  | commit gcc-15-3514-gea9d4bf45ef9
  | Author: Richard Biener <rguenther@suse.de>

  |     Fix SLP double-reduction support
  |     
  |     When doing SLP discovery I forgot to handle double reductions even
  |     though they are already queued in LOOP_VINFO_REDUCTIONS.
  |     
  |             * tree-vect-slp.cc (vect_analyze_slp): Also handle discovery
  |             for double reductions.
