[ExecuTorch][WebGPU] Tests for the q4gsw_train WebGPU ops by JCNTH · Pull Request #20932 · pytorch/executorch

JCNTH · 2026-07-14T21:49:19Z

Stack from ghstack (oldest at bottom):

Export-delegation + fp64 golden tests for the q4gsw training (backward, dw, requant) ops.

Key changes:

test/ops/{test_quantized_linear_backward,test_linear_q4gsw_dw,test_q4gsw_requant}.py — fp64 dequant-matmul / weight-grad / re-quant goldens + a round-trip + delegation checks — fp64 library-reference goldens + delegation checks (≥2 cases/op).
