[PATCH] D14558: [llvm-profdata] Add check for text profile formats and improve error reporting

[David Li via llvm-commits]

davidxl added a comment.

The only limitation here is that when a sample text file is passed to llvm-profdata tool without -sample option, the tool can still not give very useful information -- supporting that requires non trivial refactoring so that 'hasFormat' interfaces are moved to a common place.  Probably not worth the effort.

Looks good to me. Watch out for more comments post-commit.
