From 3e58d9bb320f247740672aeb3129c4755d02b599 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 13 Oct 2003 05:33:01 +0000 Subject: * Remove extraneous #includes * Fix a nasty initializer ordering bug. Any only-CFG passes which registered themselves before the CFGOnlyAnalysis vector initialized got forgotten and thus got invalidated and recomputed. In particular, in my compiled version of gccas, the Loop information pass was being recomputed unnecessarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9074 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/VMCore/Pass.cpp | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) (limited to 'lib/VMCore/Pass.cpp') diff --git a/lib/VMCore/Pass.cpp b/lib/VMCore/Pass.cpp index 0d25afc769..c9b97c879a 100644 --- a/lib/VMCore/Pass.cpp +++ b/lib/VMCore/Pass.cpp @@ -1,4 +1,4 @@ -//===- Pass.cpp - LLVM Pass Infrastructure Impementation ------------------===// +//===- Pass.cpp - LLVM Pass Infrastructure Implementation -----------------===// // // This file implements the LLVM Pass infrastructure.
