I would recommend first fixing latest mintlib symbols [1] and then
profiling binary built with it in Hatari (v1.7 or devel version).
Here are instructions:

Note that I haven't tried profiling things running under MiNT,
just under TOS [2].  Profiling C++ programs requires running
results through c++filt, as profiler itself doesn't do symbol
name demangling.

[2] E.g. Douglas' Doom I/II port/rewrite which nowadays runs at playable
    speed on Falcon and has some additional gfx features compared to
    original Doom (mipmapping, 16-bit gfx).
