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 :-( )
