Description

Compared to LLVM 20.0.0, all the 27 failing 'libarcher' tests pass now on LLVM 21.1.0. However, the 'libomp' and 'MLIR' test suites still have the same failures.

Environment

  • LLVM 21.1.1
  • Fedora 42
  • Hardware: "HiFive Premier P550" by SiFive

libomp test failures:

Based on the build log for llvm-21.1.1-2.0.riscv64.fc43 from here.

Failed Tests (7):

libomp :: ompt/misc/control_tool.c
libomp :: ompt/synchronization/barrier/explicit.c
libomp :: ompt/synchronization/critical.c
libomp :: ompt/synchronization/flush.c
libomp :: ompt/synchronization/ordered.c
libomp :: ompt/synchronization/taskgroup.c
libomp :: ompt/synchronization/taskwait.c

MLIR test failures:

(Here is the upstream issue for MLIR: https://github.com/llvm/llvm-project/issues/162655)

Based on the build log for llvm-21.1.1-2.0.riscv64.fc43 from here.

Updates for the MLIR test failures:

Updates for the MLIR test failures: - Filed an `mlir-runner` test suite failure bug: https://github.com/llvm/llvm-project/issues/188073 - Wrote a draft patch based on upstream suggestion: https://github.com/kashyapc/llvm-project/commit/86e20a7c0f04 - We will workaround this upstream problem in Fedora with a couple of patches from here (still testing): https://src.fedoraproject.org/fork/kashyapc/rpms/llvm/commits/filter_out_some_mlir_tests
