Hi Gunther,

Thanks for such a handy utility. I'm using SXSim 2.07 to check the speed of code that I'm hoping to move from user space to ISR space, and it's working great. 

But...

I have code that includes a macro. When I run it in SXSim, the macro is not expanded. When I single-step through the code to execute at the location of the macro, an incorrect instruction is listed, although the code cyclecounts and elapsed time do perform correctly. 

Is this part of the SXSIM design? 

I was hoping the macros would be expanded in the resulting code. Is my expectation unrealistic for some reason? I've searched the documentation and haven't seen any mention about how macros are (or aren't) treated.

Example code is shown below. In the example, I manually inserted the macro contents in one place to show that SXSim is performing the same cyclecounts for the macro code vs the actual code.
