Embodiment Construction
[0026] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] Such as figure 1 As shown, it is a structural schematic diagram of a part of the structure of a PPC stack frame. PPC, or PowerPC, is a computer processor architecture specification. The stack frame refers to a section of stack space opened up in the memory stack when the function is running. The PPC stack frame structure has different fields, including: function parameter register save area (FPR save area), general register save area (GPR save area), condition register save field (CR save word, Conditon Register save word), local variables Area (local variables area), function parameters area (function parameters area), padding to adjust size to multiple of 8 bytes (padding to adjust size to multiple of 8 bytes), link register save field (LR Save Word, Link Register Save Word), the back chain field (Back Chain Word), each field has its...
