Hi, could anyone suggest a good c++ code profiler. I have been using a gprof but now i need something more sensitive. something that can tell me within each function how much time is spend on a particular line of code.
Is there anything out there that can do that?
thnx

Windows? Linux?
I use "Very Sleepy" on Windows, which is a sampling-based profiler. Its very non-invasive, but wont catch everything with 100% accuracy.

What do you mean by "profile lines"?
The actual time executing a single loop iteration is minuscule compared to everything else going on.Code:void foo ( int n ) { for ( int i = 0 ; i < n ; i++ ) { printf("n=%d\n", i ); } }
What might be more interesting is seeing that the loop was executed say 1000 times.
If this is what you're really after, then try gcov
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
gprof will profile lines if you pass the -l option.Originally Posted by baxy
