--- Comment #15 from HaoChen Gui <guihaoc at gcc dot gnu.org> ---
I drafted a patch to define separate expanders for V1TI. It works. I wonder if
I shall add V1TI into VEC_I and define an unified expander for V16QI V8HI V4SI
V2DI and V1TI. Also some insn patterns should be merged then. Please advice.
Thanks a lot.
