One of the checks done in\neach case was verifying that the compiler used was able to generate\nAVX code appropriately. However, since this was originally done,\nour minimum compiler support has been updated and so we no longer\nneed to check this - all supported compilers can generate AVX2.\nThis allows us to simplify the build logic for the x86 vector code.\n\nIn future, we can do similarly for AVX-512.\n\nBruce Richardson (2):\n build/x86: remove conditional checks for AVX2 support\n build: remove unnecessary AVX2 compiler flag\n\n drivers/net/bnxt/bnxt_ethdev.c | 8 ++++----\n drivers/net/bnxt/bnxt_rxr.h | 2 +-\n drivers/net/bnxt/bnxt_txr.h | 2 +-\n drivers/net/bnxt/meson.build | 26 +++++++++----------------\n drivers/net/enic/meson.build | 10 +++-------\n drivers/net/i40e/i40e_rxtx.c | 14 ++++---------\n drivers/net/i40e/meson.build | 22 ++++++---------------\n drivers/net/iavf/iavf_rxtx_vec_common.h | 2 +-\n drivers/net/iavf/meson.build | 22 ++++++---------------\n drivers/net/ice/meson.build | 21 ++++++--------------\n lib/acl/meson.build | 23 +++++-----------------\n lib/acl/rte_acl.c | 10 +++-------\n 12 files changed, 49 insertions(+), 113 deletions(-)\n\n--\n2.39.2" }
