Callable Signatures

namespace eve
{
   // Regular overload
   constexpr auto minimum(value auto x)                          noexcept; // 1;
 
   // Lanes masking
   constexpr auto minimum[conditional_expr auto c](value auto x) noexcept; // 2
   constexpr auto minimum[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 minimal value of all lanes.
2. The minimal value of the retained lanes
