Subject: question regarding div / std::div implementation
Date: Wed, 20 Apr 2016 19:44:00 -0000	[thread overview]
Message-ID: <CAF5HaEXKZ7j-gbZPiWPhDpx7=R0zm1xYvXNYCNUMG4WeZS532Q@mail.gmail.com> (raw)

Hi,

   is there any reason that std::div / cstdlib div is not implemented
in such a way that it is expanded to
the assembly instruction -when available- that calculates both the
remainder and the quotient,
e.g. x86' div ?

For example, why not an inline function with inline assembly? Or,
should this require a gcc built-in?

Thanks,

   Daniel.
