Introduction: carefully designed as the following components: libsupport - Basic support library, reused from LLVM. + libsystem - System abstraction library, reused from LLVM. libbasic - Diagnostics, SourceLocations, SourceBuffer abstraction, file system caching for input source files. This depends on libsupport and libsystem. + libast - Provides classes to represent the C AST, the C type system, builtin functions, and various helpers for analyzing and manipulating the AST (visitors, pretty printers, etc). This library depends on libbasic. - + + liblex - C/C++/ObjC lexing and preprocessing, identifier hash table, pragma handling, tokens, and macros. This depends on libbasic. + libparse - C (for now) parsing and local semantic analysis. This library invokes coarse-grained 'Actions' provided by the client to do stuff (e.g. libsema builds ASTs). This depends on liblex. + libsema - Provides a set of parser actions to build a standardized AST for programs. AST's are 'streamed' out a top-level declaration at a time, allowing clients to use decl-at-a-time processing, build up entire translation units, or even build 'whole program' ASTs depending on how they use the APIs. This depends on libast and libparse. - + + librewrite - Fast, scalable rewriting of source code. This operates on + on the raw syntactic text of source code, allowing a client + to insert and delete text in very large source files using + the same source location information embedded in ASTs. This + is intended to be a low-level API that is useful for + higher-level clients and libraries such as code refactoring. + + libanalysis - Source-level dataflow analysis useful for performing analyses + such as computing live variables. It also includes a + path-sensitive "graph-reachability" engine for writing + analyses that reason about different possible paths of + execution through source code. This is currently being + employ to write a set of checks for finding bugs in software. + libcodegen - Lower the AST to LLVM IR for optimization & codegen. Depends on libast. + clang - An example driver, client of the libraries at various levels. This depends on all these libraries, and on LLVM VMCore. |
