[lwip-devel] [patch #8742] lwIP fails to build with NO_SYS=1 in single stack mode

[Sylvain Rochet]

Follow-up Comment #4, patch #8742 (project lwip):

OK, you made me doubt ;-), so I checked, at least with gcc:


#include <stdio.h>

static int test_a(void);
static int test_b(void);

static int test_a(void) {
        test_b();
}

static int test_b(void) {
        printf("Hello World !\n");
        printf("Hello World !\n");
        printf("Hello World !\n");
}

static int caller(int (*f)(void)) {
        return f();
}

int main() {
        test_b();
        caller(test_a);
}

$ gcc -O2 -o test test.c && nm -S ./test | grep test_
0000000000400520 0000000000000026 t test_b



test_a() was aliased into test_b()
