[Bug c++/31246] Strange -Wunreachable-code warning with _GLIBCXX_DEBUG

[pinskia at gcc dot gnu dot org]

------- Comment #14 from pinskia at gcc dot gnu dot org  2007-03-19 23:18 -------
But the user can see the code, it is what is produced by what the C++ standard
says is produced, now you could say the user has no control over fixing it, it
is also true with the template case.  Both cases are hard to fix without much
thought.  There is also something like:

static inline int f(int a)
{
  if (a)
   return g();
  return 0;
}


int h(void)
{
  return f(0);
}

With -Wunreachable-code -O1, we warn that we cannot reach the line containing
return g();  Now should we, it is the same case, how can an user fix that code
if the static inline function comes in from a header, they cannot. 
-Wunreachable-code warning is useless except if you want to see if you do
coverage.
