- increase version requirement for nanobind to reflect MLIR requirements for stubgen - work around the bug in MLIR installation not including the generated stubs by pre-generating them - update successor interfaces - update amdgpu.mfma syntax - account for arith.andi folder that prevents the operation from being created in the first place Signed-off-by: Alex Zinenko <git@ozinenko.com>
