I will note that there are some helper functions, e.g. tcg_gen_vec_add16_i64
(see the end of include/tcg/tcg-op-gvec.h), but those are explicitly i64, and
you'll still need these for rv32.
Hi Richard,
Yes, that's really what I need.
Do you mind continue to review the other patches in v1? Or should I
send a v2 to fix current error at first?
