Support atomic_fence instrinstic #972
Description
I'd love to try miri on evmap, but sadly I get the following error:
error[E0080]: Miri evaluation error: unimplemented intrinsic: atomic_fence --> /home/jon/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/libcore/sync/atomic.rs:2412:23 | 2412 | SeqCst => intrinsics::atomic_fence(), | ^^^^^^^^^^^^^^^^^^^^^^^^^^ Miri evaluation error: unimplemented intrinsic: atomic_fence | note: inside call to `std::sync::atomic::fence` at src/write.rs:306:9 --> src/write.rs:306:9 | 306 | atomic::fence(atomic::Ordering::SeqCst); | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Is this a known issue? Some cursory searching did not yield anything that seemed relevant.
