binutils-gdb/gas/configure.in
Ian Lance Taylor 5e65fbc84b Some support for PowerPC ELF, although it isn't in BFD yet. 
* configure.in: If cpu is powerpc*, use ppc.
	(ppc-*-sysv4*): Use object format elf.
	* config/tc-ppc.h: Only declare a number of things if OBJ_COFF is
	defined.
	(TARGET_ARCH): Make it call ppc_arch.
	(ppc_arch): Declare.
	(TARGET_FORMAT): Set based on OBJ_COFF or OBJ_ELF.
	(NO_STRING_ESCAPES): Define.
	(LOCAL_LABEL, FAKE_LABEL_NAME): Define for OBJ_ELF.
	* config/tc-ppc.c: Only define a number of functions of OBJ_COFF
	is defined.
	(md_pseudo_table): Most pseudo-ops are OBJ_COFF specific.  Added
	OBJ_COFF specific "bi" and "ei".
	(md_parse_option): Fix handling of -u.  Make -m601 set
	PPC_OPCODE_601.  If OBJ_ELF, accept -V and -Q.
	(ppc_set_cpu): New function.
	(ppc_arch): New function.
	(md_begin): Call ppc_set_cpu.
	(ppc_insert_operand): For a signed operand accept an unsigned
	value, for IBM compatibility.
	(ppc_byte): Don't call stringer for strings; instead, treat two
	double quotes as a single double quote.
	(ppc_comm): Set sy_tc.output for a .lcomm symbol.
	(ppc_biei): New function.
	(ppc_tc): If not OBJ_COFF, ignore first argument.
	(ppc_fix_adjustable): Call as_bad_where, not as_bad.
	(ppc_is_toc_sym): New function.
	(md_apply_fix): Use ppc_is_toc_sym.  Handle BFD_RELOC_16 and
	BFD_RELOC_8.
