[PATCH] D61680: [X86] Avoid SFB - Fix inconsistent codegen with/without debug info

[Paul Robinson via Phabricator via llvm-commits]

probinson added a comment.

The point is not that a certain set of moves comes out, but that the *same* set of moves comes out regardless of debug info.
So, the test wants to have two copies of the same function, one with debug instructions and one without; and both functions should produce the same sequence of moves.

To keep the test from being really tedious, I am pretty sure you can run FileCheck twice and have each run look at a different function, with clever use of -D on the FileCheck command line. This probably means you have to capture the llc output in a file, but that's okay.
