* config/tc-mips.c (PIC_CALL_REG, SP, FP): Define.

	* config/tc-mips.c (PIC_CALL_REG, SP, FP): Define.
	(mips_pic, mips_cprestore_offset): New static variables.
	(md_pseudo_table): Handle .abicalls, .cpload, and .cprestore.
	Ignore .bgnb and .endb.
	(gp_reference): _gp_disp is never addressed off GP.
	(macro_build): Ignore macros while searching for insn.  For cases
	i, j, and o, accept the reloc type as an argument rather than
	assuming BFD_RELOC_LO16.  Don't try to convert BFD_RELOC_LO16 to
	BFD_RELOC_MIPS_GPREL.  Added new case a.
	(set_at, load_register, macro): Changed calls to macro_build to
	pass new argument for i, j and o cases.
	(macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A.  These require
	special handling when generating SVR4 PIC code.
	(mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
	rather than hard coded constants.
	(md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and
	BFD_RELOC_MIPS_CALL16.
	(s_option): Set mips_pic based on .option picN.
	(s_abicalls): New function; set mips_pic to 2.
	(s_cpload): New function; handle .cpload.
	(s_cprestore): New function; handle .cprestore.

	* config/obj-ecoff.c (obj_pseudo_table): Add entries for .bgnb,
	.endb and .verstamp, setting them to s_ignore.
