Hi, Richard. >> Does IFN_COND_LEN make conceptual sense on RVV? If so, would defining >> it solve some of these problems? Yes, IFN_COND_LEN make sense to RVV. We have vmerge instruction which depending on VL/AVL.
I must say my internal RVV GCC has IFN_LEN_VCOND_MASK which simplify COND_LEN_ADD (mask, a, 0, b, len, bias) into LEN_VCOND_MASK (mask, a, b, len, bias) I think upstream GCC could consider this approach. Thanks. juzhe.zh...@rivai.ai
