The function x86-64-tdep.c:x86_64_frame_p() should contain:
return x86_64_unwind;

The file/function dwarf2cfi-frame.c:dwarf2cfi_frame_p() should contain:
if (cfi_have_unwind_info (pc))
return dwarf2cfi_unwind;

(Assuming sigtramps are os specific) The file/function
x86-64-linux-tdep.c:x86_64_linux_sigtramp_frame_p() should contain:
> if (gdbarch_pc_in_sigtramp (current_gdbarch, pc, name))
