| |
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)
