Show SDT and pre-cached events by perf-list with "sdt". This also shows
the binary and build-id where the events are placed only when there are
same name events on different binaries.
e.g.:
# perf list sdt
List of pre-defined events (to be used in -e):
sdt_libc:lll_futex_wake [SDT event]
sdt_libc:lll_lock_wait_private [SDT event]
sdt_libc:longjmp [SDT event]
sdt_libc:longjmp_target [SDT event]
...
sdt_libstdcxx:rethrow@/usr/bin/gcc(0cc207fc4b27) [SDT event]
sdt_libstdcxx:rethrow@/usr/lib64/libstdc++.so.6.0.20(91c7a88fdf49)
sdt_libstdcxx:throw@/usr/bin/gcc(0cc207fc4b27) [SDT event]
sdt_libstdcxx:throw@/usr/lib64/libstdc++.so.6.0.20(91c7a88fdf49)
The binary path and build-id are shown in below format;
<GROUP>:<EVENT>@<PATH>(<BUILD-ID>)
