| 5130 | Generate at least SIZE bytes of assembler data, padding at the end |
| 5131 | with zeros if necessary. SIZE must always be specified. The returned |
| 5132 | value is the actual number of bytes of assembler data generated, which |
| 5133 | may be bigger than SIZE if the object contains a variable length field. |
| 5134 | |
| 5135 | SIZE is important for structure constructors, |
| 5136 | since trailing members may have been omitted from the constructor. |
| 5137 | It is also important for initialization of arrays from string constants |
| 5138 | since the full length of the string constant might not be wanted. |
| 5139 | It is also needed for initialization of unions, where the initializer's |
| 5140 | type is just one member, and that may not be as long as the union. |
| 5141 | |
| 5142 | There a case in which we would fail to output exactly SIZE bytes: |
| 5143 | for a structure constructor that wants to produce more than SIZE bytes. |
