I'm not sure how it works for variable-length types but isn't
sizeof (vbool8_t) part of the ABI and thus its TYPE_SIZE / GET_MODE_SIZE
are relevant there? It might of course be that you can never have
these types as part of aggregates, arrays or objects of them address-taken
in
ks for variable-length types but isn't
sizeof (vbool8_t) part of the ABI and thus its TYPE_SIZE / GET_MODE_SIZE
are relevant there? It might of course be that you can never have
these types as part of aggregates, arrays or objects of them address-taken
in which case the issue is moot?

First we emit vsetvl e8mf8 +vsm for VNx1BI
Then we emit vsetvl e8mf8 + vlm for VNx2BI

So given the above I think that modeling the size as being the same
but with accurate precision would work. It's then only the size of the
padding in bytes we cannot represent with poly-int which should be fine.
Correct?

Actually, we just want to differentiate VNx1BI VNx2BI VNx4BI VNx8BI, and they
are considered the same in GCC which produce BUG in RVV currently.
This patch is j

Looks like you are busy and stuck in some important work right now, could you
please help to share something like ETA if possible? Then we may have a better
