* Add check for backtrace availability (#8329)Dario Mylonopoulos2025-09-06
| | | | | | | | | | | | | | The header execinfo.h and the related backtrace functionality is not available on all linux platforms. In particular it's missing on musl linux and on Android before API version 33. This causes compilation errors on those platforms. With this change, we first check if backtrace functionality is available by checking if we are using glibc or a compatible Android version. Tested on manylinux_2_28 with glibc 2.28 and musllinux_1_2 with musl 1.2, has not been tested on Android. Co-authored-by: Yong He <yonghe@outlook.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>

* 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>

* Fix API changes from separate debugging support (#7397)jarcherNV2025-06-12
| | | | | | Recent separate debugging support added two new functions which broke backwards compatibility. This change restores the old API and moves the new functions to an IComponentType2 interface which can be used if separate debug files are needed.
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Unify Debug Layer Control Logic and Add Disable Option for Debug Builds This PR refactors and unifies the debug layer control logic in slang-test. A new `-disable-debug-layers` option is introduced, allowing debug builds to skip enabling the validation (debug) layer. This is currently needed to ensure stability in the debug test suite. Previously, different toggles such as ENABLE_VALIDATION_LAYER, ENABLE_DEBUG_LAYER, and debugLayerEnabled were used inconsistently across different components of slang-test. This PR standardizes the logic by using a single variable, debugLayerEnabled, to control the enabling/disabling of the debug layer internally. Notes: By default, the debug/validation layer is enabled in debug builds and is not supported in release builds of slang-test.

* Remove support for ad hoc Slang IR compression (#6834)Theresa Foley2025-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove support for ad hoc Slang IR compression This change is part of a larger effort to clean up the approach to serialization in the Slang compiler. The overall goal is to simplify and streamline all of the serialization-related logic, so that we are left with code that is less "clever," and easier to understand for contributors to the codebase. Removing support for compression of serialized Slang IR has benefits that include: * Reduction in code complexity: consider things like the subtle way that the `FOURCC`s for compressed chunks were being computed from the uncompressed versions, and the mental overhead that goes into understanding that, for anybody who would dare to touch this code. * Reduction in testing burden: there have been, de facto, two very different code paths for serialization of the Slang IR, and it is not clear that the existing test corpus for Slang has sufficient coverage for both options. By having only a single code path, every test that performs any amount of IR serialization helps with test coverage of that one path. * Opportunity to explore alternatives. This is perhaps a reiteration of the first point, but once the code is stripped down to the simplest thing that could possibly work (I am not claiming it has reached that point yet), it becomes easier for contributors to understand, and it becomes more tractable for somebody to come along with an improved approach that performs better (in either compression ratio or performance) while still being maintainable. In my own local setup, I found that removing support for Slang IR compression led to the `slang-core-module-generated.h` file increasing in size from 46.1MB to 47.4MB. This increase in the `.h` file size for the core library binary only resulted in a release build of `slang.dll` increasing from 20.0MB to 20.2MB. Removing the ad hoc compression support has almost no impact on the size of actual binary Slang modules *so long* as the additional LZ4 compression step is being applied to them. * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
* Add -dump-module command to slangc (#6638)cheneym22025-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add -dump-module command to slangc The new -dump-module command to slangc will load and disassemble a slang module, similar to what would be seen by the -dump-ir command, except that -dump-ir tells slangc to print IR as it performs some compilation command. That is, -dump-ir requires some larger compilation task. -dump-module on the otherhand requires no additional goal and will simply load a module and print its IR to stdout independently from other compilation steps. Its intended purpose is to inspect .slang-module files on disk. It can also be used on .slang files which will be parsed and lowered if slang does not find an associated ".slang-module" version of the module on disk. The compilation API is extended with a new IModule::disassemble() method which retrieves the string representation of the dumped IR.

* Support SPIR-V deferred linking option (#6500)cheneym22025-03-05
| | | | | | | | | | | | | | | | | | | | | | | The new option "SkipDownstreamLinking" will defer final downstream IR linking to the user application. This option only has an effect if there are modules that were precompiled to the target IR using precompileForTarget(). Until now, the default behavior for SPIR-V was to use deferred linking, and the default behavior for DXIL was to use immediate/internal linking in Slang. This change only affects the SPIR-V behavior such that both deferred and non-deferred linking is supported based on the new option. To support the non-deferred option, Slang will internally call into SPIRV-Tools-link to reconstitute a complete SPIR-V shader program when necessary (due to modules having been precompiled to target IR). Otherwise, if SkipDownstreamLinking is enabled, the shader returned by e.g. getTargetCode() or getEntryPointCode() may have import linkage to the SPIR-V embedded in the constituent modules.

* Improve on spirv generation compile option (#5479)kaizhangNV2024-11-01
| | | | | | | | | | | | | | | | | | | CompilerOptionName::EmitSpirvViaGLSL and CompilerOptionName::EmitSpirvDirectly options are not mutually exclusive, but due to compatible reason, we cannot delete those options. Instead, this change makes the effort to create a new option name EmitSpirvMethod, and we will turn those two options into the new one internally. Also, we put a priority implicitly on those two options, where EmitSpirvDirectly always win if it's set. We have another location that can setup the same option, where is through SlangTargetFlags::SLANG_TARGET_FLAG_GENERATE_SPIRV_DIRECTLY. We should definitely deprecate this flag to avoid more confusing. But for the same compatible reason, we cannot do that in this PR. Again, we will encourage people to not use this flag, but using the CompilerOptionName instead. In this PR, we will also implicitly give CompilerOptionName higher priority, it means that as long as user setup the CompilerOptionName for emit spirv method, it always take higher priority for the final decision.
