How to run converted .asm code from .c using 'gcc' in Emu8086 - c

Question

I am new here and I converted code from C language to asm. However, it doesn't look like normal code in asm language. So my question is how can I convert a code from C(or C++) language to Assembly language, that the converted asm code could be run on Emu8086.
Here is a simple c code:
#include<stdio.h>
void Hello(){
printf("Hello world");
}
int main (){
Hello();
return 0;
}
Then I converted it with gcc -S test.c and here is the answer:
.file "test1.c"
.section .rodata
.LC0:
.string "Hello world"
.text
.globl Hello
.type Hello, #function
Hello:
.LFB0:
.cfi_startproc
pushq %rbp
.cfi_def_cfa_offset 16
.cfi_offset 6, -16
movq %rsp, %rbp
.cfi_def_cfa_register 6
leaq .LC0(%rip), %rdi
movl $0, %eax
call printf#PLT
nop
popq %rbp
.cfi_def_cfa 7, 8
ret
.cfi_endproc
.LFE0:
.size Hello, .-Hello
.globl main
.type main, #function
main:
.LFB1:
.cfi_startproc
pushq %rbp
.cfi_def_cfa_offset 16
.cfi_offset 6, -16
movq %rsp, %rbp
.cfi_def_cfa_register 6
movl $0, %eax
call Hello
movl $0, %eax
popq %rbp
.cfi_def_cfa 7, 8
ret
.cfi_endproc
.LFE1:
.size main, .-main
.ident "GCC: (Debian 6.3.0-18+deb9u1) 6.3.0 20170516"
.section .note.GNU-stack,"",#progbits

Emu8086 does what it says on the tin: it emulates an Intel 8086 processor. The assembly that GCC has produced is for your host machine (since you haven't told it to do otherwise), which evidently uses an x86-64 instructions set. The 8086 can't understand most of these instructions. You need to cross-compile it to an x86 16-bit real-mode executable. The -m16 option on GCC will generate 16-bit code, but it apparently still uses 32-bit registers (EAX, etc.). So you will have to find a compiler that targets the basic 8086 instruction set.
