iree stable candidate-20240828.999

Major changes:

• Compiled artifacts (.vmfb files) from before this release are not compatible with the runtime from this release. Ensure your runtime and compiler are both up to date if you get errors loading files. Recent support for reusable/indirect command buffers made the HAL APIs simpler now, though out of tree compiler targets and HAL drivers may need to adapt to:

  • 5add66f changed the HAL version from 2 to 3.
  • 8dc6820 changed the HAL version from 3 to 4.
  • c77a5f5 changed the HAL version from 4 to 5.

• Several compiler flags were renamed in c44d29b:

  Before	After
  --iree-hal-cuda-llvm-target-arch	--iree-cuda-target
  --iree-hal-cuda-llvm-target-feature	--iree-cuda-target-features
  --iree-rocm-target-chip	--iree-hip-target
  --iree-rocm-target-features	--iree-hip-target-features
  --iree-vulkan-target-triple	--iree-vulkan-target
  --iree-hal-cuda-*	--iree-cuda-*
  --iree-rocm-*	--iree-hip-*

In development features:

• Support for data-tiling on GPU targets is in progress.
• The C++ attention pipeline is continuing to mature. It will replace the transform dialect attention pipeline.
