Here is a Cortex-M4 (the STM32F302R8 at 64 Mhz - it could do 72 Mhz, but
not with the internal oscillator, and my board doesn't have a crystal),
using GCC -O2 -mcpu=cortex-m4 -mthumb with newlib-nano:

stdcbench 0.3
stdcbench c90base score: 1693
stdcbench c90lib score: 864
stdcbench final score: 2557

Looks only 15% faster per clock cycle than the Cortex-M0.
