[PATCH] D133480: [llvm-dwp] Get the DWO file using relative path instead of absolute path to make it work for distribution build

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

I don't think this is correct - the dwp tool might be run from a different directory than the equivalent comp_dir and so treating these as cwd-of-dwp-relative paths seems problematic.

I think the correct thing to do in the situation described is for the compilation to use -fdebug-compilation-dir <https://clang.llvm.org/docs/ClangCommandLineReference.html#cmdoption-clang-fdebug-compilation-dir> to make the debug info portable - this will also ensure that a debugger can find the source and find the .dwo files even if they aren't packaged into a .dwp.
