The boolean reinterpret intrinsics, including __riscv_vreinterpret_v_u8m1_b8, are a somewhat recent addition, and aren't available in either GCC 13.2 or clang 16. It is however available in trunk of both; https://godbolt.org/z/bWvnTfGfM

Also, you might want something like __riscv_vmsne_vx_i8m1_b8(vand_m, 0, 32) instead; the reinterpret will reinterpret (giving 8 bits per each int8 element here) whereas a comparison will give 1 mask bit per element.

okay, I thought vreinterpret will also be 1-bit, I will then use the __riscv_vmsne_vx_i8m1_b8(vand_m, 0, 32) instead.
Thank you so much!
