This is required for traversing certain types (like function pointer types). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@271927 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/LibASTMatchersReference.html | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'docs/LibASTMatchersReference.html') diff --git a/docs/LibASTMatchersReference.html b/docs/LibASTMatchersReference.html index 433ba7843f..b944fc6b7e 100644 --- a/docs/LibASTMatchersReference.html +++ b/docs/LibASTMatchersReference.html @@ -3521,6 +3521,10 @@ Example matches X, Y ChildT must be an AST base type.
