대충검색해봐도 아키텍쳐 설정은 없는데 SSE, MMX, AVX 관련 설정은 없는 것 같고
| -march=cpu-type Generate instructions for the machine type cpu-type. In contrast to -mtune=cpu-type, which merely tunes the generated code for the specified cpu-type, -march=cpu-type allows GCC to generate code that may not run at all on processors other than the one indicated. Specifying -march=cpu-type implies -mtune=cpu-type, except where noted otherwise. The choices for cpu-type are: ‘native’ This selects the CPU to generate code for at compilation time by determining the processor type of the compiling machine. Using -march=native enables all instruction subsets supported by the local machine (hence the result might not run on different machines). Using -mtune=native produces code optimized for the local machine under the constraints of the selected instruction set. ‘x86-64’ A generic CPU with 64-bit extensions, MMX, SSE, SSE2, and FXSR instruction set support. |

그렇다고 해서 -O2 까지만 보이니 vectorization은 지원안할꺼 같고...
| Vectorization in GCC is enabled at -O3. That's why at -O0, you see only the ordinary scalar SSE2 instructions (movsd, addsd, etc). |
