2010-09-09 Sebastian Pop <sebastian.pop@amd.com>
* Makefile.in (OBJS-common): Add graphite-flattening.o.
(graphite-flattening.o): New rule.
* common.opt (floop-flatten): New flag.
* doc/invoke.texi (-floop-flatten): Documented.
* graphite-flattening.c: New.
* graphite-poly.c (apply_poly_transforms): Call flatten_all_loops.
* graphite-poly.h (flatten_all_loops): Declared.
(lst_remove_loop_and_inline_stmts_in_loop_father): New.
