On s390x char is unsigned. We cannot force it to be signed using -fsigned-char (see arm64) because the s390x gccgo API is already public and we need to stick as closely as possible to it to avoid breaking existing projects. In order to match the gccgo API we also force the RawSockaddr.Data and RawSockaddrUnix.Path fields to be signed. This CL adds a post-processing pass (mkpost.go) to mkall.sh in order to export the types of fields in PtraceRegs on s390x without affecting the API on other platforms. The types of these fields match their counterparts in gccgo. mkpost.go also cleans up the Pad_cgo* fields and X_* fields (these fields are not exported by gccgo currently). It could be extended to add build tags on platforms that need them.

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.
