From 8f32cb9fce4102a682cc5fa419ba23509161b174 Mon Sep 17 00:00:00 2001 From: David Greene Date: Fri, 2 Apr 2010 18:46:26 +0000 Subject: Let's try this again. Re-apply 100143 including an apparent missing include. For some reason the buildbot choked on this while my builds did not. It's probably due to a difference in system headers. --- Add some switches helpful for debugging: -print-before= Dump IR before running pass . -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass. These are helpful when tracking down a miscompilation. It is easy to get IR dumps and do diffs on them, etc. To make this work well, add a new getPrinterPass API to Pass so that each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass suitable for dumping out the kind of object the Pass works on. llvm-svn: 100204 --- llvm/lib/CodeGen/MachineFunctionPass.cpp | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'llvm/lib/CodeGen/MachineFunctionPass.cpp') diff --git a/llvm/lib/CodeGen/MachineFunctionPass.cpp b/llvm/lib/CodeGen/MachineFunctionPass.cpp index 2f8d4c9e7aa..e5a491270a8 100644 --- a/llvm/lib/CodeGen/MachineFunctionPass.cpp +++ b/llvm/lib/CodeGen/MachineFunctionPass.cpp @@ -15,8 +15,14 @@ #include "llvm/Analysis/AliasAnalysis.h" #include "llvm/CodeGen/MachineFunctionAnalysis.h" #include "llvm/CodeGen/MachineFunctionPass.h" +#include "llvm/CodeGen/Passes.h" using namespace llvm; +Pass *MachineFunctionPass::createPrinterPass(raw_ostream &O, + const std::string &Banner) const { + return createMachineFunctionPrinterPass(O, Banner); +} + bool MachineFunctionPass::runOnFunction(Function &F) { // Do not codegen any 'available_externally' functions at all, they have // definitions outside the translation unit. -- cgit v1.2.3
