Interworking is a madatory of the ARM EABI. As mentioned above, interworking is basically free on armv5 and later architectures. It should never be disabled. > The gcc docs seem to agree with my understanding. Not realy. Most of the gcc options relating to interworking only apply to legacy targets (i.e. pre-eabi).
