2025-01-27Fix an incorrect iteration with a workList (#6177)Jay Kwak
* Fix an incorrect iteration with a workList We cannot modify workList while iterating it, because its type `List` is actually an array container. * Change based on the feedback * Use `Index` instead of `int` for for-loop index --------- Co-authored-by: Yong He <yonghe@outlook.com>

2025-01-23Fix incorrect resolve of specialization instance (#6162)Jay Kwak
* Fix incorrect resolve of specialization instance While checking the uninitialized variables, we were not resolving the specialized instance correctly. This commit repeats the resolve while the result is a specialization instance. A new test is added for this: tests/diagnostics/uninitialized-generic.slang After the problem is fixed, it revealed another problem in existing tests: tests/compute/nested-generics2.slang tests/diagnostics/uninitialized-local-variables.slang When a struct has a member variable whose type is a generic type, we cannot iterate over its member variables yet, because the type is unknown until the generic function/struct is specialized. We will have to give up checking for these cases.
2025-01-22Cache and reuse glsl module. (#6152)Yong He
* Cache and reuse glsl module. * Fix. * Implement record/replay for the new api. * Fix record replay. * Fix test.
2025-01-22Add validation for destination of atomic operations (#6093)Anders Leino
* Reimplement the GLSL atomic* functions in terms of __intrinsic_op Many of these functions map directly to atomic IR instructions. The functions taking atomic_uint are left as they are. This helps to address #5989, since the destination pointer type validation can then be written only for the atomic IR instructions. * Add validation for atomic operations Diagnose an error if the destination of the atomic operation is not appropriate, where appropriate means it's either: - 'groupshared' - from a device buffer This closes #5989. * Add tests for GLSL atomics destination validation Attempting to use the GLSL atomic functions on destinations that are neither groupshared nor from a device buffer should fail with the following error: error 41403: cannot perform atomic operation because destination is neither groupshared nor from a device buffer. * Validate atomic operations after address space specialization Address space specialization for SPIR-V is not done as part of `linkAndOptimizeIR`, as it is for e.g. Metal, so opt out and add a separate call for SPIR-V. * Allow unchecked in/inout parameters for non-SPIRV targets * Clean up callees left without uses during address space specialziation * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>

2025-01-21Fix bug: IgnoreInheritance in lookup (#6146)kaizhangNV
* Fix bug: IgnoreInheritance in lookup When specifying IgnoreInheritance in lookup, it will ignore all members in the self extension for generic, the reason is that it doesn't specialize the target type of the extension decl when comparing with self type, so it will result that every type is unequal to the target type.

2025-01-14Fix simplify if-else (#6077)cheneym2
* Fix simplify if-else The if-else optimization observes that at if at least one true/false block is merely an unconditional jump to the after block, that the whole if-else can be replaced with a jump to the after block. But it's important to copy the phi arguments from the aforementioned unconditional jump, rather than what is present in the 'true' block, since the 'true' block might actually just be the after block itself. Below, the ifElse() would be replaced with an unconditional jump to block %39, but with the `phi` arguments copied from the branch to %29, which is an unrelated block. ifElse(%38, %39, %40, %39) block %40: unconditionalBranch(%39) block %39: unconditionalBranch(%29, 0 : Float) block %29( [nameHint("ret")] param %ret : Float): Fixes issue #5972 * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>
