tree-scalar-evolution.c: Document instantiate_scev.
2008-05-09 Jan Sjodin <jan.sjodin@amd.com>
Sebastian Pop <sebastian.pop@amd.com>
* tree-scalar-evolution.c: Document instantiate_scev.
(instantiate_parameters_1): Renamed instantiate_scev_1.
Don't use the same loop for instantiation_loop and evolution_loop.
(instantiate_scev): New.
(instantiate_parameters): Moved...
(resolve_mixers): Update call to instantiate_scev_1 to pass the
same loop twice. Maintains the semantics for this function.
* tree-scalar-evolution.h (instantiate_scev): Declare.
(instantiate_parameters): ...here. Now static inline.
* tree-data-ref.c (dr_analyze_indices): Call instantiate_scev
instead of resolve_mixers.
