similar to: llvm-lit and FileCheck: How to ignore unsupported architecture for a specific test

Hi all, quite a few tests use the pattern "2>&1 | FileCheck %s". AFAIK how stdout and stderr are merged into a single character stream is undefined and depends e.g. on whether stdout is buffered. I think we are often saved by the fact that standard output is written only at the end of the program and stderr is unbuffered, i.e. always written before stdout. A lot of tests disable

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

All the density estimators I've found in R seem to force the ends to go to zero. What can we do if we don't believe that, e.g., with something that might be a uniform distribution or a truncated normal with only observations above mu+sigma observed? The closest I could come to this was to artificially extend the numbers beyond the range, thereby forcing the density estimator

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

So I manage to get clang's colored output through ninja simply by force (CMAKE_CXX_FLAGS=-fcolor-diagnostics), which isn't ideal (if I were to pipe ninja's output to a file it'd still have color escapes, etc) but it works. But I haven't found a similar solution for FileCheck & I'm wondering has anyone already solved this problem for themselves - if so, how? if not,

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 Frank, I recommend trying trunk LLVM. AVX-512 development has been very active recently. -Hal ----- Original Message ----- > From: "Frank Winter via llvm-dev" <llvm-dev at lists.llvm.org> > To: "LLVM Dev" <llvm-dev at lists.llvm.org> > Sent: Wednesday, June 29, 2016 2:41:39 PM > Subject: [llvm-dev] avx512 JIT backend generates wrong code on <4

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! When compiling the attached module with the JIT engine on an Intel KNL I see wrong code getting emitted. I attach a complete exploit program which shows the bug in LLVM 3.8. It loads and JIT compiles the module and prints the assembler. I stumbled on this since the result of an actual calculation was wrong. So, it's not only the text version of the assembler also the machine

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 Hal! Thanks, but unfortunately it didn't help. The exact same assembler instructions are generated for both 3.8 (yesterday) and trunk (from today). So, this really looks like a bug.
