This PR fix a AST dump issue since https://github.com/llvm/llvm-project/pull/80001 When Clang dumps `CXXDefaultArgExpr`/`CXXDefaultInitExpr`, there has no recursively dump the complete `CXXDefaultArgExpr`/`CXXDefaultInitExpr`. Since this PR, Clang will recursively dump a `CXXDefaultArgExpr`/`CXXDefaultInitExpr` node, even if the node has no rewritten init. *Consider*: ``` struct A { int arr[1]; }; struct B { const A &a = A{{0}}; }; void test() { B b{}; } ``` *Before*: ``` `-FunctionDecl <line:9:1, line:11:1> line:9:6 test 'void ()' `-CompoundStmt <col:13, line:11:1> `-DeclStmt <line:10:3, col:8> `-VarDecl <col:3, col:7> col:5 b 'B' listinit `-InitListExpr <col:6, col:7> 'B' `-CXXDefaultInitExpr <col:7> 'const A' lvalue has rewritten init `-ExprWithCleanups <line:6:16, col:21> 'const A' lvalue ``` *After*: ``` `-FunctionDecl 0x15a9455a8 <line:9:1, line:11:1> line:9:6 test 'void ()' `-CompoundStmt 0x15a945850 <col:13, line:11:1> `-DeclStmt 0x15a945838 <line:10:3, col:8> `-VarDecl 0x15a945708 <col:3, col:7> col:5 b 'B' listinit `-InitListExpr 0x15a9457b0 <col:6, col:7> 'B' `-CXXDefaultInitExpr 0x15a9457f8 <col:7> 'const A' lvalue has rewritten init `-ExprWithCleanups 0x15a945568 <line:6:16, col:21> 'const A' lvalue `-MaterializeTemporaryExpr 0x15a945500 <col:16, col:21> 'const A' lvalue extended by Field 0x15a945160 'a' 'const A &' `-ImplicitCastExpr 0x15a9454e8 <col:16, col:21> 'const A' <NoOp> `-CXXFunctionalCastExpr 0x15a9454c0 <col:16, col:21> 'A' functional cast to A <NoOp> `-InitListExpr 0x15a9452c0 <col:17, col:21> 'A' `-InitListExpr 0x15a945308 <col:18, col:20> 'int[1]' `-IntegerLiteral 0x15a945210 <col:19> 'int' 0 ``` --------- Signed-off-by: yronglin <yronglin777@gmail.com>
