I think we should also mention the step where the profile is collected and applied to the IR (which was then reduced)? I see the metadata has InstrProf so we should mention that here too.

@kazutakahirata I think here a text format profile would have helped significantly. The other profiles mixed in already have text formats so just because memprof doesn't it makes constructing the test even more tedious.
