Here we start restructuring the the schemas YAML such that it
contains a top-level `version` field. In this commit we only modify
the YAML, the build system changes will come later, to avoid
enormous commits.
In this commit we instruct the build system to use the unified schema
files instead of collecting the `TUPLE-TREE-YAML` comments.
The fixes to C++ files are necessary because they depend on the order
of the fields in the schema, which was changed.
These schema files are currently generated at build time by
collecting various TUPLE-TREE-YAML comments using the
`extract_yaml.py` script. In this commit we move them to the codebase
but we don't use them yet, this will be done at a later commit for
the sake of readability.
This commit introduces new tags to specify how LLVMContainer should
deduplicate sets of equivalent functions, typically managed by an
`OpaqueFunctionPool`.
This commit switches the approach with which we run the ABI analyses: we
now run them until we reach a fixed point. This enables proper
interprocedural propagation of arguments and return values.
Basically, we now inject reads before call sites, so that, if a function
immediately calls another one, the arguments of the callee are
propagated to the caller.
This commit also updates the logic with which we propagate function
prototypes (and names) to callers. The main advantage of this, is that
function wrappers (in particular, PLT entries) now have the same name as
the function they wrap.
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>())`.
This is done mainly so that downstream passes do not need to run
`CollectCFG` to store information that has already been computed but not
serialized.
This come at the cost of computing the CFG also of functions we don't
want to analyze in `DetectABI`.
