-/* In VAR_DECL, PARM_DECL and RESULT_DECL nodes, nonzero means address
- of this is needed. So it cannot be in a register.
+/* In VAR_DECL nodes, nonzero means address of this is needed.
+ So it cannot be in a register.
In a FUNCTION_DECL, nonzero means its address is needed.
So it must be compiled even if it is an inline function.
+ In a FIELD_DECL node, it means that the programmer is permitted to
+ construct the address of this field. This is used for aliasing
+ purposes: see record_component_aliases.
In CONSTRUCTOR nodes, it means object constructed must be in memory.
In LABEL_DECL nodes, it means a goto for this label has been seen
from a place outside all binding contours that restore stack levels.
