[PATCH] D146338: [MSVC compatibility][dllimport/dllexport][PS] Allow dllexport/dllimport for classes with UniqueExternalLinkage

[Wolfgang Pieb via Phabricator via cfe-commits]

wolfgangp updated this revision to Diff 507428.
wolfgangp added a comment.

Instead of suppressing the error message we drop the dllimport/dllexport attribute when we see that a class has UniqueExternal linkage. This will suppress exporting or importing any members, which could not be accessed outside the TU anyway.
