I've profiled a C++ application using GNU gprof. It would be really nice to visualize the data and for that purpose I found a python utility gprof2dot, which creates a graph from the gprof data, nice! But, ultimately I'd like to visualize the data as a flamegraph, popularized by Brendan Gregg. However, to my big surprise, I've not been able to find a tool to convert the gprof data into a format that flamegraph understands!?
Is anyone aware of such a utility? Or know how to do a workaround?
How do one visualize gprof profiling data as a flamegraph?
