      Add BuildMlirFromTosaFile API · 04992e45
      Tai Ly authored 
      

This BuildMlirFromTosaFile API deserializes a tosa fbs or
json file and returns a mlir module as OwningOpRef<ModuleOp>

This also refactors the existing deserialization passes
to use the new API, and then copy the deserialized module's
main function into the existing function, and copy all
attributes of the new function and new module into the
existing function and module.

This allows testing of the new API by running deserialization
passes.

Here is an example showing the attributes on the deserialized
module and functions:

module attributes {tf_saved_model.semantics, tosa.description = "Tosa FBS Converted", tosa.fbs_version = "0.70.0d"} {
  func.func @main(%arg0: tensor<1x256x256x3xui8> {tf_saved_model.index_path = ["input_0"]}) -> (tensor<1x1x17x3xf32> {tf_saved_model.index_path = ["output_0"]}) attributes {tf.entry_function = {inputs = "tosa_de
serialized_input_0:0", outputs = "tosa_deserialized_output_0:0"}, tf_saved_model.exported_names = ["tosa_deserialized"]} {

      serialize/deserialize while/if ops using regions · 8ffce6d6
      Tai Ly authored 
      

This changes serialization and deserialization of while and if ops
to use regions instead of blocks.

also changed deserialization to preserve original ordering such that:
tosa1->deserialize->serialize->tosa2 => tosa1 == tosa2 most of the time.

      Add RegionBuilder to TOSA MLIR Translator · ab75f53f
      Jerry-Ge authored 
      

Rationale for making this change:
- The original design only supports a single basicBlock which is no
longer functionaly enough to support Control Flow operators like WhileOp
or IFOp
- Added another layer of abstraction of Region to support multiple
basicBlocks + other corresponding fixes
- There are other companion patches to make the above proposal work
  - Serialization Lib: Add TosaSerializationRegion to serialization_lib
  - Reference Model: Reference model update for control flow
