Here's a first reuslt from an ARM Cortex-M0 (the STM32F051R8 at 48 Mhz)
compiled using GCC 6.3.1 with -O2 and using newlib-nano:

stdcbench 0.3
stdcbench c90base score: 1141
stdcbench c90lib score: 651
stdcbench final score: 1792

Per clock cycle, this Cortex-M0 with GCC gets about twice the score
compared to an STM8 with IAR.
Interesting is the large difference between the c90base and the c90lib
score. I guess newlib-nanao is optimized for code size at the expense of
speed (even though it is surprising to see that much of a difference vs.
the situation for the STM8).
