clang Tooling, and more specifically Refactoring/Rename, have support code to extract source locations given a Unified Symbol Resolution set. This support code is used by clang-rename and other tools that might not be in the tree. Currently field designated initializer are not supported. So, renaming S::a to S::b in this code: S s = { .a = 10 }; will not extract the field designated initializer for a (the 'a' after the dot). This patch adds support for field designated initialized to RecursiveSymbolVisitor and RenameLocFinder that is used in createRenameAtomicChanges.
