How would it work to produce small modules of compiled code written in 'C' using, say, KEIL, to produce relocatable modules that can later be linked and loaded together with other modules that are written in ASM?

It seems to me that, while unconventional, it should work.

Could that be done using Keil to produce the relocatable objects and subsequently link them?

I do occasionally run into tasks that are not time-critical, nor particularly size-critical, but which are remarkably easier to understand in 'C' than in ASM. From a documentation standpoint, these would be better written in 'C', though much of the remaining code, because it interacts with hardware features, etc, is best done in ASM.
