assembler rtn called from C

erik malund

I have the impression that an assembler non-interrupt subroutine called from 'C' need save no registers.

Is that correct?

    Excuse me, your rephrase seems even less clear than the original question. You say: "Are there any cases ... where not saving will topple the code." Should that be understood as "Can an example be constucted..."? If so, the answer is evidently YES. Everything is possible in an assembler routine. If you speak of some practical cases - all depends on your style and skill.
