--- Comment #3 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
This is caused by SRA scalarizing the structural registers. i.e. it breaks
apart the uint8x16x2_t into two uint8x16_t, for use with vld2 we need them as a
whole, and so we recreate the type again.
This causes a copy through scalarization and then constructing the type again
in RTL. Reload is able to remove one copy but not the other.
The fix for #106106 will also fix this.
