Defer `IRCastStorageToLogicalDeref` in lowerBufferElementType pass. (#8668)

2025-10-10T01:30:24+00:00

Fix a regression on metal test. In `lowerBufferElementTypeToStorageType` pass, not only we want to defer an argument that is `CastStorageToLogical` to the callee, but also apply the same defer logic to `CastStorageToLogicalDeref` as well. Because `CastStorageToLogicalDeref` will appear as argumnet if `lowerBufferElementTypeToStorageType` is run before we apply the `in->borrow` transformation pass, which is the case for metal parameter block legalization.

WGSL: Fix issue where global calls are generated (#5768)

2024-12-12T18:09:18+00:00

* Split out SPIR-V -specific legalization of global functions This is a refactoring and should not affect generated code. * Move global inst inlining code into separate function This is a refactoring and should not affect generated code. * Take SPIR-V -specific parts out of GlobalInstInliningContext This is a refactoring and should not affect generated code. * Move 'inlineGlobalValues' to generic inlining context This is a refactoring and should not affect generated code. * Move 'setInsertBeforeOutsideASM' to generic inlining context This is a refactoring and should not affect generated code. * Move generic inlining context into own file This is a refactoring and should not affect generated code. * Run global inlining for WGSL as well * Make the 'getOutsideASM' function generic as well * Enable language-feature/constants/static-const-in-generic-interface.slang for WebGPU * Clarify when it's safe to remove and deallocate an IRInst * Remove globals if they're left unused after inlining This closes #5607. * Handle IRGlobalValueRef in C-like emitter * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Support interpolation modifiers for WGSL (#5641)

2024-11-25T14:05:13+00:00

* wgsl: Support interpolation modifiers * Move struct key decorations to flattened structs. ** This includes interpolation mode decorations, which must be in the flattened struct. * Emit interpolation attribute. * Enable tests/render/nointerpolation.hlsl for WGSL, as a result.
