* Clang does not store pc or sp in function prologues so we don't know exactly
* where the function starts.
*
* We can treat the current frame's lr as the saved pc and the preceding
* frame's lr as the current frame's lr, but we can't trace the most recent
* call. Inserting a false stack frame allows us to reference the function
* called last in the stacktrace.
*
* If the call instruction was a bl we can look at the callers branch
* instruction to calculate the saved pc. We can recover the pc in most cases,
* but in cases such as calling function pointers we cannot. In this case,
* default to using the lr. This will be some address in the function, but will
* not be the function start.
*
* Unfortunately due to the stack frame layout we can't dump r0 - r3, but these
* are less frequently saved.
*
* Stack frame layout:
* <larger addresses>
* saved lr
* frame=> saved fp
* optionally saved caller registers (r4 - r10)
* optionally saved arguments (r0 - r3)
* <top of stack frame>
* <smaller addresses>
*
* Functions start with the following code sequence:
* corrected pc => stmfd sp!, {..., fp, lr}
* add fp, sp, #x
* stmfd sp!, {r0 - r3} (optional)
*
*
*
*
*
*
* The diagram below shows an example stack setup for dump_stack.
*
* The frame for c_backtrace has pointers to the code of dump_stack. This is
* why the frame of c_backtrace is used to for the pc calculation of
* dump_stack. This is why we must move back a frame to print dump_stack.
*
* The stored locals for dump_stack are in dump_stack's frame. This means that
* to fully print dump_stack's frame we need both the frame for dump_stack (for
* locals) and the frame that was called by dump_stack (for pc).
*
* To print locals we must know where the function start is. If we read the
* function prologue opcodes we can determine which variables are stored in the
* stack frame.
*
* To find the function start of dump_stack we can look at the stored LR of
* show_stack. It points at the instruction directly after the bl dump_stack.
* We can then read the offset from the bl opcode to determine where the branch
* takes us. The address calculated must be the start of dump_stack.
