCounterMemory` as a memory constraint. This compiles as valid SPIR-V for Vulkan since `OpCapability AtomicStorage` is not declared. This behavior of glslang is undefined as per [3.31.Capability of the SPIR-V specification](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#_capability). We will omit `AtomicCounterMemory` from our barrier calls.

Fully implements all functions, built-in variables, & syntax; resolves #3560 for GLSL & SPIR-V Targets. notes of worth: * __rayPayloadFromLocation, __rayAttributeFromLocation, and __rayCallableFromLocation, were added as SPIR-V Intrinsics to refer to location's of raytracing objects in SPIR-V for when using GLSL syntax.

2023-06-13Fixes for Shader Execution Reordering on VK (#2929)Theresa Foley
* Fixes for Shader Execution Reordering on VK There are some mismatches between the way that hit objects are handled between the current NVAPI/HLSL and proposed GLSL extensions for shader execution reordering. These mismatches create complications for generating valid GLSL/SPIR-V code from input Slang. Many of the problems that apply to `HitObject` also apply to the existing `RayQuery<>` type used for "inline" ray tracing. In the case of `RayQuery<>` we have that for *both* HLSL and GLSL/SPIR-V: * A `RayQuery` (or `rayQueryEXT`) is an opaque handle to underlying mutable storage * The storage that backs a `RayQuery` is allocated as part of the "defualt constructor" for a local variable declared with type `RayQuery`. * The `RayQuery` API provides numerous operations that mutate the storage referred to by the opaque handle. The key difference between HLSL and GLSL/SPIR-V for the case of a `RayQuery` amounts to: * In HLSL, local variables of type `RayQuery` can be assigned to, and assignment has by-reference semantics. It is possible to create multiple aliased handles to the same underlying storage. * In GLSL/SPIR-V, local variables of type `rayQueryEXT` cannot be assigned to, returned from functions, etc. It is impossible to create multiple aliased handles to the same underlying storage. The case for `HitObject`s is signicantly *more* messy, because: * In NVAPI/HLSL a `HitObject` is effectively a "value type" in that it only exposes constructors, and there is no way to mutate the state of a `HitObject` other than by assignment to a variable of that type. It makes no semantic difference whether a `HitObject` directly stores the value(s), or if it is a handle, since there is no way to introduce aliasing of mutable state. Assignment of `HitObject`s semantically creates a copy. * In GLSL/SPIR-V, a `hitObjectNV` is, like a `rayQueryEXT`, a handle to underlying mutable state. These handles cannot be assigned, returned from functions, etc. There is no way to make a copy of a hit object. This change includes several changes to how *both* `RayQuery<>` and `HitObject` are implemented, with the intention of getting more cases to work correctly when compiling for GLSL/SPIR-V, and to set up a more clear mental model for the semantics we want to give to these types in Slang, and how those semantics can/should map to our targets. An overview of important changes: * Marked a few operations on `RayQuery` as `[mutating]` that realistically should have already been that way. * Marked the `HitObject` type as being non-copyable (an attribute we do not currently enforce), and marked the various GLSL operations that construct a hit object as having an `out` parameter of the `HitObject` type (even if they are nominally specified in GLSL as not writing to the correspondign parameter). * Added a distinct IR opcode (`allocateOpaqueHandle`) to represent the implicit allocation that happens when declaring a variable of type `HitObject` or `RayQuery`, and made the "implicit constructor" for those types map to the new op. This operation took a lot of tweaking to get emitting in a reasonable way, and I'm still not 100% sure that all of the emission-related logic for it is strictly required (or correct). * Added new IR instructions for `HitObject` and `RayQuery` types, and made the stdlib types map to those IR instructions. * Treat `HitObject` and `RayQuery` as resource types for the purpose of our existing pass that specializes calls to functions that have outputs of resource type * Added a new test case that includes a function that returns a `HitObject` as its result. * Many test cases saw slight changes in their output (especially around the relative ordering of declarations of `HitObject`s and `RayQuery`s with other instructions) * Remove debugging logic
