* reload.c (find_reloads): Handle constraint letters marked by EXTRA_ADDRESS_CONSTRAINT and EXTRA_MEMORY_CONSTRAINT. (alternative_allows_memconst): Likewise. * reload1.c (maybe_fix_stack_asms): Likewise. * recog.c (asm_operand_ok, preprocess_constraints, constrain_operands): Likewise. * regclass.c (record_operand_costs, record_reg_classes): Likewise. * local-alloc.c (block_alloc, requires_inout): Likewise. * stmt.c (parse_output_constraint, parse_input_constraint): Likewise. * defaults.h (EXTRA_MEMORY_CONSTRAINT): Provide a default. (EXTRA_ADDRESS_CONSTRAINT): Likewise. * doc/tm.texi: Document these two new target macros. * config/s390/s390.c (s390_expand_plus_operand): Accept already valid operands. (q_constraint): New function. config/s390/s390-protos.h (q_constraint): Declare it. config/s390/s390.h (EXTRA_CONSTRAINT): Use it. (EXTRA_MEMORY_CONSTRAINT): New macro. * config/s390/s390.md: Throughout the machine description, replace all instances of the constraint combinations 'Qo' or 'oQ' with simply 'Q'. From-SVN: r56291
