Callable Signatures

namespace eve
{
   // Regular overloads
   constexpr auto bit_xor(value auto x, value auto ... xs)                          noexcept; // 1
   constexpr auto bit_xor(kumi::non_empty_product_type auto const& tup)             noexcept; // 2
 
   // Lanes masking
   constexpr auto bit_xor[conditional_expr auto c](/*any of the above overloads*/)  noexcept; // 3
   constexpr auto bit_xor[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 value of the bitwise XOR of its arguments converted to their common bit_value is returned.
2. equivalent to the call on the elements of the tuple.
3. The operation is performed conditionnaly.
