* Support a storage class, NodePayloadAMDX, for SPIRV work-graphs (#6052)Jay Kwak2025-01-09
| | | | | | | | | | | | | | | In order to unblock experiments with SPIRV work-graphs, Slang needs to support the storage class, `NodePayloadAMDX`. Note that this commit is only to support a storage class, `NodePayloadAMDX`. There are many parts required for work-graphs hasn't been implemented yet. The implementation of `DispatchNodeInputRecord` is not required, but it is implemented mostly for a testing purpose. Closes #6049 Co-authored-by: Yong He <yonghe@outlook.com>
* Use disassemble API from SPIRV-Tools (#6001)Jay Kwak2025-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* Emit OpExecutionMode SpacingEqual for Domain stage (#5696)Jay Kwak2024-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Domain stage should emit one more `OpExecutionMode` with `SpacingEqual`, similary to how Hull stage does. Currently Hull stage emits four OpExecutionMode as following: OpExecutionMode %hullMain SpacingEqual OpExecutionMode %hullMain OutputVertices 4 OpExecutionMode %hullMain VertexOrderCw OpExecutionMode %hullMain Quads And Domain stage emits only one OpExecutionMode: OpExecutionMode %domainMain Quads This commit adds the following instruction for Domain stage: OpExecutionMode %domainMain SpacingEqual It is because the Vulkan Validation Layer prints error when the Domain shader didn't have `OpeExecutionMode SpacingEqual`. `SpacingEqual` corresponds to an attribute, `[partitioning("integer")]`, given to the Hull stage. Although Domain stage is not marked with same attribute, it is assumed to use the same value used for matching Hull Stage. The error message from VVL is following: ``` vkCreateShadersEXT(): pCreateInfos[2].stage is VK_SHADER_STAGE_TESSELLATION_EVALUATION_BIT, but spacing is not specified. The Vulkan spec states: If codeType is VK_SHADER_CODE_TYPE_SPIRV_EXT, and stage is VK_SHADER_STAGE_TESSELLATION_EVALUATION_BIT, pCode must contain an OpExecutionMode instruction specifying the spacing of segments on the edges of tessellated primitives (https://vulkan.lunarg.com/doc/view/1.3.283.0/windows/1.3-extensions/vkspec.html#VUID-VkShaderCreateInfoEXT-codeType-08874) ``` Co-authored-by: Ellie Hermaszewska <ellieh@nvidia.com>

* Precompiled SPIR-V import support (#5048)cheneym22024-10-29
| | | | | | | | | | | | | | | | | | | | * Precompiled SPIR-V import support Adds appropriate linkage and function declaration syntax for SPIR-V functions that are declared, to be imported from another SPIR-V module. Unlike DXIL, stripping the Slang IR for a function down to a declaration requires retaining a block of parameters, as the function declaration must be emitted to SPIR-V with the same parameters as a definition. Because that thwarts the logic in Slang to tell the difference between a declaration and definition, and explicit decoration is introduced to explicitly mark functions which need to be treated as declarations during emit phase.
