ARM Cortex M4

Note: This was originally posted on 27th May 2010 at http://forums.arm.com

Hello,
I just wanted to know if the "*.o" file generated by armcc / RVDS giving the option of processor as Cortex M3 is similar if the Cortex M4 were available. I have some code to be run and I was wondering if the Cortex M3 generated files could work with Cortex M4.
If not then in that case is ARMv7 the closest to Cortex M4 (since Cortex documents point to ARMv7 for reference) ?
In that case can I use RVDS to generate the ".o" files for ARMv7 ?
Or do I have to wait till RVDS for Cortex M4 is available ? Is there any GNU compiler which I can use ?

I am exploring the possibility re-using the existing ARM Compiler license for the Cortex M4 to which we plan to upgrade. Any advise / guidance or tips would be helpful.

Regards,
Sarvesh
