similar to: CloneFunction during LTO leads to seg fault?

Hi Medhi, Thanks for you reply. Here is the full output of -print-after-all [1] and just the module itself after my pass[2]. I've looked over the IR, but I can't see anything obviously wrong. I'm not sure what you meant by: > You may want to try to add it at the end of the pipeline My pass is the last one added inside populateLTOPassManager. Should I add it to the

The core of the issue is that CloneFunction (with ModuleLevelChanges=true) on a function that has had other functions inlined into it generates orphan debug info metadata nodes. Then when this module is emitted, DwarfDebug

In general I use DebugInfoFinder and clear out Metadata if GV in null or GV->isDeclaration(). If there is any interest, I can post that patch...

Hi, I want to duplicate a function and transfer it from one module to another. I found "CloneFunction()" but it needs an "vMap". I found that "vMap" is used to map the original values to the new values. So, hypothetically, if the original function uses a global variable from the previous module and I want that use in the new function to be mapped to a global variable

I'm confused by your code. StaticInitializer seems to exist so you can create InitializeEverything, which doesn't get used. Do I need to do something along the lines of: static void registerPollyPasses(const llvm::PassManagerBuilder &Builder, llvm::PassManagerBase &PM) { PM.add(llvm::createPromoteMemoryToRegisterPass());

Hi, I am trying to use the CloneFunction from llvm/Transforms/Utils/Cloning.h and I don't understand how the ValueToValueMapTy argument should be initialized. For instance, let say I want to clone this function (to add an argument): define void @function(i32 %i) #0 { entry: %i.addr = alloca i32, align 4 store i32 %i, i32* %i.addr, align 4 ret void } to another function which should,

Andy and I briefly discussed this the other day, we have not yet got chance to list a detailed pass order for the pre- and post- IPO scalar optimizations. This is wish-list in our mind: pre-IPO: based on the ordering he propose, get rid of the inlining (or just inline tiny func), get rid of all loop xforms... post-IPO: get rid of inlining, or maybe we still need it, only

I'm writing a Pass that I would like to remain loadable by opt. The pass also requires DominatorTree(for PromoteMemToReg). Looking for examples the only way I found to require a dependecny is by doing something like this: char Hello::ID = 0; namespace llvm { void initializeHelloPass(llvm::PassRegistry&); } INITIALIZE_PASS_BEGIN(Hello, "hello", "Hello

Hi, we have two modules, one that we basically use as a library in which we store a lot of simple function calls, the other is small program generated at run-time. Whenever a function call for to one of the builtin functions is being called we use CloneFunction to clone the instruction from the library module and insert it in the generated module. The problem is for example when we have

I was just going to say: With well-formed debug info it should create a deep copy up until the DISubprogram, but no further. But because the DISubprogram linked to the Function is missing the special handling of the DISubprogram (that would prohibit cloning the DICompileUnit is side-stepped). But then I remembered the discussion we had in

I seem to recall havbing asked this before but I can't find it by searching. What's the right way to clone a Function? I need to save off the text at a certain point and spit it out later, after other optimizations have run. But I need to spit out the original text, not the optimized version. What would be the most effective way to do this?

I just wrote an IR Verifier check that catches the following situation: ; RUN: not llvm-as %s -disable-output 2>&1 | FileCheck %s define void @f1() !dbg !4 { unreachable } ; CHECK: DISubprogram attached to more than one function define void @f2() !dbg !4 { unreachable } !llvm.dbg.cu = !{!1} !1 = distinct !DICompileUnit(language: DW_LANG_C99, file: !2) !2

Hi, I wanted to backup a Function before it is optimized. The Function class disallows assignment operations as it comments: Function(const Function&); // DO NOT IMPLEMENT void operator=(const Function&); // DO NOT IMPLEMENT Is there a way to construct a copy from an existing Function?
