According to packed_simd docs, the syntax for simd_shuffle4() is as follows: "The indices must be in range [0, M * N) where M is the number of input vectors (1 or 2)and N is the number of lanes of the input vectors. The indices i in range [0, N) refer to the i-th element of vec0, while the indices in range [N, 2*N) refer to the i - N-th element of vec1." I did not find implementation or documentation for simd_shuffle4() but I believe packed_simd implements exactly the same interface. Plus, implementing this change has fixed font-kit glyph output on an Apple M1 mac (64-bit arm). |
