Rosetta is software component (feature) by Apple that allowed programs written for PowerPC machines to run on Intel machines when Apple switched between the two CPUs in 2006. It gave software vendors enough time to transition their software to ( retarget) Intel. In other words, Rosetta is a dynamic binary translator ( interpreter) that acts as an application compatibility layer between different instructon sets (machine languages). On a side note, Apple has started to use Rosetta 2 to help in their transition from Intel chips to Apple Silicon, their new chip. Using T-diagrams only, show how we managed to run a sorting program that was written for PowerPC-based Mac on Intel-based Mac. In your diagram show everything like in the extra slides on T-diagrams.

The GCC compiler has an option to generate assembly rather than machine code, namely the -S flag. Create a small program in C to determine if gcc performs the two techniques above. Your answer must include: 1. The source code in C. 2. If gcc performs constant folding with an evidence from the assembly code. 3. If gcc performs constant propagation with an evidence from the assembly code.
