libcu++ 1.7.0 (CUDA Toolkit 11.6)

libcu++ 1.7.0 is a major release. It adds cuda::std::atomic_ref for integral
types. cuda::std::atomic_ref may potentially replace uses of CUDA specific
atomicOperator(_Scope) calls and provides a singular API for host and device code.

Supported ABI Versions: 4 (default), 3, and 2.

New Features

  • #203 Implements cuda::std::atomic_ref for integral types.

Issues Fixed

  • #204: Fallback macro backend in <nv/target> when C or pre-C++11 dialects are used.
  • #206: Fix compilation with ASAN enabled.
    • Thanks Janusz Lisiecki for this contribution.

  • #217: Fix how CUDACC version is calculated for __int128 support.
  • #228: Fix LLVM lit pattern matching in test score calculation.
  • #227: Silence 4296 for type_traits.
  • #225: Fix calculation of _LIBCUDACXX_CUDACC_VER broken from #217.
    • Thanks Robert Maynard for this contribution.
  • #220: memcpy_async should cache only in L2 when possible.
  • #219: Change atomic/atomic_ref ctors to prevent copy construction.
