When libbfd is not used, it doesn't show proper function name and reuse
the original symbol of the sample. That's because it passes the
original sym to inline_list__append(). As `addr2line -f` returns
function names as well, use that to create an inline_sym and pass it to
inline_list__append().
For example, following data shows that inlined entries of main have same
name (main).
Before:
$ perf report -g srcline -q | head
45.22% inlining libm-2.26.so [.] __hypot_finite
|
---__hypot_finite ??:0
|
|--44.15%--hypot ??:0
| main complex:589
| main complex:597
| main complex:654
| main complex:664
| main inlining.cpp:14
After:
$ perf report -g srcline -q | head
45.22% inlining libm-2.26.so [.] __hypot_finite
|
---__hypot_finite
|
|--44.15%--hypot
| std::__complex_abs complex:589 (inlined)
| std::abs<double> complex:597 (inlined)
| std::_Norm_helper<true>::_S_do_it<double> complex:654 (inlined)
| std::norm<double> complex:664 (inlined)

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
