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);
}
