Reland https://github.com/llvm/llvm-project/pull/150805 Shared libs build was broken. Add `${dialect_libs}` and `${conversion_libs}` to `MLIRRegisterAllExtensions` because it depends on `registerConvert***ToLLVMInterface` functions.
Standalone Transform Dialect Interpreter
This is an example of using the Transform dialect interpreter functionality standalone, that is, outside of the regular pass pipeline. The example is a
binary capable of processing MLIR source files similar to mlir-opt and other
optimizer drivers, with the entire transformation process driven by a Transform
dialect script. This script can be embedded into the source file or provided in
a separate MLIR source file.
Either the input module or the transform module must contain a top-level symbol
named __transform_main, which is used as the entry point to the transformation
script.
mlir-transform-opt payload_with_embedded_transform.mlir
mlir-transform-opt payload.mlir -transform=transform.mlir
The name of the entry point can be overridden using command-line options.
mlir-transform-opt payload-mlir -transform-entry-point=another_entry_point
Transform scripts can reference symbols defined in other source files, called libraries, which can be supplied to the binary through command-line options. Libraries will be embedded into the main transformation module by the tool and the interpreter will process everything as a single module. A debug option is available to see the contents of the transform module before it goes into the interpreter.
mlir-transform-opt payload.mlir -transform=transform.mlir \
-transform-library=external_definitions_1.mlir \
-transform-library=external_definitions_2.mlir \
-dump-library-module
