-/**
- * Simple naive instrumentation on (x86) assembler files
- * @author Matthias Braun (warning this is a 30 minutes hack and no nice code!)
- *
- * Takes an assembler file and adds instrumentation code to some instructions.
- * You have to link the output with saveinstr.c
- *
- * Example usage with a file queens.s:
- *
- *    (adapt is_instr function here to your needs and compile instrument.cpp)
- *    instrument < queens.s > queensi.s
- *    gcc queensi.s saveinstr.c -o queensi
- *    ./queensi     	(run with you desired arguments and testdata)
- *    instrument -a < queens.s > queens_annotated.s
- *    You will get a list of the hottest spots in your file and an assembler
- *    will the instructions prefixed with their execution count
