Yes. Or, well, you might also need to specify it when linking. > I seem to recall we had some hack to actually get each backend's gmon.out to > not step on each other's which needed an explicit flag to enable? I think that's enabled by default in gcc these days, if supported by the platform? TBH, I really don't see the point of this style of profiling. It doesn't provide an accurate view of where time is spent. You're much better off using performance counter driven profiling with perf et al. Greetings, Andres Freund
