Link to the failing linux-selfhost-modules bot:
http://lab.llvm.org:8011/builders/clang-x86_64-linux-selfhost-modules/builds/2728
In ReorderFieldsAction.cpp
The linkage of
> @_ZN5clang12ast_matchersL10recordDeclE = internal constant
> %"class.clang::ast_matchers::internal::VariadicDynCastAllOfMatcher.916"
> undef, align 1
changed to
> @_ZN5clang12ast_matchersL10recordDeclE = external global
> %"class.clang::ast_matchers::internal::VariadicDynCastAllOfMatcher.847",
> align 1
We should figure out what went wrong there.
