	* config/rs6000/rs6000.c (rs6000_function_arg): Remove CALL_LIBCALL
	when returning call_cookie.
	(rs6000_function_ok_for_sibcall): Allow sibcalls via function
	pointers, to functions with no more vector args than the current
	function, and some non-local calls for ABI_V4.
	* config/rs6000/rs6000.md (sibcall_nonlocal_aix32,
	sibcall_nonlocal_aix64): Combine to ..
	(sibcall_nonlocal_aix<mode>): ..this.  Handle function pointer calls.
	(sibcall_value_nonlocal_aix32, sibcall_value_nonlocal_aix64): Combine..
	(sibcall_value_nonlocal_aix<mode>): ..likewise.
	(*sibcall_nonlocal_sysv<mode>): Handle function pointer calls.
	(sibcall_value_nonlocal_sysv<mode>): Likewise.  Correct call cookie
	operand.
	* config/rs6000/darwin.md (sibcall_nonlocal_darwin64,
	sibcall_value_nonlocal_darwin64, sibcall_symbolic_64,
	sibcall_value_symbolic_64): Delete.
gcc/testsuite/
	* gcc.target/powerpc/ppc-pow.c: Allow for tail calls.
