Subject: [PATCH v4 08/15] perf script: mark inlined frames and do not print DSO for them
Date: Sun, 1 Oct 2017 16:30:53 +0200 [thread overview]
Message-ID: <20171001143100.19988-9-milian.wolff@kdab.com> (raw)
In-Reply-To: <20171001143100.19988-1-milian.wolff@kdab.com>
Instead of showing the (repeated) DSO name of the non-inlined
frame, we now show the "(inlined)" suffix instead.
Before:
214f7 __hypot_finite (/usr/lib/libm-2.25.so)
ace3 hypot (/usr/lib/libm-2.25.so)
a4a std::__complex_abs (/home/milian/projects/src/perf-tests/inlining)
a4a std::abs<double> (/home/milian/projects/src/perf-tests/inlining)
a4a std::_Norm_helper<true>::_S_do_it<double> (/home/milian/projects/src/perf-tests/inlining)
a4a std::norm<double> (/home/milian/projects/src/perf-tests/inlining)
a4a main (/home/milian/projects/src/perf-tests/inlining)
20510 __libc_start_main (/usr/lib/libc-2.25.so)
bd9 _start (/home/milian/projects/src/perf-tests/inlining)
After:
214f7 __hypot_finite (/usr/lib/libm-2.25.so)
ace3 hypot (/usr/lib/libm-2.25.so)
a4a std::__complex_abs (inlined)
a4a std::abs<double> (inlined)
a4a std::_Norm_helper<true>::_S_do_it<double> (inlined)
a4a std::norm<double> (inlined)
a4a main (/home/milian/projects/src/perf-tests/inlining)
20510 __libc_start_main (/usr/lib/libc-2.25.so)
bd9 _start (/home/milian/projects/src/perf-tests/inlining)
