Ok. Do you know why GCC prop load/store for arr into __riscv_vle8_v_u8m1?

Just because the __riscv_vle8_v_u8m1 pattern is complex?

I don't think we can simplify __riscv_vle8_v_u8m1 pattern since we tried to
fuse
all feature into a single pattern (A pattern includes multiple features bec=
ome
complex) to reduce the building of insn-emit.cc and insn-opinit.cc=
