The Go programming language
1806a5732b
We need to change the interface value representation for concurrent garbage collection, so that there is no ambiguity about whether the data word holds a pointer or scalar. This CL does NOT make any representation changes. Instead, it removes representation assumptions from various pieces of code throughout the tree. The isdirectiface function in cmd/gc/subr.c is now the only place that decides that policy. The policy propagates out from there in the reflect metadata, as a new flag in the internal kind value. A follow-up CL will change the representation by changing the isdirectiface function. If that CL causes problems, it will be easy to roll back. Update #8405.

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.
