* Add direct usage support for gl_DrawID (#8594)Copilot2025-10-03

In vulkan though, i should be able to use it directly, but because now i store it as a global variable, i cannot use the SV_DrawIndex semantic either. > > # Preferred Solution > I'd like to be able to use gl_DrawID like you how can use gl_BaseVertex and gl_BaseInstance. > </issue_description> > > <agent_instructions>You can just edit glsl.meta.slang and add a declaration for gl_DrawID in a similar way to gl_BaseVertex, and map it to SV_DrawIndex. > > Create a `//TEST:SIMPLE(filecheck=SPIRV): -target spirv` test case, and use filecheck to verify the output contains the correct SPIRV `DrawIndex` decoration.</agent_instructions> > > ## Comments on the Issue (you are @copilot in this section) > > <comments> > </comments> > </details> Fixes shader-slang/slang#8548 <!-- START COPILOT CODING AGENT TIPS --> --- ✨ Let Copilot coding agent [set things up for you](https://github.com/shader-slang/slang/issues/new?title=✨+Set+up+Copilot+instructions&body=Configure%20instructions%20for%20this%20repository%20as%20documented%20in%20%5BBest%20practices%20for%20Copilot%20coding%20agent%20in%20your%20repository%5D%28https://gh.io/copilot-coding-agent-tips%29%2E%0A%0A%3COnboard%20this%20repo%3E&assignees=copilot) — coding agent works faster and does higher quality work when set up for your repo. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>

* Simplify workflow when using NVAPI (#1556)Tim Foley2020-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, functionality is available as either a GLSL extension for Vulkan/SPIR-V, or through the NVAPI system for D3D. This situation creates complications because while GLSL extensions are generally all supported by the open-source glslang compiler (which we can bundle and ship), NVAPI operations are exposed through a specific header (`nvHLSLExtns.h`) that ships as part of the NVAPI SDK. When a user wants to explicitly use NVAPI-provided operations in their shader code, there are no major complications for Slang; the user sets up their include paths, `#include`s the relevant header, calls functions in it, and lets Slang deal with the details of compilation. The challenge for Slang arises when we want to provide a cross-platform interface in our standard library (e.g., the `RWByteAddressBuffer.InterlockedAddF32` method that was recently added) that uses either a GLSL extension (when compiling for Vulkan/SPIR-V) or an NVAPI (when compiling to DXBC or DXIL). In that case, the code *generated* by Slang now has a dependency on NVAPI, and we need to somehow emit a `#include` directive that pulls it in when invoking fxc or dxc. Because we do not (and seemingly cannot) bundle the NVAPI header with the compiler, we have to rely on ther user to have it available and to somehow communicate to Slang where it is. Exposing portable routines that sometimes use NVAPI currently creates two main challenges: 1. The user is forced to interact with the "prelude" mechanism in the compiler, which allows the programmer to define code in a given target language that gets prepended to the Slang-generated code. While the prelude mechanism is powerful, it is also hard for users to integrate into their workflow, and our experience so far is that users want something that Just Works. 2. If the user writes code that uses some of our abstract operations that layer on NVAPI *and* they also want to use NVAPI explicitly, they end up with two copies of the NVAPI header (one included by the Slang front-end, and another included by the downstream fxc/dxc compiler). This puts the user in the situation of (a) having to ensure that they set the defines like `NV_SHADER_EXTN_SLOT` consistently both when invoking Slang and when adding their prelude, and (b) even if they do make the definitions consistent, they run into the problem that fxc/dxc complain about overlapping register bindings on the two copies of the `g_NvidiaExt` global shader paraemter that the NVAPI header declares. This change attempts to resolve both issues by adding a lot of "do what I mean" logic to the compiler to try to ease things in the common case. In particular: 1. The user no longer needs to use the "prelude" mechanism when using NVAPI. The compiler now embeds a default prelude for HLSL output, which will `#include` the NVAPI header if and only if the generated code needs NVAPI access because of portable standard library routines that were used. 2. The user can mix-and-match explicit NVAPI use and stdlib functions that compile to use NVAPI. The register/space to be used by NVAPI when included via prelude is now set based on whatever the user set via the preprocessor so that it should automatically be consistent between both cases. Furthermore, the code we emit for the declaration of `g_NvidiaExt` when compiling explicit NVAPI use is set up to be conditional, so that it is skipped in the case where the prelude will pull in its own declaration of that parameter. The way all this is achieved involves a lot of moving pieces: * We now have an HLSL prelude, which mostly just serves to `#include "nvHLSLExtns.h"` in the case where NVAPI support is needed downstream. * Standard library operations that require NVAPI for their implementation on HLSL include a new `[__requiresNVAPI]` attribute. * The preprocessor has been extended so that after tokenizing an input file it looks up the NVAPI-relevant macros in the resulting environment, and if they are set it attached a modifier (`NVAPISlotModifier1) to the AST `ModuleDecl` that is based on their values. Logic is added to detect if multiple input files specify values for the macros in ways that conflict. * The semantic checking step is extended so that it detects the "magic" NVAPI declarations (the `g_NvidiaExt` paramter and the `NvShaderExtnStruct` type that it uses) and attaches a modifier to them so that they can be identified as such in later steps. * Parameter binding is extended to collect a list of the AST modifiers that reflect NVAPI binding, and to reserve the relevant register(s) so that ordinary user-defined parameters cannot conflict with them. * IR lowering translates the three new AST modifiers related to NVAPI over to IR equivalents. * IR linking is extended to make sure that it clones any `IRNVAPISlotDecoration`s attached to the input modules. The pass intentionally does not care where the modifiers came from; it just collects them all and leaves it to downstream code to sort out what they mean. * Emit logic is extended to have a notion of "prelude directives" which are preprocessor directives that should come *before* the prelude in the generated code, because they can impact the way that the prelude compiles. This is done so that we don't have to introduce ad hoc logic for each downstream compiler to set any relevant `-D` flags (e.g., both fxc and dxc would need to duplicate such logic for NVAPI support). * The HLSL source emitter is extended to track whether it emits any operations that require NVAPI support. * The HLSL source emitter is extended to emit prelude directives based on whether NVAPI is needed and, if it is, to also set the register and space that NVAPI should use based on what was stored in the decoration(s) on the IR module. * The HLSL source emitter is extended so that it detects global instructions that represent "magic" NVAPI constructs , and emit them as conditional definitions so that they are skipped when NVAPI is included via the prelude. * The handling of requires capabilities during emit logic was cleaned up a bit so that more logic is shared across targets, and also so that the same logic is used both when emitting a function declaration/definition and when emitting a call to an instrinsic function (which won't get declared/defined).

* Change how global-scope constants are handled (#1001)Tim Foley2019-07-17
| | | | | | | | | | | | | | | | | | | Before this change, global and function-scope `static const` declarations were represented as instructions of type `IRGlobalConstant`, which was represented similarly to an `IRGlobalVar`: with a "body" block of instructions that compute/return the initial value. This representation inhibited optimizations (because a reference to a global constant would not in general be replaced with a reference to its value), and also caused problems for resource type legalization because the logic for type legalization did not (and still does not) handle initializers on globals (so global *variables* that contain resource types are still unsupported). The change here is simple at the high level: we get rid of `IRGlobalConstant` and instead handle global-scope constants as "ordinary" instructions at the global scope. E.g., if we have a declaration like: static const int a[] = { ... } that will be represented in the IR as a `makeArray` instruction at the global scope, referencing other global-scope instructions that represent the values in the array. This simple choice addresses both of the main limitations. A `static const` variable of integer/float/whatever type is now represented as just a reference to the given IR value and thus enables all the same optimizations. When a `static const` variable uses a type with resources, the existing legalization logic (which can handle most of the "ordinary" instructions already) applies. Another secondary benefit of this approach is that the hacky `IREmitMode` enumeration is no longer needed to help us special-case source code emit for `static const` variables. Beyond just removing `IRGlobalConstant`, and updating the lowering logic to use the initializer direclty, the main change here is to the emit logic to make it properly handle "ordinary" instructions that might appear at global scope. One open issue with this change, that could be addressed in a follow-up change, is that "extern" global constants that need to be imported from another module (but which might not have a known value when the current module is compiled) aren't supported - we don't have a way to put a linkage decoration on them. A future change might re-introduce global constants as a distinct IR instruction type that just references the value as an operand (if it is available). We would then need to replace references to an IR constant with references to its value right after linking.
* Start exposing a new COM-lite API (#987)Tim Foley2019-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Start exposing a new COM-lite API This change is mostly about exposing a new API to the Slang compiler that allows more fine-grained control over the compilation flow. The basic concepts in the new API are: * An `IGlobalSession` is the granularity at which we load/parse the Slang stdlib, and therefore gives applications a way to amortize startup cost for the library across multiple compiles. This is a concept that might be able to go away in a future version of Slang. * An `ISession` owns all the code that gets loaded/compiled/generated. Any `import`ed modules are shared across everything in a session (we don't re-parse/-check the code when we see another `import` for the same module). Any generic- or interface-based code in the session can be specialized using types from the same session (but not necessarily across sessions). * An `IModule` is the unit of code loading and scoping. It doesn't expose any API in this change, but would be the right scope for looking up types or entry points by name. * An `IProgram` is a "linked" combination of modules and entry points from which code can be generated and reflection information queried. This change re-uses the existing reflection API types, rather than introduce a new API that duplicates that functionality. That will probably change in a future revision. There are two major pieces of functionality added here that aren't related to the new API: * We now have an API concept of "entry point groups" which are one or more entry points that are intended to be used together so that they need to have non-overlapping parameters. For now this is being used to handle "hit groups" and local root signatures for ray tracing, but I'm not sure this is a concept we will keep in the long run. * We have a very special-case (client-application-specific) flag that ascribes special meaning to the `shared` keyword, so that it can be attached to global parameters to indicate that they are actually to be part of the local root signature rather than the global one for DXR. None of the API design (including naming) here is finalized; the only reason to check in the changes at this point to avoid having a long-running branch that leads to merge pain. Clients should *not* try to depend on the new API just yet, since it is still a work in progress. * fixup: clang warning * fixup: try to detect clang C++11 support * fixup * fixup * fixup * fixup * fixup: review feedback
