This helps follow-up CLs ensure that the encoding's core computation does not allocate. It is a separate CL because it has a non-trivial effect on the benchmark numbers, even if it's purely an accounting change and not a change to the underlying performance: BenchmarkEncodeDigitsSpeed1e4-4 5.65 19.31 3.42x BenchmarkEncodeDigitsSpeed1e5-4 17.23 26.79 1.55x BenchmarkEncodeDigitsSpeed1e6-4 26.85 27.51 1.02x BenchmarkEncodeDigitsDefault1e4-4 4.41 13.21 3.00x BenchmarkEncodeDigitsDefault1e5-4 5.64 6.28 1.11x BenchmarkEncodeDigitsDefault1e6-4 5.54 5.65 1.02x BenchmarkEncodeDigitsCompress1e4-4 4.31 13.15 3.05x BenchmarkEncodeDigitsCompress1e5-4 5.52 5.91 1.07x BenchmarkEncodeDigitsCompress1e6-4 5.38 5.63 1.05x BenchmarkEncodeTwainSpeed1e4-4 5.45 19.06 3.50x BenchmarkEncodeTwainSpeed1e5-4 17.30 29.25 1.69x BenchmarkEncodeTwainSpeed1e6-4 28.06 30.86 1.10x BenchmarkEncodeTwainDefault1e4-4 4.06 12.36 3.04x BenchmarkEncodeTwainDefault1e5-4 6.15 7.62 1.24x BenchmarkEncodeTwainDefault1e6-4 6.84 6.99 1.02x BenchmarkEncodeTwainCompress1e4-4 4.06 12.27 3.02x BenchmarkEncodeTwainCompress1e5-4 5.29 5.92 1.12x BenchmarkEncodeTwainCompress1e6-4 5.24 5.29 1.01x Change-Id: I7d32866b7e2d478b0154332c1edeefe339af9a28 Reviewed-on: https://go-review.googlesource.com/20467 Reviewed-by: David Symonds <dsymonds@golang.org>
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.
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
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

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.
