...fore, values with aggregate types need to be break apart to be represented by a SDValue. * Implications * - Instructions that may accept aggregate type, e.g., load, store, and select, must be split to handle the different component that compose a Value. (Look for the use of ComputeValueVTs in the SelecionDAGBuilder and the related loops this implies). - Use of aggregate type generates a bunch of MERGE_VALUE nodes, which sole purpose is to glue all the components that make the aggregate type together. Therefore, in practice, values with aggregate types are mapped to several SDValue hidden in MERGE_VALUE nod...
