* Add SPV_NV_bindless_texture support (#8534)Lujin Wang2025-09-26
| | | | | | | | | | | | | Treat DescriptorHandle as uint64_t instead of uint2. Implement target-specific SPIR-V emission with the bindless texture support. For OpImageTexelPointer, Image must have a type of OpTypePointer with Type OpTypeImage. Fix the issue by using [constref] in __subscript. Add a test coverage for various texture/sampler handle types. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
* [CBP] Pointer frontend changes + groupshared pointer support (#7848)ArielG-NV2025-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolves #7628 Resolves: #8197 Primary Goals: 1. Add `Access` to pointer 2. AddressSpace::GroupShared support for pointers (SPIR-V) 3. Add `__getAddress()` to replace `&` * `&` is not updated to `require(cpu)` since slangpy uses `&`. This means we must: (1) merge PR; (2) replace `&` with `__getAddress()`; (3) add `require(cpu)` to `&` Changes: * Added to `Ptr` the `Access` generic argument & logic (for `Access::Read`). * Moved the generic argument `AddressSpace` from `Ptr` to the end of the type. * Added pointer casting support between any `Ptr` as long as the `AddressSpace` is the same * Disallow globallycoherent T* and coherent T* * Disallow const T*, T const*, and const T* * Fixed .natvis display of `ConstantValue` `ValOperandNode` * Support generic resolution of type-casted integers * Added `VariablePointer` emitting for spirv + other minor logic needed for groupshared pointers Breaking Changes: * Anyone using the `AddressSpace` of `Ptr` will now have to account for the `Access` argument * we disallow various syntax paired with `Ptr` and `T*` --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
* Introduce CDataLayout & -fvk-use-c-layout (#8136)Julius Ikkala2025-08-21
| | | | | | | | | | | | | | | | Closes #8112. ~~The issue asks for a "C layout", but in this PR I use the term "CPU layout" because this naming was pre-existing in the codebase as `kCPULayoutRulesImpl_`. The primary purpose of this layout is to match CPU-side struct definitions with the shader side. I'm open to better naming suggestions, though.~~ Edit: switched back to using `CDataLayout` & `-fvk-use-c-layout`, as the CPU target depends on the object layout rules of existing CPU layout rules, but they're incompatible with actual shaders. So a new `kCLayoutRulesImpl_` was needed anyway. --------- Co-authored-by: Ellie Hermaszewska <ellieh@nvidia.com>
* Error if super-type capabilities are a super-set of sub-type (#7452)ArielG-NV2025-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes: #7410 Changes: 1. super-type capabilities must be a super-set of sub-type capabilities (and support the same shader stages/targets) * InheritanceDecl visits super-type to inherit it's capabilities; validate InheritanceDecl capabilities against sub-type * visit all container decl's with a default case * clean up functionDeclBase visitor * Simplify `diagnoseUndeclaredCapability` by moving logic into capability checking (more correct*) 3. added changed behavior to documentation 4. fixed some incorrect capabilities 5. **we do not** diagnose capability errors on interface requirement-to-implementation if both lack explicit capability requirements. This change is to work around a slangpy regression (test case for the failing situation is in `tests\language-feature\capability\capability-interface-extension-1.slang`), Note: maybe for slang-2026 we don't do this? 6. requirement & implementation must support the same shader stage/target. This was changed because otherwise we can have cases where `X` inherits from `Y`, but `Y` is only expected to be used in `glsl` whilst `X` is expected to be used in `hlsl | glsl` 7. removed `tests/language-feature/capability/capabilitySimplification3.slang` because it tests nothing special (redundant) Note: not using rebase due to separate branches depending on this PR --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

* Fix metallib-asm target parsing by adding missing comma (#7902)Jay Kwak2025-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix metallib-asm target parsing by adding missing comma The metallib-asm target was not being recognized from command line because of a syntax error in the target string definition in slang-type-text-util.cpp. A missing comma after the first "metallib-asm" string caused C++ string literal concatenation to create a malformed string.

* Remove some cruft/complexity from IR serialization (#7483)Theresa Foley2025-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove some cruft/complexity from IR serialization This is a very simple cleanup to unnecessary code paths and remove some flexibility that isn't actually needed, to hopefully simplify the task of more completely overhauling the approach to IR serialization in a later change. The concrete feature that gets removed here is a debug-only feature (which thus shouldn't be affecting any users of Slang) that was added long ago in the life of the compiler as we were working to truly separate the front- and back-ends. At the time there was a lot of code in the compiler back-end that still made use of AST-level data structures, and thus got in the way of our goal to support separate compilation and linking (such that final code generation can only depend on the IR, and not the AST). The option was used to cause the Slang IR to be serialized out and then read back in as part of compilation, to try and enforce that only the wanted constructs could pass through that bottleneck. The idea was only ever half implemented, however, because it made use of a secondary implementation path in IR serialization that supported serializing the "raw" source locations (which are heavily dependent on AST-level information, even down to the number of bytes in source files). This change removes the feature entirely, since it is no longer useful for its intended purpose, and its presence causes there to be entire second code path for source locations in IR serialization that would need to have test coverage if we wanted to be sure it kept working. In addition, our pre-existing infrastructure for module serialization had various options that have either stopped being useful, or were not really useful at the time they were introduced. For example: there are no places in the code today where we attempt to serialize out a module without including both the serialized AST and IR. If that was a feature that we ever supported, the relevant code got removed at some preceding point without breaking any of our tests or (seemingly) upsetting users. Similarly, the options being passed into writing of a serialized module included both a flag to control whether source locations should be serialized *and* a pointer to the `SourceManager` to use in that case... but it was only ever meaningful to set both, or neither. The option has been changed to just be the `SourceManager` pointer, and the name has been updated to reflect its very narrow intended use case. * format code * fixup * regenerate command line reference --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>

* Add command line option for separate debug info (#7178)jarcherNV2025-06-06
| | | | | | | | | | | | | * Add command line option for separate debug info Add command line arg -separate-debug-info which, if provided, produces both a .spv and a .dbg.spv file. The .dbg.spv file contains full debug info and the .spv file has all debug info stripped out. Also add a DebugBuildIdentifier instruction to store a unique hash in both the output files, so they can be more easily matched together. A matching API is provided to allow using the Slang API to retrieve a base and debug SPIRV as well as the debug build identifier string.

* Initial `dyn` keyword support & `-lang 2026` compiler option (#7172)ArielG-NV2025-05-22
| | | | | | | | | | | | | | | | | | | | fixes: [#7143](https://github.com/shader-slang/slang/issues/7143) fixes: [#7146](https://github.com/shader-slang/slang/issues/7146) Goal of PR: * This PR is part of the larger #7115 refactor to how dynamic dispatch works. * The first step is to add the `-std <std-revision>` flag. * The second step is to provide basic `dyn` keyword support in AST. This does not include `varDecl` support since most of these interactions require `some` keyword support. Future PR(s) goal: * Support `some` keyword in AST. With this we will also implement all varDecl interactions between `dyn` and `some`. * Add IR support for `some` and `dyn`. Breakdown of PR: * most of the logic is in `validateDyn.*`. This was done so that in the future when we implement more features we will have an easy time removing/adding restrictions to `dyn` interfaces. Breaking changes: * As per spec (https://github.com/shader-slang/spec/pull/14/files), any type conforming to a `dyn` interface errors if member list contains one of the following: opaque type, non copyable type, or unsized type. * Due to the breaking change, the test `tests\compute\dynamic-dispatch-bindless-texture.slang` is incorrect. This has been fixed.
* Support Vulkan memory model (#7057)Jay Kwak2025-05-16
| | | | | | | | | | | | | | | The user can explicitly use Vulkan memory model, or it will be automatically used when cooperative-matrix is used. When vulkan memory model is used, two keywords, "Coherent" and "Volatile", are not allowed. There are many differences regarding atomic and texture but this PR has changes limited to support `globallycoherent` keyword. When variables with `globallycoherent` is used with `OpLoad`, it will use additional options, `MakePointerAvailable|NonPrivatePointer`, that will provide the same effect. For `OpStore`, it will use `MakePointerVisible|NonPrivatePointer`.
* Fix broken -emit-spirv-via-glsl test option (#7091)sricker-nvidia2025-05-16
| | | | | | | | | | | | | | | | | | | | | | | | Fixes issue #6898 The -emit-spirv-via-glsl slang-test option has been broken for some amount of time. Tests that were using it were operating as if using -emit-spirv-directly, leading to many duplicated tests. After fixing the test option, there were an number of errors that appeared as a result. This change fixes the broken test option and the resulting test errors. Some of the test errors revealed some legitimate issues, such as: -The GLSL bitCount instrinsic only supports 32-bit integers and requires emulation for other bit widths. -Emitting GLSL 8-bit and 16-bit glsl integer types did not emit the proper extension requirements -Emitting GLSL and casting for 16-bit integers was missing a closing parenthesis. -Missing profile for GL_EXT_shader_explicit_arithmetic_types -Missing toType cases for UInt8/Int8 for the kIROp_BitCast case in tryEmitInstExprImpl.

When it is used, the HLSL for CoopVec will be emitted for the POC variant of DXC. When it is not used, the HLSL for CoopVec will be emitted for the DXC that officially supports the cooperative vector.
* Make Command Line Reference readthedocs compatible (#7048)aidanfnv2025-05-14
| | | | | | | | | | | | This change modifies the code that generates the Command Line Reference doc to output H2 headings in place of H1 headings, and H3 in place of existing H2, so that readthedocs will not treat the additional H1 headings as titles. This change also regenerates the Command Line Reference doc, as the current copy in the repo appears to be quite out-of-date. The existing copy is also encoded as UTF-16LE, whereas the other docs are all UTF-8. The regenerated doc is also UTF-8, and all I did to generate that was run slangc.exe -help-style markdown -h > docs\command-line-slangc-reference.md 2>&1 after building slangc on Windows. This change also adds GitHub actions workflows to check the contents of the doc, fail if a regenerated version needs to be checked in, and provide an option to regenerate it with a bot, all in a similar manner to User Guide TOC regeneration. The doc writer was producing different results from my local build until I changed how the writer sorts the shader stages. In the action, the order of pixel and fragment was reversed, despite the only difference from my local build being the OS. --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Added tests to be sure this works as intended with user API and with slangc command line * Change capability atom definitions and how Slang manages them to fix errors 1. most `glsl_spirv` version atoms have been removed from `.capdef`, instead we will translate `spirv` version atoms into `glsl_spirv` since there is no point in writing the same code twice in `.capdef` files to define `spirv` versions. 2. add spirv version, and hlsl sm version (and equivlent) capability dependencies 3. removed some stage requirments which were set on objects, keep the wrapper capabilities. I am keeping the wrapper capabilities since I am unaware on if there are stage limitations (spec says code in practice does not work). * check internal version instead of version profile (_spirv_1_5 vs. spirv_1_5) * remove unused OpCapability. adjust SPIRV version'ing again for glsl_spirv * apply workaround for glslang bug with rayquery usage * ensure capabilities targetted by a profile and added together by a user are valid * remove additions to `spirv_1_*` wrapper * spirv_* -> glsl_spirv fix * fix bug where incompatable profiles would cause invalid target caps * try to avoid joining invalid capabilities * fix the warning/error & printing * run through tests to fix capability system and test mistakes many mistakes were mesh shaders doing `-profile glsl_450+spirv_1_4`. This is not allowed for a few reasons 1. the test tooling does not handle arguments the same as `slangc` 2. glsl_450 core profile does not support mesh shaders, nor does spirv_1_4. sm_6_5 does work in this senario * set some sm_4_1 intrinsics to sm_4_0 * replace `GLSL_` defs with `glsl_` * swap the unsupported render-test syntax for working syntax * set d3d11/d3d12 profile defaults this is required since sm version changes compiled code & behavior * adjusted nvapi capabilities with atomics + d3d11 set to use sm_5_0 as per default * cleanup * address review * incorrect styling * change `bitscanForward` to work as intended on 32 bit targets --------- Co-authored-by: Yong He <yonghe@outlook.com>
