Question

The portion of the generated assembly code implementing the C function int (int x, int y, int z) is as follows: Based on this assembly code, fill in the missing portions of the C code. Verify your answer using gcc compiler. Note: x in %edi, y in %esi, z in %edx.

Please answer in C language.

func (int, int, int):
pushq
%rbp
movq
%rsp, %rbp
movl
%edi, -20(%rbp)
movl
%esi, -24(%rbp)
movl
%edx, -28(%rbp)
movl
-20 ( %rbp), %edx
movl
-24 ( %rbp), %eax
addl
$edx, %eaх
$11, %eax
Fill in this c code based on the assembly code:
addl
movl
Веax, -4 (8rbp)
movl
-4 ( %rbp), %eax
Int func(int x, int y, int z){
subl
$4, %eax
movl
веах, -8(8rbp)
}
int main(){
}
movl
-8 ( %rbp), %eax
popq
%rbp
ret
main:
pushq
%rbp
movq
%rsp, %rbp
subq
$16, %rsp
movl
$3, %edx
movl
$2, %esi
movl
$1, %edi
call
func(int, int, int)
movl
%eax, -4(%rbp)
