Before the change:
```

```
After the change:
```
c10::Type t = ivalue.type();
c10::DynamicType d = ivalue.type<c10::DynamicType>(); // new path
```
The new path will be adopted in PyTorch Lite Interpreter to support lightweight type reflection. Note that type getters are selected at compile time so no performance overhead. The benefits of having a DynamicType will be elaborated in a separate document, but in short, DynamicType provides an isolated type system for controlling binary size bloat, and shrink down ~20 supported Type symbols into one so that the size taken by specializations and function name symbols are greatly reduced.
Lite Interpreter should only use the `<DynamicType>` variant of the interfaces from aten, to reduce binary size.

JIT type and IValue have a mutual dependency because of various reasons today. It makes things worse when we have `jit_type.h` and `ivalue.h` mutually include each other, causing non deterministic name resolutions at different translation units, preventing us safely use symbols from `jit_type.h` in `ivalue.h` . This diff doesn't address the mutual dependency between JIT type and IValue at linking level, but at header level.
We choose to remove include of `ivalue.h` from `jit_type.h` because it's way harder to make a type-free header for IValue. The way we achieve this is by removing EnumType (which is the only type depending on IValue in JIT types) from `jit_type.h`, and let downstream users to specifiy an explicit `enum_type.h` as needed. We also move some IValue inline member function definitions back to `ivalue_inl.h` so that `jit_type.h` doesn't need IValue definition to be present.
We also remove a seemingly accidental include of `jit_type.h` from `ATen/core/List_inl.h` so that `ivalue.h` can include `jit_type.h` directly, otherwise due to another mutual inclusion between `ivalue.h` and `List_inl.h` we can still get nondeterministic behavior.

mobile::Function should inherit from jit::Function, because for interface call support, we need an abstract jit::Function type stored in corresponding ClassTypes, so that we can look up methods in there. Previously mobile::Function is implemented separately which prevents this. Since we get rid of all the unneeded virtual methods from jit::Function, we can inherit from torch::jit::Function without too much cost.
NOTE that torch::jit::Function is already in dependency because we need it to support custom class call. We should be able to use Function uniformly without looking into whether it's a builtin function or mobile::Function.

This diff changes the way operator profiling is done in lite predictor
benchmarking binary.
Instead of using custom callbacks it uses KinetoEdgeCPUProfiler to profile
events and then generate operator level metric from it.
Since KinetoEvents do not contain cpu clock time, now we report only wallclock
time.
This unifies various profiling effort that we have for benchmarking purpose. In
production we will still use observer based mechanism, but the advantage of
using kineto profiler is that we get few other things for free, such as:
chrome trace generation.
operator level memory profiling (to be added)
flop counts (to be added)
Furthermore possible we can use python post processing script to parse chrome
trace and generate output similar to torch.profiler. (To be done)
Furthermore removes some tests from test_lite_interpreter.cpp which were testing module hierarchy in debug info. They should be covered by test_mobile_profiler.cpp.

handles and symbolicate exception callstack thrown from backend.
Objective of this diff is to achieve improve error reporting when
exceptions are raised from lowered backend. We would effectively like to
get the same model level stack trace that you would get without having
lowered some module to backend.
For example:
```
class AA(nn.Module):
def forward(self, x, y):
return x + y
class A(nn.Module):
def __init__(...):
self.AA0 = AA()
def forward(self, x, y):
return self.AA0.forward(x, y) + 3
class B(nn.Module):
def forward(self, x):
return x + 2
class C(nn.Module):
def __init__(...):
self.A0 = A()
self.B0 = B()
def forward(self, x, y):
return self.A0.forward(x, y) + self.B0.forward(x)
```
If the we then do C().forward(torch.rand((2,3)), torch.rand(14,2))) we
will likely see error stack like:
```
C++ exception with description "The following operation failed in the TorchScript interpreter.
Traceback of TorchScript (most recent call last):
File "<string>", line 3, in forward
def forward(self, x, y):
return self.A0.forward(x, y) + self.B0.forward(x)
~~~~~~~~~~~~~~~ <--- HERE
File "<string>", line 3, in forward
def forward(self, x, y):
return self.AA0.forward(x, y) + 3
~~~~~~~~~~~~~~~~ <--- HERE
File "<string>", line 3, in forward
def forward(self, x, y):
return x + y
~~~~~ <--- HERE
```
We would like to see the same error stack if we lowered C.A0 to some
backend.
With this diff we get something like:
```
Module hierarchy:top(C).A0(backend_with_compiler_demoLoweredModule).AA0(AA)
Traceback of TorchScript (most recent call last):
File "<string>", line 3, in FunctionName_UNKNOWN
def forward(self, x, y):
return self.A0.forward(x, y) + self.B0.forward(x)
~~~~~~~~~~~~~~~ <--- HERE

typed_inputs: List[Any] = [x, y, ]
if self.__backend.is_available() :

~~~~~~~~~~~~~~~~~~~~~~ <--- HERE

return _0

return self.AA0.forward(x, y) + 3
~~~~~~~~~~~~~~~~ <--- HERE
File "<string>", line 3, in FunctionName_UNKNOWN
def forward(self, x, y):
return x + y
~~~~~ <--- HERE
```
This is achieved in 3 parts:
Part 1:
A. BackendDebugInfoRecorder:
During backend lowering, in `to_backend`, before calling the preprocess
function corresponding to the backend. This will facilitate recording of
debug info (such as source range + inlined callstack) for the lowered module.
B. Instantiate WithBackendDebugInfoRecorder with BackendDebugInfoRecorder.
This initializes thread local pointer to BackendDebugInfoRecorder.
C. generate_debug_handles:
In preprocess function, the backend will call generate_debug_handles
for each method being lowered separately. generate_debug_handles
takes `Graph` of the method being lowered and returns a map
of Node*-to-debug_handles. Backend is responsible for storing debug
handles appropriately so as to raise exception (and later profiling)
using debug handles when the exception being raised corresponds to
particular Node that was lowered.
Inside generate_debug_handles, we will query the current
BackendDebugHandleInfoRecorder, that is issuing debug handles. This debug
handle manager will issue debug handles as well as record
debug_handles-to-<source range, inlined callstack> map.
D. Back in `to_backend`, once the preprocess function is has finished
lowering the module, we will call `stopRecord` on
BackendDebugInfoRecorder. This will return the debug info map. This
debug info is then stored inside the lowered module.
Part 2:
Serialization:
During serialization for bytecode (lite interpreter), we will do two
things:
1. Extract all the source ranges that are contained inside
debug_handles-to-<source range, inlined callstack> map for lowered
module. This will be source range corresponding to debug handles,
including what is there is inlined callstack. Since we replaced original
module with lowered module, we wont be serializing code for the original
module and thus no source range. That is why the source range will have
to be stored separately. We will lump all the source ranges for all the
lowered modules in one single debug_pkl file.
2. Then we will serialize debug_handles-to-<source range, inlined
callstack> map.
Now during deserialization we will be able to reconstruct
debug_handles-to-<source range, inlined callstack> map. Given all
debug_handles are unique we would not need any module information.

Tests are added in test_backend.cpp

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/54284
In order to bring mobile deployment, via lite interpreter, on feature
parity with JIT, with respect model level debug information we must make
model level debug information available to mobile runtime.
At the moment, model level debug information is stored in SourceRange
which associates node's of graph to where the come from in original
python source code.
This information is serialized as part of debug_pkl and deserialized
when JIT loads the model and reads the model code.
On lite interpreter, we do not have access to all the functionality of
JIT and hence we cannot load model in the same way as JIT, by reading
code, constructing module hierarchy and graph corresponding module
methods etc. Instead in, lite interpreter, only bytecode corresonding to
the compiled graph, Code, is saved.
Thus in order to annotate OPs in the bytecode with equivalent
SourceRange information we do the following:
1. During model serialization, we create a unique tag for each source
range of the model.
2. Create a map of <SourceRange, tag>
3. During debug_pkl serialization we save tag along with SourceRange, on
top of byte offset.
4. During bytecode generation, the methods of the top module are
lowered. During this process methods are inlined. In the inlined graph,
when the node of a graph is lowered to bytecode, we query node's source
range and look it up against the map.
5. Resulting source range tag is serialized in module_debug_info.
6. During model deserialization, we read all the debug_pkl records in
the archieve and create a map of <tag, SourceRange>
7. This map can be used to find source code information.
During mobile runtime:
1. We read all the debug_pkl records and create <tag=debug_handle,
SourceRange> map.
1.1 This map, MobileDebugInfo, is a member of mobile Module.
2. Interpreter catches appropriate exceptions and sets the thread local
debug handle and rethrows the exception.
3. In Function's run method we catch exception and query current debug
handle where the exception happened.
4. Query MobileDebugInfo with debug handle to retrieve source range and
augment error with source range info.
This information is still incomplete as it does not contain entire
callstack.
In the following diffs we will serialize InlinedCallStack directly.
Note that compilation is gated by SYMBOLICATE_MOBILE_DEBUG_HANDLE macro,
so that mobile builds can avoid building MobileDebugInfo, source range
and source range pickler/unpickler. Later we will add path where, if
building without debug support stack trace will contain only debug
handles. They can be symbolicated later.
Test Plan:
Ported bunch of source range tests from test_jit.py. Added on more test
in test_lite_interpreter.py

dictConstruct doesn't need to make its caller have a `shared_ptr<DictType>`. It also doesn't need to do extra `shared_ptr` copies into the `key_type` and `value_type` locals.

If we don't constrain ourselves to use `torch::jit::pop`, we can avoid copying a string or moving IValues around.

This resulted in [S22350](https://www.internalfb.com/intern/sevmanager/view/s/223540), which caused truoble on Android.
1. The Python has a call to `warnings.warn()`, which resulted in code generated to emit the `WARN` instruction on lite-interpreter.
2. The code for handling that instruction/op-code popped off the value in a call to the `TORCH_WARN()` *macro*.
3. This macro conditionally compiled out evaluation of the arguments if `STRIP_ERROR_MESSAGES` was defined, which resulted in the stack not getting popped, and the lite-interpreter returning the last pushed value on to the stack.
I've attempted to re-produce it using this python code: {P243842428}

(Note: this ignores all push blocking failures!)
Test Plan:
Created a new unit test to re-produce the failure in the test. Was able to do so locally using the following command:
```
buck test -c pt.strip_error_messages=1 //xplat/caffe2:test_s223540
```
However, since `pt.strip_error_messages=0` for dev and continuous builds, I have had to check in a separate contbuild config to try and trigger this failure on contbuild.

Add the missing parts to support to_backend modules by lite interpreter.
1. Add ISINSTANCE instruction support, which is used in to_backend for output type check.
2. Bypass lite interpreter's type parser by checking the qualified name. If it starts with "torch.jit", use the same type resolver as nn module (starting with "__torch__").
Tests
Mobile module is serialized and loaded in ```BackendTest.TestCompiler```. The results are compared to those from original torchscript module.

torchbind is a convenient way to include custom class to both python and torchscript. CREATE_OBJECT is used to create an object of custom class.
CREATE_OBJECT was not supported by lite interpreter. The major reason was that for custom class directly defined in Python, there's no language parser in lite interpreter. It's still the case. However, for torchbind classes that are defined in C++, a python/torchscript parser is not needed.
This diff is to support the case of torchbind custom classes.
1. The class type can be resolved at import level.
2. If the class is not the supported torchbind class, an error message is provided at export stage. Workaround is also suggested.
3. Unit tests. C++: ```LiteInterpreterTest::BuiltinClass``` is added as an end-to-end test on supported class. Python: ```test_unsupported_createobject``` is changed to ```test_unsupported_classtype``` to test unsupported classes.
