[FFmpeg-devel] [PATCH 3/3] avcodec/hevc: Add wasm simd128 idct

From: Zhao Zhili We don't use intrinsics normally for performance reasons. However, WASM isn't machine instruction. I suspect that in this scenario, handwritten assembly may not bring much performance compared with intrinsics. And I don't want to dig into the WASM ABI. So this patch is implemente
