• Code Segments

Below is a list of some of the code segments that GCC can produce with descriptions of their purpose.

Below is an example taken from the Xilinx application note xapp642

#include <stdio.h>

int array_data[10] = {0,1,2,3,4,5,6,7,8,9};

const int array_const[10] = {9,8,7,6,5,4,3,2,1,0};

int main(void)

{

   int i;

   i = i + 10;

   printf("%d\n", array_data[0]);

   array_data[0] = array_const[0];

   printf("%d\n",array_data[0]);

   return 0;

}
