poly_int: REG_OFFSET
This patch changes the type of the reg_attrs offset field from HOST_WIDE_INT to poly_int64 and updates uses accordingly. This includes changing reg_attr_hasher::hash to use inchash. (Doing this has no effect on code generation since the only use of the hasher is to avoid creating duplicate objects.) 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (reg_attrs::offset): Change from HOST_WIDE_INT to poly_int64. (gen_rtx_REG_offset): Take the offset as a poly_int64. * inchash.h (inchash::hash::add_poly_hwi): New function. * gengtype.c (main): Register poly_int64. * emit-rtl.c (reg_attr_hasher::hash): Use inchash. Treat the offset as a poly_int. (reg_attr_hasher::equal): Use must_eq to compare offsets. (get_reg_attrs, update_reg_offset, gen_rtx_REG_offset): Take the offset as a poly_int64. (set_reg_attrs_from_value): Treat the offset as a poly_int64. * print-rtl.c (print_poly_int): New function. (rtx_writer::print_rtx_operand_code_r): Treat REG_OFFSET as a poly_int. * var-tracking.c (track_offset_p, get_tracked_reg_offset): New functions. (var_reg_set, var_reg_delete_and_set, var_reg_delete): Use them. (same_variable_part_p, track_loc_p): Take the offset as a poly_int64. (vt_get_decl_and_offset): Return the offset as a poly_int64. Enforce track_offset_p for parts of a PARALLEL. (vt_add_function_parameter): Use const_offset for the final offset to track. Use get_tracked_reg_offset for the parts of a PARALLEL.
