When processing a fallthrough, the casebody function in swt.go checks that the last statement has indeed Op == OXFALL (not-processed fallthrough) before setting it to OFALL (processed fallthrough). Unfortunately, sometimes the fallthrough statement won't be in the last node. For example, in case 0: return func() int {return 1}() fallthrough the compiler generates autotmp_0 = (func literal)(); return autotmp_0; fallthrough; <node VARKILL> with an OVARKILL node in the last position. casebody will find that last.Op != OXFALL, won't mark the fallthrough as processed, and the fallthrough line will cause a "fallthrough statement out of place" error. To fix this, we change casebody so that it searches for the fallthrough statement backwards in the statements list, without assuming that it'll be in the last position.

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

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.
