CppCon 2018: Serge Guelton “C++ in Elvenland”

—
—
On Linux systems, compiled C++ code is generally bundled in the ELF binary
format. This talk walks through several details of the format that can help a
C++ developper to better understand the whole compilation chain, from classical
text and data sections through symbol tables down to init_array, eh_frame.

The talk walks though all the sections of a binary compiled from a simple C++
code and explain the links between c++ concepts like constant global variables,
exceptions, global constructors, ODR, symbol visibility, thread local variables
and related binary artefacts.

All these aspects will be demonstrated on a live demo using the output of the
venerable objdump and readelf commands.
