ESP = ? stack pointer

什么 E 站在这里?

更新

64位的RSP?

什么 R这里的意思?

最佳答案

E代表 Extended

With the advent of the 32-bit 80386 processor, the 16-bit general-purpose registers, base registers, index registers, instruction pointer, and FLAGS register, but not the segment registers, were expanded to 32 bits. This is represented by prefixing an "E" (for Extended) to the register names in x86 assembly language.
