--- Comment #7 from Christian Hergert <chergert at redhat dot com> --- (In reply to Andrew Pinski from comment #3) > Also on x86_64, frame pointers are not required by the ABI so this is not an > ABI issue. Why instead are you not using the dwarf2 unwind tables that are > generated by default too? Because the stack unwinding comes from the Linux kernel, which the default unwinder can only support frame-pointers. The DWARF unwinder was removed long ago. Additionally, it can't use `.eh_frame_hdr` either.
