[dev.cc] all: edit assembly source for ARM to be more regular Several .s files for ARM had several properties the new assembler will not support. These include: - mentioning SP or PC as a hardware register These are always pseudo-registers except that in some contexts they're not, and it's confusing because the context should not affect which register you mean. Change the references to the hardware registers to be explicit: R13 for SP, R15 for PC. - constant creation using assignment The files say a=b when they could instead say #define a b. There is no reason to have both mechanisms. - R(0) to refer to R0. Some macros use this to a great extent. Again, it's easy just to use a #define to rename a register.

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
