Hi Keith,

with attached file on Fedora 25 x86_64 'gcc -g' (not any -O):

I think g is inlined into h which is inlined into main.  Personally I think it
would be enough to say "in g" as the rest is a toolchain implementation detail.
But if it tries to describe the code layout then it should match the reality.

The MI attributes would also need to be adjusted for multi-level inlines.

int e;

static __attribute__ ((__noinline__)) void
f (int a)
{
  e = a;
}

static __attribute__ ((__always_inline__)) void
g (int a)
{
  f (a);

  e = a;
}

static __attribute__ ((__always_inline__)) void
h (int a)
{
  g (a);

  e = a;
}

int
main (void)
{
  h (1);

  return 0;
}
