Author: matz Date: Tue Jan 19 16:05:57 2010 New Revision: 156043 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=156043 Log: PR tree-optimization/41783 * tree-data-ref.c (toplevel): Include flags.h. (dump_data_dependence_relation): Also dump the inputs if the result will be unknown. (split_constant_offset_1): Look through some conversions. * tree-predcom.c (determine_roots_comp): Restart a new chain if the offset from last element is too large. (ref_at_iteration): Deal also with MISALIGNED_INDIRECT_REF. (reassociate_to_the_same_stmt): Handle vector registers. * tree-vect-data-refs.c (vect_equal_offsets): Handle unary operations (e.g. conversions). * tree-vect-loop-manip.c (vect_gen_niters_for_prolog_loop): Add wide_prolog_niters argument, emit widening instructions. (vect_do_peeling_for_alignment): Adjust caller, use widened variant of the iteration cound. * Makefile.in (tree-data-ref.o): Add $(FLAGS_H). testsuite/ * gfortran.dg/vect/fast-math-mgrid-resid.f: New.
