- MSAN fails on most inline assembly, unaware of what the load and store instructions do. - MSAN is also failing on row_any functions, which memcpy a correct number of pixels into a buffer that is SIMD vector sized, apply SIMD to the full vector, and then memcpy the exact number of resulting pixels to the output buffer. MSAN wants the temporary buffer to be initialized. Which genenerally is done with a memset(buf, 0, sizeof(buf)); to satisify MSAN. - RVV may not require disabling MSAN, since row functions are all 'any' number of elements, and implementation is intrinsics.
