[Bug tree-optimization/38844] [4.3/4.4 Regression] deadlock with __attribute__((always_inline)) at -O1 and above

[jakub at gcc dot gnu dot org]

------- Comment #10 from jakub at gcc dot gnu dot org  2009-01-28 21:47 -------
Further testcases:

inline __attribute__((always_inline))
void A (void)
{
  A ();
  A ();
  A ();
}

int
main ()
{
  A ();
  return 0;
}

and:

inline void A (void);
inline void B (void);

inline __attribute__ ((always_inline))
void C (void)
{
  B ();
}

inline __attribute__ ((always_inline))
void B (void)
{
  A ();
}

inline __attribute__ ((always_inline))
void A (void)
{
  A ();
  B ();
  C ();
}

int
main ()
{
  A ();
  return 0;
}

Perhaps just changing node->aux for all nodes for which recursive
cgraph_decide_inlining_incrementally will be called would work.
