Subject: [RFR] Store tearing
Date: Mon, 29 Oct 2018 00:06:27 +0100 [thread overview]
Message-ID: <20181028230627.GA3420@andrea> (raw)
Hi,
memory-barriers.txt says:
[on "store tearing"]
"In fact, a recent bug (since fixed) caused GCC to incorrectly use
this optimization in a volatile store.".
I was wondering if you could help me retrieve some reference/discussions
about this?
Thanks,
Andrea
