This change omits the stack check on ppc64 and s390x when the size of a stack frame is less than obj.StackSmall. This is an optimization x86 already performs. The effect on s390x isn't huge because we were already omitting the stack check when the frame size was 0 (it shaves about 1K from the size of bin/go). On ppc64 however this change reduces the size of the .text section in bin/go by 33K (1%). Updates #13379 (for ppc64).

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

Go is the work of hundreds of contributors. We appreciate your help!

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.
