The object file reader in cmd/link reads the symbol name into a scratch []byte, converts it to a string, and then does a substring replacement. Instead, this CL does the replacement on the []byte into the scratch space and then creates the final string. Linking godoc without DWARF, best of ten, shows a ~10% improvement. tip: real 0m1.099s user 0m1.541s this: real 0m0.990s user 0m1.280s This is part of an attempt to make suffixarray string deduping come out as a wash, but it's not there yet: cl/19987: real 0m1.335s user 0m1.794s cl/19987+this: real 0m1.225s user 0m1.540s Change-Id: Idf061fdfbd7f08aa3a1f5933d3f111fdd1659210 Reviewed-on: https://go-review.googlesource.com/20025 Reviewed-by: Ian Lance Taylor <iant@golang.org> Run-TryBot: David Crawshaw <crawshaw@golang.org> Reviewed-by: Brad Fitzpatrick <bradfitz@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.
Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.

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.
