From: Andrea Parri Date: Sat, 1 Dec 2018 00:01:56 +0000 (+0100) Subject: riscv, atomic: Add #define's for the atomic_{cmp,}xchg_*() variants X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8b699616f399b58071cda41e5a1125d8480ac982;p=openwrt%2Fstaging%2Fblogic.git riscv, atomic: Add #define's for the atomic_{cmp,}xchg_*() variants If an architecture does not define the atomic_{cmp,}xchg_*() variants, the generic implementation defaults them to the fully-ordered version. riscv's had its own variants since "the beginning", but it never told (#define-d these for) the generic implementation: it is time to do so.
