The Go programming language

The entry for LEAL/LEAQ in these optabs was listed as having two data bytes in the y array. In fact they had and expect no data bytes. However, the general loop expects to be able to look at at least one data byte, to make sure it is not 0x0f. So give them each a single data byte set to 0 (not 0x0f). Since the MOV instructions have the largest optab cases, this requires growing the size of the data array. Clang found this bug because the general o->op[z] == 0x0f test was using z == 22, which was out of bounds. In practice the next byte in memory was probably not 0x0f so it wasn't truly broken. But might as well be clean. Update #5764 R=ken2 CC=golang-dev https://golang.org/cl/13241050 |

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.
