Help¶

Choose Y for best performance. On some architectures (including x86) this will favor code size and performance over debugability.

Choose N in you wish to retain the frame pointer. This option may be useful if your application uses runtime backtracing and does not support parsing unwind tables.

If unsure, disable OVERRIDE_FRAME_POINTER_DEFAULT to allow the compiler to adopt sensible defaults for your architecture.

Direct dependencies¶

OVERRIDE_FRAME_POINTER_DEFAULT

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
