Callable Signatures

namespace eve
{
   // Regular overloads
   constexpr auto bit_notand(value auto x, value auto ... xs)                          noexcept; // 1
   constexpr auto bit_notand(kumi::non_empty_product_type auto const& tup)             noexcept; // 2
 
   // Lanes masking
   constexpr auto bit_notand[conditional_expr auto c](/*any of the above overloads*/)  noexcept; // 3
   constexpr auto bit_notand[logical_value auto m](/*any of the above overloads*/)     noexcept; // 3
}

Parameters

• x: first argument.
• xs...: other arguments.
• tup: non empty tuple of arguments.
• c: Conditional expression masking the operation.
• m: Logical value masking the operation.

Return value

1. The return value type is the common bit_value of the parameters. Each parameter is converted to this type and then:
   • For two parameters it computes the bitwise NOTAND of the two parameters
   • For more than two parameters the call is semantically equivalent to bit_notand(a0, bit_and(xs...))
2. equivalent to the call on the elements of the tuple.
3. The operation is performed conditionnaly. This is only supported when all parameters share the same number of lanes or are scalars.
