/**
|
|
* \brief Rewrite the Call Nodes marked type as CINN, pack their arguments into
|
|
* `void*, int` so that they can trigger a `LoweredFunc`.
|
|
*
|
|
* For example, input the IR
|
|
* \code
|
|
* Call(some_lowered_func, a:cinn_buffer_t*, b:cinn_buffer_t*, c:cinn_buffer_t*)
|
|
* \endcode
|
|
*
|
|
* This pass will rewrite it to
|
|
* \code
|
|
* cinn_pod_value_t a_(a);
|
|
* cinn_pod_value_t b_(b);
|
|
* cinn_pod_value_t c_(c);
|
|
*
|
|
* cinn_args_construct(packed_args, a_, b_, c_);
|
|
* Call(some_lowered_func, packed_args, 3); // 3 is the number of arguments
|
|
* \endcode
