b3625fe62c * config/tc-m68k.c (parse_mri_control_operand): Change leftstart
and rightstart to not be const.
	(parse_mri_control_expression): Likewise.
	(build_mri_control_operand): Likewise.  If the left side of the
	comparison is a register, and the right side is not, swap the two
	sides.
	* config/m68k-parse.y (m68k_reg_parse): Make globally visible.
	* config/m68k-parse.h (m68k_reg_parse): Declare.

27a53b88d7 * config/tc-m68k.c (m68k_float_copnum): New static variable.
(md_pseudo_table): Add fopt and mask2.
	(m68k_ip): Use m68k_float_copnum, not COPNUM, when setting
	coprocessor register to use.  In case 'I' when checking operands,
	correct coprocessor register numbers.  In case 'I' when setting
	operands, don't add 1.
	(s_fopt): New static function.
	* config/m68k-parse.h (COPNUM): Don't define.

a1c7c0f3ac * config/m68k-parse.y: New file: bison grammar for m68k operands,
including support for Motorola syntax.
	* config/m68k-parse.h: New file; definitions shared between
	m68k-parse.y and tc-m68k.c.
	* config/tc-m68k.c: Include m68k-parse.h.
	(enum operand_type): Move to m68k-parse.h, where it is named
	m68k_operand_type.  Rename all uses.  Rearrange somewhat.  Add
	FPREG.  Rename AOFF to DISP.  Rename AINDX to BASE.  Rename APODX
	to POST.  Rename APRDX to PRE.  Remove AMIND.  Rename MSCR to
	CONTROL.  Remove DINDR.
	(struct m68k_exp): Move to m68k-parse.h.  Remove e_beg, e_end and
	e_seg fields.  Rename e_exp to exp.  Rename e_siz to size, and
	change type to enum m68k_size.  Change all uses.
	(enum _register): Move to m68k-parse.h, where it is named
	m68k_register.  Rename all uses.  Add ZDATA0-7 and ZADDR0-7.
	(struct m68k_op): Move to m68k-parse.h.  Change all fields.
	(seg): Don't define.
	(add_exp): Remove.
	(FAIL, OK): Remove.
	(m68k_reg_parse): Move to m68k-parse.y, and rewrite.
	(SKIP_WHITE, SKIP_W): Remove.
	(try_moto_index, try_index): Remove.
	(m68k_ip_op): Move to m68k-parse.y, and rewrite to use grammar.
	(main): Remove obsolete test function.
	(m68k_ip): Extensive changes to use new grammar.
	(get_regs): Remove.
	(crack_operand): m68k_ip_op now returns 0 on success.
	(init_table): Add ssp, zd0-7 and za0-7.
	(md_assemble): Make er const.  Correct loop over operands when
	looking for error message.
	(md_begin): Set alt_notend_table for '(' and '@'.
	(get_num): Expression is already parsed.  Don't set seg.
	* configure.in: If cpu_type is m68k, put m68k-parse.o in
	extra-objects.
	* configure: Rebuild.
	* Makefile.in (DISTSTUFF): Add m68k-parse.c.
	(BISON): Use ../bison/bison if it exists.
	(BISONFLAGS): Define as empty.
	(TARG_CPU_DEP_m68k): Depend upon $(srcdir)/config/m68k-parse.h.
	(m68k-parse.c, m68k-parse.o): New targets.
