- 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.
