	* config/mips/mips.md (*lwxs): New.
	* config/mips/mips.opt (msmartmips): New.
	* config/mips/mips.c (mips_lwxs_address_p): New.
	(mips_rtx_costs): Make it recognize scaled indexed addressing.
	* config/mips/mips.h (TARGET_CPU_CPP_BUILTINS): Define
	__mips_smartmips when compiling for TARGET_SMARTMIPS.
	(ISA_HAS_ROR): Define for TARGET_SMARTMIPS.
	(ISA_HAS_LWXS): New.
	(ASM_SPEC): Add -msmartmips/-mno-smartmips.
	* doc/invoke.texi (MIPS Options): Document -msmartmips/-mno-smartmips.
	* testsuite/gcc.target/mips/smartmips-lwxs.c: New test case.
