TODO:
- Add more cases
- Currently, we just set vec to 4 to make the basic cases pass
Issue:
- the vec in shared layout is different compared to master branch
- when vec=1, it encounters CUDA misalignment error, it doesn't work in
master branch as well
- when setting vec to the value identical to master branch, the MMA
works
This PR
- apply minimal modification to decouple the Dot helper related code
from TritonGPUToLLVM.cpp to a separate local header file to make it
easier to share some data structure for Dot
- add some patch necessary for transA and transB
- add some patch necessary for MMA v1 execution in backend
