2010-03-19Visit preprocessing elements (macro instantiations and macroDouglas Gregor
definitions) as part of the translation unit, so that normal visitation, token-annotation, and cursor-at retrieval all see preprocessing elements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98907 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-18Explicitly link macro instantiations to macro definitions in theDouglas Gregor
preprocessing record. Use that link with clang_getCursorReferenced() and clang_getCursorDefinition() to match instantiations of a macro to the definition of the macro. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98842 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-18Expose macro definitions as CIndex cursors. These can still only beDouglas Gregor
generated by clang_annotateTokens(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98837 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
2010-03-18More token-annotation experimentation, preprocessing the annotatedDouglas Gregor
token sequence to detect macro instantiations (that produce at least token). WIP. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98826 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-18Experimental stab at using relexing to identify preprocessorDouglas Gregor
directives while annotating tokens in CIndex. This functionality should probably be factored out of this routine, but we're not there yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98786 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-16Give SourceManager a Diagnostic object with which to report errors,Douglas Gregor
and start simplifying the interfaces in SourceManager that can fail. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98594 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-15Introduce a new BufferResult class to act as the return type ofDouglas Gregor
SourceManager's getBuffer() (and similar) operations. This abstract can be used to force callers to cope with errors in getBuffer(), such as missing files and changed files. Fix a bunch of callers to use the new interface. Add some very basic checks for file consistency (file size, modification time) into ContentCache::getBuffer(), although these checks don't help much until we've updated the main callers (e.g., SourceManager::getSpelling()). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98585 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-05Check if 'Unit' is NULL before trying to iterate over the diagnostics.Ted Kremenek
This obviates a null dereference that can occur when 'NumErrors' is not zero. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97849 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-27When given unsaved files in clang_createTranslationUnitFromSourceFile,Douglas Gregor
copy the source buffers provided rather than referencing them directly, so that the caller can free those buffers immediately after calling clang_createTranslationUnitFromSourceFile(). Otherwise, we risk hitting those buffers later (when building source ranges, forming diagnostics, etc.). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97296 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Frontend: Pull CodeGenAction out more, and eliminate CreateBackendConsumer.Daniel Dunbar
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. This also isolates the surface area in clang which depends on LLVM CodeGen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97110 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-21Attempt to fix the MSVC9 failure with c-indext-test, where the CIndex DLLDouglas Gregor
and the c-index-test executable end up getting different copies of stderr, causing non-deterministic ordering of output. Fixed by flushing the file after printing a diagnostic (only on Windows). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96754 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-18Introduce CIndex API functions for displaying a diagnostic, with someDouglas Gregor
knobs to control formatting. Eventually, I'd like to merge the implementation of this code with the TextDiagnosticPrinter, so that it's easy for CIndex clients to produce beautiful diagnostics like the clang compiler does.
