[PATCH ARM]: Architectural Extensions (Matthew Gretton-Dann or Richard Earnshaw)

[David Fernandez <david dot fernandez dot work at googlemail dot com>]

Hi there Matthew Gretton-Dann, or Richard Earnshaw, or anybody that
knows about this...

I moved from cortex-m3 to cortex-r4, just to discover that the
assembler seems to know nothing about banked registers, SRS/RTE
instructions and the like, which is worrying, as these AFAIK are basic
features for armv7-r/a architectures without any security or
virtualization extensions.

Then I came around these posts that seem to imply that all this stuff
is suported as pasrt of the "virt" extension for the armv7-a
architecture. Am I right so far?

So, if that is the case, Do you have apropriate patches like these in
some ftp for latest binutils 2.23.1?

Otherwise, how can I make the binutils to recognize this stuff?

I'll appreciate a quick answer, although I understand that, so close
to holidays might make people to not read this list at all... :)

Regards.
David Fernandez
