re PR fortran/92094 (ice in vect_transform_stmt at tree-vect-stmts.c:10921)
2019-10-15 Richard Biener <rguenther@suse.de>
PR tree-optimization/92094
* tree-vect-loop.c (vectorizable_reduction): For nested cycles
do not adjust the reduction definition def type.
* tree-vect-stmts.c (vect_transform_stmt): Verify the scalar stmt
defines the latch argument of the PHI.
* gfortran.dg/pr92094.f90: New testcase.
