--- Comment #1 from bin.cheng <amker.cheng at gmail dot com> ---
The patch can fix the issue, but problem is why GCC/lra generated
register-indexing ([reg+reg]) addressing mode for V8HImode in the first place.
Since without this patch, the address expression is illegal and shouldn't be
generated. I didn't look into LRA's code and am not very sure whether this
patch is covering the problem.
Also added Marcus and Vlad to the CC list.
