Is ARMv7-M3 thumb instructions compatible to ARMv7-A thumb?

Kaiyuan

Hello guys,

I am trying to verify some features of ARMv7-M3 in a software simulator platform for ARM. But this simulator only support ARMv7-A ISA.

Is ARMv7-M3 instructions compatible to ARMv7-A, especially thumb instructions?

Thank you very much.
