43 /* The main purpose of this file is dealing with prologues to extract
44 information about stack frames and saved registers.
46 For reference here's how prologues look on the mn10200:
52 Register saves for d2, d3, a1, a2 as needed. Saves start
53 at fp - <size> + <outgoing_args_size> and work towards higher
54 addresses. Note that the saves are actually done off the stack
55 pointer in the prologue! This makes for smaller code and easier
56 prologue scanning as the displacement fields will unlikely
59 Without frame pointer:
61 Register saves for d2, d3, a1, a2 as needed. Saves start
62 at sp + <outgoing_args_size> and work towards higher addresses.
65 add <local size>,sp -- optional
67 add <outgoing_size>,sp -- optional
69 The stack pointer remains constant throughout the life of most
70 functions. As a result the compiler will usually omit the
71 frame pointer, so we must handle frame pointerless functions. */
73 /* Analyze the prologue to determine where registers are saved,
74 the end of the prologue, etc etc. Return the end of the prologue
77 We store into FI (if non-null) several tidbits of information:
79 * stack_size -- size of this stack frame. Note that if we stop in
80 certain parts of the prologue/epilogue we may claim the size of the
81 current frame is zero. This happens when the current frame has
82 not been allocated yet or has already been deallocated.
84 * fsr -- Addresses of registers saved in the stack by this frame.
86 * status -- A (relatively) generic status indicator. It's a bitmask
87 with the following bits:
89 MY_FRAME_IN_SP: The base of the current frame is actually in
90 the stack pointer. This can happen for frame pointerless
91 functions, or cases where we're stopped in the prologue/epilogue
92 itself. For these cases mn10200_analyze_prologue will need up
93 update fi->frame before returning or analyzing the register
96 MY_FRAME_IN_FP: The base of the current frame is in the
97 frame pointer register ($a2).
99 CALLER_A2_IN_A0: $a2 from the caller's frame is temporarily
100 in $a0. This can happen if we're stopped in the prologue.
102 NO_MORE_FRAMES: Set this if the current frame is "start" or
103 if the first instruction looks like mov <imm>,sp. This tells
104 frame chain to not bother trying to unwind past this frame. */
