Daniel Thompson f9733e492d misc: Let the compiler choose whether to omit frame pointer ... Currently CONFIG_OMIT_FRAME_POINTER is a boolean and defaults to N, which increases code size. This is intended to improve debugability but on many architectures the use of this option does not actually compromise debugging. Further the compiler already knows whether or not omitting the frame pointer is harmful to debugging and its defaults are selected accordingly. By making this choice optional we can have a sane default on *all* architectures by letting the compiler decide for us. This patch significantly improves the default code generation on arm (thumb), nios2 and arc. The benefit looks to be about between 5% and 10% code size reduction depending upon architecture). x86 is unaffected.
