[PATCH] D95924: [Example][NFC} Add testcase for BrainF HelloWorld

[Tim Northover via Phabricator via llvm-commits]

> I doubt it. because when I run test files separately they are passing. The issue occurs when I merge them in a single file.

That adds more perturbations to the initial tape state which is enough to break the "Hello World" output.

> Could you please suggest RUN line by example, I tried some configurations, It doesn't work on my system.

This worked for me:

  [
  ; RUN: BrainF %s -o - | llvm-dis | FileCheck --check-prefix=CHECK %s
  ; RUN: BrainF %s -o - | lli 2>&1 | FileCheck --check-prefix=EXEC %s
  ]

Though it seems there's extra output from the CHECK lines too. It might actually be better to put the BF code in its own completely separate file (this is usually put in an `Inputs` subdirectory and referred to as `%p/Inputs/helloworld.bf` instead of the test name `%s`).
