+       [BZ #16009]
+       * string/strxfrm_l.c (STRXFRM): Allocate fixed size cache for
+       weights and rules. Use do_xfrm_cached if data fits in cache,
+       do_xfrm otherwise.  Moved former main loop to...
+       * (do_xfrm_cached): New function.
+       * (do_xfrm): Non-caching version of do_xfrm_cached. Uses
+       find_idx, find_position and stack_push.
+       * (find_idx): New function.
+       * (find_position): Likewise.
+       * localedata/sort-test.sh: Added test run for do_xfrm.
+       * localedata/xfrm-test.c (main): Added command line option
+       -nocache to run the test with strings that are too large for
+       the STRXFRM cache.
