Is there a way to prevent GCC from generating null reference function pointers ? In fact, the target to which I ported GCC always generate position-independent-code; so it is not always loaded at the address specified in the ELF header, and that is where I run into issues with the way GCC implement null reference function pointers. For example in crtstuff.c, there is a null reference function pointer check on __register_frame_info() within frame_dummy(); if the executable is not loaded at the address specified in the ELF header, the check on __register_frame_info() is never null when it is supposed to be null. Is there a way to prevent GCC from generating null reference function pointers ?
