re PR tree-optimization/37482 (definition in block 51 follows the use for SSA_NAME with -maltivec)
PR tree-optimization/37482
* tree-vectorizer.h (struct _slp_instance): Add new field.
(SLP_INSTANCE_FIRST_LOAD_STMT): New.
(get_earlier_stmt): New function.
* tree-vect-analyze.c (vect_find_first_load_in_slp_instance): New
function.
(vect_analyze_slp_instance): Set SLP_INSTANCE_FIRST_LOAD_STMT.
* tree-vect-transform.c (vect_finish_stmt_generation): Remove the
asserts that GSI points to the scalar statement being vectorized.
Set new statement location according to GSI.
(vect_schedule_slp_instance): Use GSI of
SLP_INSTANCE_FIRST_LOAD_STMT when vectorizing loads.
