Description of problem: LLVM/Clang requires a manual build to enable OpenMP offload capabilities for NVDIA GPUs. With LLVM 12 the build needs up to two flags to include offload capabilities: 1) if `LLVM_ENABLE_RUNTIMES` is not set to `all` it should include `openmp` 2) `LIBOMPTARGET_BUILD_NVPTX_BCLIB` should be set to `TRUE` Version-Release number of selected component (if applicable): LLVM/Clang before release 12. How reproducible: On a system with a NVIDIA GPU and cuda installed and locatable on the library path, compile OpenMP offload code and check if it is run on the device: ``` // a.c int main() { #pragma omp target { } } ``` clang -fopenmp -fopenmp-targets=nvptx64 a.c -o a.out ./a.out Actual results: 0 return value Expected results: Error because execution on the GPU didn't happen but was mandatory.
To confirm, it landed in llvm/clang 12 ?
Yes, LLVM 12 should have all the required patches.
This message is a reminder that Fedora 33 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '33'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 33 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 33 changed to end-of-life (EOL) status on 2021-11-30. Fedora 33 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
