Compare and analyze the structure of the two assembly codes generated by gcc??? please can someone explain it, thanks

.file "lab5_prob3_1.c"

.section .rodata

.LC0:

.string "Hello, world"

.text

.globl main

.type main, @function

main:

.LFB0:

.cfi_startproc

pushq %rbp

.cfi_def_cfa_offset 16

.cfi_offset 6, -16

movq %rsp, %rbp

.cfi_def_cfa_register 6

subq $16, %rsp

movl %edi, -4(%rbp)

movq %rsi, -16(%rbp)

movl $.LC0, %edi

call puts

movl $0, %eax

leave

.cfi_def_cfa 7, 8
