feat(graphics): expose WGSL pointer_composite_access as a device cap#8786
Merged
Conversation
Adds detection and automatic wiring for the WGSL `pointer_composite_access` language feature, which provides syntactic sugar for dereferencing pointers to composite types — `p.field` and `p[i]` instead of `(*p).field` and `(*p)[i]`. Follows the same pattern as `unrestricted_pointer_parameters` and `linear_indexing`: - `supportsPointerCompositeAccess` device flag, probed from navigator.gpu.wgslLanguageFeatures. - `CAPS_POINTER_COMPOSITE_ACCESS` shader define for conditional compilation. - `requires pointer_composite_access;` directive automatically injected into WGSL shaders on supporting devices. See https://developer.chrome.com/blog/new-in-webgpu-123#syntax_sugar_for_dereferencing_composites_in_wgsl

pointer_composite_accesslanguage feature, which provides syntactic sugar for dereferencing pointers to composite types —p.fieldandp[i]instead of(*p).fieldand(*p)[i].Follows the same pattern as
unrestricted_pointer_parameters(#8785) andlinear_indexing.Changes:
GraphicsDevice.supportsPointerCompositeAccessflag, probed fromnavigator.gpu.wgslLanguageFeaturesinWebgpuGraphicsDevice#initDeviceCaps.CAPS_POINTER_COMPOSITE_ACCESSshader define for conditional compilation (#ifdef).requires pointer_composite_access;directive automatically injected into WGSL shaders on supporting devices viaShaderDefinitionUtils.getWGSLEnables.Notes:
falsethere and norequiresdirective is emitted, so existing portable shaders continue to compile.
