Claudiu,

Thanks for the reply.  Maybe I was not clear.  I was asking for an
example of a backend which operates in a manor similar to your
proposed patch for ARC.

The ARM example you give does not appear, at a first glance to be
similar.

Your patch picks one sub-set of instructions based on the first
instruction it finds, ARM selects the sub-set based on symbol type
information.  The command line flag allows override for cases were (I
guess) users are doing non-standard things with symbols.

Maybe you could explain in a little more detail why you think the ARM
code is similar, or maybe there's another backend which is more
similar to ARC in its algorithm?

Thanks,
Andrew
