[ExecuTorch][WebGPU] Flatten landed-op test dirs to test/ops/test_<op>.py by JulianCloudNTH · Pull Request #20435 · pytorch/executorch

JulianCloudNTH · 2026-06-22T20:40:39Z

Stack from ghstack (oldest at bottom):

Pure test-file relocation: moves the already-landed ops' tests from nested test/ops/<op>/test_<op>.py to flat test/ops/test_<op>.py, matching the ExecuTorch convention (XNNPACK uses flat test/ops/test_<op>.py; Vulkan uses flat test/test_*.py) and completing the flatten applied to the new ops in the stack below. Drops the per-op __init__.py; the parent test/ops/__init__.py is kept. Ops: add, rms_norm, sdpa (test_sdpa + test_update_cache), dispatch_order, quantized_linear, embedding_q4gsw, rope, prepack.

No behavior change — the test modules and their export/golden functions are unchanged; only their path moves. Every reference to the old paths is updated: the cases.py op-test imports (add, rms_norm), test/TARGETS (test_add srcs), test/ops/test_dispatch_order.py's internal rms_norm import, and the build/CI scripts that import the per-op export functions (test/test_build_webgpu.sh, scripts/test_webgpu_native_ci.sh).

Nothing required the per-op subdirectory: the codegen framework imports only cases.py, the one buck target uses a literal path, and the native-golden scripts import the modules by path — each resolves identically at the flat path.

On the Llama critical path (`F.silu` -> `sigmoid` + `mul`). Composition (single dispatch): - `sigmoid/UnaryOp.cpp` — binds input (storage, read-only) + output (storage) + a `Params{num_elements}` uniform, 1D-dispatches over `num_elements` with `override wg_size` (clamped to the device limit); mirrors the `add` op (uniform mapped-at-creation, released after the bind group). - `sigmoid/sigmoid.wgsl` — guards `idx >= num_elements` and writes the logistic of each element. @exported-using-ghexport Differential Revision: [D108793157](https://our.internmc.facebook.com/intern/diff/D108793157/) Differential Revision: [D108793157](https://our.internmc.facebook.com/intern/diff/D108793157)
