VerifiedOn x86-64 Linux, the C ABI follows the System V AMD64 ABI specification: the first 6 integer/pointer arguments are passed via the RDI, RSI, RDX, RCX, R8, and R9 registers, floating-point arguments are passed via XMM0–XMM7, and the return value is placed in RAX.78% similarUnverifiedx86-64架构使用RSP寄存器作为栈指针寄存器来管理栈75% similarUnverified栈由 CPU 硬件寄存器（如 x86 架构的 RSP/RBP）直接管理，随函数调用自动压栈、随函数返回自动弹栈71% similarUnverifiedx86 real mode is the native operating mode of the 8086/8088 processor; almost all DOS programs run in this mode, directly reading and writing hardware I/O ports via IN/OUT instructions.70% similarUnverifiedINT3（操作码0xCC）是x86架构中为调试器设计的单字节中断指令，触发后CPU产生#BP异常（异常向量3）69% similar
