If things between (2) and (3) are completely unnecessary after the second stage is complete, they will be moved to (1. Next we will talk about elf loader.

What is the worst-case scenario when writing a program without a debugger? When compiling, kneel and pray, do not make mistakes? Call the demon with a blood sacrifice to help you run the program? Or do you want to add a printf ("test") statement between each line of code to locate the error point? As you know, it is inconvenient to write a

and print it out! So we have the following story... Compiler built-in macros: First, we will introduce several built-in macro definitions of the compiler. These macro definitions can not only help us write cross-platform source code, but also help us output useful debugging information flexibly. The ansi c standard has several predefined macros (which are also commonly used ): _ Line __: Insert the current source code
