2025-02-06Don't overwrite existing module decl scopes when parsing new source files ↵Anders Leino
(#6292) When a module consists of multiple source files, the module scope gets over-written for each source file that's parsed into the module. The result is that if you do something like the following, where source1.slang contains an import statement, then the imported module will get imported into the module scope corresponding to source2.slang, but won't be found from the scope of source1.slang. slangc source1.slang source2.slang # 1 module from 2 source files This patch fixes this problem by not over-writing existing container decl scope when parsing new source files into the container. This closes $6221.

2025-02-05Enable D3D12 experimental feature to use coopvec (#6290)Jay Kwak
This commit enables "D3D12-experimenta-feature" in render-test. This is required to use CoopVec feature with dxcompiler.dll. But it is enabled only when "-dx12-experimental" is used, because it appears that DX12 becomes unstable when the experimental feature is enabled, which causes bunch of tests randomly failing.

2025-02-05Feature/initialize list side branch (#6058)kaizhangNV
* SP004: implement initialize list translation to ctor - We synthesize a member-wise constructor for each struct follow the rules described in SP004. - Add logic to translate the initialize list to constructor invoke - Add cuda-host decoration for the synthesized constructor - Remove the default constructor when we have a valid member init constructor - Disable -zero-initialize option, will re-implement it in followup (#6109). - Fix the overload lookup issue When creating invoke expression for ctor, we need to call ResolveInvoke() to find us the best candidates, however the existing lookup logic could find us the base constructor for child struct, we should eliminate this case by providing the LookupOptions::IgnoreInheritance to lookup, this requires us to create a subcontext on SemanticsVisitor to indicate that we only want to use this option on looking the constructor. - Do not implicit initialize a struct that doesn't have explicit default constructor.

2025-02-05Fix autodiff issue for vector<T, N> (#6275)kaizhangNV
* Fix autodiff issue for vector<T, N> Close #6154 We didn't implement correctly for vector<T, N> regarding the differentiablity. As we check differentiable before specialization, however according to the definition of vector, it has to be specialized to IFloat to know it's conformed to IDifferential type. Therefore for parameter type vector<T, N> will become no_diff. Therefore, we change the implementation a to make it explicit conform to IDifferential type. * fix typo

2025-01-31Update Slang-RHI and enable any debug layers up-front (#6226)Anders Leino
* Update Slang-RHI and enable any debug layers up-front As [1] shows, creating a D3D12 device and then enabling debug layers causes future device creation to fail. That means enabling debug layers is a process-wide decision that should be done at startup, and not just before creating an individual device. Previously, Slang-RHI enabled debug layers as part of device creation. The new Slang-RHI revision doesn't do that anymore, but instead allows the user to enable debug layers earlier, with a separate API. This change calls the mentioned API before creating any device. This closes #6172. * Compile fixes needed after updating slang-rhi --------- Co-authored-by: Yong He <yonghe@outlook.com>

2025-01-31Respect per-target debug options (#6193)Anders Leino
* Base compiler options for targets on target-specific compiler options Before this change, the target compiler options were based on the linkage-wide compiler options, which where later again inherited from (basically a no-op). With this change, the target-specific compiler options are added first, and then the linkage-wide comnpiler options are inherited from. * Remove debug instructions if target-specific setting is NONE This helps to address #6092. * Make sure the linkage debug info level is sufficient for each target This closes #6092.

2025-01-27Add an example for reflection of parameter blocks (#6161)Theresa Foley
* Add an example for reflection of parameter blocks The example loads a shader program, compiles it for Vulkan, and then uses reflection information to set up descriptor set layouts and a pipeline layout. It then validates that the pipeline layout that is created is compatible with the compiled code, by using them together to make a pipeline state object with the validation layer enabled. The basic flow of the application follows the presentation in the companion article, and references its sections. This is example could be expanded in a few ways: * A D3D12 path could be added, to show the comparable operations for creating a root signature from reflection data * The existing shader could be modified to touch/use more of its parameter data, to help ensure that any errors would be caught by the validation layer * The set of shader files/modules that get loaded automatically could be expanded, to test more cases * The code could be expanded to handle more than just compute shaders, by allowing for multiple-entry-point files to be loaded for rasterization or ray-tracing pipelines * format code * fixup: build errors * format code * fixups for build * fixup * fixup --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>
