If the address belongs to an inlined function, the source information
back to the first non-inlined function will be printed.
For example:
1. Show inlined function name
perf report --stdio -g function --inline
0.69% 0.00% inline ld-2.23.so [.] dl_main
|
---dl_main
|
--0.56%--_dl_relocate_object
_dl_relocate_object (inline)
elf_dynamic_do_Rela (inline)
2. Show the file/line information
perf report --stdio -g address --inline
0.69% 0.00% inline ld-2.23.so [.] _dl_start_user
|
---_dl_start_user .:0
_dl_start rtld.c:307
/build/glibc-GKVZIf/glibc-2.23/elf/rtld.c:413 (inline)
_dl_sysdep_start dl-sysdep.c:250
