There are still two places in src/runtime/string.go that use staticbytes, so we cannot delete it just yet. There is a new codegen test to verify that the index calculation is constant-folded, at least on amd64. ppc64, mips[64] and s390x cannot currently do that. There is also a new runtime benchmark to ensure that this does not slow down performance (tested against parent commit): name old time/op new time/op delta ConvT2EByteSized/bool-4 1.07ns ± 1% 1.07ns ± 1% ~ (p=0.060 n=14+15) ConvT2EByteSized/uint8-4 1.06ns ± 1% 1.07ns ± 1% ~ (p=0.095 n=14+15) Updates #37612 Change-Id: I5ec30738edaa48cda78dfab4a78e24a32fa7fd6a Reviewed-on: https://go-review.googlesource.com/c/go/+/221957 Run-TryBot: Ian Lance Taylor <iant@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Josh Bleecher Snyder <josharian@gmail.com>
