[PATCH] D49915: [IR] Add a boolean field in DILocation to know if a line must covered or not

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

I agree, this patch needs serialization through bitcode and IR before it can land.

DILocation isn't only used for coverage, I think this should probably be a more general purpose flag, like "isImplicitCode", to indicate that the code was generated as part of a destructor cleanup, an epilogue, or something else that requires the compiler to generate IR that isn't obviously attributed to user source code. Then GCOV can decide for itself how it wants to generate coverage.
