These are the release notes for AOMP 19.0-3 AOMP uses AMD developer modifications to the upstream LLVM development trunk. These differences are managed in a branch called the "amd-staging". This branch is found in a mirror of upstream LLVM found at https://github.com/ROCm/llvm-project. The amd-staging branch is constantly changing as it merges the upstream development trunk with its downstream development updates. The AMD modifications are experimental while under review for the upstream trunk. AOMP uses a snapshot of amd-staging at the commit ids and dates listed below. AOMP also includes builds of related ROCm components. We call AOMP a "standalone" build as it does not use or require ROCm with the exception of the kernel module (dkms) and libdrm which are often part of the Linux distribution. AOMP is isolated from any ROCm installations by installing into /usr/lib/aomp and the use of RPATH for runtime libraries.

For AOMP 19.0-3, the last LLVM trunk commit is 40954d7f9bb38b2407fe48a524befc5216f13cccon July 22, 2024. This was the last trunk commit before the trunk forked to LLVM-20. The last amd-only commit is baa883c3ad5d70e1f4da5b6f80f6d06c00b73c3a on July 22, 2024. These commits form a frozen branch now called "aomp-19.0-3". See https://github.com/ROCm/llvm-project/tree/aomp-19.0-3.

The integrated ROCm components for this AOMP release were built with ROCM 6.1.2 sources.

This is the 3rd AOMP release based on upstream LLVM 19 development. Since the LLVM trunk has moved to development of LLVM 20, the next AOMP release will be based on LLVM-20.

Changes since AOMP 19.0-2

  • Support for requires atomic default mem order clause was added.
  • OMPT no longer falls back into synchronous execution mode when profiler is attached.
  • OMPT now supports callbacks for omp_target_associate_ptr and omp_target_disassociate_ptr.
  • Xteam Reduction enabled by default at all opt levels.
  • Some HIP interoperability issues with tracking HIP memory allocations on Mi200 were resolved.
  • Remove deprecated utility offload-arch. This was replaced with amdgpu-arch or nvptx-arch.
