--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm, I have to double check but I suspect the issue is there is no v4qi mode
for aarch64 currently but it could be added as emulated as basically v8qi
except load/store as s0.

Let me see if that helps there. The biggest thing is I have to make sure of=
 is
the abi does not change for vector(4) char too (the aarch64 backend uses mo=
de
in some cases still).=
