/* DEPRECATED_FRAME_CHAIN takes a frame's nominal address and produces
the frame's chain-pointer. */
-/* In the case of the Sun 4, the frame-chain's nominal address
- is held in the frame pointer register.
-
- On the Sun4, the frame (in %fp) is %sp for the previous frame.
- From the previous frame's %sp, we can find the previous frame's
- %fp: it is in the save area just above the previous frame's %sp.
-
- If we are setting up an arbitrary frame, we'll need to know where
- it ends. Hence the following. This part of the frame cache
- structure should be checked before it is assumed that this frame's
- bottom is in the stack pointer.
-
- If there isn't a frame below this one, the bottom of this frame is
- in the stack pointer.
-
- If there is a frame below this one, and the frame pointers are
- identical, it's a leaf frame and the bottoms are the same also.
-
- Otherwise the bottom of this frame is the top of the next frame.
-
- The bottom field is misnamed, since it might imply that memory from
- bottom to frame contains this frame. That need not be true if
- stack frames are allocated in different segments (e.g. some on a
- stack, some on a heap in the data segment).
-
- GCC 2.6 and later can generate ``flat register window'' code that
- makes frames by explicitly saving those registers that need to be
- saved. %i7 is used as the frame pointer, and the frame is laid out
- so that flat and non-flat calls can be intermixed freely within a
- program. Unfortunately for GDB, this means it must detect and
- record the flatness of frames.
-
- Since the prologue in a flat frame also tells us where fp and pc
- have been stashed (the frame is of variable size, so their location
- is not fixed), it's convenient to record them in the frame info. */
