2025-01-07 Check whether array element is fully specialized (#6000)kaizhangNV
* Check whether array element is fully specialized close #5776 When we start specialize a "specialize" IR, we should make sure all the elements are fully specialized, but we miss checking the elements of an array. This change will check the it. * add test * add all wrapper types into the check * add utility function to check if the type is wrapper type --------- Co-authored-by: zhangkai <zhangkai@zhangkais-MacBook-Pro.local> Co-authored-by: Yong He <yonghe@outlook.com>
2025-01-07Use disassemble API from SPIRV-Tools (#6001)Jay Kwak
* Use disassemble API from SPIRV-Tools This commit uses C API version of SPIRV disassemble function rather than calling spirv-dis.exe. This allows us to use a correct version of SPIRV disassble function that Slangc.exe is using. The implementation is mostly copied from external/spirv-tools/tools/dis/dis.cpp, which is a source file for building spirv-dis.exe. This commit also includes a fix for a bug in RPC communication to `test-server`. When an RPC connection to `test-server.exe` is reused and the second test abruptly fails due to a compile error or SPIRV validation error, the output from the first test run was incorrectly reused as the output for the second test. This commit resets the RPC result before waiting for the response so that even when the RPC connection is erratically disconnected, the result from the previous run will not be reused incorrectly. Some of the tests appear to be relying on this type of behavior. By using an option, `-skip-spirv-validation`, the RPC connection will continue without an interruption.

2025-01-02Correct IR generation for no-diff pointer type (#5976)kaizhangNV
* Correct IR generation for no-diff pointer type Close #5805 There is an issue on checking whether a pointer type parameter is no_diff, we should first check whether this parameter is an Attribute type first, then check the data type. In the back-propagate pass, for the pointer type parameter, we should load this parameter to a temp variable, then pass it to the primal function call. Otherwise, the temp variable will no be initialized, which will cause the following calculation wrong.

2024-12-18Fix the parser issue for not recognize Generic<T>[N] (#5912)kaizhangNV
Close #5911. In this issue, if we define the generic in source file 1, and import it into source file 2, then when parsing the reference of that generic in source file 2, we will not parse the generic directly, instead we have a logic to speculate it as generics first with a fake diagnostic sink, and if there is no error report, we will consider it as a actual generic and will parse it again. In this logic, we will also disambiguate the expression based on the following token, but we didn't consider the token '[', so we will finally not treat the expression as generic. The fix is just simply add '[' here. Co-authored-by: Yong He <yonghe@outlook.com>

* Back out "Update SPIRV submodules (#5815)" This backs out commit e50aac13e2c161d672b137a62f6d66820d0f9ff1. * Use upstream spirv-tools * Fix bump-glslang.sh for newer versions of spirv-tools * Use upstream glslang * Add --do-fetch option to bump glslang * Bump glslang and friends Supersedes https://github.com/shader-slang/slang/pull/5815 * Regenerate glslang and spirv-tools outputs * Fixes to slang-glslang * Correct spirv intrinsic for OpImageSampleFootprintNV Note that this currently fails validation with the following error: ``` error: line 145: Result <id> from OpSampledImage instruction must not appear as operand for OpImageSampleFootprintNV, since it is not specified as taking an OpTypeSampledImage. Found result <id> '55[%sampledImage]' as an operand of <id> '56[%resultVal]'. %sampledImage = OpSampledImage %54 %51 %40 ``` This seems to be in error as the spec for *SPV_NV_shader_image_footprint* states that "Sampled Image must be an object whose type is OpTypeSampledImage" https://refined-github-html-preview.kidonng.workers.dev/KhronosGroup/SPIRV-Registry/raw/refs/heads/main/extensions/NV/SPV_NV_shader_image_footprint.html glslang also seems to fail with the same validation error * Fix spv storage class test
