This commit switches `model::Type::ID` from being a GUID to be a
progressive number, in order to make things easier for humans.
On top of this, this commit introduces the following changes:
* TypeCopier: import all the necessary PrimitiveTypes and improve
handling of CustomName.
* Move Kind as the last field of the key of each TupleTree type used in
an `UpcastablePointer`.
* Update the ground truth of tests to ignore the `CustomName` in favor
of focusing on `OriginalName`.
* Increase adoption of `model::Binary::makeType`, equivalent to
`Binary.recordNewType(makeType<model::*Type>())`.
`DocumentError`s are the inteded way of propagating errors from the
pipeline to the frontend when a location is required to inform the user
of the error whereabouts.
The control-flow graph and all its hierarchy components
have been moved from `model` to `efa`. The CFG is now
serialized onto the LLVM IR module as a metadata.
Model classes are now described by a YAML document, which is used to
generate C++ headers containing classes and all the boilerplate
required for YAML serialization/deserialization, usage in
SortedVectors, etc. See the README in include/revng/Model for more
info.
These functions can be used in conjunction to dump the Model on a
file during a gdb session, for example:
```
(gdb) p writeToFile(Model->toString(), "/tmp/model.yaml")
```
* Introduce some documentation for the model.
* Improve the way enums are serialized/deserialized.
* Mark certain fields of model data structures as optional.
* introduces some error messages during model validation.
This commit introduces the type system of the model along with several
various other improvements to the model and its users.
* Introduce the type system.
* Introduce possibility to tag certain fields in the model as to be
optional during YAML serialization.
* All the `Name` fields have been replaced in favor of `CustomName` plus
a `name` method that will use `CustomName` if available, or an
automatically generated name otherwise.
* Make TupleTreeReferences behavior more robust: now you either need to
have a valid pointer to `Root` and a `Path` or be default constructed
(`nullptr` for `Root` and an empty `Path`). Any other configuration is
invalid.
* The type system introduces `RawFunctionType`: this superseds the
previous way in which we were specifying arguments and return
values. Users of such information have been updated accordingly.
This commit drops the KeyTraits in favor of a std::any-like solution.
Basically, we type erase any key the user wants to employ, just exposing
a virtual version of the destructor, a comparison operator and a clone
primitive.
