Final answer:
In x86 assembly, rsp serves as the stack pointer, managing the top of the stack in memory, while rbp is utilized as the base pointer, offering a reference point within a subroutine's stack frame.
Step-by-step explanation:
In x86 assembly language, rsp and rbp are special-purpose registers with distinct roles. The rsp register is used as the stack pointer. It holds the address of the top of the stack and is adjusted automatically during push and pop operations. Meanwhile, rbp is used as the base pointer, which is typically used by high-level languages to create a stable point of reference for the stack frame of a subroutine. This allows for easier access to parameters and local variables of the function.
