Good afternoon, We are currently using callgrind on Centos Linux 5.5
x86_32 to profile an entire program using the
command:/home/frankc/DQTTest2/valgrind-3.6.1/coregrind/valgrind
--tool=callgrind --dump-instr=yes --simulate-cache=yes
--collect-jumps=yes ./MatchUpAccurate.exe
We were wondering whether Is it possible for callgrind to
selectively profile certain periods of our program's execution? We
understand there is callgrind tool : 1. callgrind_control -i on 2.
callgrind_control -i off that may allow us to profile certain periods
of a program's execution.
However, we uncertain which callgrind options we should use to
accomplish this requirement . So far we think we need to use:
:/home/frankc/DQTTest2/valgrind-3.6.1/coregrind/valgrind
--tool=callgrind -instr-atstart=no ????. Could any valgrind users or
engineers tell us how to use the --instr-atstart=no option with our
program ./MatchUpAccurate.exe? Thank you.
