unregistered operation 'migraphx.max' found in dialect ('migraphx')

[shivadbhavsar]

MLIR attention does not seem to support the pointwise max operation, need to add check for it in the fuse_mlir pass.

Adjacent problem to #3439. Occurs when compiling the same model using mlir attention.

We probably need to add this operator to mlir, but it still is probably good to check for supported pointwise before fusing attention.

[shivadbhavsar]

Agreed, is that a change in migraphx or is that something mlir needs to support first?

[pfultz2]

Its a change that needs to happen in mlir, but it should be simple to add.
