2010-01-19Rework the CXSourceLocation and CXSourceRange APIs. They are nowDouglas Gregor
opaque data structures accessed through the new functions clang_getInstantiationLocation(), clang_getRangeStart(), and clang_getRangeEnd(). The new API permits later extensions to introduce new functions to allow CIndex clients to walk macro instantiations, if we ever care. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93915 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Eliminate cursor kinds used to express definitions. Instead, provideDouglas Gregor
CIndex functions that (1) map from a reference or declaration to the corresponding definition, if available, and (2) determine whether a given declaration cursor is also a definition. This eliminates a lot of duplication in the cursor kinds, and maps more closely to the Clang ASTs. This is another API + ABI breaker with no deprecation. Yay, progress. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93893 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Introduce clang_getCursorReferenced, to get a cursor pointing at theDouglas Gregor
entity that a particular cursor references. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93830 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Implement clang_getCursorExtent, which provides a source range for theDouglas Gregor
cursor itself. In particular, for references this returns the source range of the reference rather than the source range of the thing it refers to. Switch c-index-test from clang_getDeclExtent (which will eventually be deprecated and removed) over to clang_getCursorExtent. The source ranges we print for references now make sense; fix up the tests appropriately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93823 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-18Now that a reasonable deprecation cycle has passed, killDouglas Gregor
clang_getCursorLine(), clang_getCursorColumn(), clang_getCursorSource(), and clang_getCursorSourceFile() outright. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93801 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-18Introduce clang_getCursorLocation(), which supercedesDouglas Gregor
clang_getCursorLine(), clang_getCursorColumn(), clang_getCursorSource(), and clang_getCursorSourceFile(). Mark those 4 functions as deprecated and stop using them ourselves. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93800 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-18Clean up the CIndex API slightly.Douglas Gregor
Renamed CXSourceFileLine to CXSourceLocation and added a CXFile, to better match Clang's SourceLocation. Teach clang_getDeclExtent to fill in the CXFile properly. Renamed CXSourceExtent to CXSourceRange, to better match Clang's SourceLocation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93783 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-18Replace clang_getDeclUSR() with clang_getCursorUSR(). Also remove printing ↵Ted Kremenek
'contexts' from c-index-test output; it wasn't helpful and was extremely brittle. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93760 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-16Remove 'default' case in switch statement in clang_getCursorKindSpelling(). ↵Ted Kremenek
This identified a missing case (warned by the compiler) and identified that CXCursor_FirstDecl didn't actually correspond to the first decl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93622 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-13Add 'referringDecl' field to CXCursor to prepare the way to better model ↵Ted Kremenek
declaration references from other delcarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93343 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-12Rename clang_getUSR() -> clang_getDeclUSR(). For now we take a CXDecl ↵Ted Kremenek
instead of a CXEntity. Enhance USR generation a bit with support for records. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93267 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-12Change clang_getUSR() to return a CXString instead of a 'const char *'.Ted Kremenek

2010-01-11CIndex:Ted Kremenek
- Remove unused (and unimplemented) clang_getDeclarationName(). - Remove unused (and unimplemented) clang_getEntity(). - Add clang_getEntityFromDecl(): maps from a CXDecl to a CXEntity) - Add clang_getDeclaration(): maps from a (CXEntity, CXTranslationUnit) to a CXDecl). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93209 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-10Improve code completion by introducing patterns for the various C andDouglas Gregor
C++ grammatical constructs that show up in top-level (namespace-level) declarations, member declarations, template declarations, statements, expressions, conditions, etc. For example, we now provide a pattern for static_cast<type>(expr) when we can have an expression, or using namespace identifier; when we can have a using directive. Also, improves the results of code completion at the beginning of a top-level declaration. Previously, we would see value names (function names, global variables, etc.); now we see types, namespace names, etc., but no values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93134 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-08For now, add back clang_getDeclSource().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93003 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-06Change clang_getDeclExtent() to have the endpoint point to the last ↵Ted Kremenek
character in the last token. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92869 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-06Add missing CINDEX_LINKAGE.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92827 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-05Remove deprecated function 'clang_getDeclSource()'. Use ↵Ted Kremenek
'clang_getDeclFile()' instead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92803 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-05Add C API hook 'clang_getDeclExtent()', which returns the source extent of a ↵Ted Kremenek
declaration. This implements <rdar://problem/7280072>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92802 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-05Split (mostly nonexistent) USR code out from the main CIndex logic.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92789 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-18Extend code-completion results with the type of each resultDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91702 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-18Change clang_codeComplete API to return the results in a structure onDouglas Gregor
the heap, so that clients are not forced to copy the results during the initial iteration. A separate clang_disposeCodeCompleteResults function frees the returned results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91690 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-17Include <time.h> in order to use 'time_t'.Chandler Carruth
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91597 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03Switch clang_createTranslationUnitFromSourceFile to use ↵Daniel Dunbar
ASTUnit::LoadFromCommandLine. - This is much faster, as it avoids the overhead of dumping an AST file to disk and reloading it. - For debugging purposes, there is a clang_setUseExternalASTGeneration hook which can be used to disable this. On the Sketch Cocoa app, the speedup is pretty nice, especially when using a PCH file while scanning the source: Wall time to c-index-test all files (no PCH): Old: 23.4221 New: 12.3884 Wall time to c-index-test all files (with a PCH, and "local" mode): Old: 10.9233 New: 1.9038 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90385 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Extend the CIndex code-completion API to perform code completionDouglas Gregor
involving unsaved files, using the -remap-file= functionality recently added to clang-cc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90314 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-17Add clang_getNullCursor() and clang_equalCursors() (the latter for comparing ↵Ted Kremenek
cursors). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89131 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-17Allow "source_filename" to be an optional argument (the client can provide ↵Ted Kremenek
NULL). This allows the client to put the source_filename in the command_line_args without fear of the file being named twice. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89118 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Introduce CXString type and associated functions clang_getCString() and ↵Steve Naroff
clang_disposeString(). This abstraction will help us manage string memory for complex names that cross the C++/C boundary (e.g. ObjC methods, selectors). This patch also uses it in clang_getTranslationUnitSpelling (which I'm not sure is necessary). Will investigate later...since the extra malloc() can't hurt (for now). Patch by John Thompson. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86562 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-07Various improvements to Clang's code-completion infrastructure:Douglas Gregor
- Introduce more code-completion string "chunk" kinds that describe symbols, the actual text that the user is expected to type, etc. - Make the generation of macro results optional, since it can be slow - Make code-completion accessible through the C API, marshalling the code-completion results through a temporary file (ick) to maintain process separation. The last doesn't have tests yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86306 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-31Add two missing CINDEX_LINKAGE uses, in libCIndex, from KovarththananDouglas Gregor
Rajaratnam! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85665 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28Remove _clang_initCXLookupHint() and _clang_getCursorWithHint(). Related to ↵Steve Naroff
<rdar://problem/7310688>. Localize the optimization to ResolveLocationInAST(). The last valid AST location is now stored with ASTUnit. There still isn't optimal, however it's an improvement (with a much cleaner API). Having the client manage an "hint" is error prone and complex. I wanted to land the major changes before finishing up the optimizations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85425 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27Add support for 'CXFile' (<rdar://problem/7303360>).Steve Naroff
- 4 new functions (clang_getCursorSourceFile, clang_getDeclSourceFile, clang_getFileName, clang_getFileTime). - Should remove clang_getDeclSource() and clang_getCursorSource(). For now, just put 'deprecate' comment in header. - Also changed CXX style comment to C style (to eliminate warning). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85238 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84873 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22Enhance 'clang_createTranslationUnitFromSourceFile()' in two ways:Ted Kremenek
(1) Allow the source file to be specified in the actual command line arguments by allowing the caller to set 'source_filename' to NULL. (2) Automatically strip off the arguments '-emit-ast', '-fsyntax-only', and '-c'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84802 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-21Extend clang_getCursor() to take a 'relativeDecl' argument (so speed up ↵Steve Naroff
searching). Without a 'relativeDecl', the algorithm is n-squared. For example, running the following command on 'Large.m' takes hours without a 'relatvieDecl'. snaroff% time ../../Debug/bin/c-index-test Large.ast all > Large.out snaroff% cat Large.m #import <Cocoa/Cocoa.h> #import <QuickTime/QuickTime.h> #import <OpenGL/OpenGL.h> With a 'relativeDecl', it takes <30 seconds:-) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84760 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-20Add an example to help claify the process/assumptions...Steve Naroff
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84642 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-20- Extend clang_createIndex() to support PCH and diagnostic 'filtering'. This ↵Steve Naroff
seems cleaner to me without sacrificing much flexibility. - Remove clang_wantOnlyLocalDeclarations(). - Remove 'displayDiagnostics' arguments to clang_createTranslationUnitFromSourceFile() and clang_createTranslationUnit(). - Have clang_createTranslationUnitFromSourceFile() strip the '-o <outfile>' command line arguments if they exist. Document this semantic in the header. Also verify we have a valid ASTUnit before telling it to 'unlinkTemporaryFile()'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84634 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-19Really fix <rdar://problem/7312058> by adding a 'displayDiagnostics' option toTed Kremenek
clang_createTranslationUnit() and clang_createTranslationUnitFromSourceFile(). The user can now specify if the diagnostics from Clang are printed to stderr or are silenced completely. We can obviously evolve this API to be more general in the future. Note: Added a FIXME since I wasn't certain what was the best way to redirect to something analogous to '/dev/null' on Windows. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84548 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Keep track of whether declararions were loaded from a precompiledDouglas Gregor
header or not via a new "PCHLevel" field in Decl. We currently use this information to help CIndex filter out declarations that came from a precompiled header (rather than from an AST file). Further down the road, it can be used to help implement multi-level precompiled headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84267 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15Implement <rdar://problem/7303432> [Clang/Index] In-memory-style AST ↵Steve Naroff
