>From 9ccffd30d2f3fbc5e35e5ce445834c53d1d2a4fa Mon Sep 17 00:00:00 2001 From: Sergei Poselenov <[EMAIL PROTECTED]> Date: Wed, 29 Oct 2008 13:04:16 +0100 Subject: [PATCH] Added a do_div() wrapper macro, lldiv(). The new macro doesn't modify the dividend and returns the result of division, so it is useful in complex expressions, i.e. "return(a/b)" -> "return(lldiv(a,b))"
