From 1b5f0fc8dfdad74649d4e12737c83e727e116535 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sun, 17 Aug 2014 21:29:40 +0200 Subject: [PATCH] arch: add an option to specify if the arch has atomic ops The fact that atomic operations are available is not really a specificity of the toolchain, but rather of the architecture. So, add a new option that architectures that have atomic operations can select. This in turn selects the current toolchain atomic option, until all packages have been converted, at which point the old toolchain option can be removed.
