If the address belongs to an inlined function, the source information
back to the first non-inlined function will be printed.
For example:
perf report --stdio --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)
