Hello,
We did all the measurements for the three implementations of the operation using the logic analyzer and a performance counter without problems. However, when we try using the GNU profiler, we get a weird behaviour.
It usually runs the program until the end, and starts uploading the GMON data, but at a random percentage of the upload, it crashes.
Here is the command we use to run the code:
make all && nios2-download -g --write-gmon gmon_0.out *.elf && nios2-elf-gprof *.elf gmon_0.out > report_0.txt
It sometimes works, but even then, the results are not always coherent. Either the timings are similar to our previous measurements, either the time is 0 (we even sometimes cannot find some functions we call in the report).
Thank you for your help,
Sacha
