与GCC 内联汇编语法一样,Rust 希望即使需要手写汇编,程序员也能将一部分工作交给编译器来高效完成,这部分工作就是寄存器分配,毕竟只有编译器了解内联汇编前后的上下文,知道该怎么分配寄存器最合适。 asm宏的in,out,inout,lateout,inlateout参数就是为了让编译器帮助分配寄存器的。 in表示将变量的值传给寄存器,编译器...

在 Rust 中，内联汇编使用类似于 GCC 的语法，但融入了 Rust 的特色，如寄存器自动分配。`in`、`out`、`lateout` 等参数允许程序员利用编译器的优化策略，高效地进行参数传递。局部内联汇编通常在函数体中使用，而全局内联汇编则提供更大的控制，但不包含自动寄存器分配功能，需要程序员自行管理。程序名...

由于低水平的操作和性能,人们希望直接控制 CPU。Rust 通过 asm!宏来支持使用内联汇编。语法大致匹配 GCC & Clang :asm!(assembly template : output operands : input operands : clobbers : options );任何asm 的使用是特征封闭的(需要库的 #![feature(asm)] 允许),当然需要一个 unsafe 块。
