Can we pass to the harness a partially transformed file and execute only a partial pipeline? about iree-llvm-sandbox HOT 2 OPEN

This should be very easy to do today.
We've used https://github.com/google/iree-llvm-sandbox/blob/main/python/examples/core/transforms.py#L60 for the same purpose; you just want the string to be read from a file rather than pasted inline.

f = open ("foo.mlir", "r")
ir = f.readlines()

adding @ftynse to ensure recent refactorings are mindful of Inject / TransformationList interplay.

Test harness is ultimately about running the code, so we cannot just instruct it to produce unrunnable code. If you want human-in-the-loop, you can do something like print(P0.then(P1).then(P2)(your-module)), modify the code manually, parse it back and have an "expert" that does P3.then(P4).then(P5) on it passed to the harness. This should be fine as long as the ABI of the entry point remains the same.

For adventurous ones, it is possible to have a "transform" that prints the IR into a file and then popen's $EDITOR with that file for the user to edit before parsing it back.
