From c0362128c57a0ad22ea311a9657bb15a44b70793 Mon Sep 17 00:00:00 2001 From: Adrien Mazarguil Date: Mon, 29 Jun 2015 11:34:52 +0200 Subject: [PATCH] eal: fix pedantic build of mlx4 debug mode Since the commit below includes rte_cpuflags.h in rte_spinlock.h, compilation of the mlx4 driver fails when CONFIG_RTE_LIBRTE_MLX4_DEBUG=y. This mode adds -pedantic to the compiler's command line for mlx4, which complains about the static definition of an empty cpu_feature_table[] in common rte_cpuflags.h, then about its redefinition as a larger array in arch-specific rte_cpuflags.h. While DPDK does not officially support -pedantic internally, external applications may enable it and include rte_spinlock.h from the public API. Instead of removing -pedantic from mlx4, this commit fixes rte_cpuflags.h.
