Detailed Description

This class sets up an RVSDG representing the following code:

#include <stdarg.h>
#include <stdio.h>
#include <stdint.h>
 
static int
fst(int n, ...)
{
  va_list arguments;
  va_start(arguments, n);
  int tmp = va_arg(arguments, int);
  va_end(arguments);
 
  return tmp;
}
 
int
g()
{
  return fst(3, 0, 1, 2);
}

It uses a single memory state to sequentialize the respective memory operations within each function. The code produced by the compiler for variadic functions is architecture specific. This function sets up the code that was produced for x64.
