re PR target/14547 (Passing _Complex long double does not follow the ABI)
PR target/14547 * target.h (struct gcc_target): Move calls substructure before booleans. Add split_complex_arg. * function.c (assign_parms, split_complex_args): Use it. * calls.c (expand_call): Likewise. (split_complex_values): Likewise. Check for splittable types before allocating memory. (split_complex_types): Likewise. * system.h (SPLIT_COMPLEX_ARGS): Poison. * expr.h (SPLIT_COMPLEX_ARGS): Remove. * target-def.h (TARGET_SPLIT_COMPLEX_ARG): New. * config/alpha/alpha.c (alpha_split_complex_arg): New. (TARGET_SPLIT_COMPLEX_ARG): New. * config/alpha/alpha.h (SPLIT_COMPLEX_ARGS): Remove. * config/rs6000/rs6000.c (TARGET_SPLIT_COMPLEX_ARG): New. (rs6000_override_options): Zap it for non-AIX. (rs6000_function_value): Use targetm.calls.split_complex_arg. * config/rs6000/rs6000.h (SPLIT_COMPLEX_ARGS): Remove. * config/xtensa/xtensa.c (TARGET_SPLIT_COMPLEX_ARG): New. * config/xtensa/xtensa.h (SPLIT_COMPLEX_ARGS): Remove. * doc/tm.texi (TARGET_SPLIT_COMPLEX_ARG): Modify from old SPLIT_COMPLEX_ARGS entry.
