Add direct usage support for gl_DrawID (#8594)

2025-10-03T19:52:50+00:00

- [x] Add `gl_DrawID` property declaration in `source/slang/glsl.meta.slang` similar to `gl_BaseVertex` and `gl_BaseInstance` - [x] Ensure it maps to `SV_DrawIndex` semantic - [x] Add extension requirements in `slang-ir-glsl-legalize.cpp` (GLSL 460 and GL_ARB_shader_draw_parameters) - [x] Create test case to verify SPIRV output contains `DrawIndex` decoration - [x] Run formatting script before committing - [x] Verify existing tests still pass - [x] Remove accidentally committed temp files (1.glsl, 3.spv-asm) - [x] Update .gitignore to prevent similar files from being committed

In vulkan though, i should be able to use it directly, but because now i store it as a global variable, i cannot use the SV_DrawIndex semantic either. > > # Preferred Solution > I'd like to be able to use gl_DrawID like you how can use gl_BaseVertex and gl_BaseInstance. > > > You can just edit glsl.meta.slang and add a declaration for gl_DrawID in a similar way to gl_BaseVertex, and map it to SV_DrawIndex. > > Create a `//TEST:SIMPLE(filecheck=SPIRV): -target spirv` test case, and use filecheck to verify the output contains the correct SPIRV `DrawIndex` decoration. > > ## Comments on the Issue (you are @copilot in this section) > > > >

Disable a few WGSL testing using Wave functions in branches (#8386)

2025-09-06T01:51:47+00:00

WGSL requires Wave functions to be used only in uniform control flow. The latest compiler, Tint, started to error out when Wave functions are used in a dynamic control flow. This commit disables some of tests using Wave functions in dynamic branches. If possible, they are altered to call Wave functions in uniform control flows.

render-test: Change D3D12 default to sm_6_5 (#8320)

2025-09-02T23:43:48+00:00

Changes default for render-test to sm_6_5. Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it. Fixes #7611

[Capability System] Fix bug where capabilities do not correctly propegate if AST-parent has target+set the AST-child does not (#8175)

2025-08-14T19:27:55+00:00

Fixes: #8174 Changes: * To determine if we propagate capabilities, we need to ensure that a `join` will do nothing (optimization since `join` is expensive + caching data for the `join` adds up to be expensive). This logic was changed in `slang-check-decl.cpp` since the current logic was incorrect. * A parent could have the set `metal+glsl` and the use-site could have `glsl`. In this case, we will not remove `metal` from the parent since `{metal+glsl}.implies({glsl})` is true. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Fix intermittent debug failures with Debug build (#7369)

2025-06-12T05:33:16+00:00

This PR replaces enable/disable style C function calls with C++ RAII style code. In debug build, when an assertion failed in between enable and disable functions, an exception is thrown and the disable function is not called. RAII style code is safer for an exception
