* config/rx/rx.opt (mallow-string-insns): New option.
* config/rx/rx.c (RX_BUILTIN_RMPA): Disable the use of this
builtin if string instructions are denied.
* config/rx/rx.h (TARGET_CPU_CPP_BUILTINS): Define
__RX_ALLOW_STRING_INSNS__ or __RX_DISALLOW_STRING_INSNS__, as
appropriate.
(ASM_SPEC): Pass -mno-allow-string-insns on to the assembler.
* config/rx/rx.md (movstr): Enable pattern only if string
instructions are allowed.
(rx_movstr, rx_strend, movmemsi, rx_movmem): Likewise.
(cmpstrnsi, cmpstrsi, rx_cmpstrn, rmpa): Likewise.
* config/rx/t-rx (MULTILIB_OPTIONS): Add mno-allow-string-insns.
(MULTILIB_DIRNAMES): Add no-strings.
* doc/invoke.texi: Document -mno-allow-string-insns.
* gcc.target/rx/builtins.c: Disable RMPA test if string
instructions are not allowed.
