Adds support for CFG conversion and conversion to LLVM IR for
`omp.private` ops. This bridges a gap between FIR and LLVM to provide
more support for lowering `omp.private` ops for things like
allocatables.
…ted. (#89998)" (#90250)
This partially reverts commit 7aedd7dc754c74a49fe84ed2640e269c25414087.
This change removes calls to the deprecated member functions. It does
not mark the functions deprecated yet and does not disable the
deprecation warning in TypeSwitch. This seems to cause problems with
MSVC.
This PR extracts `FIROpConversion` and `FIROpAndTypeConversion`
templated base patterns to a header file. All the functions from
FIROpConversion that do not require the template argument are moved to a
base class named `ConvertFIRToLLVMPattern`.
This move is done so the `FIROpConversion` pattern and all its utility
functions can be reused outside of the codegen pass.
For the most part the code is only moved to the new files and not
modified. The only update is that addition of the PatternBenefit
argument with a default value to the constructor so it can be forwarded
to the `ConversionPattern` ctor.
This split is done in a similar way for the `ConvertOpToLLVMPattern`
base pattern that is based on the `ConvertToLLVMPattern` base class in
`mlir/include/mlir/Conversion/LLVMCommon/Pattern.h`.
