This patch changes the type of aff_tree::offset from widest_int to poly_widest_int and adjusts the function interfaces in the same way. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-affine.h (aff_tree::offset): Change from widest_int to poly_widest_int. (wide_int_ext_for_comb): Delete. (aff_combination_const, aff_comb_cannot_overlap_p): Take the constants as poly_widest_int rather than widest_int. (aff_combination_constant_multiple_p): Return the multiplier as a poly_widest_int. (aff_combination_zero_p, aff_combination_singleton_var_p): Handle polynomial offsets. * tree-affine.c (wide_int_ext_for_comb): Make original widest_int version static and add an overload for poly_widest_int. (aff_combination_const, aff_combination_add_cst) (wide_int_constant_multiple_p, aff_comb_cannot_overlap_p): Take the constants as poly_widest_int rather than widest_int. (tree_to_aff_combination): Generalize INTEGER_CST case to poly_int_tree_p. (aff_combination_to_tree): Track offsets as poly_widest_ints. (aff_combination_add_product, aff_combination_mult): Handle polynomial offsets. (aff_combination_constant_multiple_p): Return the multiplier as a poly_widest_int. * tree-predcom.c (determine_offset): Return the offset as a poly_widest_int. (split_data_refs_to_components, suitable_component_p): Update accordingly. (valid_initializer_p): Update call to aff_combination_constant_multiple_p. * tree-ssa-address.c (addr_to_parts): Handle polynomial offsets. * tree-ssa-loop-ivopts.c (get_address_cost_ainc): Take the step as a poly_int64 rather than a HOST_WIDE_INT. (get_address_cost): Handle polynomial offsets. (iv_elimination_compare_lt): Likewise. (rewrite_use_nonlinear_expr): Likewise.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
