similar to: [LLVMdev] inserting exit function into IR

Hi George, Could you be a more specific about what you are trying to do, how you are trying to do it, and what is failing. A couple of relevant snippets of code would do wonders in helping you.

Hi Joshua, I have a function foo and I want to insert exit(0) at the end of foo. The problem is M.getFunction returns null, which is understandable. I am not sure what to do. Below is the code snippet. void foo(int argc, char* argv[]) { printf("hello world\n"); exit(0); //***I want to insert this exit } My llvm code snippet is vector<const Type *> params =

I did M.getOrInsertFunction and called the exit function with . IRBuilder<> builder = IRBuilder<>(...); Value *one = ConstantInt::get(Type::getInt32Ty(M.getContext()),1); builder.CreateCall(exitF,one,"tmp4"); "Instruction has a name, but provides a void value! %tmp4 = call void @exit(i32 1) Broken module found, compilation aborted! " On Thu, Mar 31,

Hi Everyone, I am trying to construct the print statement : printf("value:%d\n", value); This is my llvm code. It is seg faulting at builder.CreateGlobalStringPtr(str,""). Thanks. George vector<const Type *> params; params.push_back(Type::getInt8PtrTy(M.getContext())); FunctionType *fType = FunctionType::get(Type::getInt32Ty(M.getContext()), params, true); Constant

Thank you very much guys, I really appreciate your help.

Hi All, I am trying to insert printf ("%d", v), where v is an integer param, into the IR. I am doing something wrong because I keep getting segfaults. Below is my code. Thanks. vector<const Type *> params; params.push_back(Type::getInt8PtrTy(M.getContext())); params.push_back(Type::getInt32Ty(M.getContext())); FunctionType *fType =

Hmmm, but it has a getDirectory function. -G On Thu, Oct 4, 2012 at 3:50 PM, Eric Christopher <echristo at gmail.com> wrote: > That's because instructions have a location associated with them, not > a compile unit. > > -eric > > On Thu, Oct 4, 2012 at 12:46 PM, George Baah <georgebaah at gmail.com> wrote: > > I used DILocation instead of DICompileUnit and

Here is the code. I am running on llvm 3.1 on Lion (Mac 10.7.4) *string getFileDirectory*(*const* Instruction &I){ MDNode *MD = I.getMetadata("dbg"); DICompileUnit compileUnit(MD); return compileUnit.getDirectory().str(); } George On Wed, Oct 3, 2012 at 12:40 PM, Eric Christopher <echristo at gmail.com>wrote: > Without knowing the code that you've written

You should probably think of the DIFooBar constructors like reinterpret-casts, not "go find the thing I actually want" functions. If you hand DICompileUnit() a node that is not a compile-unit metadata node, it's not going to tell you that you goofed. If you _did_ have a CU metadata node, then DICompileUnit's getDirectory() would work just fine. But you don't. --paulr

I used DILocation instead of DICompileUnit and it works. Hmmm, interesting. George On Thu, Oct 4, 2012 at 1:33 AM, George Baah <georgebaah at gmail.com> wrote: > Here is the code.

Yeah, It looks like I am doing exactly what's in Dwarf*.cpp files, yet I am getting blanks.

I mean an llvm Pass that transforms switch statements into if statements. For example, if I have code with switch statements then running the pass will convert all switches to ifs in the bytecode.

Hi Folks, Is a java frontend still being developed for llvm? George -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20120726/95b28fc7/attachment.html>

I have a pointer to a function that I need to invoke without going through llvm::Module::getOrInsertFunction. This example does not work: static int add(int x, int y); llvm::Value *one, *two; llvm::Constant* addfn = llvm::ConstantInt::get(JB->getIntPtrTy(DataLayout), (intptr_t)add); llvm::Type* args[] = { Int32Ty, Int32Ty }; llvm::FunctionType* ftype = llvm::FunctionType::get(Int32Ty,

Hi Guys, I am using the Postdom pass and I would like to get the root of the tree. However, everytime I try to get the root, I get a segfault. I don't know why the environment can't find DominatorTreeBase. Below is the code that generates the Segfault. In my .h file I include Dominators.h PDT.getRootNode(); //PDT is a reference to a PostDominatorTree dyld: lazy symbol binding
