tree-optimization/105132 - add missing checking in vectorizable_operation
The following adds missing verification that the input vectors have the same number of elements for vectorizable_operation. 2022-04-04 Richard Biener <rguenther@suse.de> PR tree-optimization/105132 * tree-vect-stmts.cc (vectorizable_operation): Check that the input vectors have the same number of elements. * gcc.dg/torture/pr105132.c: New testcase.
