I think there's some confusion here. ILT means DWARF /debug/ info[1] (the other kind of debug info supported by GCC is STABS (there's also COFF, VMS and variations, not our concern though); gcc uses DWARF by default, gdb understands both), not DWARF (DW2) exception handling (where the other exception handling mechanism is SJLJ, for 32-bit programs, and 64-bit programs have their own, 64-bit-specific exception handling).
