# The target (below) defaults to cortex-m4
# There currently are two different options to go beyond that:
# 1. cortex-m7 has the right flags and instructions (FPU) but no instruction schedule yet
"-C", "target-cpu=cortex-m7",
# "-C", "target-cpu=cortex-m7",
# 2. cortex-m4 with the additional fpv5 instructions and a potentially
# better-than-nothing instruction schedule
