It is difficult to satisfy everyone. We no longer inline delay_wait_us on i386, ARM should behave the same. For whatever reason we still inline delay_wait_us_ms. I am checking why. Size is estimated to grow by one instruction (that is bit underestimated) but with --param early-inlining-insns=0 we should not inline. Honza
