[Qemu-devel] [PATCH v6 12/13] hardfloat: implement float32/64 square root

Performance results for fp-bench: Host: Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz - before: sqrt-single: 42.30 MFlops sqrt-double: 22.97 MFlops - after: sqrt-single: 311.42 MFlops sqrt-double: 311.08 MFlops Here USE_FP makes a huge difference for f64's, with throughput going from ~200 MFlops to
