Does arm-none-eabi-gdb support simulator

Asked by Murat Belge

Does the GDB debugger, arm-none-eabi-gdb, support simulator target? I was able to run a remote debugging session using the GDB and QEMU for an ARM Cortex M3 CPU. I would like to do the same for ARM Cortex M4F processor. QEMU has not support for CPU's other than Cortex M3. "target sim" command in the GDB debugger results in "undefined command" error.

If the simulator is not supported, is there plans to do so in a future release?

It is in the release.txt we said the sim in gdb is excluded from our release and won't be included at least in the near future, because we think the sim is feeble and not as useful as thought. For example, I doubt the instructions of Cortex M4F is supported (I may be wrong about this, please correct then).
Thanks very much.
