For now I have...
const struct frame_unwind * x86_64_frame_p (CORE_ADDR pc) { struct frame_unwind *unwind_cfi = NULL; struct frame_unwind *unwind_asm = &x86_64_asm_frame_unwind; struct frame_unwind *unwind_sigtramp = &x86_64_sigtramp_frame_unwind; char *name;
find_pc_partial_function (pc, &name, NULL, NULL); if (gdbarch_pc_in_sigtramp (current_gdbarch, pc, name)) return unwind_sigtramp; else if (cfi_have_unwind_info (pc)) return unwind_cfi; /* Returns NULL here... */ else return unwind_asm; }
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;
