Rob Pike 29428e322d [dev.cc] cmd/asm: check for overflow on multiply and left shift 
The internal size of integers is not part of the definition of the assembler,
so if bits roll out the top it's a portability problem at best.

If you need to use shift to create a mask, use & to restrict the bit count
before shifting. That will make it portable, too.

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.
