Andreas Auernhammer cd11541cdf curve25519: improve cswap ... Simplify the constant swap function. On amd64: Replace the CMOVQEQ scheme with SSE2 code similar to the non-amd64 code. On non-amd64: Avoid unnecessary loop iterations. The result is less and slightly faster code. name old time/op new time/op delta ScalarBaseMult-4 653µs ± 0% 636µs ± 0% ~ (p=0.100 n=3+3) name old time/op new time/op delta ConstantSwap-4 10.4ns ± 1% 6.2ns ± 0% -39.86% (p=0.029 n=4+4) On an i7-65000U Change-Id: Ia5eea92e0b3eabb6c291d25229aa582b51278552 Reviewed-on: https://go-review.googlesource.com/39693 Reviewed-by: Adam Langley <agl@golang.org> Run-TryBot: Adam Langley <agl@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>		2017-04-13 00:59:54 +00:00
