The following makes sure we have a corresponding mask available. There's no good way to distinguish loop masking from len masking here, so assume we have recorded a mask for the operands mask producers. PR tree-optimization/121059 * tree-vect-stmts.cc (vectorizable_operation): Record a loop mask for mask AND operations. * gcc.dg/vect/pr121059.c: New testcase.
