--- Comment #8 from Ramana Radhakrishnan <ramana at gcc dot gnu.org> --- Author: ramana Date: Wed Jun 24 09:59:28 2015 New Revision: 224890 URL: https://gcc.gnu.org/viewcvs?rev=224890&root=gcc&view=rev Log: Fix PR target/66200 This applies the same fix for PR target/66200 for AArch64 on the GCC 5 branch as on the 4.9 branch. On trunk we've fixed this differently by optimizing the access to the guard variable using a load acquire style instruction. 2015-06-24 Ramana Radhakrishnan <ramana.radhakrish...@arm.com> PR target/66200 * g++.dg/abi/aarch64_guard1.C: Adjust. 2015-06-24 Ramana Radhakrishnan <ramana.radhakrish...@arm.com> PR target/66200 * configure.host (host_cpu): Add aarch64 case. * config/cpu/aarch64/atomic_word.h: New file.
