    For the following program, compiling with `clang -g -O1 test.cpp -o test.elf`.
```
inline int foo(int x) {
  volatile int local = x + 1;
  return local;
}

int main(int argc, char** argv) {
  volatile int local = 0;
  local += foo(argc);
  return local;
}
```
Using `s` at the end, we can see the value of `x` is 1.
`lldb -O "target create test.elf" -o "b test.cpp:7" -o "r" -o "s" -o "s"`
But if using `si` at the end, it shows value of `x` is unavailable. 
`lldb -O "target create test.elf" -o "b test.cpp:7" -o "r" -o "s" -o "si"`
