65d7bab591 This patch enhances the MSP430 port of GAS so that, if requested, it will
generate warning messages about an instruction that changes the interrupt
state not being followed by a NOP instruction.

	* config/msp430/msp430.c: Replace known mcu array with known
	msp430 ISA mcu name array.
	Accept any name for -mmcu option.
	Add -mz option to warn about missing NOP following an interrupt
	status change.
	(check_for_nop): New.
	(msp430_operands): Emit a warning, if requested, when an interrupt
	changing instruction is not followed by a NOP.
	* doc/c-msp430.c: Document -mz option.

	* gas/msp430/bad.d: Add -mz option.
	* gas/msp430/bad.s: Add more cases where warnings should be
	generated.
	* gas/msp430/bad.l: Add expected warning messages.

96b961024c Add .refsym to msp430 backend
* config/tc-msp430.c (msp430_refsym): New: ".refsym <symbol>"
* doc/c-msp430.texi (MSP430 Directives): Document it.

The purpose of this patch is to provide a way for one object file
to require the inclusion of another object, without having to
allocate space for a .word address reference.
