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); } -- Invent and fit; have fits and reinvent!
