* Create a project for graph optimizer.
Move optimizer related code to the folder optimizer.
* Fix build failures.
* rebase and fix build failures.
* fix build failure.
* fix build failure with cuda path.
* fix python build failure.
* Move two transformers(memcpy and insert_cast) from framework to optimizer.
* rebase.
* SessionState should not depend on optimizer.
* Add Recurse method to GraphTransformer.
Move GraphTransformer::Apply to ApplyImpl and make private.
Add non-virtual GraphTransformer::Apply method to handle calling Graph::Resolve in a more consistent manner.
Create MemcpyTransformer GraphTransformer to handle memcpy operations on subgraphs in a more standard way.
* Checkpoint
* Make the subgraph insert less verbose
* Add graph nesting level to transformer ApplyImpl
Tweak cast transformer to recurse nicely and avoid unnecessary Resolve calls by splitting out the duplicate removal into a separate transformer.
Decouple memcpy transformer from ExecutionProviders and minimise what's in the header.
* Recurse into subgraphs inside GraphPartitioner
* Update a couple of new transformers
* Check Recurse return value.
* Cleanup some memory management in inference session by moving some things into SessionState
* Add deleted flag to rewrite rules so we stop processing nodes that are removed.
Remove some (most likely) unnecessary Resolve calls. As we always call Resolve for a graph modified by a transformer there's generally no need for the transformer to do it.
* Minor cleanups.
* Add some extra usage information to the comments in GraphTransformer.
* Address PR comments
* Separate out the NodeArg index information from ExecutionFrame so it is only calculated once.
* Skip copy to/from device if only CPU execution provider is registered.
Cleanups.
* Address PR comments.
Clean up a few areas.
* Fix Linux build error
Rewrite rule that eliminates slice operators when they are redundant (i.e., when they preserve the whole input).
Re-implementation of the identity elimination rule using the latest Graph API.
* refactor kernel registry to make it a little bit more readable.
* update
* update cudaexecutionprovider
* fix build break
* fix comments
* fix build break
* Make OrtAllocator not be reference counted
* Make the allocator interface more type safe
* Fix build break
* Build break fix
* Build break fix
* Mistake in previous build fix.
* Fix review comments + build break
* Missed the export symbols
* C specific error, need 'struct' keyword in one case.
* Function calling OrtReleaseObject instead of OrtReleaseEnv
* merge function compile interface
* fix build error
* fix linux build break
* fix static cast issue; fix clang style
* fix argument change
* use alignment allocation;fix comments in pr
* fix linux break
* apply clang format
* rename according to comments in pr
* rename according to pr comments;remove useless file
* remove the need_compile flag
* avoid passing whole session state
* More API changes, remove 'Inference' from function names. Remove enum values. Make Status match other types.
* Switch to bool instead of int, and remove stdbool
Applies to all public headers and macros, plus many internal ones. There are still some internal things with OnnxRuntime in the name, but this fixes all public functions & macros.
* Rename ONNXRUNTIME_API_STATUSCALL to ONNXRUNTIME_API_CALL since it's just for calling convention, there's no status return value implied.
* Missed a function
* remove input edges while removing a node.
* put comments on how to remove a node without using resolve.
* fix test failure
* fix test failure.
* fix format
* try to guess and fix mac ci failure.
* change add remove edge api.
* update IR
* update comments
* fix comments.
* Checkpoint.
* Add doco to graph.h and graph_base.h.
Change NodeConstIterator to return a reference to clearly advertise no nullptr's are going to be returned as it's only iterating valid Nodes.
Fix some code analysis warnings.
* Make a couple of APIs return a reference instead of a pointer as they never return nullptr.
* More doco and some minor naming cleanups.
* Cleanups
Couple more consistency changes.
* Fix CUDA test file
* Fix invalid line.
