How to suppress the generation of float point instructions?

[Ender.Dai]

Hi, all,

Following demo code will generate float point instruction "lfd" by
compile it with command "powerpc-linux-uclibc-gcc demo.c -S". Since
the actual working code is a part of linux kernel,  I just wanna
suppress the generation of float point instructions. Is there any
way(some gcc flags for example) to finish this job? Thanks in advance.

#include <stdio.h>

#define SIZE 2

typedef struct {
  int arr[SIZE];
} arr_s;

int printArr(arr_s var)
{
  int i;
  for(i=0; i<SIZE; i++) {
    printf("var.arr[%d] = %d\n", i, var.arr[i]);
  }
  return 0;
}

int main()
{
  arr_s parm = { 1, 2 };
  return printArr(parm);
}
