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.

[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

Implement subgroup quad operations for Metal (#6745)

2025-04-04T23:46:28+00:00

Migrate render-test away from deprecated compile request API (#6514)

2025-03-12T11:44:57+00:00

* Add a simple interface parameter test Since there's no documentation, it's nice to have a simple test case in order to experiment with this feature of the testing framework. * Add shader entry point attributes to tests * Fix specialization arguments for tests - Add some missing arguments - Rremove one extraneous argument. * Stop using deprecated compile request in render-test Use a session object instead of the deprecated compile request object. This closes issue #4760.
