tree-vect-data-refs.c (vect_no_alias_p): New function.
* tree-vect-data-refs.c (vect_no_alias_p): New function.
(vect_prune_runtime_alias_test_list): Call vect_no_alias_p to
resolve alias checks which are known at compilation time.
Truncate vector LOOP_VINFO_MAY_ALIAS_DDRS(loop_vinfo) if all
alias checks are resolved. Move dump info for too many runtime
alias checks to here...
* tree-vect-loop.c (vect_analyze_loop_2): ...From here.
gcc/testsuite
* gcc.dg/vect/vect-35-big-array.c: Refine comment and test.
* gcc.dg/vect/vect-35.c: Ditto.
* gcc.dg/vect/vect-alias-check-2.c: New test.
