1. Add two defined marco LIBYUV_RVV_HAS_TUPLE_TYPE & LIBYUV_RVV_HAS_VXRM_ARG Intrinsic v0.12 introduces - tuple type in segment load & store - vxrm argument in fixed-point intrinsics (e.g vnclip) These two marcos are controled by __riscv_v_intrinsic. 2. Support RVV v0.12 intrinsics in row_rvv.cc & scale_rvv.cc Change-Id: I921f91d9dc8fdda031e7b6647d0e296aa2793c39 Signed-off-by: Bruce Lai <bruce.lai@sifive.com> Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/4767120 Reviewed-by: Frank Barchard <fbarchard@chromium.org>
