Hello,
Am a beginner with marss. In the following stats I had fixed the
configuration file as
-machine single_core
-stats hello.stats
-corefreq 2000000000
-time-stats-logfile time_stats.csv
-time-stats-period 100000
and got the below log.
Start logging at level 0 in cycle 0

Invalid opcode at 0x7f247eff3059: split_invalid_basic_blocks 0,
first_insn_in_bb? 1
My Questions:
1. Why is the frequency of the processor changing when I have fixed it?
2. How are the invalid opcode handled?
3. Am not able to generate -time-stats-period logfile for an atom core
configuration should I modify the atomcore.cpp fot this?
