<h5>Arguments:</h5>
|
||||
|
||||
The first argument is a pointer to a <tt>va_list</tt> element to initialize.
|
||||
The second argument is required to be the last LLVM argument before the
|
||||
ellipsis. In the future, this restriction may be relaxed (to allow it to be
|
||||
other arguments).<p>
|
||||
The argument is a pointer to a <tt>va_list</tt> element to initialize.<p>
|
||||
|
||||
<h5>Semantics:</h5>
|
||||
|
||||
The '<tt>llvm.va_start</tt>' intrinsic works just like the <tt>va_start</tt>
|
||||
macro available in C. In a target-dependent way, it initializes the
|
||||
<tt>va_list</tt> element the first argument points to, so that the next call to
|
||||
<tt>va_arg</tt> will produce the first variable argument passed to the
|
||||
function.<p>
|
||||
<tt>va_list</tt> element the argument points to, so that the next call to
|
||||
<tt>va_arg</tt> will produce the first variable argument passed to the function.
|
||||
Unlike the C <tt>va_start</tt> macro, this intrinsic does not need to know the
|
||||
last argument of the function, the compiler can figure that out.<p>
