cmd/internal/obj: make Prog.From3 a pointer It is almost never set and Addr is large, so having the full struct in the Prog wastes memory most of the time. Before (on a 64-bit system): $ sizeof -p cmd/internal/obj Addr Prog Addr 80 Prog 376 $ After: $ sizeof -p cmd/internal/obj Addr Prog Addr 80 Prog 304 $ Change-Id: I491f201241f87543964a7d0f48b85830759be9d0 Reviewed-on: https://go-review.googlesource.com/10457 Reviewed-by: Josh Bleecher Snyder <josharian@gmail.com>

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
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.
