Subject: Make ChainedIncludesSource an ExternalSemaSource, otherwise initialization of the... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ce0682ff4647b885d41847b0f97918504282c2e8;p=clang

Make ChainedIncludesSource an ExternalSemaSource, otherwise initialization of the ASTReader is incomplete, leading to errors like not realizing std::type_info is already defined.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128664 91177308-0d34-0410-b5e6-96231b3b80d8
