tree-optimization/102142 - fix typo in loop BB reduc cost adjustment
This fixes a typo in the condition guarding the cleanup of the visited flag of costed scalar stmts. 2021-08-31 Richard Biener <rguenther@suse.de> PR tree-optimization/102142 * tree-vect-slp.c (vect_bb_vectorization_profitable_p): Fix condition under which to unset the visited flag. * g++.dg/torture/pr102142.C: New testcase.
