Progress

  • Clarify atomic bit validity rust-lang/rust#121943
  • Trait implementations
    • AtomicBool
      • KnownLayout
      • TryFromBytes / FromZeros
      • IntoBytes
      • Unaligned
    • AtomicU8, AtomicI8
      • KnownLayout
      • TryFromBytes / FromZeros / FromBytes
      • IntoBytes
      • Unaligned
    • AtomicUN / AtomicIN (N > 8)
      • KnownLayout
      • TryFromBytes / FromZeros / FromBytes
      • IntoBytes
    • AtomicPtr
      • KnownLayout
      • TryFromBytes / FromZeros
  • Support platforms for which target_has_atomics is spuriously false (see below)

Details

target_has_atomics

On some platforms, cfg(target_has_atomics) is disabled despite atomics support. For example, thumbv6m-none-eabi supports AtomicU32 but cfg(target_has_atomic = "32") is false on that platform. We will be able to support these cases once cfg(target_has_atomic_load_store) is stabilized.

Implement traits for atomic types

Makes progress on #1009. This commit doesn't implement all traits for
`AtomicPtr<T>`, so there's more work to do.
