I.e. you find code like

         if AController.CurrentProcess.Mode=dm32 then
           Reg := RegList.FindRegisterByDwarfIndex(8)
         else
           Reg := RegList.FindRegisterByDwarfIndex(16);

(evaluating the stack)

RegList should have methods:
.GetStackBase
.GetInstructionPointer

And reading the stack, may have to be moved to OS/CPU specific classes, 
if stack-frame layout may differ.
