There was a problem hiding this comment.
This line is not needed, it'll run the test a second time, the line at the top is enough.
What can be done though is adding the --split-input-file to mlir-opt and add // ----- separators between modules in the file.

I'm confused on the logic changes here. In what situation was this not previously converting nested operation to bytecode? (that's what writeBytecodeToFile does). It also looks like you've removed all of the actual bytecode writing, and now just generate placeholder strings for every operation: "bytecode_for_" << op->getName().getStringRef() << "\n".
Can you walk situation you're running into, and what you're trying to do? It feels like there may be some confusion here, given that this source file is for the MLIR Language Server and the test you've written is exercising mlir-opt (different code paths).
