Don't crash when precompiling twice (#6576)

2025-03-11T18:12:33+00:00

Abort precompileForTarget if it's already done. Fixes #6516

Fix precompiledTargetModule tests (#6455)

2025-02-27T02:20:29+00:00

* Fix precompiledTargetModule tests Add SPIRV-Tool linker support to gfx unit tests and use the linker in precompileModule tests that use precompiled modules to reconstitute SPIRV shaders that were modularly compiled. Fix a Slang reference count bug in the precompile service. * Use sm_6_6 New DXC requires higher version for linkability. * Rename helper function, pass by reference * Link through slang-glslang * Add missing files * Fix metal * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He

Fix spirv codegen for pointer to empty structs. (#5355)

Fix precompiled glsl modules (#5230)

2024-10-09T18:42:13+00:00

When precompiling modules defined with glsl, it's necessary to link in the glsl definition module. Reuse the public fillRequirements declaration

Add interfaces for retrieving separate linkable downstream binaries (#5128)

2024-10-04T14:20:57+00:00

* Implement separate downstream library interface Create a new com interface to house the methods for precompiling slang modules to target code. Add methods to count dependent modules and scrape them for downstream target binaries such that the downstream target binaries are linkabe outside of slang, e.g. via spirv-link or dxc. Fixes #5147 * Rename to _Experimental Clearly identify this as an interface subject to change.

Initial -embed-spirv support (#4974)

2024-09-05T18:59:28+00:00

* Initial -embed-spirv support Add support for SPIR-V precompilation using the framework established for DXIL. Work on #4883 * SLANG_UNUSED * Add linkage attributes to exported spirv functions * Combine DXIL and SPIRV paths * Whitespace fix * Merge remaining precompiled spirv/dxil paths * Change inst accessors to return codegentarget * Add unit test for precompiled spirv --------- Co-authored-by: Yong He

Support mixture of precompiled and non-precompiled modules (#4860)

2024-08-30T06:23:26+00:00

* Support mixture of precompiled and non-precompiled modules This changes the implementation of precompile DXIL modules to accept combinations of modules with precompiled DXIL, ones without, and ones with a mixture of precompiled DXIL and Slang IR. During precompilation, module IR is analyzed to find public functions which appear to be capable of being compiled as HLSL, and those functions are given a HLSLExport decoration, ensuring they are emitted as HLSL and preserved in the precompiled DXIL blob. The IR for those functions is then tagged with a new decoration AvailableInDXIL, which marks that their implementation is present in the embedded DXIL blob. The DXIL blob is attached to the IR as before, inside a EmbeddedDXIL BlobLit instruction. The logic that determines whether or not functions should be precompiled to DXIL is a placeholder at this point, returning true always. A subsequent change will add selection criteria. During module linking, the full module IR is available, as well as the optional EmbeddedDXIL blob. The IR for functions implemented by the blob are tagged with AvailableInDXIL in the module IR. After linking the IR for all modules to program level IR, the IR for the functions marked AvailableInDXIL are deleted from the linked IR, prior to emitting HLSL and compiling linking the result. This change also changes the point of time when the module IR is checked for EmbeddedDXIL blobs. Instead of happening at load time as before, it happens during immediately before final linking, meaning that the blob does not need to be independently stored with the module separate from the IR as was done previously. Work on #4792 * Clean up debug prints * Call isSimpleHLSLDataType stub * Address feedback on precompiled dxil support Allow for IR filtering both before and after linking. Only mark AvailableInDXIL those functions which pass both filtering stages. Functions are corrlated using mangled function names. Rather than delete functions entirely when linking with libraries that include precompiled DXIL, instead convert the IR function definitions to declarations by gutting them, removing child blocks. * Use artifact metadata and name list instead of linkedir hack * Use String instead of UnownedStringSlice * Update tests * Renaming * Minor edits * Don't fully remove functions post-link * Unexport before collecting metadata

Make precompileForTargets work with Slang API (#4845)

2024-08-15T16:36:41+00:00

* Make precompileForTargets work with Slang API precompileForTargets, renamed to precompileForTarget, does not need an EndToEndCompileRequest and some objects created from it are not necessary either. Take only a target enum and a diagnostic blob as input and handle everything else internally, such as creating the TargetReq with chosen profile. Fixes #4790 * Update slang-module.cpp * Update slang-module.cpp
