re PR tree-optimization/37021 (Fortran Complex reduction / multiplication not vectorized)
2013-03-28 Richard Biener <rguenther@suse.de>
PR tree-optimization/37021
* tree-vect-slp.c (vect_build_slp_tree): When not unrolling
do not restrict gaps between groups.
* tree-vect-stmts.c (vectorizable_load): Properly account for
a gap between groups.
* gcc.dg/vect/fast-math-slp-38.c: New testcase.
* gcc.dg/vect/O3-pr36098.c: Un-XFAIL.
