llvm build failure for openmp #59537

jeffcbecker · 2022-12-15T19:27:39Z

On x86/Linux, did the following

$ cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD=X86 -DLLVM_ENABLE_PROJECTS=clang -DLLVM_ENABLE_RUNTIMES=openmp ../llvm
$ make
...

Build gets to 98% complete, and has the following error

Consolidate compiler generated dependencies of target omptarget

What version is your compiler? The include/c++/4.8.5 seems a little suspect, it might be picking up the wrong compiler when we do the second build for the "runtimes" option. Sometimes the LLVM build will pick up the system's default GCC instead of the one that's expected. I've used -DGCC_INSTALL_PREFIX= in the past to get around that, it's worth a shot.

I tried again with GCC 10.3 and got:

Was this a clean build, that is with previous installations and the build directory deleted? Sometimes CMake will cache problematic variables, or files from the old installation will be used when we want them to be rebuilt.

jeffcbecker · 2022-12-15T20:23:10Z

no - I'll start clean, tx

jeffcbecker · 2022-12-15T22:07:47Z

Did a clean cmake followed by make -j8. Errors follow. If you'd prefer, I can do a single threaded make. Tx

I tried locally with GCC 10 but cannot reproduce the error you observed. It'll be more helpful if you can attach the full log, including CMake configure and make -v.

jeffcbecker · 2022-12-18T01:12:13Z

OK. Did git pull on llvm-project followed by cmake and make. Outputs from both commands attached.

How did you make clang choose GCC 10 in the second build pass for OpenMP? I didn't see you use GCC_INSTALL_PREFIX. I'm asking because I think clang by default will use system GCC instead of the one from modules.

jeffcbecker · 2022-12-19T19:13:12Z

I didn't realize I needed to do anything. Where do I specify GCC_INSTALL_PREFIX?

I mentioned earlier to pass -DGCC_INTALL_PREFIX=<path> to the CMake invocation. Start with a fresh build too. The prefix should be the directory where you can get ./bin/gcc

shiltian · 2022-12-19T19:16:07Z

Hmm, based on your initial description, it looks like you were using the system GCC 4.8.5. Later it became GCC 10.3.

jeffcbecker · 2022-12-19T19:42:55Z

correct - I forgot to load the module on the initial issue

jhuber6 · 2022-12-19T19:44:54Z

The module system usually causes a lot of problems when certain tools prefer to look at the system's binaries rather than whatever PATH or LD_LIBRRY_PATH tells them. -DGCC_INSTALL_PREFIX usually fixed my problems when building things on clusters with very old system installations of gcc so let me know if it's still broken after a clean build with that set to the path in the module.

shiltian · 2022-12-19T19:47:01Z

Yeah, that's the tricky part. AFAIK, module load gcc cannot make clang to use it by default. Some manual efforts have to be done to force clang to use the GCC loaded by module. GCC_INSTALL_PREFIX is usually the best way to handle that. Another way is to use clang config file, which also requires some extra arguments when building clang. Since you don't have both, I'm not sure how clang can pick up the GCC 10.3 loaded by module. My wild guess is your module did something and that causes the compile error you observed.

Success! My ultimate goal of this was to build OpenMP target offload for NVIDIA and AMD GPU's. Although I did not specify nvptx or amdgpu as LLVM_TARGETS_TO_BUILD, it looks like those might have been built (runtime.txt attached with make -j8 output). Do I need to do anything else? Thanks!

Glad to hear it. All targets are built by default unless specified otherwise. Right now we should be able to build both the AMD and NVIDIA offloading support even without a valid ROCm / CUDA installation. Here's a useful program that returns 0 if offloading was successful.

// clang test.c -fopenmp --offload-arch=<arch>
#include <omp.h>

int main() {
  int isDevice = 0;
#pragma omp target map(from : isDevice)
  { isDevice = omp_is_initial_device(); }
  return isDevice;
}

Let me know if this works for you.

jeffcbecker · 2022-12-19T22:07:17Z

I asked because my cmake specified
-DLLVM_TARGETS_TO_BUILD=X86

However the make output contains lines like:
[ 47%] Extracting LLVM bitcode libomptarget-amdgpu-gfx940.bc
[ 47%] Building CXX object openmp/libomptarget/plugins/cuda/CMakeFiles/omptarget.rtl.cuda.dir/src/rtl.cpp.o

...
[ 53%] Embedding LLVM offloading binary in devicertl-amdgpu-gfx940.o

jeffcbecker · 2022-12-19T22:22:01Z

also, my cmake had:
-DLLVM_ENABLE_PROJECTS=clang

and I was wondering if I needed to add : openmp

jhuber6 · 2022-12-19T23:02:54Z

-DLLVM_ENABLE_RUNTIMES=openmp is a replacement for -DLLVM_ENABLE_PROJECTS=openmp. And yes, since you only built X86 you need to set it to X86;NVPTX;AMDGPU to be able to offload.

jeffcbecker · 2022-12-19T23:25:24Z

Not sure what's wrong but...

-DLLVM_TARGETS_TO_BUILD="X86;NVPTX"

jeffcbecker · 2022-12-20T00:30:06Z

got both targets to build - thanks

jeffcbecker · 2022-12-21T00:56:02Z

@jhuber6 , I tried your test.c program above, and added a print statement to print isDevice before returning. I compiled it with:

$ clang test.c -fopenmp -fopenmp-targets=nvptx64

$ ./a.out
isDevice is 1

You had indicated that it should return 0, so it seems like offloading is not working. Please advise

Do you have a functioning install of CUDA or ROCm with a compatible GPU on the system? One of the following should at least indicate the presence of a GPU for starters, rocm-smi, nvidia-smi, llvm-omp-device-info.

shiltian · 2022-12-21T01:20:03Z

@jeffcbecker I don't think the discussion is about the ticket anymore. I'll close it. In addition, for those questions of using OpenMP target offloading, https://discourse.llvm.org/c/runtimes/openmp/ is a better place. GitHub issue is more for bug report.

ms178 · 2022-12-22T21:35:05Z

@jhuber6 I still see

ld.lld: error: version script assignment of 'VERSION' to symbol 'ompt_start_tool' failed: symbol not defined
ld.lld: error: version script assignment of 'VERSION' to symbol 'ompt_libomp_connect' failed: symbol not defined

as of 69243cd. I don't get these when using Mold-git as my linker.

PKGBUILD.txt

jhuber6 · 2022-12-22T21:37:45Z

That's caused by lld recently changing the default to error on undefined symbols in version scripts. Someone needs to either define dummy versions of those symbols or adjust the version script. Can you open a new issue?

ms178 · 2022-12-22T21:38:47Z

Sure, I'll open a new issue. Filed it here: #59660
