| H A D | unwind.h | diff 6bcdf9d51b9892dd5c6892d50cf5e9628efb8062 Wed Apr 12 13:47:11 CDT 2017 Josh Poimboeuf <jpoimboe@redhat.com> x86/unwind: Read stack return address in update_stack_state()
Instead of reading the return address when unwind_get_return_address()
is called, read it from update_stack_state() and store it in the unwind
state. This enables the next patch to check the return address from
unwind_next_frame() so it can detect an entry code frame.
