similar to: [LLVMdev] Problem with generating Machine function analysis pass

Hi, Anybody has an opinion would it be good thing to add support for llvm- gcc to be able to be built with existing llvm installation? Right now building works with llvm installation also, but only if llvm libs and includes are installed under the same prefix, even though this seems to be unintended functionality. So after support for building llvm-gcc without llvm sources it would be

Good morning! After updating and recompiling my copy of the LLVM trunk I noticed that the line "_passManager.add(llvm::createTailDuplicationPass());" in my code fails with the following assertion: Assertion failed: NormalCtor && "Cannot call createPass on PassInfo without default ctor!", file D:\Workspace\llvmtrunk\include\llvm/PassSupport.h, line 111 This behavior

I'm trying to access the MachineFunctionInfo structure from a pre-ISel pass. In order to do this I have to get access to the MachineFunction and then call getInfo(). Currently in my pass I request it via: void AMDILBarrierDetect::getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<MachineFunctionAnalysis>(); FunctionPass::getAnalysisUsage(AU); } However, I am getting an

While trying to add a pass to the ARM back end I'm getting quite a lot of this assertion failure: Pass.cpp:255: llvm::Pass* llvm::PassInfo::createPass() const: Assertion `NormalCtor && "Cannot call createPass on PassInfo without default ctor!"' failed. A simple way to get it is to add two lines to ARMTargetMachine.cpp: #include "llvm/Transforms/Scalar.h" and

Hi, I have trouble making my ProfileInfo-Analysis available in the backend, I have changed llc so it loads the ProfileInfo if requested, the PassManger gives this output: > Target Data Layout > Create Garbage Collector Module Metadata > Basic Alias Analysis (default AA impl) > DWARF Information Writer > No Profile Information > Module Information > ModulePass

Hi, I've been hitting my head to wall two days now. This is practically my first contact with InstrInfo.td files. Is there any tutorial how to make this kind of stuff? Or should I just keep on studying Sparc and other backends? So I added new intrinsic to llvm/include/llvm/TCEInstrinsics.td: def int_tce_customop : Intrinsic<[llvm_void_ty, llvm_ptr_ty, llvm_vararg_ty], [],

However my impression was that Mikael's original patch would break building against

Hi Michael, hi Duncan, yesterday I stumbled over something that might be related. At least I could also just be doing some initialization wrong or something in this direction... In my case, I hit a segfault in PassInfo::isAnalysisGroup() after PassManager.add(myModulePass) is called. My setup seems fairly simple, the attached code should reproduce the error. Compile with g++ test.cpp

Your constructor is not calling initializeTestMPPass(), and you're using RegisterPass which I think was deprecated in favor of INITIALIZE_PASS. You can look at, for example, lib/Transforms/Scalar/IndVarSimplify.cpp for examples of how to initialize, e.g. having "INITIALIZE_PASS_DEPENDENCY(LoopInfo)" sandwiched between BEGIN and END. Note that you'll want a forward declaration of

Dear everyone, I want to traverse call graph, but I have some trouble . In my pass MyPass which need to traverse call graph, I firstly added the CallGraph analysis to the pass requirements by *AU.addRequired<CallGraph>();* My pass MyPass then will be added to a pass manager by *manager.add(new MyPass());* and then I want to traverse the call graph such as: CallGraph CG =

If you're looking to see if your program only accesses in-bounds memory, SAFECode and Address Sanitizer may be able to do this for you already. If

---------- Forwarded message ---------- From: Qingan Li <ww345ww at gmail.com> Date: 2011/5/30 Subject: To: llvmdev at cs.uiuc.edu Hi, I wrote an analysis pass, myPass, inherited from both ModulePass and ProfileInfo, and this pass requires the CallGraph, i.e., * class myPass : public ModulePass, public ProfileInfo { ...};* * void myPass::getAnalysisUsage(AnalysisUsage &AU) const

I recall having a similar problem while coding my own special-purpose "opt". My guess: try adding the following lines before your pass is inserted into the PassManager: PassRegistry &Registry = *PassRegistry::getPassRegistry(); initializeIPA(Registry); You might require other library initializations. Have a look at the "opt" source code. On 02/12/13 10:36,

Hi, Would it be possible to set tbgen to be installed with llvm? For our project http://llvm.org/ProjectsWithLLVM/#tta-tce it would be very helpful, because our tools generate compiler backend plugins in the fly for each customized processor and plugin generation needs tbgen for handling td files. Because of tbgen not beeing distributed, our users cannot use llvm from their favorite

Hi, I'm trying to write custom pass. However opt started crashed in opt.cpp. After debugging it looks like PassInf->NormalCtor points to unmapped memory (rest of struct contains correct data about my pass) - it pointed high in user memory (0x756e672e006e6f69). It happens only when I tried to install debug version of llvm system-wide (I've check that it wasn't caused by stale .a
