function return value The return value type must be the same as the return type of the function For the main function, the return value must be of type int. In most systems, the return value of the main function is a status indicator. A return value of 0 indicates that the main function completed successfully, and a non-zero return indicates an error occurred.

Of course, this is a historical reason, because Linux since its inception is the 32-bit, is a multi-user multitasking operating system, so the GCC and GNU as a migration to Linux is used to write 32-bit protection mode of code.

Part 1 arm assembly syntax in Linux Although it is convenient to use C or C ++ to write programs in Linux, the assembler source program is used for the most basic initialization of the system, such as initializing the stack pointer, setting the page table, and operating the arm coprocessor. After initialization, you can jump to C code execution. Note that the GNU assembler follows att's Assembly syntax and can download the relevant specifications from
