Update SPIRV-Tools and fix new validation errors. (#6511)

2025-03-06T22:26:34+00:00

* Update SPIRV-Tools and fix new validation errors. * Implement pointers for glsl target. * Reworked packStorage/unpackStorage code gen to operate on pointers rather than values.

Add validation for destination of atomic operations (#6093)

2025-01-22T17:10:35+00:00

* Reimplement the GLSL atomic* functions in terms of __intrinsic_op Many of these functions map directly to atomic IR instructions. The functions taking atomic_uint are left as they are. This helps to address #5989, since the destination pointer type validation can then be written only for the atomic IR instructions. * Add validation for atomic operations Diagnose an error if the destination of the atomic operation is not appropriate, where appropriate means it's either: - 'groupshared' - from a device buffer This closes #5989. * Add tests for GLSL atomics destination validation Attempting to use the GLSL atomic functions on destinations that are neither groupshared nor from a device buffer should fail with the following error: error 41403: cannot perform atomic operation because destination is neither groupshared nor from a device buffer. * Validate atomic operations after address space specialization Address space specialization for SPIR-V is not done as part of `linkAndOptimizeIR`, as it is for e.g. Metal, so opt out and add a separate call for SPIR-V. * Allow unchecked in/inout parameters for non-SPIRV targets * Clean up callees left without uses during address space specialziation * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He

Implement glsl atomic's [non image or memory scope] with optional extension(s); resolves #3587 for GLSL & SPIR-V targets (#3755)

2024-03-13T19:03:16+00:00

The following commit implements atomic operations & types associated with OpenGL 4.6, GL_EXT_vulkan_glsl_relaxed, GLSL_EXT_shader_atomic_float, GLSL_EXT_shader_atomic_float2, for GLSL & SPIR-V targets. Fully implements all functions, and built-in type's, resolves https://github.com/shader-slang/slang/issues/3560 for GLSL & SPRI-V targets. [Atomic extensions for GLSL can be found here](https://github.com/KhronosGroup/GLSL/tree/main) Notes of worth: * atomic_uint is well defined in GLSL->OpenGL, although was removed in GLSL->VK unless a compiler extension is supported (GL_EXT_vulkan_glsl_relaxed). This support entails transforming all atomic_uint operations and references into a storage buffer. SPIR-V has AtomicCounter+AtomicStorage (atomic_uint parallel) but does not implement these capabilities for SPIR-V->VK in any scenario. Due to the case we transform atomic_uint ourselves (GLSL_Syntax->Slang_IR) to accommodate transforming atomic_uint into valid syntax. * GLSL_EXT_shader_atomic_float2 (all float16_t & some float/double operations) support is minimal and worth watching out for if enabling the tests.
