use valgrind to know time(in seconds) spent in each function

Question

is there any extension of valgrind, that can be used in the command window, that would help me know the time, in seconds, spent in each function in my C code?

thanks =)

Answer 1

For machine instruction profiling use valgrind's callgrind (also, cachegrind can do cache and branch prediction profiling which is quite nice).

For time measurements use google's cpu profiler, it gives way better results than gprof. You can set sampling frequency and it can show the output as a nice annotated call graph.
