Are all CPU superset features which accord to -m options automatically put and set by gcc when gcc has -march=native (or specific else), if no, how a convenient way to put them automatically ? as on GCC doc. eg -march=bdever1 has supersets FMA4, AVX, XOP, LWP, AES, PCLMUL, CX16, MMX, SSE, SSE2, SSE3, SSE4A, SSSE3, SSE4.1, SSE4.2, ABM and 64-bit instruction set extensions the features which accord to e.g. -m option of -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2 how to automatically conveniently put ie. set them all ?
