Hi,

neg<mode>2 was described as only being applicable to modes
in the VDQM iterator. But the instruction generated, `NEG',
has a .2D form.

This patch corrects the iterator used to one including V2DImode.

Patch regression tested on aarch64-none-elf with no regressions.

OK?

Thanks,
James

	* config/aarch64/aarch64-simd.md (neg<mode>2): Use VDQ iterator.
