m4_dnl These are utility macros for use with delays. Specifically, there is code below which needs some predictability in code size for relative jumps to reach. The m4_delay macro generates an extra NOP when an even delay is needed, and the m4_delay_loop macro generates an extra NOP when an odd delay is needed. Using this for the argument to the respective macro rounds up the argument so that the extra NOP will not be generated. There is also logic built in to cancel the rounding when the result is small enough that a loop would not be generated.
