-/* The main purpose of this file is dealing with prologues to extract
-   information about stack frames and saved registers.
-
-   For reference here's how prologues look on the mn10300:
-
-     With frame pointer:
-	movm [d2,d3,a2,a3],sp
-	mov sp,a3
-	add <size>,sp
-
-     Without frame pointer:
-	movm [d2,d3,a2,a3],sp (if needed)
-        add <size>,sp
-
-   One day we might keep the stack pointer constant, that won't
-   change the code for prologues, but it will make the frame
-   pointerless case much more common.  */
-	
-/* Analyze the prologue to determine where registers are saved,
-   the end of the prologue, etc etc.  Return the end of the prologue
-   scanned.
-
-   We store into FI (if non-null) several tidbits of information:
-
-    * stack_size -- size of this stack frame.  Note that if we stop in
-    certain parts of the prologue/epilogue we may claim the size of the
-    current frame is zero.  This happens when the current frame has
-    not been allocated yet or has already been deallocated.
-
-    * fsr -- Addresses of registers saved in the stack by this frame.
-
-    * status -- A (relatively) generic status indicator.  It's a bitmask
-    with the following bits: 
-
-      MY_FRAME_IN_SP: The base of the current frame is actually in
-      the stack pointer.  This can happen for frame pointerless
-      functions, or cases where we're stopped in the prologue/epilogue
-      itself.  For these cases mn10300_analyze_prologue will need up
-      update fi->frame before returning or analyzing the register
-      save instructions.
-
-      MY_FRAME_IN_FP: The base of the current frame is in the
-      frame pointer register ($a2).
-
-      NO_MORE_FRAMES: Set this if the current frame is "start" or
-      if the first instruction looks like mov <imm>,sp.  This tells
-      frame chain to not bother trying to unwind past this frame.  */
