The in-tree compiler currently is gcc/binutils, which we use for all
ARM builds. I don't know if it has the newer ARM instructions for the
OMAP3530.

No. You have to read the source to get this information at the

Most of the work is in head. However, there's some still straggling
in from the p4 //depot/projects/arm tree and I think we may have
created a base/projects/arm tree in svn as well, but I'm not sure
about that.
