9// This file defines the VE Vector Predicated SDNodes (VVP SDNodes).  VVP
10// SDNodes are an intermediate isel layer between the vector SDNodes emitted by
11// LLVM and the actual VE vector instructions. For example:
12//
13//  ADD(x,y)   -->   VVP_ADD(x,y,mask,evl)   -->   VADDSWSXrvml(x,y,mask,evl)
14//     ^                      ^                            ^
15//  The standard     The VVP layer SDNode.        The VE vector instruction.
16//  SDNode.
17//
18// TODO explain how VVP nodes relate to VP SDNodes once VP ISel is uptream.
