2010-04-05Clarify the ownership semantics of the Diagnostic object used byDouglas Gregor
ASTUnit. Previously, we would end up with use-after-free errors because the Diagnostic object would be creating in one place (say, CIndex) and its ownership would not be transferred into the ASTUnit.

2010-03-20Optimize region-of-interest based cursor walks through theDouglas Gregor
preprocessed entities by grouping preprocessed entities by file ID. This drastically improves performance of repeated clang_getCursor() calls local tests, although it is a bit ugly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99015 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Remove the capture, serialization, and deserialization of commentDouglas Gregor
ranges as part of the ASTContext. This code is not and was never used, but contributes ~250k to the size of the Cocoa.h precompiled header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99007 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Implement serialization and lazy deserialization of the preprocessingDouglas Gregor
record (which includes all macro instantiations and definitions). As with all lay deserialization, this introduces a new external source (here, an external preprocessing record source) that loads all of the preprocessed entities prior to iterating over the entities. The preprocessing record is an optional part of the precompiled header that is disabled by default (enabled with -detailed-preprocessing-record). When the preprocessor given to the PCH writer has a preprocessing record, that record is written into the PCH file. When the PCH reader is given a PCH file that contains a preprocessing record, it will be lazily loaded (which, effectively, implicitly adds -detailed-preprocessing-record). This is the first case where we have sections of the precompiled header that are added/removed based on a compilation flag, which is unfortunate. However, this data consumes ~550k in the PCH file for Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering this detailed preprocessing information, so it's too expensive to turn on by default. In the future, we should investigate a better encoding of this information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99002 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-18Introduce the notion of a "preprocessing record", which keeps track ofDouglas Gregor
the macro definitions and macro instantiations that are found during preprocessing. Preprocessing records are *not* generated by default; rather, we provide a PPCallbacks subclass that hooks into the existing callback mechanism to record this activity. The only client of preprocessing records is CIndex, which keeps track of macro definitions and instantations so that they can be exposed via cursors. At present, only token annotation uses these facilities, and only for macro instantiations; both will change in the near future. However, with this change, token annotation properly annotates macro instantiations that do not produce any tokens and instantiations of macros that are later undef'd, improving our consistency. Preprocessing directives that are not macro definitions are still handled by clang_annotateTokens() via re-lexing, so that we don't have to track every preprocessing directive in the preprocessing record. Performance impact of preprocessing records is still TBD, although it is limited to CIndex and therefore out of the path of the main compiler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98836 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-16Fix header-search problems with precompiled headers, where theDouglas Gregor
presence or absence of header map arguments when using the precompiled header would cause Clang to get confused about which headers had already been included/imported, along with their controlling macros. The fundamental problem is that the serialization of the header search information was relying on the UIDs of FileEntry objects at PCH generation time and PCH load time to be equivalent, which effectively means that we had to probe the same files in the same order. Differing header map arguments caused an extra FileEntry lookup, but it's easy to imagine other minor command-line arguments triggering this problem. Header-search information is now encoded along with the source-location entry for a file, so that we register information about a file's properties as a header at the same time we create the FileEntry for that file. Fixes <rdar://problem/7743243>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98636 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-10Create a new InjectedClassNameType to represent bare-word references to the John McCall
injected class name of a class template or class template partial specialization. This is a non-canonical type; the canonical type is still a template specialization type. This becomes the TypeForDecl of the pattern declaration, which cleans up some amount of code (and complicates some other parts, but whatever). Fixes PR6326 and probably a few others, primarily by re-establishing a few invariants about TypeLoc sizes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98134 91177308-0d34-0410-b5e6-96231b3b80d8

This is the way I would like to move the frontend function towards -- distinct pieces of functionality should be exposed only via FrontendAction implementations which have clean and relatively-stable APIs.

2010-02-18Rework how CIndex handles diagnostics. Rather than using a callback,Douglas Gregor
we attach diagnostics to translation units and code-completion results, so they can be queried at any time. To facilitate this, the new StoredDiagnostic class stores a diagnostic in a serializable/deserializable form, and ASTUnit knows how to capture diagnostics in this stored form. CIndex's CXDiagnostic is a thin wrapper around StoredDiagnostic, providing a C interface to stored or de-serialized diagnostics. I've XFAIL'd one test case temporarily, because currently we end up storing diagnostics in an ASTUnit that's never returned to the user (because it contains errors). I'll introduce a temporary fix for this soon; the real fix will be to allow us to return and query invalid ASTs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96592 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-14Change LLVMConventionsChecker to accept an entire translation unit insteadTed Kremenek
of operating on each code decl. This exposes two flaws in AnalysisConsumer that should eventually be fixed: (1) It is not possible to associate multiple "actions" with a single command line argument. This will require the notion of an "analysis" group, and possibly tablegen support. (although eventually we want to support dynamically loading analyses as well) (2) AnalysisConsumer may not actually be scanning the declarations in namespaces. We'll experiment first in LLVMConventionsChecker before changing the behavior in AnalysisConsumer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96183 91177308-0d34-0410-b5e6-96231b3b80d8
