Require understanding of increment in assembly during Undefined behaviors in C program

I came across Undefined behavior in this C code below:

#include <stdio.h>

int main()
{
    int x=0,y=5;
    printf("x=%d,x_1=%d,sum=%d",x++,x,y+x);
    return 0;
}

Just out of curiosity, i tried checking assembly of the same to see if i can understand how loading and execution has occurred but couldn't understand it much. Volunteers, could you please help me understand order in which the implementation has actually occured?

    .file   "example.c"
    .text
    .section    .rodata
.LC0:
    .string "x=%d,x_2=%d,y=%d\n"
    .text
    .globl  main
    .type   main, @function
main:

    .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    $0, -8(%rbp)
    movl    $5, -4(%rbp)
    movl    -4(%rbp), %edx
    movl    -8(%rbp), %eax
    leal    (%rdx,%rax), %ecx
    movl    -8(%rbp), %eax
    leal    1(%rax), %edx
    movl    %edx, -8(%rbp)
    movl    -8(%rbp), %edx
    movl    %eax, %esi
