◆ make_array()

template<class T , std::size_t N>
CELER_CONSTEXPR_FUNCTION auto celeritas::make_array ( LdgSpan< T, N > const &  s)

Construct an array from a fixed-size span, removing LdgValue marker.

Note:

make_array(Span<T,N> const&)
CELER_CONSTEXPR_FUNCTION auto make_array(Span< T, N > const &s)
Construct an array from a fixed-size span.
Definition: Span.hh:240

is not reused because:

  1. Using this overload reads input data using __ldg
  2. return make_array<T, N>(s)
    results in segfault (gcc 11.3). This might be a compiler bug because temporary lifetime should be extended until the end of the expression and we return a copy...
