Great!

Could you try something like:

# perf record some_workload
# perf annotate --stdio2 hot_function

So that we can see this thing in action, i.e. sparc assembly annotated?
:-)

With 'perf annotate --tui hot_function' or 'perf top' 'A' you can
navigate, but for showing it in action in a git changelog comment
example --stdio is more convenient :-)

Sure :-)

This is run on __gettimeofday when running perf record on your "gtod"
test.  (Still working on getting glibc to use the VDSO properly on
sparc :-( )

Samples: 7K of event 'cycles:ppp', 4000 Hz, Event count (approx.): 3086733887
