DECL_VALUE_EXPR should not return null if DECL_HAS_VALUE_EXPR_P
returns true.

DECL_VALUE_EXPR should not return null if DECL_HAS_VALUE_EXPR_P
returns true.

------- Comment #2 from pinskia at gcc dot gnu dot org 2008-11-13 19:21 -------
Can you explain why you think DECL_VALUE_EXPR will return a NULL if
DECL_HAS_VALUE_EXPR_P is set? I don't see anywhere in the code which sets
DECL_HAS_VALUE_EXPR_P and does not insert something into the hash table.

Hash table entries should be reordered when writing a PCH.
