(vect_analyze_stmt): If we are analyzing a pure SLP stmt and got called from loop analysis bail out. Always pass the SLP node to the vectorizable_* functions. * tree-vect-loop.c (vect_analyze_loop_operations): Remove the premature SLP check here. * tree-vect-slp.c (vect_detect_hybrid_slp_stmts): Dump hybrid detected SLP stmts. (vect_detect_hybrid_slp_1): Likewise.
