CL 62250 makes constant folding a bit more aggressive and these benchmarks were optimized away. This CL adds some indirection to the function arguments to stop them being folded. The Copysign benchmark is a bit faster because I've left one argument as a constant and it can be partially folded. old CL 62250 this CL Copysign 1.24ns ± 0% 0.34ns ± 2% 1.02ns ± 2% Abs 0.67ns ± 0% 0.35ns ± 3% 0.67ns ± 0% Signbit 0.87ns ± 0% 0.35ns ± 2% 0.87ns ± 1% Change-Id: I9604465a87d7aa29f4bd6009839c8ee354be3cd7 Reviewed-on: https://go-review.googlesource.com/62450 Run-TryBot: Michael Munday <mike.munday@ibm.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>
