cmd/link: support new 386/amd64 relocations The GNU binutils recently picked up support for new 386/amd64 relocations. Add support for them in the Go linker when doing an internal link. The 386 relocation R_386_GOT32X was proposed in https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I . It can be treated as identical to the R_386_GOT32 relocation. The amd64 relocations R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX were proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 . They can both be treated as identical to the R_X86_64_GOTPCREL relocation. The purpose of the new relocations is to permit additional linker relaxations in some cases. We do not attempt to support those cases. While we're at it, remove the unused and in some cases out of date _COUNT names from ld/elf.go. Fixes #13114.

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

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!

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
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.
