	gcc/
	* config/mips/mips.c (mips_attribute_table): Add "near" and "far"
	function attributes, "far" being an alias for "long_call".
	(TARGET_COMP_TYPE_ATTRIBUTES): Define as mips_comp_type_attributes.
	(mips_near_type_p, mips_far_type_p): New.
	(mips_comp_type_attributes): New function to check that attributes
	attached to a function type are compatible.
	(mips_output_mi_thunk): Test SYMBOL_REF_LONG_CALL_P() rather than
	TARGET_LONG_CALLS when deciding	whether we can do a direct sibcall
	to the target function of the thunk.
	(mips_encode_section_info): Check for "near" and "far" function
	attributes, and always set the SYMBOL_FLAG_LONG_CALL bit explicitly.

	* config/mips/predicates.md (const_call_insn_operand): Test only
	SYMBOL_REF_LONG_CALL_P() and not TARGET_LONG_CALLS.

	* doc/extend.texi (Function Attributes): Document MIPS "near" and
	"far" attributes.

	* testsuite/gcc.target/mips/near-far-1.c:  New test case.
