From 8a261e44f71a433b7d9af373c3e3dfa6fea67146 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Thu, 8 Oct 2009 17:00:02 +0000 Subject: Add a form of addPreserved which takes a string argument, to allow passes to declare that they preserve other passes without needing to pull in additional header file or library dependencies. Convert MachineFunctionPass and CodeGenLICM to make use of this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83555 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineFunctionPass.cpp | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) (limited to 'lib/CodeGen/MachineFunctionPass.cpp') diff --git a/lib/CodeGen/MachineFunctionPass.cpp b/lib/CodeGen/MachineFunctionPass.cpp index fd8a210c4f..2f8d4c9e7a 100644 --- a/lib/CodeGen/MachineFunctionPass.cpp +++ b/lib/CodeGen/MachineFunctionPass.cpp @@ -11,11 +11,8 @@ // //===----------------------------------------------------------------------===// +#include "llvm/Function.h" #include "llvm/Analysis/AliasAnalysis.h" -#include "llvm/Analysis/ScalarEvolution.h" -#include "llvm/Analysis/IVUsers.h" -#include "llvm/Analysis/LiveValues.h" -#include "llvm/Analysis/MemoryDependenceAnalysis.h" #include "llvm/CodeGen/MachineFunctionAnalysis.h" #include "llvm/CodeGen/MachineFunctionPass.h" using namespace llvm; @@ -36,15 +33,18 @@ void MachineFunctionPass::getAnalysisUsage(AnalysisUsage &AU) const { // MachineFunctionPass preserves all LLVM IR passes, but there's no // high-level way to express this.
