◆ AnalyzeArguments()

template<typename ArgT >
static void AnalyzeArguments ( CCState State,
SmallVectorImpl< CCValAssign > &  ArgLocs,
const SmallVectorImpl< ArgT > &  Args 
)
static

Analyze incoming and outgoing function arguments.

We need custom C++ code to handle special constraints in the ABI like reversing the order of the pieces of splitted arguments. In addition, all pieces of a certain argument have to be passed either using registers or the stack but never mixing both.
