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
