Subject: [dpdk-dev] [PATCH] eal/stack: fix 'pointer-sign' warning
Date: Sat, 15 Jun 2019 00:54:43 +0800
Message-ID: <1560531283-5229-1-git-send-email-phil.yang@arm.com> (raw)

clang raise 'pointer-sign' warnings in __atomic_compare_exchange
when passing 'uint64_t *' to parameter of type 'int64_t *' converts
between pointers to integer types with different sign.
