* config/rx/rx.c (rx_function_arg_boundary): When using the RX ABI
align stack arguments to their natural alignment.
(rx_narrow_volatile_bitfield): New function. Allows narrow
volatile bitfields.
(rx_ok_to_inline): New function. Do not inline functions with
local variables into a naked caller.
(TARGET_NARROW_VOLATILE_BITFIELD): Define.
(TARGET_CAN_INLINE_P): Define.
* config/rx/rx.c (TARGET_CPU_CPP_BUILTINS): Define __RX_ABI__ or
__RX_GC_ABI__.
(ASM_SPEC): Pass -mgcc-abi on to the assembler.
(STRICT_ALIGNMENT): Set to false.
(CTORS_SECTION_ASM_OP): Add executable attribute.
(DTORS_SECTION_ASM_OP): Add executable attribute.
(INIT_ARRAY_SECTION_ASM_OP): Add executable attribute.
(FINI_ARRAY_SECTION_ASM_OP): Add executable attribute.
* config/rx/rx.md (subdi3): Don't allow MEMs as the third operand,
as it causes too much reload pressure.
* config/rx/rx.opt (mgcc-abi): New option.
(mrx-abi): New option.
* config/rx/t-rx (MULTILIB_OPTIONS): Show how to add an ABI
multilib.
(MULTILIB_DIRNAMES): Likewise.
