[PATCH] D87987: [llvm-objcopy][NFC] allow to redefine error handling.

[James Henderson via Phabricator via llvm-commits]

jhenderson added a comment.

Do we actually have any non-fatal errors in llvm-objcopy etc currently? If not, I think a better approach would be to simply bubble up the errors via Expected and Error usage, and handle the failures in the client code directly. The client code could then choose to either report them as errors (or warnings) and/or abort what it was doing. I imagine in the case of dwarfutil, you'd be best off aborting optimizing a given CU's debug data if it looked dodgy somehow, in which case, you don't need to distinguish between different classes of errors. This is the approach we take in our downstream port for our debug line rewriting that we've implemented.
