Enforce rule that `export`/`extern` (non cpp) must be `const` (#7113)

2025-05-16T17:44:44+00:00

* Enforce rule that `export`/`extern` (non cpp) must be `const` fixes: #5570 Problem: 1. we allow non-const-link-time-var to be linked to a const-link-time-var. 2. problem is that: module use site has const var, so, we emit OpStore %Ptr %Const in IR, this is expected, this is good. We fail because we in reality have a OpStore %Ptr %Var (fails since we need a OpLoad in-between) in IR since the module with our link-time-variable-value is a regular variable. 3. We loose the float_litteral talked about inside the github issue since, we technically don't use our variable "VAL" (we never OpLoad from it), so spirv-opt removes the float_litteral, this is a byproduct of the actual issue. Solution: * `export`/`extern` variables must always be `const`. This excludes `__extern_cpp` since `cpp` does not exhibit this issue and works differently. * format code * changel logic and tests to only ensure `static const` with `export`/`extern` * changing the rules: only reqirement is that if we have const we must have static * remove a spirrious change made * fix merge --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He

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>

Refresh of disabled WGPU tests (#5614)

2024-11-21T07:37:28+00:00

Some tests are now passing and are enabled. Other tests are still failing, but are given comments categorizing the failures. Tests in the 'Not supported in WGSL' category are also removed from the expected failures list. (Though they are still kept disabled for WebGPU, of course.) This closes #5519.

Various WGSL fixes. (#5490)

2024-11-05T01:37:50+00:00

* [WGSL] make sure switch has a default label. * Various WGSL fixes. * Update rhi submodule commit * format code * Remove unnecessary DISABLE_TEST directive on not applicable test. * Matrix comp mul + `select`. * Legalize binary ops for wgsl. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
