	* config/tc-msp430.c (CHECK_RELOC_MSP430): Add OP parameter.
	Generate BFD_RELOC_MSP430_ABS_HI16 if vshift is 1.
	(msp430_srcoperand): Store vshift value in operand.

	* msp430.h (struct msp430_operand_s): Add vshift field.

	* gas/elf/struct.d: Expect extra output from some toolchains.
	* gas/symver/symver0.d: Likewise.
	* gas/symver/symver1.d: Likewise.
