about

nx_simd_usat_shift_test.nx -- unsigned saturating arith + per-lane shifts (i16x16). Two primitive families exercised in one smoke: vsaddu / vssubu -- unsigned saturating add/sub. Required for RGBA channel data (signed sat would clip at 32767 instead of 65535, mangling bright channels). Maps to vpaddusw/vpsubusw on x86 and vsaddu.vv/vssubu.vv on RV-V. vsll / vsrl / vsra -- per-lane immediate shifts. Image processing channel shuffles (pack ARGB into 5-6-5), crypto round shifts, fast pow-of-2 multiply/divide. Maps to vpsllw/vpsrlw/vpsraw on x86 and vsll.vx/vsrl.vx/vsra.vx on RV-V.
