Detailed Description

   A computation tree of an SLP instance.  Each node corresponds to a group of
   stmts to be packed in a SIMD stmt.

Field Documentation

vec<slp_tree> _slp_tree::children

     Nodes that contain def-stmts of this node statements operands.  

vec<unsigned> _slp_tree::load_permutation

     Load permutation relative to the stores, NULL if there is no
     permutation.  

Referenced by vect_mark_slp_stmts_relevant(), and vect_slp_rearrange_stmts().

vec<gimple> _slp_tree::stmts

     A group of scalar stmts to be vectorized together.  

vec<gimple> _slp_tree::vec_stmts

     Vectorized stmt/s.  

unsigned int _slp_tree::vec_stmts_size

     Number of vector stmts that are created to replace the group of scalar
     stmts. It is calculated during the transformation phase as the number of
     scalar elements in one scalar iteration (GROUP_SIZE) multiplied by VF
     divided by vector size.
