  1. [Xcode] Don’t use a bridging header in a framework target 

    Oops, that was not intended to work, and in fact it produces warnings in clients.

Instead, change _sa_retain_n and _sa_release_n to Swift calling convention and call them using _silgen_name trickery when in single-module configuration.

  1. [_AtomicsShims] Don’t define atomic operations when this header is co… 

    …mpiled as C++

`_Atomic(_sa_dword)` trips up C++. This is likely due to real issues, but it seems pointless to try to fix it — rather than heroically trying to keep this header working, we can simply force the use of native builtins on Swift 5.9 and later. (I planned to do that anyway, as a major step towards deleting `_AtomicsShims` altogether.)

  1. [_AtomicShims] On Darwin, ensure we link against libswiftCore using a… 

    …ssembly shenanigans

This avoids a linker failure when the build system decides to build this module as a standalone library.

Hopefully this will all go away soon, when swift_retain_n/swift_release_n will become primitives exposed by the stdlib.

The SysV ABI defined uint64_t with 4 byte alignment on i386 — so we can’t just assume that the integer types will have the right alignment by default for atomics.

Emulate the original `_Atomic<Width>Storage` types in the C shims even in native atomics configuration, so that they can carry a custom `@_alignment` attribute.

- Swift 5.8 release series
- Swift 5.7 release series

We also aim to support building and using swift-atomics on developer snapshots of Swift’s active branches (release/5.10 and main).

  2. Let builtins & shims expose different primitive signatures 

    For builtins, we want to emulate the stdlib’s solution where all atomic primitive operations take and return a (sort of) opaque atomic representation value.

For C shims, we do not want to atomic primitives to take and return _Atomic(T) values, so let’s revert to the original 1.1.x solution.

  1. Avoid confusing Swift 5.7 with _pointerBitWidth conditionals 

    #if conditional parsing is evidently broken in 5.7, and it gets confused unless things are arranged just right. Things seem to work as long as the `compiler(>=5.9)` conditional is put on its own `#if` construct on the topmost level — so let’s do that for now.

  2. On 5.9, hide the _AtomicsShims import from the public interface 

    This appears to resolve a build failure when library evolution is enabled. (This isn’t a fully supported configuration (this package is not ABI stable), but it should still be possible to build the package in that configuration.)

@_implementationOnly has bad failure modes when library evolution isn’t enabled, but I hope we’ll be avoiding those here, as on 5.9+, we’re only using it to import a couple of functions — we aren’t relying on imported things to set struct layouts or anything like that. 🤞
