0. Discussion

• Stop testing with typeguard:
  • Lack of ongoing maintenance / interest
  • Periodic issues arise, only noticed when sharding changes
  • Conclusion: remove if typeguard breaks again since we are no longer actively working on type annotations
• Discussion on LLVM pass plugin by passing around bitcode to "standalone" LLVM pass binary
• State of 0.57 (stuart)
• Starting release process for numba 0.57 and llvmlite 0.40
• Issues with performance from effectively not running -O3 twice (#8172).
  • Conclusion was to have a env var to restore the "old" behaviour.
• Updating mk_alloc to support Numba-Dpex compute follows data https://github.com/numba/numba/issues/8847
