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> |

The Go Programming Language
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
Please note that we do not use pull requests.

Binary Distribution Notes
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.
