I cant convert a c code to assembly code properly
the code is
#include <stdio.h> /* Standard Library of Input and Output */
#include <complex.h> /* Standard Library of Complex Numbers */
double complex power(double complex value, int power){
double complex result=1;
for (int i=0;i<power;i++){
result = result * value;
}
return result;
}
double complex function(double order,double complex * array,double complex value) // a function that calculates f(x)
{
double complex result=0;
for (int i = order ; i >= 0 ; i--){
result = result + array[i]*(power(value,i));
}
//printf("the value of f(x) is: = %.10f %+.10fi\n",creal(result), cimag(result));
return result;
}
double complex derivefunction(double order,double complex * array,double complex value,double complex * darray){
for (int i = order-1 ; i >= 0 ; i--){
darray[i] = array[i+1]*(i+1);
}
return function(order-1,darray,value);
}
double abs(double m){//absolute
if (m<0)
return -m;
return m;
}
int main(void) {
double tol,order;
double arrayr[100];//assuming the maximum order is 0
double arrayi[100];
double complex array[100];
printf("Enter the tolarence:\n");
scanf("%lf", &tol);
printf("the toleracnce is: %.10f\n",tol);
printf("Enter the order\n");
scanf("%lf", &order);
printf("the order is: %lf\n",order);
for (int i = order ; i >= 0 ; i--){
printf("Enter the %d coeficience\n",i);
scanf("%lf", &(arrayr[i]));//taking the real number
scanf("%lf", &(arrayi[i]));// taking the imaginary number
array[i] = arrayr[i] + arrayi[i] * I;//summing the complex number
printf("The %d coeficience is = %.2f %+.2fi\n",i ,creal(array[i]), cimag(array[i]));
}
double initialr, initiali;
double complex initial;
printf("Enter the initial value of z(the guss) \n");
scanf("%lf", &initialr);//taking the real number
scanf("%lf", &initiali);// taking the imaginary number
initial = initialr + initiali*I;
printf("The initial is = %.2f %+.2fi\n", creal(initial), cimag(initial));
double complex result1 = function(order,array,initial);
if (order > 0) {
double complex darray[sizeof(array)];
double complex result2 = derivefunction(order,array,initial,darray);
//now the newton-rashford method
double complex m = result1/result2;//the initial
while (abs((double)(m)) >= tol)//if it is in the range
{
m = function(order,array,initial) / derivefunction(order,array,initial,darray);//f(x)/f'(x)
initial = initial - m;
//printf("The initial is = %.10f %+.10fi\n", creal(initial), cimag(initial));
}
printf("The root is = %.10f %+.10fi\n", creal(initial), cimag(initial));
}
return 0;
}
I used the command gcc -S -O main.c to create an assembly file called main.s but when I try to compile the assembly file I get many errors
nasm -g -f elf64 -w+all -o main.o main.s
main.s:1: error: attempt to define a local label before any non-local labels
main.s:1: error: parser: instruction expected
main.s:2: error: attempt to define a local label before any non-local labels
and so on.. I think it relates to the fact that I use complex number but I am not sure how to fix this.
