Well, now... :-)

The *Mikroelektronika* code generator is (probably)
not doing anything wrong!

But it generates code for *MikroC*, the compiler from
*Mikroelektronika*, of course!

Why should *they* generate code for the XC8 compiler!?

Is there any specific reson you are using a code generator
for another compiler!? This might also be the reason I was
not sure from the start what compiler you used. :-)

I expect the *stopwatch* in the simulator in MPLAB X to
count cycles based on the generated assembler code.
That has very little to do with XC8 as such.

Can you be more specific on what "calculator"
you are talking about ?

Jan-Erik.
