Stack from ghstack (oldest at bottom):
Currently, there's two cases where we are not allowed to change the strides (e.g. padding, honor channels-last preference) of a node during
GraphLowering.run_node():as_strided, the result's strides must matchnode.meta["val"].stride().Currently, we use
is_input_for_as_stridedandis_user_visibleto keep track of these cases. The code is rather confusing and would likely get worse if we introduce new sources of stride requirements.This PR refactors the above logic into
get_stride_requirement. If it returns a stride,GraphLowering.run_node()will honor it.Maybe relevant to #137979
