AliasAnalysisKind::CONSERVATIVE/FROM_SCHEMA (#22175)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/22175
- Rename AliasAnalysisKind::DEFAULT to AliasAnalysisKind::CONSERVATIVE
- Introduce AliasAnalysisKind::FROM_SCHEMA that means the alias annotations of the schema should be honored
- Introduce AliasAnalysisKind::INTERNAL_SPECIAL_CASE to be able to run assertions that internal special cased ops are treated correctly
- aten:: and prim:: ops are not treated as special cases anymore, but just use AliasAnalysisKind::FROM_SCHEMA
- There's a set of assertions to ensure that aten:: and prim:: ops are all correctly set up to use AliasAnalysisKind::FROM_SCHEMA. Once this PR lands and passes all tests, we will remove those assertions and open up for the possibility of different AliasAnalysisKind settings for aten:: and prim:: ops
