* Uses it to create a sample ChannelType.
* Requires: https://reviews.llvm.org/D101734
* See https://gist.github.com/stellaraccident/4a73e395e5cc68a5244c8d88dd291396 for a hacky sample of this working.
* Attributes would be incremantal on top of this.
With this, defining a custom type is pretty simple:
```
mlir_type_subclass(m, "ChannelType", circtESITypeIsAChannelType)
.def_static("get",
[](MlirType inner) {
return py::cast(circtESIChannelTypeGet(inner));
})
.def_property_readonly(
"inner", [](MlirType self) { return circtESIChannelGetInner(self); });
```
I feel good enough about this mechanism to suggest that we just upstream it as a public header and then refactor the builtin types to use it, deprecating PyConcreteType and PyConcreteAttribute. It isn't necessary to couple these together, though, and landing in circt could let us get some mileage on it first.
I'm aware that to the uninitiated, some of the pybind goo may seem magic, but this is actually the *less* magical way to do this: it isn't using any spooky Pybind11/C++ level sharing and is doing the exact same thing as if you literally spelled out "class MyType(mlir.ir.Type):" in Python -- but of course, meta-programming that in C++ is a bit thicker :) It also interops pretty well with the existing CAPI<->Python casters, making this (I think) a strict improvement over even what we have upstream.
One thing I didn't get to is a `DefaultingMlirContext` helper (ended up not needing it), but this would be pretty easy to add.
- Registers the SV passes when the 'circt' Python module is imported and the ESI passes when 'circt.esi' is imported.
- Adds a Python 'export_verilog' call.
- Enables LLVM 'pretty' stack traces for easier debugging. Makes assertion messages appear in Python instead of just crashing with no output.
This change aims to remove all instances of `using namespace mlir` from
our header files. Many types have been manually imported into the
`circt` namespace in `circt/Support/LLVM.h`. These types include all
core MLIR functionality types (IR, Diagnostic), utility types, rewrite
patterns and conversions, builtin IR types and attrs, and the module op.
Not imported were any operations (other than ModuleOp), matchers (e.g.
m_Zero), anything in the `impl` namespace, and interfaces. There are
some problems with interface code generation from ODS, so some
interfaces were imported.
Some further cleanup would be useful to remove the `mlir::` namespace
qualifier where we no longer need it.
