Seriously? > Thanks for the update, that's good to know Apple's antediluvian assembler doesn't yet support AVX instructions. Actually, now that I look at it, looks like GCC didn't support AVX until 4.6.0. We'll put in a check disabling AVX if CMake doesn't find GCC 4.6. Unfortunately, there's no safe way to enable AVX instructions without using xgetbv. --n > > > _______________________________________________ > Discuss-gnuradio mailing list > [email protected] > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio >
