I don't think so: write(); fence(Release); store() under those rules would imply that the write() is Release when in-fact the store() might be the one that is used to observe the contents of the write(), meaning the store() would have to be Release.
"Promoting the store() to Release" might be the wrong imagery to use on my part. The C++ Atomics Reference describes it much more concretely:
A release fence F in thread A synchronizes-with atomic acquire operation Y in thread B, if:
there exists an atomic store X (with any memory order)
F is sequenced-before X in thread A
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
