# Results so far
The plan 9 system already uses SSE instructions for FP operations, but they are all based on the `*SD` (scalar double-precision) subset. The tests suffixed by `_sse` below use instructions from the `*PD` (packed double-precision) subset, which perform actual SIMD operations over the data using the 128-bit XMM registers. Those suffixed by `_avx` do the same but using AVX instructions that operate with the 256-bit wide YMM registers, even when performing 128-bit operations. The trailing `_a` means the tests are run loading from memory-aligned operands, conforming to the requirements of each instruction.
