Hi Saleem I just realize there can be an issue with this commit. This breaks the bitcode compatibility when LTO linking bitcode file produced by llvm-5.0 vs the older versions. Because the objc related module flag has the behavior Module::Error, simple whitespace changes will cause libLTO to error upon seeing different values.
I wish I caught this earlier so we can fix the issue before 5.0 released. Maybe we need another bitcode upgrade path to strip away all the whitespaces in "Objective-C Image Info Section" module flag?
