Different stages of execution of a c program

In this stage, the preprocessed code is translated to assembly instructions specific to the target processor architecture. These form an intermediate human readable language. The existence of this step allows for C code to contain inline assembly instructions and for different assemblers to be used. Some compilers also supports the use of an integrated assembler, in which the compilation stage generates machine code directly, avoiding the overhead of generating the intermediate assembly instructions and invoking the assembler.

To save the result of the compilation stage, pass the -S option to cc :. On macOS During this stage, an assembler is used to translate the assembly instructions to object code. The output consists of actual instructions to be run by the target processor. To save the result of the assembly stage, pass the -c option to cc :.

So, here it will create the first. The process is continued by the Linker which finally gives a. Linker : First of all, let us know that library functions are not a part of any C program but of the C software. The definitions of these functions are stored in their respective library which the compiler should be able to link. This is what the Linker does. So, when we write include, it includes stdio. The linker links the object files to the library functions and the program becomes a.

Here, first. Loader : Whenever we give the command to execute a particular program, the loader comes into work. The loader will load the.
