Josh Bleecher Snyder 080e2d4320 cmd/compile: don’t generate Nodes for PCDATA 
We were allocating two Nodes just to help Naddr
fill in Type and Offset.
Fill them in directly instead.

Passes toolstash -cmp.

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!

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.
