如果要指定變數存在某個section裡,可以用下列的方式宣告。
(下面的STACK為指定的section name,您可以改為任何section name)
char stack[10000] __attribute__ ((section ("STACK"))) = { 0 };

也可以指定function放在某個section裡。
語法


#include <stdio.h>
#include <stdlib.h>
int __attribute__ ((section ("FUNCTIONA"))) mul2(int);

int main(void) {
printf("2*30=%d\n", mul2(30));
return EXIT_SUCCESS;
}

int mul2(int num){
return 2*num;
}
