I looked, is there a _push_(U8 var) to use in C without reverting to inline asm, there is the _nop_() in intrins.h there should be a _push_() and _pop_() as well.
I have ZERO interest in using inlime assembler which I know would solve this. I want to see the C source in the emulator.

Surely, the last thing you want is user code doing PUSH and POP inside a 'C' function?!
actually there are cases
push IE clear EA .... .... pop IE
instead of U8 IEsave; ... IEsave = IE; EA = 0; .... .... IE = IEsave;
and specifically for the SILabs chips
push SFRPAGE SFRPAGE = ..; .... .... pop SFRPAGE
push IE clear EA .... // How can you be sure the compiler doesn't PUSH something here...?? .... pop IE
good point - especially re portability. The one Keil 'trap' I can see is if you are one of those that pass umpteen parametres to a function.
Oh, well, nice thought - bubble burested
Another interesting thing with push/pop in C/C++ code (where the caller is responsible for popping any parameters after a call) is that a compiler can make many function calls before finally shrinking the stack. Such code would not like an intrinsic push/pop directly used by the user code.
This isn't of course not too common in the embedded world, because a lot of hw doesn't the required stack space.
