天然气与NASM：该汇编产生最佳code？ [英] gas vs. nasm: which assembler produces the best code?

问题描述

这两个工具翻译汇编指令直接放入机器code，但有可能确定哪一个生产最快和最干净的code？

Both tools translate assembly instructions directly into machine code, but is it possible to determine which one produces the fastest and cleanest code?

推荐答案

当你在编译器的时候，您是precisely说明指令生成所以它不依赖于汇编。这取决于你。有你写的助记符和实际指令机器code之间的一个一一对应。

When you're writing in assembler, you are precisely describing the instructions to generate so it doesn't depend on the assembler. It depends on you. There's a one-to-one correspondence between the mnemonics you write and actual instructions in machine code.
