Module std::source ·
This module contains the implementation of the
eh_personality lang item.
The actual implementation is heavily dependent on the target since Rust tries to use the native stack unwinding mechanism whenever possible.
This personality function is still required with
-C panic=abort because
it is used to catch foreign exceptions from
extern "C-unwind" and turn
them into aborts.
Additionally, ARM EHABI uses the personality function when generating backtraces.

- gcc 🔒Implementation of panics backed by libgcc/libunwind (in some form).
