Byte Craft implemented a embedded library that has delay routines in it
(arguments in us ms ) This library has identical calling sequences for
several compilers. Because the delay is a compiler supported library
code written using the calling conventions is portable over diverse
architectures.

These are strictly delay libraries rather than interleaved delay and
executable code next event. the bigger issue in this thread is how to
generate delays automatically and still be able to use the cycles
for other work by the processor. There are two solutions turn off
interrupts or use timers (with or without interrupts) . Compilers could
track the instruction time, easy with straight line code and more
complex with when branches or loops are involved. It would
probably be trade-off between optimization and exact timing.

I agree with Wouter that as far as I know no C compilers have done
this for embedded systems.
