--- Comment #3 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
I don't even understand what this code is trying to warn about:
if (TREE_CODE (arg2_type) == ENUMERAL_TYPE
&& TREE_CODE (arg3_type) == ENUMERAL_TYPE)
{
if (TREE_CODE (orig_arg2) == CONST_DECL
&& TREE_CODE (orig_arg3) == CONST_DECL
&& DECL_CONTEXT (orig_arg2) == DECL_CONTEXT (orig_arg3))
/* Two enumerators from the same enumeration can have different
types when the enumeration is still being defined. */;
else if (complain & tf_warning)
warning_at (loc, OPT_Wenum_compare, "enumeral mismatch in "
"conditional expression: %qT vs %qT",
arg2_type, arg3_type);
}
What is the DECL_CONTEXT check doing there?
