From 73fe55d7522864d20026dc8d427026dc4078f9cc Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Wed, 6 Feb 2019 20:46:00 +0000 Subject: re PR go/89199 (libgo regression in implementation of CompareAndSwap functions resulting in intermittent testcase failures on ppc64le power9 after r268458) PR go/89199 sync/atomic: use strong form of atomic_compare_exchange_n In the recent change to use atomic_compare_exchange_n I thought we could use the weak form, which can spuriously fail. But that is not how it is implemented in the gc library, and it is not what the rest of the library expects. Thanks to Lynn Boger for identifying the problem.
