The Go programming language

The new src argument is ignored during linking (that is, CALL r1, r2 is identical to CALL r2 for linking), but it serves as a hint to the 5g/6g/8g optimizer that the src register is live on entry to the called function and must be preserved. It is possible to avoid exposing this fact to the rest of the toolchain, keeping it entirely within 5g/6g/8g, but I think it will help to be able to look in object files and assembly listings and linker -a / -W output to see CALL instructions are "Go func value" calls and which are "C function pointer" calls.

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.
