The Go programming language
fff732ea2c
This changes makes constant propagation compare 'from' values using node pointers rather than symbol names when checking to see whether a set operation is redundant. When a function is inlined multiple times in a calling function its arguments will share symbol names even though the values are different. Prior to this fix the bug409 test would hit a case with 6g where an LEAQ instruction was incorrectly eliminated from the second inlined function call. 8g appears to have had the same bug, but the test did not fail there.

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.
