// 4. Passing the parameters.
//
// The compiler knows how to call functions, so having sorted out the argument list,
// we just pass it to a function of the correct form - and let the compiler align stacks,
// load registers, place parameters where they should be.
//
// This is particularly important as GCC has control over the stack frame, and it can
// improperly frame it - for instance utilising red zones to save args, rather than pushing them.
// On PowerPC it must create the parameter passing area, too.
//
// The most brute force way, is to code a function call for every possible number of parameters
//
// switch( paramc ) {
// case 1: ( (void(AUTO_RPC_CALLSPEC*)(NaturalWord)) myfunc)( callParam[0] ); break;
// case 2: ( (void(AUTO_RPC_CALLSPEC*)(NaturalWord,NaturalWord)) myfunc)( callParam[0], callParam[1] ); break;
// ...
// case 64: ( (void(AUTO_RPC_CALLSPEC*)(NaturalWord,NaturalWord)) myfunc)( callParam[0], callParam[1], ... , callParam[63] ); break;
// }
//
// This is the only way to code WIN32 stdcall, for example, as the args must match exactly;
// and so the only way to call from C if you need to call WINAPI routines.
//
// 2) Fortunately most calling conventions allowing excessive args. So this means we could
// write something like below:
//
// ( (void(*)(...)) myfunc )( args[0],...,args[63] );
//
// And although this should work, its a huge performance penalty copying between memory
// locations for so many args.
//
// So we compromise - and do a stepped sequence. Noticing that the WIN64 ABI alwys requires
// space for three args anyway.
//
// And on SysV x64 systems, the first 6 args are passed in reg; so again, these are only
// copies into register, not memory copies. And finally that if we load word[n], word[n+1]
// is loaded into the cache - thus the overhead for loading is not as big as it might be.
//
// For most realistic cases, a dozen args would be excessive. Obviously, if you have
// a tested assembler equivalent, its probably better to use that.
