--- Comment #1 from Isabella <izaberina at gmail dot com> ---
int a;

static void __attribute__((noinline)) f1() { a = 7; }
void g1(void) { f1(); }


static void __attribute__((noinline)) f2(void) { a = 7; }
void g2(void) { f2(); }


gets compiled to


f1:
  movl $7, a(%rip)
  ret
f2:
  movl $7, a(%rip)
  ret
g1:
  xorl %eax, %eax
  jmp f1
g2:
  jmp f2
