template <class AbiTraits = LocalAbiTraits>struct RDebug
Defined at line 46 of file ../../src/lib/elfldltl/include/lib/elfldltl/svr4-abi.h
This is the traditional `struct r_debug` that SVR4 and other systems declare
in
<link
.h>. In the original scheme, the DT_DEBUG element in the PT_DYNAMIC
(.dynamic) data would be updated to point to this in memory so that a
debugger could examine that in memory to find it. However, debuggers also
began looking for known symbol names like `_r_debug` in the dynamic linker
to find this, so the de facto expectation is that it has that symbol. The
scheme of modifying DT_DEBUG is not feasible when .dynamic is read-only, so
it's not used on systems like Fuchsia with `-z rodynamic` on by default.
