runtime: replace needwb() with writeBarrierEnabled Reduce the write barrier check to a single load and compare so that it can be inlined into write barrier use sites. Makes the standard write barrier a little faster too. name old new delta BenchmarkBinaryTree17 17.9s × (0.99,1.01) 17.9s × (1.00,1.01) ~ BenchmarkFannkuch11 4.35s × (1.00,1.00) 4.43s × (1.00,1.00) +1.81% BenchmarkFmtFprintfEmpty 120ns × (0.93,1.06) 110ns × (1.00,1.06) -7.92% BenchmarkFmtFprintfString 479ns × (0.99,1.00) 487ns × (0.99,1.00) +1.67% BenchmarkFmtFprintfInt 452ns × (0.99,1.02) 450ns × (0.99,1.00) ~ BenchmarkFmtFprintfIntInt 766ns × (0.99,1.01) 762ns × (1.00,1.00) ~ BenchmarkFmtFprintfPrefixedInt 576ns × (0.98,1.01) 584ns × (0.99,1.01) ~ BenchmarkFmtFprintfFloat 730ns × (1.00,1.01) 738ns × (1.00,1.00) +1.16% BenchmarkFmtManyArgs 2.84µs × (0.99,1.00) 2.80µs × (1.00,1.01) -1.22% BenchmarkGobDecode 39.3ms × (0.98,1.01) 39.0ms × (0.99,1.00) ~ BenchmarkGobEncode 39.5ms × (0.99,1.01) 37.8ms × (0.98,1.01) -4.33% BenchmarkGzip 663ms × (1.00,1.01) 661ms × (0.99,1.01) ~ BenchmarkGunzip 143ms × (1.00,1.00) 142ms × (1.00,1.00) ~ BenchmarkHTTPClientServer 132µs × (0.99,1.01) 132µs × (0.99,1.01) ~ BenchmarkJSONEncode 57.4ms × (0.99,1.01) 56.3ms × (0.99,1.01) -1.96% BenchmarkJSONDecode 139ms × (0.99,1.00) 138ms × (0.99,1.01) ~ BenchmarkMandelbrot200 6.03ms × (1.00,1.00) 6.01ms × (1.00,1.00) ~ BenchmarkGoParse 10.3ms × (0.89,1.14) 10.2ms × (0.87,1.05) ~ BenchmarkRegexpMatchEasy0_32 209ns × (1.00,1.00) 208ns × (1.00,1.00) ~ BenchmarkRegexpMatchEasy0_1K 591ns × (0.99,1.00) 588ns × (1.00,1.00) ~ BenchmarkRegexpMatchEasy1_32 184ns × (0.99,1.02) 182ns × (0.99,1.01) ~ BenchmarkRegexpMatchEasy1_1K 1.01µs × (1.00,1.00) 0.99µs × (1.00,1.01) -2.33% BenchmarkRegexpMatchMedium_32 330ns × (1.00,1.00) 323ns × (1.00,1.01) -2.12% BenchmarkRegexpMatchMedium_1K 92.6µs × (1.00,1.00) 89.9µs × (1.00,1.00) -2.92% BenchmarkRegexpMatchHard_32 4.80µs × (0.95,1.00) 4.72µs × (0.95,1.01) ~ BenchmarkRegexpMatchHard_1K 136µs × (1.00,1.00) 133µs × (1.00,1.01) -1.86% BenchmarkRevcomp 900ms × (0.99,1.04) 900ms × (1.00,1.05) ~ BenchmarkTemplate 172ms × (1.00,1.00) 168ms × (0.99,1.01) -2.07% BenchmarkTimeParse 637ns × (1.00,1.00) 637ns × (1.00,1.00) ~ BenchmarkTimeFormat 744ns × (1.00,1.01) 738ns × (1.00,1.00) -0.67% Change-Id: I4ecc925805da1f5ee264377f1f7574f54ee575e7 Reviewed-on: https://go-review.googlesource.com/9321 Reviewed-by: Austin Clements <austin@google.com>
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Please report issues here: https://golang.org/issue/new
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
