<pre>The following code triggers the `tautological-type-limit-compare` warning on
64bit.
--------------------------------------------------------------------
uint64_t size = get();
if constexpr(std::numeric_limits<decltype(size)>::max() >
std::numeric_limits<size_t>::max())
{
if(size > std::numeric_limits<size_t>::max())
return ReturnCode::outOfRange;
}
--------------------------------------------------------------------
To me this looks like a false positive. Alternatively, is there a "better" way
to express this?</pre>
