    `The AST [¶](https://mlir.llvm.org/docs/Tutorials/Toy/Ch-1/#the-ast)

The AST from the above code is fairly straightforward; here is a dump of it:

Module:
  Function 
    Proto 'multiply_transpose' @test/Examples/Toy/Ch1/ast.toy:4:1

          Call 'transpose' [ @test/Examples/Toy/Ch1/ast.toy:5:25
            var: b @test/Examples/Toy/Ch1/ast.toy:5:35

    } // Block
  Function

You can reproduce this result and play with the example in the examples/toy/Ch1/ directory; try running path/to/BUILD/bin/toyc-ch1 test/Examples/Toy/Ch1/ast.toy -emit=ast.`

found at https://mlir.llvm.org/docs/Tutorials/Toy/Ch-1/ 

I built MLIR correctly but don't see a `/bin/toyc-ch1` directory anywhere.  

I know a tiny bit of LLVM from school but should I be doing the Kaleidoscope tutorial before attempting anything in MLIR?  Ie. for learning is LLVM a prerequisite for MLIR?
