Introduce an op MOVWaddr for addresses on ARM, instead of overuse ADDconst. Mark MOVWaddr as rematerializable. This fixes a liveness problem: if it were not rematerializable, the address of a variable may be spilled and later use of the address may just load the spilled value without mentioning the variable, and the liveness code may think it is dead prematurely. Update #15365. Change-Id: Ib0b0fa826bdb75c9e6bb362b95c6cf132cc6b1c0 Reviewed-on: https://go-review.googlesource.com/23942 Reviewed-by: David Chase <drchase@google.com> |

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

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.
