The existing __rte_packed macro is then used to restore the pack value prior to the push. Instead of providing macros exclusively for MSVC and for GCC the existing macro is deliberately utilized to trigger a warning if no existing packing has been pushed allowing easy identification of locations where the __rte_msvc_pack is missing. I've decided to only add the macro to packed structs that are built for Windows. It seems there is little value in adding the macro tree wide and if new code arrives that is built on Windows the __rte_packed will flag where the preamble macro is required. If as a part of review maintainers identify structs they believe don't require packing so long as they are explicitly identified i'll remove the __rte_packed as a part of this series. v4: * add another missing __rte_msvc_pack to crypto/mlx5 patch * correct commit message for duplicated packing packing in crypto/mlx5 patch v3: * add missing __rte_msvc_pack to crypto/mlx5 * fix commit messages to reference __rte_msvc_pack macro instead of __rte_msvc_pushpack(1) v2: * app/testpmd, remove packing from simple_gre_hdr * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata, simple_gre_hdr * examples, remove packing from pkt_key_qinq, pkt_key_ipv4_5tuple, pkt_key_ipv6_5tuple, pkt_key_ipv4_addr, pkt_key_ipv6_addr * eal, remove packing from rte_config, __rte_trace_stream_header Tyler Retzlaff (16): eal: provide pack start macro for MSVC eal: pack structures when building with MSVC net: pack structures when building with MSVC common/iavf: pack structures when building with MSVC common/idpf: pack structures when building with MSVC common/mlx5: pack structures when building with MSVC dma/ioat: pack structures when building with MSVC net/i40e: pack structures when building with MSVC net/iavf: pack structures when building with MSVC net/ice: pack structures when building with MSVC net/mlx5: pack structures when building with MSVC net/octeon_ep: pack structures when building with MSVC app/testpmd: pack structures when building with MSVC app/test: pack structures when building with MSVC examples: pack structures when building with MSVC crypto/mlx5: pack structures when building with MSVC app/test-pmd/csumonly.c | 2 +- app/test/test_efd.c | 1 + app/test/test_hash.c | 1 + app/test/test_member.c | 1 + drivers/common/iavf/iavf_osdep.h | 2 ++ drivers/common/iavf/virtchnl_inline_ipsec.h | 11 +++++++++++ drivers/common/idpf/base/idpf_osdep.h | 2 ++ drivers/common/mlx5/mlx5_common_mr.h | 4 ++++ drivers/common/mlx5/mlx5_common_utils.h | 1 + drivers/common/mlx5/mlx5_prm.h | 28 ++++++++++++++++++++++++++++ drivers/crypto/mlx5/mlx5_crypto.h | 1 + drivers/crypto/mlx5/mlx5_crypto_gcm.c | 1 + drivers/dma/ioat/ioat_hw_defs.h | 1 + drivers/net/i40e/base/i40e_osdep.h | 2 ++ drivers/net/iavf/iavf_ipsec_crypto.h | 4 +++- drivers/net/iavf/iavf_rxtx.c | 2 +- drivers/net/ice/base/ice_osdep.h | 2 ++ drivers/net/mlx5/hws/mlx5dr.h | 1 + drivers/net/mlx5/mlx5.h | 1 + drivers/net/mlx5/mlx5_flow.h | 5 +++++ drivers/net/mlx5/mlx5_hws_cnt.h | 1 + drivers/net/mlx5/mlx5_utils.h | 4 ++++ drivers/net/octeon_ep/otx_ep_mbox.h | 1 + examples/common/neon/port_group.h | 1 + examples/ip_pipeline/cli.c | 10 +++++----- examples/ipsec-secgw/ipsec.h | 1 + examples/l3fwd-power/main.c | 2 ++ examples/ptpclient/ptpclient.c | 8 ++++++++ lib/eal/common/eal_private.h | 2 +- lib/eal/include/rte_common.h | 4 +++- lib/eal/include/rte_memory.h | 1 + lib/eal/include/rte_memzone.h | 1 + lib/eal/include/rte_trace_point.h | 2 +- lib/eal/x86/include/rte_memcpy.h | 3 +++ lib/net/rte_arp.h | 2 ++ lib/net/rte_dtls.h | 1 + lib/net/rte_esp.h | 2 ++ lib/net/rte_ether.h | 1 + lib/net/rte_geneve.h | 1 + lib/net/rte_gre.h | 4 ++++ lib/net/rte_gtp.h | 5 +++++ lib/net/rte_ib.h | 1 + lib/net/rte_icmp.h | 3 +++ lib/net/rte_ip.h | 4 ++++ lib/net/rte_l2tpv2.h | 4 ++++ lib/net/rte_macsec.h | 2 ++ lib/net/rte_mpls.h | 1 + lib/net/rte_pdcp_hdr.h | 4 ++++ lib/net/rte_ppp.h | 1 + lib/net/rte_sctp.h | 1 + lib/net/rte_tcp.h | 1 + lib/net/rte_tls.h | 1 + lib/net/rte_udp.h | 1 + lib/net/rte_vxlan.h | 2 ++ 54 files changed, 145 insertions(+), 11 deletions(-) -- 1.8.3.1
