AOMP Release 0.6-1

Changes from 0.6-0 to 0.6-1:

• Disabled SILoadStoreOptimizer pass to work around 64 bit address calculation issue

• Added 6 new device APIs as extentions to OpenMP device apis

  • omp_ext_get_warp_id
  • omp_ext_get_lane_id
  • omp_ext_get_master_thread_id
  • omp_ext_get_smid
  • omp_ext_is_spmd_mode
  • omp_ext_get_active_threads_mask

• rtl get_launch_vals added, algorithm rewrite for threads, teams computation

  • Throttle code for teams and threads off by default, enabled with THREAD_TEAM_THROTTLE

• Added support for an LLC and OPT specific env-var AOMP_LLC_ARGS AOMP_OPT_ARGS

  • Allows adding compiler options to opt and llc via env-var, useful for triage, dumps, and debug.

• Added clang-unbundle-archive tool.

• Added support for device library archives in clang when using -l flag.

• Updated llvm-link to work with archives of .bc components

• Added new method AddStaticDeviceLibs to CommonArgs.cpp that searches for static device
  libraries using -l and -L command line options in a way similar to the search method used for
  host libraries including which directories to search for. The differences from host search are:

  • Searches look for names that specify the architecture and/or GPU
  • Searches look in the libdevice subdirectory of each host directory path
  • Searches look for filenames with .a suffix before searching for .bc suffix

• Cleanup of aomp build scripts including split of llvm component into llvm, clang, and lld.

• Fix where llvm-config is found during build

• Added installed binaries from llvm to help with clang lit testing

• New build script for comgr. This is not part of the compiler build yet. Developers and those building from source can run build_comgr.sh

• Do not build hip runtime for ppc and arm builds.

• Added two new smoke tests and improved automation of smoke tests

• Corrected mymcpu and mygpu for vega20
