// pinvoke_ppcf.cs - Test cases for passing structures to and and returning
//                   structures from functions.  This particular test is for
//                   structures consisting wholy of 4 byte fields.
//
//                   The Power ABI version 2 allows for special parameter
//                   passing and returning optimizations for certain
//                   structures of homogenous composition (like all ints).
//                   This set of tests checks all the possible combinations
//                   that use the special parm/return rules and one beyond.
