Change the linker to use a copy of the C compiler support library, libgcc.a, when doing internal linking. This will be used to satisfy any undefined symbols referenced by host objects. Change the dist tool to copy the support library into a new directory tree under GOROOT/pkg/libgcc. This ensures that libgcc is available even when building Go programs on a system that has no C compiler. The C compiler is required when building the Go installation in the first place, but is not required thereafter. Change the go tool to not link libgcc into cgo objects. Correct the linker handling of a weak symbol in an ELF input object to not always create a new symbol, but to use an existing symbol if there is one; this is necessary on freebsd-amd64, where libgcc contains a weak definition of compilerrt_abort_impl. Fixes #9510. Change-Id: I1ab28182263238d9bcaf6a42804e5da2a87d8778 Reviewed-on: https://go-review.googlesource.com/16741 Reviewed-by: Russ Cox <rsc@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.
