   1 // pinvoke_ppcd.cs - Test cases for passing structures to and and returning
   2 //                   structures from functions.  This particular test is for
   3 //                   structures consisting wholy of 8 byte fields.
   4 //
   5 //                   The Power ABI version 2 allows for special parameter
   6 //                   passing and returning optimizations for certain
   7 //                   structures of homogenous composition (like all ints).
   8 //                   This set of tests checks all the possible combinations
   9 //                   that use the special parm/return rules and one beyond.
