(cselib_set_value_sp_based, cselib_sp_based_value_p): New functions. * var-tracking.c (add_stores): Call cselib_set_value_sp_based for not yet preserved VALUEs of sp on sp assignments if hard_frame_pointer_adjustment != -1. (vt_initialize): When setting hard_frame_pointer_adjustment, disassociate sp from its previous value and call cselib_set_value_sp_based on a new VALUE created for sp. * gcc.dg/guality/pr54796.c: New test.
