Add a `Dirty` boolean to the `ContainerBase` class. This will be set to
true when the container mutates itself (e.g. remove, mergeBack, clear).
The dirty bit is reset when running `PipelineManager.store`.
At the moment this pipe is broken, because it claims to be producing
artifacts with function rank, while it only produces types.
This pipe should be extended and turned into a pipe that generates
the whole Clift module including functions from LLVM IR, and not just
types.
We should add an input LLVMContainer, and the run() method should first
import types, and then create the functions and their bodies.
For the time being the Pipe is removed from the pipeline.
The previous conversion from LLVM to MLIR was translating plain LLVM IR
to LLVM MLIR Dialect, as a preliminary step for further conversion from
LLVM MLIR Dialect to Clift.
This is not how things are expected to work anymore, so the old code is
now dead and can be removed.
A bug in revng allowed to use any TaggedFunctionKinds in place of any
other one. That bug has been fixed and the wrong usages in revng-c have
been updated.
- Add PrepareLLVMIRForMLIR Pass.
This Pass performs massaging of the LLVM IR
produced by revng so it can be parsed/accepted
for the LLVM MLIR Dialect.
- Introduce new pipeline branch: llvmir-to-mlir.yml.
- Add LLVMIRToMLIR step.
- Add ImportLLVMToMLIRPipe pipe.
