For debugging, spill values to named variables instead of autotmp_ variables if possible. We do this by keeping a name -> value map for each function, keep it up-to-date during deadcode elim, and use it to override spill decisions in stackalloc. It might even make stack frames a bit smaller, as it makes it easy to identify a set of spills which are likely not to interfere. This just works for one-word variables for now. Strings/slices will be a separate CL.

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

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.
