#Compiler optimize settings:
# -O0 no optimize, reduce compilation time and make debugging produce the expected results (default).
# -O1 optimize, reduce code size and execution time, without much increase of compilation time.
# -O2 optimize, reduce code execution time compared to ‘O1’, increase of compilation time.
# -O3 optimize, turns on all optimizations, further increase of compilation time.
# -Os optimize for size, enables all ‘-O2’ optimizations that do not typically increase code size and other code size optimizations.
# default settings for release version: COMMONFLAGS=-O3 -g -mcpu=cortex-m3 -mthumb
# default settings for debug version: COMMONFLAGS=-O0 -g -mcpu=cortex-m3 -mthumb
