I am trying to fold array[7] into 2. It turns out that if T is an ARRAY_REF,
TREE_READONLY (TREE_OPERAND (T, 0))
is 0. Why?
I don't know anything about fold but in general a c++ array in the frontend is cv-qualified, not its elements.
Another question. How is a RANGE_EXPR used in a C++'s array constructor? The CONSTRUCTOR section of tree.def says
I created an array with more than one thousand elements. I still did not see a RANGE_EXPR in the array's CONSTRUCTOR. How do I get a RANGE_EXPR in a CONSTRUCTOR?
I have been processing large source codes including STL, boost and custom code including function bodies and I have never seen a RANGE_EXPR. I suppose it's only used at later stages or only in other language's frontends.
