...foo()` supposed to call `foo_parallel()` after? I insert some more code that basically check if the function is called within an OpenMP parallel region or not, if so the function foo will call foo_parallel.

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

...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, Simone Atzeni via llvm-dev wrote: > This is the correct path to the pass: > https://github.com/PRUNERS/sword/blob/master/lib/Transforms/Instrumentation/InstrumentParallel.cpp > > On Mon, May 14, 2018 at 10:06 PM, Simone Atzeni <simone.at at gmail.com > <mailto:simone.at at gmail.com>&gt...

...or there could be situations of functions with that linkage but that have the body implemented in the same module. Does it make sense now? Thanks.

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

...ally, you need to start searching from this node as well as the main() node (as a program can call out to external code which then calls back into the program; think of qsort() as an example).

...very new in LLVM and I am trying to understand how to use it in my project. I would like to write a Pass (?) that analyzes the loops in a program and says if the loop has a data dependence and what kind of data dependence. Do you guys have any suggestion how do to it? Thanks. Best Regards, Simone Atzeni

Hi, when I run cmake I get the following warning: --------------------------------------------------------------------------------------- CMake Warning at cmake/modules/HandleLLVMStdlib.cmake:24 (message): Can't specify libc++ with '-stdlib=' Call Stack (most recent call first): cmake/config-ix.cmake:15 (include) CMakeLists.txt:580 (include)

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, not sure if this is the right place, but I am experiencing a problem using clang++ (3.9.1) with Boost Filesystem. I have this simple program: ------------------------------------------------------------------------ #include <iostream> #include <boost/filesystem.hpp> using namespace boost::filesystem; int main(int argc, char* argv[]) { if (argc < 2) { std::cout

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, I am writing a plugin to get information about the OpenMP constructs from the AST. I am basically writing a “RecursiveASTVisitor” and I am trying to find the OpenMP statement and get information like filename and line of code. When I am visiting recursively each statement I have my own switch on the “StmtClass” and for now I am focusing on “OMPParallelForDirectiveClass”. In my understanding,
