Detailed Description

Represents a C99 designated initializer expression.

A designated initializer expression (C99 6.7.8) contains one or more designators (which can be field designators, array designators, or GNU array-range designators) followed by an expression that initializes the field or element(s) that the designators refer to. For example, given:

struct point {
  double x;
  double y;
};
struct point ptarray[10] = { [2].y = 1.0, [2].x = 2.0, [0].x = 1.0 };

The InitListExpr contains three DesignatedInitExprs, the first of which covers [2].y=1.0. This DesignatedInitExpr will have two designators, one array designator for [2] followed by one field designator for .y. The initialization expression will be 1.0.
