From f7f0d6c7560a8f71707e7852a512469147aa9f84 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Thu, 11 Aug 2011 20:53:28 +0200 Subject: cppcheck complains about some possible speed improvements which could be done on the mirco-optimazation level, so lets fix them: (performance) Possible inefficient checking for emptiness. (performance) Prefer prefix ++/-- operators for non-primitive types. --- cmdline/apt-cache.cc | 104 +++++++++++++++++++++++++-------------------------- 1 file changed, 52 insertions(+), 52 deletions(-) (limited to 'cmdline/apt-cache.cc') diff --git a/cmdline/apt-cache.cc b/cmdline/apt-cache.cc index 232bb93ec..db5475227 100644 --- a/cmdline/apt-cache.cc +++ b/cmdline/apt-cache.cc @@ -141,7 +141,7 @@ bool ShowUnMet(pkgCache::VerIterator const &V, bool const &Important) if (Start == End) break;
