perf report: Show inline stack for browser mode
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 -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 -g address --inline
- 0.69% 0.00% inline ld-2.23.so [.] _dl_start
_dl_start rtld.c:307
/build/glibc-GKVZIf/glibc-2.23/elf/rtld.c:413 (inline)
+ _dl_sysdep_start dl-sysdep.c:250
