--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Fri Apr 17 16:43:28 2015 New Revision: 222186 URL: https://gcc.gnu.org/viewcvs?rev=222186&root=gcc&view=rev Log: PR target/65689 * genpreds.c (struct constraint_data): Add maybe_allows_reg and maybe_allows_mem bitfields. (maybe_allows_none_start, maybe_allows_none_end, maybe_allows_reg_start, maybe_allows_reg_end, maybe_allows_mem_start, maybe_allows_mem_end): New variables. (compute_maybe_allows): New function. (add_constraint): Use it to initialize maybe_allows_reg and maybe_allows_mem fields. (choose_enum_order): Sort the non-is_register/is_const_int/is_memory/ is_address constraints such that those that allow neither mem nor reg come first, then those that only allow reg but not mem, then those that only allow mem but not reg, then the rest. (write_allows_reg_mem_function): New function. (write_tm_preds_h): Call it. * stmt.c (parse_output_constraint, parse_input_constraint): Use the generated insn_extra_constraint_allows_reg_mem function instead of always setting *allows_reg = true; *allows_mem = true; for unknown extra constraints. * gcc.target/aarch64/c-output-template-4.c: New test.
