Some functions are used by code adding markers, and require adding ifdef around this code, which is annoying (and error prone).
As discussed in bug 1635350, I think adding some inline functions returning false in ProfilerState.h would simplify the code adding markers.

In the network code, we use profiler_can_accept_markers to avoid doing expensive work when recording markers, it would be a good idea to return false when the profiler isn't compiled in. I believe that this alone would avoid using the ifdef in that code.
(update: I would also need a noop for the adding marker functions)

In the network code, we use
profiler_can_accept_markersto avoid doing expensive work when recording markers, it would be a good idea to return false when the profiler isn't compiled in. I believe that this alone would avoid using theifdefin that code.
My hope is that this simple patch alone should be enough to let us remove most MOZ_GECKO_PROFILER ifdefs that are outside of tools/profiler and mozglue/baseprofiler.
(update: I would also need a noop for the adding marker functions)
I mentioned in my review of https://phabricator.services.mozilla.com/D104587 that profiler_add_network_marker should be moved out of GeckoProfiler.h, to be somewhere in netwerk/protocol/http/. Hopefully it can call a marker API that always exists and is a no-op when the profiler isn't built (that probably just means using the PROFILER_MARKER macro instead of calling profiler_add_marker directly.
Gerald opened bug 1692929 for the follow-ups to that patch.
