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,

Hi all, I am going to build a Pass/es that verify OpenMP code. When we compile an OpenMP program we give the option “-fopenmp” to clang. In this way the LLVM IR code obtained will reflect also the “#pragma” keywords in the code, let’s call it "OpenMP LLVM IR". In my Pass/es before obtaining the OpenMP LLVM IR, I need to do some operation in the LLVM IR, that is the IR code obtained

Hi, Coming back to this, I would greatly appreciate if someone could add this publication (based on TSan) to the list.

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 list, I'm using R 2.8.1 under Windows vista. I have the following problem: First of all I create a string-vector. Then I "convert" these strings into variables and assign a vector of numeric values. So far everything's fine. Now I want to do nearly the same again: I create another string-vector and I want to assign the variance. So I have to loop over the first

Hi Tobi Thanks a lot for your detailed update on the status of OpenMP in LLVM. It looks like there is no "official" support of OpenMP in LLVM 3.x at least. In your descriptive list, I can see that [a] is an optional patch or available in GCC, [b] & [c] are available as optional runtimes (which have to be carefully bundled). [d] anyway is little different from OpenMP (can exist

Hi, I was wondering if there is a way with llvm-lit and FileCheck to identify if a specific test should run or not based on the processor architecture. For example, I have a test that can run only in an Intel KNL, so if I run the tests in a Sandybridge I want to ignore that test. Any idea? Thanks!

Hi, I am trying to make my pass compiling inside the LLVM tree or outside. It works when I include my pass inside the tools folder, however when I try to compile it outside the LLVM tree I get the following error: "add_library cannot create target "LLVMTarget" because an imported target with the same name already exists.” It happens when I’ve already compiled and installed my

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

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,

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 I wanted to know the status of OpenMP (or in general auto parallelization) support in LLVM. I read some threads discussing about possible effort in that direction in 3.1 onwards, but did not see any further discussion on that. If someone in the list knows the updated info or can point me to any useful info, that would be useful. Thanks Regards Prakash Raghavendra -------------- next part
