Using qemu with gcc/gdb testsuites

[David Fernandez]

Hi there,

I'm wondering if it is possible to use qemu as an arm-sim when running
gcc or gdb testsuites form an arm-eabi cross-compiler.

I've found some examples on running a bare metal program with:

    qemu-system-arm -cpu cortex-m3 -nographic -monitor null -serial null
-semihosting -kernel <myprogram>

The problem is that I know nothing about dejagnu, and I wonder what is
the easiest way to make everything work together, as the dejagnu
documentation is a bit dense.

Could any of you give me a quick recipe?

Do I need to compile a linux arm kernel to use qemu as a remote
simulator for testing? Could it be run using semihosting like the
example above?

Cheers
