hm, -l doesnt work so well if a user-space binary (in this case the
'git' binary of the Git project) is profiled:
aldebaran:~/git> perf record -f ./git gc
Counting objects: 1148, done.
Delta compression using up to 16 threads.
Compressing objects: 100% (450/450), done.
Writing objects: 100% (1148/1148), done.
Total 1148 (delta 690), reused 1148 (delta 690)
[ perf record: Captured and wrote 1.649 MB perf.data (~72032 samples) ]
aldebaran:~/git> perf annotate -l lookup_object
