similar to: [LLVMdev] insert printf into IR

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

Hello, I am trying to do some simulation using the rmetasim package and I've run to this problem. --beginning of error msg-- Error in "[<-"(`*tmp*`, slice[l, ], slice[l, ], value = c(0.200000002980232, : number of items to replace is not a multiple of replacement length --end of error msg-- Here is the script I used. --script starts here-- ## load 'rmetasim'

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!

Hi Everyone, I am trying to insert an exit function into my IR. However, I thought I can get access to exit by using Module.getOrInsertFunction or Module.getFunction. However, I am getting a null value returned. I have searched through the llvmdev archives but not found any thing that addresses this question. Any help will be greatly appreciated. Thanks.

Hi, I am trying to use some LLVM API in my C++ code, and I end up getting linker errors. I am working on Apple MacOSX Lion. Using g++ for the compile.

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, I created a global char array, char buffer[1024]. I want to call a function to append the string information to the buffer repeatedly. For example, I need to implement the following code, where length, a, b, c, are global variables. int length = 0; length += sprintf(buffer+length, "str%d", a); length += sprintf(buffer+length, "str%c", b); length += sprintf(buffer+length,

Probably your g++ compiles x86_64 binary by default, but i686 dylib is supplied? Try: g++ -m32 e.cpp /Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/libexec/gcc/i686-apple-darwin10/4.2.1/libllvmgcc.dylib - D. 2012/1/22 Arpan Sen <arpansen at gmail.com>: > Hi, > > I am trying to use some LLVM API in my C++ code, and I end up getting linker > errors.

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 it works.

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

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

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
