Which targets do not? You should explicitly list them and CC their maintainers and seek confirmation that such a change is appropriate for them. The addition of -fomit-frame-pointer through this mechanism was a replacement for the old target macro CAN_DEBUG_WITHOUT_FP. It may now be the cases that with DWARF debug info, having or not having a frame pointer is not particularly relevant to debugging. But since there are other reasons people may want a frame pointer (e.g. light-weight backtraces that don't depend on debug / unwind info), it's at least possible there are architecture-specific choices regarding keeping frame pointers involved here. -- Joseph S.
