AOMP Release 16.0-2

These are the release notes for AOMP 16.0-2. This release uses modifications to the LLVM development trunk called the "amd-stg-open" branch. This is found at https://github.com/RadeonOpenCompute/llvm-project. The amd-stg-open branch is constantly changing as AMD merges upstream development trunk with its internal open development efforts. Some AMD modifications are experimental and/or under review for the LLVM upstream mono-repo. The AOMP release is a snapshot of amd-stg-open and supporting repositories to build various components.

For AOMP 16.0-2, the last trunk commit is 0ccff030f3b4145bd658e362a63db9aae2942bee on Oct 15 2022. This is the 3rd AOMP release for LLVM 16 development. The last amd-only commit is 863a830a66c8bdb5371e56030961449df24d5c48 on Nov 2, 2022. This forms a frozen branch now called "aomp-16.0-2". See https://github.com/RadeonOpenCompute/llvm-project/tree/aomp-16.0-2. Currently, the amd-only content differs from the trunk by 62480 lines in 459 files.

AOMP is a "standalone" build of all necessary ROCm components with the exception of the kernel module and libdrm. The non llvm-project components for this release were built with ROCM 5.3.x sources.

These are the changes from 16.0-1 to 16.0-2 include:

• Dropped support for Ubuntu 18.0-4.
• Fix for early USM failure - openfoam does not hang
• Enhance xteam reductions (with codegen). Support for integer data types.
• Fix for double _Complex scalars in target region, test/smoke-fails/double_complex_scalar now works. This test will move to smoke in next release.
• Support for target teams loop directive
• Force synchronous execution of regions controlled via OMPX_FORCE_SYNC_REGIONS
• New environment variable GPU_MAX_HW_QUEUES controls number of HSA queues created, default is 4. This change actually occurred in 16.0-1 but was not listed in release notes.

Errata:
(potential regressions from 16.0-1):

• Smoke test failures:
  clang-ifaces: core dump (gfx908)
  clang-337336: core dump gfx908)
  clang-325070: core dump (gfx908)

(potential regressions from 16.0-0):

• Performance decrease with lulesh
• Performance decrease with Nekbone
• Smoke test failures:
  flang-315870: (resolved by building this test case with cov5)
  managed_memory: segfault, when 2+ devices are present
• Hip example failure:
  device-lib
