Subject[PATCH V2 0/9] perf symbols: Improve dso__synthesize_plt_symbols() for x86
Date
Hi

This is version 2 of 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.


Changes in V2:

perf symbols: Add support for x86 .plt.sec
Amend commit message and example about -z plt

perf symbols: Get symbols for .plt.got for x86-64
Fix get_plt_got_name() not to segfault with EM_386


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
