Check whether the specified array bound can be evaluated using the relevant language rules.

If so, returns the possibly-converted expression and sets SizeVal to the size. If not, but the expression might be a VLA bound, returns ExprResult(). Otherwise, produces a diagnostic and returns ExprError().

Complains about missing nullability if the file containing pointerLoc has other uses of nullability (either the keywords or the assume_nonnull pragma).

static

Applies a nullability type specifier to the given type, if possible.

Parameters

state	The type processing state.
type	The type to which the nullability specifier will be added. On success, this type will be updated appropriately.
attr	The attribute as written on the type.
allowOnArrayType	Whether to accept nullability specifiers on an array type (e.g., because it will decay to a pointer).

Returns: true if a problem has been diagnosed, false on success.

static

Returns true if any of the declarator chunks before endIndex include a level of indirection: array, pointer, reference, or pointer-to-member.

Because declarator chunks are stored in outer-to-inner order, testing every chunk before endIndex is testing all chunks that embed the current chunk as part of their type.

It is legal to pass the result of Declarator::getNumTypeObjects() as the end index, in which case all chunks are tested.
