That I forgot to mention: INITIAL_FRAME_POINTER_OFFSET is just a single call, so whenever it is called from lra/reload the frame layout is really expected to change, and so it does not make a difference if the t= arget computes the frame layout in TARGET_COMPUTE_FRAME_LAYOUT or in INITIAL_FRAME_POINTER_OFFSET. But I do not know of any targets that still use INITIAL_FRAME_POINTER_OFFSE= T, and maybe support for this target hook could be discontinued as a follow-up= patch. What do you think? Bernd.
