bug#10439: 24.0.92; semantic-complete-jump prefers declaration over defi


From: Tom Tromey
Subject: bug#10439: 24.0.92; semantic-complete-jump prefers declaration over definition
Date: Thu, 05 Jan 2012 10:48:48 -0700

Consider this .c file:

static int collect_stuff (void);

int main ()
{
  collect_stuff();
}

static int collect_stuff (voi)
{
  return 23;
}


First, M-x semantic-mode.
Put point inside main.
Then 'C-c , J' (semantic-complete-jump) to "collect_stuff".

Semantic will jump to the declaration on line 1.
I think it would be better if it worked like:

* If point is inside a declaration or definition, put that entity at the
  end of the list, and jump to the first item in the list.
  In this example, if point was on line 1, it would jump to the definition;
  and if point is in the definition, it would jump to line 1.
* Otherwise, prefer a definition over any declaration.
