This PR implements the semantics change to `torch._dynamo.error_on_graph_break`: - ~`torch.compile` now has a new `error_on_graph_break` kwarg that serves as a lower-priority toggle for erroring/continuing on graph breaks~ - `error_on_graph_break` is a new internal `torch.compile `setting that is lower-priority than `fullgraph`. It allows the user to toggle erroring/continuing on graph breaks. - `error_on_graph_break` does nothing when `fullgraph=True` - `error_on_graph_break` does NOT guarantee a single graph Followup [DONE]: need to change the programming model docs to reflect the 3 graph break modes for compilation: - `fullgraph=True`: enforce one graph, no graph breaks, cannot be toggled - `fullgraph=False, error_on_graph_break=True`: errors on graph breaks, latter can be toggled during compile time - `fullgraph=False, error_on_graph_break=False`: resumes tracing on graph breaks, latter can be toggled during compile time Pull Request resolved: https://github.com/pytorch/pytorch/pull/161747 Approved by: https://github.com/mlazos ghstack dependencies: #161739
