Subject: [PATCH 08/15] perf script: Mark inlined frames and do not print DSO for them
Date: Wed, 25 Oct 2017 13:00:06 -0300 [thread overview]
Message-ID: <20171025160013.11136-9-acme@kernel.org> (raw)
In-Reply-To: <20171025160013.11136-1-acme@kernel.org>
From: Milian Wolff <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)
