/* md_parse_option
 *	Invocation line includes a switch not recognized by the base assembler.
 *	See if it's a processor-specific option.  These are:
 *
 *	-bump
 *		Warn on architecture bumps.  See also -A.
 *
 *	-Av6, -Av7, -Av8, -Asparclite, -Asparclet
 *		Standard 32 bit architectures.
 *	-Av8plus, -Av8plusa
 *		Sparc64 in a 32 bit world.
 *	-Av9, -Av9a
 *		Sparc64 in either a 32 or 64 bit world (-32/-64 says which).
 *		This used to only mean 64 bits, but properly specifying it
 *		complicated gcc's ASM_SPECs, so now opcode selection is
 *		specified orthogonally to word size (except when specifying
 *		the default, but that is an internal implementation detail).
 *	-xarch=v8plus, -xarch=v8plusa
 *		Same as -Av8plus{,a}, for compatibility with Sun's assembler.
 *
 *		Select the architecture and possibly the file format.
 *		Instructions or features not supported by the selected
 *		architecture cause fatal errors.
 *
 *		The default is to start at v6, and bump the architecture up
 *		whenever an instruction is seen at a higher level.  In 32 bit
 *		environments, v9 is not bumped up to, the user must pass
 * 		-Av8plus{,a}.
 *
 *		If -bump is specified, a warning is printing when bumping to
 *		higher levels.
 *
 *		If an architecture is specified, all instructions must match
 *		that architecture.  Any higher level instructions are flagged
 *		as errors.  Note that in the 32 bit environment specifying
 *		-Av8plus does not automatically create a v8plus object file, a
 *		v9 insn must be seen.
 *
 *		If both an architecture and -bump are specified, the
 *		architecture starts at the specified level, but bumps are
 *		warnings.  Note that we can't set `current_architecture' to
 *		the requested level in this case: in the 32 bit environment,
 *		we still must avoid creating v8plus object files unless v9
 * 		insns are seen.
 *
 * Note:
 *		Bumping between incompatible architectures is always an
 *		error.  For example, from sparclite to v9.
