| AST Matchers |
| ------------ |
| The AST matcher functions were renamed to reflect the exact AST node names, |
| which is a breaking change to AST matching code. The following matchers were |
| affected: |
| |
| ======================= ============================ |
| Previous Matcher Name New Matcher Name |
| ======================= ============================ |
| recordDecl recordDecl and cxxRecordDecl |
| ctorInitializer cxxCtorInitializer |
| constructorDecl cxxConstructorDecl |
| destructorDecl cxxDestructorDecl |
| methodDecl cxxMethodDecl |
| conversionDecl cxxConversionDecl |
| memberCallExpr cxxMemberCallExpr |
| constructExpr cxxConstructExpr |
| unresolvedConstructExpr cxxUnresolvedConstructExpr |
| thisExpr cxxThisExpr |
| bindTemporaryExpr cxxBindTemporaryExpr |
| newExpr cxxNewExpr |
| deleteExpr cxxDeleteExpr |
| defaultArgExpr cxxDefaultArgExpr |

| ======================= ============================ |
| |
| recordDecl() previously matched AST nodes of type CXXRecordDecl, but now |
| matches AST nodes of type RecordDecl. If a CXXRecordDecl is required, use the |
| cxxRecordDecl() matcher instead. |
