From 68a217169a546c904bb1dc8ac3f1afb36a29020c Mon Sep 17 00:00:00 2001 From: David Greene Date: Fri, 2 Apr 2010 23:17:14 +0000 Subject: Ok, third time's the charm. No changes from last time except the CMake source addition. Apparently the buildbots were wrong about failures. --- 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100249 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Analysis/LoopPass.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/llvm/Analysis/LoopPass.h') diff --git a/include/llvm/Analysis/LoopPass.h b/include/llvm/Analysis/LoopPass.h index 10ff103..6f77d01 100644 --- a/include/llvm/Analysis/LoopPass.h +++ b/include/llvm/Analysis/LoopPass.h @@ -31,6 +31,10 @@ public: explicit LoopPass(intptr_t pid) : Pass(PT_Loop, pid) {} explicit LoopPass(void *pid) : Pass(PT_Loop, pid) {} + /// getPrinterPass - Get a pass to print the function corresponding + /// to a Loop. + Pass *createPrinterPass(raw_ostream &O, const std::string &Banner) const; + // runOnLoop - This method should be implemented by the subclass to perform // whatever action is necessary for the specified Loop. virtual bool runOnLoop(Loop *L, LPPassManager &LPM) = 0; -- cgit v1.1
