From b5f7ff4aa9c1fef6437f350595caae4ee4b5708d Mon Sep 17 00:00:00 2001 From: Dmitri Shuralyov Date: Fri, 1 May 2020 18:58:41 -0400 Subject: [PATCH] all: update vendored dependencies for Go 1.15 release The Go 1.15 code freeze has just started. This is the time to update all golang.org/x/... module versions that contribute packages to the std and cmd modules in the standard library to latest master versions. Those versions have already gone through code review, and now they will undergo additional testing during the freeze period. If there are new issues in these dependencies discovered, we have the freeze period to deal with that. By the end of the freeze period, we will have confidence that the Go 1.15 release and the dependency versions it has selected are robust. If one of the Go 1.15.x minor releases requires changing code in one of the vendored packages, we'll be able to do so on top of the versions that are selected here, and not be forced to use versions that came from different time periods, or try to jump across multiple untested versions in a minor release. The dependency versions that are selected in this commit are: github.com/google/pprof v0.0.0-20200229191704-1ebb73c60ed3 github.com/ianlancetaylor/demangle v0.0.0-20200414190113-039b1ae3a340 golang.org/x/arch v0.0.0-20200312215426-ff8b605520f4 golang.org/x/crypto v0.0.0-20200429183012-4b2356b1ed79 golang.org/x/mod v0.2.1-0.20200429172858-859b3ef565e2 golang.org/x/net v0.0.0-20200501053045-e0ff5e5a1de5 golang.org/x/sys v0.0.0-20200501145240-bc7a7d42d5c3 golang.org/x/text v0.3.3-0.20200430171850-afb9336c4530 golang.org/x/tools v0.0.0-20200504152539-33427f1b0364 golang.org/x/xerrors v0.0.0-20191204190536-9bdfabe68543 github.com/ianlancetaylor/demangle is considered in scope and updated. github.com/google/pprof is out of scope and was not updated.

For compatibility with the generic +// implementation we perform this summation at the end of every +// updateVX call. +// +// To use two accumulators we must multiply the message blocks +// by r² rather than r. Only the final message block should be +// multiplied by r. +// +// Example: +// +// We want to calculate the sum (h) for a 64 byte message (m): +// +// h = m[0:16]r⁴ + m[16:32]r³ + m[32:48]r² + m[48:64]r +// +// To do this we split the calculation into the even indices +// and odd indices of the message. These form our SIMD 'lanes': +// +// h = m[ 0:16]r⁴ + m[32:48]r² + <- lane 0 +// m[16:32]r³ + m[48:64]r <- lane 1 +// +// To calculate this iteratively we refactor so that both lanes +// are written in terms of r² and r: +// +// h = (m[ 0:16]r² + m[32:48])r² + <- lane 0 +// (m[16:32]r² + m[48:64])r <- lane 1 +// ^ ^ +// | coefficients for second iteration +// coefficients for first iteration +// +// So in this case we would have two iterations. In the first +// both lanes are multiplied by r². In the second only the +// first lane is multiplied by r² and the second lane is +// instead multiplied by r.
