Some applications built with Go on ppc64x with external linking can fail to link with relocation truncation errors if the elf text section that is generated is larger than 2^26 bytes and that section contains a call instruction (bl) which calls a function beyond the limit addressable by the 24 bit field in the instruction. This solution consists of generating multiple text sections where each is small enough to allow the GNU linker to resolve the calls by generating long branch code where needed. Other changes were added to handle differences in processing when multiple text sections exist. Some adjustments were required to the computation of a method's address when using the method offset table when there are multiple text sections. The number of possible section headers was increased to allow for up to 128 text sections. A test case was also added. Fixes #15823.

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.
