similar to: Problem using Boost Filesystem with Clang

Hi all, I'm a new user to LLVM. Not really sure if this is the correct place to post, since there isn't really any other forums around. Anyway, the issue I'm encountering is that, I was trying out the first tutorial (http://llvm.org/docs/tutorial/JITTutorial1.html). I attempted to do this in another folder that was copied from llvm/projects/sample. I created a new folder called

To get Tutorial 1 to compile, I had to cast cout as a raw_osstream, as in: PM.add(createPrintModulePass(&llvm::cout)); ----> PM.add(createPrintModulePass((raw_ostream*)&llvm::cout)); I was getting the following error: $ c++ -g tut1.cpp `llvm-config --cxxflags --ldflags --libs core` -o tut1 tut1.cpp: In function ‘int main(int, char**)’: tut1.cpp:19: error: cannot convert

Thank you for your reply Anton. I'm sorry it's taken a while to get back to you.

Hi, I am not sure how widespread this problem is, but definitely occurs for me on 64 bit Win 7 with a 64 bit R. I think I have isolated the issue (to a certain extent) in the attached Test.cpp file. Basically, I think linking with boost serialization is causing the plugin to fail. If I compile Test.cpp with line 43 (Dummy* Read() ...) commented out, I get the expected output in R: >

Thanks John. I guess I will use a ModulePass, so when I am implementing the “runOnModule” function, do I have to loop through all the functions, for each functions all the BasicBlocks and for each BasicBlock all the instructions or given the Module I have to call the CallGraph directly? Is there an example out there? I can’t find anything. Thanks. Simone > On Feb 24, 2015, at 13:29, John

Hi all, I would like to create a Pass that given an IR instruction walks starting from that instruction up to the main function to identify all the functions call that have been made to call that instruction. Is it possible? What kind of Pass should I create? Thanks Best, Simone Simone Atzeni simone.at at gmail.com +1 (801) 696-8373

Hi experts, My customer issued debugocfs to check for file_size and extent info but values such as file_size, alloc_size, next_free_ext were 0.

I ran into a similar problem a while ago; see https://reviews.llvm.org/D30107 and https://reviews.llvm.org/D33515 .  You get the unusual stack trace because it's trying to call a destructor in shared library which was already unloaded. I thought we had fixed that, but maybe not?  Looking again, it looks like the patch got reverted and I didn't notice. -Eli On 5/14/2018 10:18 PM,

Because what is happening is that if function “atoi” gets cloned I don’t have a definition of “atoi_parallel” therefore I get undefined references when linking. I just want to clone and instrument functions implemented in modules of my program. > On Nov 19, 2016, at 13:54, Mehdi Amini <mehdi.amini at apple.com> wrote: > > >> On Nov 19, 2016, at 12:44 PM, Simone Atzeni

Hi, I am trying to compile LLVM for AARCH (VMA=42), here my cmake command: cmake -G "Ninja" -D SANITIZER_AARCH64_VMA=42 .. But I get the following warning: ------------------------------------------------------------------------------------------ CMake Warning: Manually-specified variables were not used by the project: SANITIZER_AARCH64_VMA

Thanks Mehdi. My pass clones the functions within a module in order to have the original function and an exact copy of the same function but with a different name, i.e. sum() and sum_parallel(). After my pass I will run ThreadSanitizer instrumentation pass only on the new copy of the functions, i.e. only the “_parallel” functions will be instrumented by tsan. In some programs that I am

It's working with trunk though. Do you think the patch will end up in 6.0.1? Thanks.

Hi, as in the subject, is it possible to call on of the analysis pass present in the LLVM (lib/ folder) within a tool pass (tools/ folder)? Thanks. Best, Simone

Hi all, I was porting my pass from LLVM 4.0 to 6.0 and I am getting a segmentation fault. I was able to obtain only the info below from GDB. I tried to debug with some printf and the runOnFunction runs correctly. Any idea/suggestion about what is going on? The source code of the pass is here: https://github.com/PRUNERS/sword/blob/master/lib/Sword.cpp Any help is much appreciated, Thanks!

Hi, supposing I have a function “foo” like the following: int foo(int a, int b) { ... ... } I want to insert int the LLVM IR a call instructions to a function “bar” that requires the same parameters of foo. So my function foo will become: int foo(int a, int b) { bar(a,b); … ... } I am using the following code: bool ThreadSanitizer::runOnFunction(Function &F) {
