ST marketing materials put STM8 Dhrystone performance at 0.29 DMIPS / Mhz.
However, when actually compiling the Dhrystone benchmark with different
C compilers optimizing for speed, the picture is a bit different:
Raisonance is at 0.289 DMIPS / Mhz and Cosmic at 0.296 DMIPS / Mhz, both
very close
Hi Philipp,
thank you for the good work ! All regression tests are OK ?

Regression tests pass. The Dhrystone self-test passes.
However, I have to admit, that to achieve this, I closely looked at what
SDCC does for Dhrystone and f
Here's a graphical representation of how SDCC compares to other
compilers at Dhrystone.

Sorry, attached the worng picture for the code size before. Here's the
correct one.
