Hi Julian,

ChangeLog (gas):

    * config/tc-arm.c (md_assemble): Improve diagnostic when attempting
    to use ARM instructions on non-ARM-supporting cores.
    (autoselect_thumb_from_cpu_variant): New function. Switch on Thumb
    mode automatically based on cpu variant.
    (md_begin): Call above function.

ChangeLog (gas/testsuite):

    * gas/arm/noarm.s: Add test for disabled ARM insns.
    * gas/arm/noarm.d: Drive test for above.
    * gas/arm/noarm.l: Expected error output.

Approved - please apply.

Cheers
  Nick
