From 60f8a63e2502d57e879bf52a4a48505b74fa9716 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Tue, 17 Feb 2009 20:49:49 +0000 Subject: Add a method to ScalarEvolution for telling it when a loop has been modified in a way that may effect the trip count calculation. Change IndVars to use this method when it rewrites pointer or floating-point induction variables instead of using a doInitialization method to sneak these changes in before ScalarEvolution has a chance to see the loop. This eliminates the need for LoopPass to depend on ScalarEvolution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64810 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/LoopPass.cpp | 3 --- 1 file changed, 3 deletions(-) (limited to 'lib/Analysis/LoopPass.cpp') diff --git a/lib/Analysis/LoopPass.cpp b/lib/Analysis/LoopPass.cpp index da9ac27..c45c2ef 100644 --- a/lib/Analysis/LoopPass.cpp +++ b/lib/Analysis/LoopPass.cpp @@ -14,7 +14,6 @@ //===----------------------------------------------------------------------===// #include "llvm/Analysis/LoopPass.h" -#include "llvm/Analysis/ScalarEvolution.h" using namespace llvm; //===----------------------------------------------------------------------===// @@ -173,8 +172,6 @@ void LPPassManager::getAnalysisUsage(AnalysisUsage &Info) const { // LPPassManager needs LoopInfo.
