# The second and third ADR instructions are non-local to functions
# and must be replaced with ADRP + ADD by BOLT
# Also since main is non-simple, we can't change it's length so we have to
# replace NOP with adrp, and if there is no nop before adr in non-simple
# function, we can't guarantee we didn't break possible jump tables, so we
# fail in strict mode
