Subject: Inferred framework modules automatically export anything they import
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=209977c4d809914a20fd44873876c76cf972a56d;p=clang

Inferred framework modules automatically export anything they import
(i.e., 'export *'), to better match the semantics of headers.
