Callable Signatures

namespace eve
{
   // Regular overload
   constexpr auto maximum(value auto x)                          noexcept; // 1;
 
   // Lanes masking
   constexpr auto maximum[conditional_expr auto c](value auto x) noexcept; // 2
   constexpr auto maximum[logical_value auto m](value auto x)    noexcept; // 2
}

Parameter

• x: argument.
• c: Conditional expression masking the operation.
• m: Logical value masking the operation.

Return value

1. The maximal value of all lanes.
2. The maximal value of the retained lanes.
