Hi,
The attached patch adjusts vec_perm_const hook to accommodate the new parameter.
For rationale, please see:
https://gcc.gnu.org/pipermail/gcc-patches/2022-May/595128.html
OK to commit if bootstrap+test passes ?

Thanks,
Prathamesh

Formatting nit: long line.

Patch is OK with the parameters reflowed, like you did for aarch64.

Same nit for some of the other patches (but some are OK as-is).
OK for 2-8 with that fixed.

Thanks,
Richard
