Change calls to cpp_parse_escape to match changes in cppexp.c (note hardcoded MASK, which is safe since this is the source character set). * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c to handle wide character constants in #if directives. The function now returns a HOST_WIDE_INT, and takes a third argument which is a binary mask for all legal values (0x00ff for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK.

Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg.

Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_used_at_all test, and remove stand-alone reload_reg_used_at_all test. Use reload_out_reg to determine which reload regs have output reloads. Treat reload_override_in more similar to inherited reloads. Handle (subreg (reg... for inheritance. For flag_expensive_optimizations, add an extra pass to remove unnecessary reloads from known working inheritance. Delete obsolete code for pseudos replaced with MEMs. Handle inheritance from auto_inc expressions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurrences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it.

(clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): Handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR.

(calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction.
