Before, an unnamed return value turned into an ONAME node n with n->sym named ~anon%d, and n->orig == n. A blank-named return value turned into an ONAME node n with n->sym named ~anon%d but n->orig == the original blank n. Code generation and printing uses n->orig, so that this node formatted as _. But some code does not use n->orig. In particular the liveness code does not know about the n->orig convention and so mishandles blank identifiers. It is possible to fix but seemed better to avoid the confusion entirely. Now the first kind of node is named ~r%d and the second ~b%d; both have n->orig == n, so that it doesn't matter whether code uses n or n->orig. After this change the ->orig field is only used for other kinds of expressions, not for ONAME nodes. This requires distinguishing ~b from ~r names in a few places that care. It fixes a liveness analysis bug without actually changing the liveness code. TBR=ken2 CC=golang-codereviews https://golang.org/cl/63630043 |

README
This is the source code repository for the Go programming language.
For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install-source.html
in your web browser.
After installing Go, you can view a nicely formatted
doc/install-source.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install/source.
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 README). 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.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 doc/install.html for more details.
