2013-01-07[libclang] When annotating preprocessor tokens, if we are in a macro definition,Argyrios Kyrtzidis
check if the token was ever a macro name and annotate it if that's the case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171776 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-07[libclang] Simplify annotation of preprocessing tokens and remove the ↵Argyrios Kyrtzidis
AnnotateTokensData DenseMap and the lookups associated with it. Instead of lexing for preprocessor tokens, associating the annotation with the location in a map, and later lookup in the map in order to adjust the cursor annotation, just annotate the cursor while lexing for preprocessor tokens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171775 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-12[libclang] Make sure tokens from preprocessor directives are annotated as such,Argyrios Kyrtzidis
even if the directive is inside a declaration. Fixes rdar://11548788 & http://llvm.org/PR12970 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169949 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-21For SourceManager::isBeforeInTranslationUnit(), have it consider macro arg ↵Argyrios Kyrtzidis
expanded token locations as coming before the closing ')' of a function macro expansion. Include a unit test for SourceManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147056 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-05Expose more statement, expression, and declaration kinds in libclang,Douglas Gregor
from Manuel Holtgrewe! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141200 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-26Don't map a file:line:col triplet that is inside the preamble range toArgyrios Kyrtzidis
a "loaded" location of the precompiled preamble. Instead, handle specially locations of preprocessed entities: -When looking up for preprocessed entities, map main file locations inside the preamble range to a preamble loaded location. -When getting the source range of a preprocessing cursor, map preamble loaded locations back to main file locations. Fixes rdar://10175093 & http://llvm.org/PR10999 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140519 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19For SourceManager::isBeforeInTranslationUnit, a location pointingArgyrios Kyrtzidis
inside a macro argument should be regarded as coming before the location of the expanded tokens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140053 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-18[libclang] Annotate correctly macro argument tokens.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137961 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Update all of the libclang code corresponding to the preprocessorChandler Carruth
MacroInstantiation -> MacroExpansion rename. Internally, everything is switched. Introduce a new cursor kind enum with the new name, but retain the old name as an alias so that we don't break backwards compatibility. Also update the debug printing routine to use 'macro expansions' as its explicitly not guaranteed to be stable, and mechanically switch the test cases over to that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135140 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-04Introduce a new libclang API, clang_isFileMultipleIncludeGuarded(),Douglas Gregor
which determines whether a particular file is actually a header that is intended to be guarded from multiple inclusions within the same translation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130808 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09ntroduce clang_getSpellingLocation() into libclang, to provide theDouglas Gregor
location where we're spelling a token even within a macro. clang_getInstantiationLocation() tells where we instantiated the macro. I'm still not thrilled with the CXSourceLocation/CXSourceRange APIs, since they gloss over macro-instantiation information. Take 2: this time, adjusted tests appropriately and used a "simple" approach to the spelling location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118495 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Improve the implementation of libclang's token-annotation logic forDouglas Gregor
entities in the preprocessing record. Previously, we would only end up getting the first token of a preprocessing record annotated correctly. For example, given #include "foo.h" we would only get the '#' annotated as an inclusion directive; the 'include' and '"foo.h"' tokens would be given the general 'processing directive' annotation. Now, we get proper annotations for entities in the preprocessing record. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117001 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-20Extend the preprocessing record and libclang with support forDouglas Gregor
inclusion directives, keeping track of every #include, #import, etc. in the translation unit. We keep track of the source location and kind of the inclusion, how the file name was spelled, and the underlying file to which the inclusion resolved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116952 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-14Always recurse into sub-cursors when annotating tokens, as this information ↵Ted Kremenek
is used for annotating macro arguments. This finishes up <rdar://problem/8044584>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111066 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-14As a heuristic, annotate tokens (via clang_annotateTokens) that are the ↵Ted Kremenek
arguments of a macro instantiation using the closest cursor with the same spelling location. Because macro arguments can get token pasted in any arbitrary order, we use the annotation map to paper over the token -> cursor annotations during our post-processing stage. This fixes most of <rdar://problem/8044584>, but still doesn't work for assert(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111062 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
