* [Syntax] Do not glue multiple empty PP expansions to a single mappingIlya Biryukov2019-06-241-53/+130
| | | | | | | | | | | | | | | | | | | | | Summary: This change makes sure we have a single mapping for each macro expansion, even if the result of expansion was empty. To achieve that, we take information from PPCallbacks::MacroExpands into account. Previously we relied only on source locations of expanded tokens.

* [Syntax] Introduce TokenBuffer, start clangToolingSyntax libraryIlya Biryukov2019-05-202-0/+519
Summary: TokenBuffer stores the list of tokens for a file obtained after preprocessing. This is a base building block for syntax trees, see [1] for the full proposal on syntax trees. This commits also starts a new sub-library of ClangTooling, which would be the home for the syntax trees and syntax-tree-based refactoring utilities.
