Why the sandbox depends on Clang and its tools?

[lorenzo chelini]

Dear All,
I wonder why the sandbox builds also Clang and Clang tools. Why not MLIR only?
See:

I think they are not built by default. The script actually builds only a subset of the targets.

cf here:

It seems like alps used clang?

You are at the source to figure that out :).

I have been building more things than strictly necessary so that the tools/llvm_mca.py script is functional.
If it poses a problem, feel free to add a new flag and turn off by default.

Thanks, both.
