/*
* FRAME is the type of the identifier of a specific stack frame. It
* is a pointer to the frame cache item corresponding to this frame.
* Please note that frame id's are *not* constant over calls to the
* inferior. Use frame addresses, which are.
*
* FRAME_ADDR is the type of the address of a specific frame. I
* cannot imagine a case in which this would not be CORE_ADDR, so
* maybe it's silly to give it it's own type. Life's rough.
*
* FRAME_FP is a macro which converts from a frame identifier into a
* frame_address.
*
* FRAME_INFO_ID is a macro which "converts" from a frame info pointer
* to a frame id. This is here in case I or someone else decides to
* change the FRAME type again.
*
* This file and blockframe.c are the only places which are allowed to
* use the equivalence between FRAME and struct frame_info *. EXCEPTION:
* value.h uses CORE_ADDR instead of FRAME_ADDR because the compiler
* will accept that in the absense of this file.
