Ilya Tocar 94484d8ed5 cmd/compile: intrinsify math.{Trunc/Ceil/Floor} on amd64 ... This significantly speed-ups Trunc. Ceil/Floor are using the same instruction, so do them too. name old time/op new time/op delta Floor-6 3.33ns ± 1% 3.22ns ± 0% -3.39% (p=0.000 n=10+10) Ceil-6 3.33ns ± 1% 3.22ns ± 0% -3.16% (p=0.000 n=10+7) Trunc-6 4.83ns ± 0% 3.22ns ± 0% -33.36% (p=0.000 n=6+8) Change-Id: If848790e458eedfe38a6a0407bb4f589c68ac254 Reviewed-on: https://go-review.googlesource.com/68630 Run-TryBot: Ilya Tocar <ilya.tocar@intel.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>		2017-10-31 19:30:54 +00:00
