Hi Andre,

Hello,
After some changes to GCC this test no longer tests the desired code
generation behavior. The generated assembly is better than it used to
be, but it has become too smart. I add an extra parameter to make sure
GCC can't optimize away the loop.
Tested for arm-none-eabi-gcc with a Cortex-M3 target.
Is this OK?
Ok if this passes on an A-profile target as well (-march=armv7-a or some such).
Sorry for missing this.
Thanks,
Kyrill
Cheers,
Andre
