+   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.  */
