# Run the x86_64 test suite under Intel SDE with Ice Lake (`-icx`)
# emulation. The standard ubuntu-latest runner is AMD Milan (no
# native AVX-512), so without SDE the AVX-512 kernel's
# `is_x86_feature_detected!("avx512bw")` gate returns false and the
# AVX-512 dispatch branch never executes. With SDE, `-icx` reports
# AVX-512F/BW/DQ/VL via its CPUID intercept, so every x86 SIMD tier
# (SSE4.2, AVX2, AVX-512BW) executes and is verified against the scalar
# reference.
#
# SDE slowdown is ~5-10×, so the test suite runs in ~30-60s instead
# of ~1s — still well within the free-runner budget.
