Then converts RTE_BUILD_BUG_ON() with static_assert. static_assert() is more picky about the expression has to be a constant, which also catches some existing undefined behavior that pre-existed. v4 - incorporate review feedback add RTE_MIN_T and RTE_MAX_T macros Stephen Hemminger (6): eal: introduce RTE_MIN_T() and RTE_MAX_T() macros event/opdl: fix non-constant compile time assertion net/sfc: fix non-constant expression in RTE_BUILD_BUG_ON() net/i40e: avoid using const variable in assertion mempool: avoid floating point expression in static assertion eal: replace out of bounds VLA with static_assert drivers/event/opdl/opdl_ring.c | 2 +- drivers/net/i40e/i40e_ethdev.h | 1 + drivers/net/i40e/i40e_rxtx_vec_sse.c | 10 ++++------ drivers/net/mlx5/mlx5_rxq.c | 2 +- drivers/net/sfc/sfc_ef100_tx.c | 4 +--- lib/eal/include/rte_common.h | 19 ++++++++++++++++++- lib/mempool/rte_mempool.c | 7 ++++--- 7 files changed, 30 insertions(+), 15 deletions(-)
