re PR tree-optimization/92173 (ICE in optab_for_tree_code, at optabs-tree.c:81)
2019-10-22 Richard Biener <rguenther@suse.de>
PR tree-optimization/92173
* tree-vect-loop.c (vectorizable_reduction): If
vect_transform_reduction cannot handle code-generation try without
the single-def-use-cycle optimization. Pass optab_vector to
optab_for_tree_code to get vector shifts as that's what we'd
generate.
* gcc.dg/torture/pr92173.c: New testcase.
