Subject: [PATCH 0/9] perf symbols: Improve dso__synthesize_plt_symbols() for x86
Date: Fri, 27 Jan 2023 19:02:13 +0200 [thread overview]
Message-ID: <20230127170222.9895-1-adrian.hunter@intel.com> (raw)
Hi
This is the second of 2 patchsets to improve dso__synthesize_plt_symbols().
This patchset focuses on getting rid of unknown symbols that show up in
Intel PT traces.
x86 has 2 more plt's, namely .plt.sec and .plt.got, so support is added for
synthesizing symbols for them. Special handing is needed for IFUNC symbols,
and it is also possible to have a .plt for static executables, so support is
added for that.
Adrian Hunter (9):
perf symbols: Correct plt entry sizes for x86
perf symbols: Add support for x86 .plt.sec
perf symbols: Sort plt relocations for x86
perf symbols: Record whether a symbol is an alias for an IFUNC symbol
perf symbols: Add support for IFUNC symbols for x86_64
perf symbols: Allow for .plt without header
perf symbols: Allow for static executables with .plt
perf symbols: Start adding support for .plt.got for x86
perf symbols: Get symbols for .plt.got for x86-64
