New Revision: 342827<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=342827&view=rev" rel="noreferrer" target="_blank">http://llvm.org/viewvc/llvm-project?rev=342827&view=rev</a><br>
Log:<br>
Fix modules build with shared library.<br>
<br>
r341994 caused clangAnalysis to pull all of the AST matchers<br>
library into clang. Due to inline key functions in the headers,<br>
importing the AST matchers library gives a link dependency on the<br>
AST matchers (and thus the AST), which clang should not<br>
have.<br>
<br>
This patch works around the issues by excluding the offending<br>
libclangAnalysis header in the modulemap.<br>
