* config/rs6000/tm-rs6000.h (IN_SOLIB_RETURN_TRAMPOLINE): Define.

	(rs6000_in_solib_return_trampoline): Declare.
	* rs6000-tdep.c (rs6000_in_solib_return_trampoline): New
	function.
	(rs6000_skip_trampoline_code): Skip bigtoc fixup code.
	* xcoffread.c (read_xcoff_symtab): Perform the ISFCN function
	check after the CSECT check rather than before it.  Allocate
	separate symtabs for CSECTs whose names begin with '@'.
	(scan_xcoff_symtab): Don't ignore symbols beginning with '@'.
	Activate the misc_func_recorded mechanism for whose names begin
	with '@'.
