Using the type of the store argument is not safe, it may change during rewriting, giving us the wrong store width. (Store ptr (Trunc32to16 val) mem) This should be a 2-byte store. But we have the rule: (Trunc32to16 x) -> x So if the Trunc rewrite happens before the Store -> MOVW rewrite, then the Store thinks that the value it is storing is 4 bytes in size and uses a MOVL. Bad things ensue. Fix this by encoding the store width explicitly in the auxint field. In general, we can't rely on the type of arguments, as they may change during rewrites. The type of the op itself (as used by the Load rules) is still ok to use.

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.
