• Loader: This is the part of the operating system responsible for loading the program into memory.
• Pre-init Array (preinitarray1.n): Before the main initialization, functions defined in a pre-initialization array are executed. This is where any pre-initialization setup can occur.
• Start (_start): This is the entry point of the program provided by the runtime environment. It sets up the environment for the program execution.
• libc_start_main: This function is part of the C library (glibc). It performs necessary initializations for the C library and then calls the main function of the program.
• libc_csu_init: This is part of the initialization sequence, setting up the environment before calling init.
• Init (_init): This is typically where static constructors and other initialization functions are run.
• Initialization Array (initarray1.n): Functions in this array are called during the initialization phase, after _init but before main.
• Main (main): The main function of the program, where the actual program logic starts.
• Exit (exit): When the program is about to terminate, it goes through an exit sequence.
• At Exit (atexiti.n): Functions registered to run at exit are executed here.
• Fini Array (finiarray1.n): Functions in this array are called during the program termination, after main returns but before the final cleanup.
• Destructor (destructor1.n): Destructors for static objects are called here.
• Global Constructors (do_global_ctors_aux, constructors1.n): These are functions that construct global objects, part of the C++ runtime.
• Frame Dummy: This might refer to frame unwinding setup or dummy frame setup for debugging or exception handling.
• Gmon Start (__gmon_start__): This is often related to profiling or gprof, a performance analysis tool.
