2009-01-19Rename SourceManager::getCanonicalFileID -> getFileID. There isChris Lattner
no longer such thing as a non-canonical FileID. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62499 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19remove the public SourceManager::getContentCacheForLoc method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62497 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19remove the SourceManager:: and FullSourceLoc::getFileEntryForLoc methods.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62496 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19SourceManager::getBufferData(SourceLocation) is dead, delete it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62495 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19some minor cleanups to SourceManager, and eliminate the Chris Lattner
SourceManager::getBuffer(SourceLocation) method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62494 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19Make SourceLocation::getFileLoc private to reduce the API exposure of Chris Lattner
SourceLocation. This requires making some cleanups to token pasting and _Pragma expansion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62490 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17Rename SourceLocation::getFileID to getChunkID, because it returnsChris Lattner
the chunk ID not the file ID. This exposes problems in TextDiagnosticPrinter where it should have been using the canonical file ID but wasn't. Fix these along the way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62427 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17this massive patch introduces a simple new abstraction: it makesChris Lattner
"FileID" a concept that is now enforced by the compiler's type checker instead of yet-another-random-unsigned floating around. This is an important distinction from the "FileID" currently tracked by SourceLocation. *That* FileID may refer to the start of a file or to a chunk within it. The new FileID *only* refers to the file (and its #include stack and eventually #line data), it cannot refer to a chunk. FileID is a completely opaque datatype to all clients, only SourceManager is allowed to poke and prod it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62407 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17make "ContentCache::Buffer" mutable to avoid a const_cast.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62403 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17Instead of iterating over FileID's, have PTH generation iterate over theChris Lattner
content cache directly. Content cache has a 1-1 mapping with fileentries, whereas multiple FileIDs can be the same FileEntry. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62401 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-16more SourceLocation lexicon change: instead of referring to theChris Lattner
"logical" location, refer to the "instantiation" location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62316 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-16rename "virtual location" of a macro to "instantiation location".Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62315 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-16Change some terminology in SourceLocation: instead of referring to Chris Lattner
the "physical" location of tokens, refer to the "spelling" location. This is more concrete and useful, tokens aren't really physical objects! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62309 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-06Oops. Un-publicify SrcMgr::ContentCache::Buffer.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61790 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-06Add QualifiedDeclRefExpr, which retains additional source-locationDouglas Gregor
information for declarations that were referenced via a qualified-id, e.g., N::C::value. We keep track of the location of the start of the nested-name-specifier. Note that the difference between QualifiedDeclRefExpr and DeclRefExpr does have an effect on the semantics of function calls in two ways: 1) The use of a qualified-id instead of an unqualified-id suppresses argument-dependent lookup 2) If the name refers to a virtual function, the qualified-id version will call the function determined statically while the unqualified-id version will call the function determined dynamically (by looking up the appropriate function in the vtable). Neither of these features is implemented yet, but we do print out qualified names for QualifiedDeclRefExprs as part of the AST printing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61789 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-06Misc changes to SourceManager::ContentCache:Ted Kremenek
- 'Buffer' is now private and must be accessed via 'getBuffer()'. This paves the way for lazily mapping in source files on demand. - Added 'getSize()' (which gets the size of the content without necessarily accessing the MemBuffer) and 'getSizeBytesMapped()'. - Modifed SourceManager to use these new methods. This reduces the number of places that actually access the MemBuffer object for a file to those that actually look at the character data. These changes result in no performance change for -fsyntax-only on Cocoa.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61782 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Add version of 'getFileCharacteristic()' for FileIDs.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59669 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18SourceManager::getLineNumber is logically const except for caching.Chris Lattner
Use mutable to make it so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59498 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27Rename Characteristic_t to CharacteristicKindChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58224 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-21Add fileid_iterator to SourceManager.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57878 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-26clean up a bunch of fixme's I added, by moving Chris Lattner
DirectoryLookup::DirType into SourceManager.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56692 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-26Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfoChris Lattner
to whether the fileid is a 'extern c system header' in addition to whether it is a system header, most of this is spreading plumbing around. Once we have that, PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to base the system header state on FileIDInfo instead of HeaderSearch. Finally, in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness of a file being entered can be set due to the #includer or the #includee. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56688 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-29minor cleanupNico Weber
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55538 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-10* Remove isInSystemHeader() from DiagClient, move it to SourceManagerNico Weber
* Move FormatError() from TextDiagnostic up to DiagClient, remove now empty class TextDiagnostic * Make DiagClient optional for Diagnostic This fixes the following problems: * -html-diags (and probably others) does now output the same set of warnings as console clang does * nothing crashes if one forgets to call setHeaderSearch() on TextDiagnostic * some code duplication is removed git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54620 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-09add assert, use make_pair() instead of pair constructorNico Weber
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54596 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-26Another class -> struct in declaration to match definition.Cedric Venet
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52782 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-06Use a common SourceManager when processing multiple files. This allows us ↵Ted Kremenek
to cache the contents of source files already loaded from disk. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52066 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Added "getCanonicalID()", "isFromSameFile", and "isFromMainFile" to compareTed Kremenek
the files of different SourceLocations. These methods correctly handle the case where a file may have multiple FileIDs due to it being large enough to be spread across several chunks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49682 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-08Make SourceManager::getFullFilePos() public.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49402 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-02Cleanup previous patch (based on feedback from Ted).Steve Naroff
Since this behavior is useful for most classes, we might consider adding a simple 3 method class that implements the behavior. Ted said that Boost has such a class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46654 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-01Make sure SourceManager/HeaderSearch don't support default copy constructors ↵Steve Naroff
(since they result in bad runtime behavior). I'm sure there are other classes that might need this "guard", however I was bitten by these 2 recently (so I thought I'd fix them). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46653 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29Don't attribute in file headers anymore. See llvmdev for theChris Lattner
discussion of this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45410 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-20Fix trivial self-infinite-recursionChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45248 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-20Added method getFileEntryForID() to SourceManager.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45237 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-19Added methods createMainFileID() and createMainFileIDForMemBuffer() toTed Kremenek
SourceManager to allow SourceManager to directly intern the MainFileID when it is created. Removed setMainFileID(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45231 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-19Added storage of the FileID of the the main source file of a translation unitTed Kremenek
in SourceManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45225 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-05Renamed SourceManager::Read to SourceManager::CreateAndRegister.Ted Kremenek
Now sourcemanager deserializer automatically self-registers itself with the deserializer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44591 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-05Implemented initial serialization support for SourceManager.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44590 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-04Implemented serialization of SrcMgr::ContentCache.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44578 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-04Fixed a few more comments to change "FileInfo" to "ContentCache."Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44574 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-09rename getInstantiationLoc to match the scheme of isPhysicalLoc.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43969 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-09change source location to have two bits for macros, trackingChris Lattner
whether the location is the start and/or end of an expansion. These are currently not set or used by anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43968 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-30Updated some comments.Ted Kremenek
Disabled assignments for ContentCache. Copy-ctor for ContentCache now has an assertion preventing it to be copied from an object that already has an allocated buffer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43526 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-30Removed SrcMgr::FileInfo and SrcMgr::InfoRec and replaced them with aTed Kremenek
single class: ContentCache. This simplifies the logic in SourceManager and makes the ownership of MemoryBuffers clearer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43518 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-30update some comments.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43506 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-12add a new SM::getDecomposedFileLoc method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42931 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-11Push the rewriting APIs along. Build a trivial client that replaces tabsChris Lattner
with x's for now. The APIs are all unimplemented, so it doesn't do anything yet! :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42868 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-30constify a method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41600 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-24Use a smallstring instead of an std::string in FileChanged to avoid some ↵Chris Lattner
malloc traffic. This speeds up -E on xalancbmk by 2.4% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40461 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-24Add a cache to SourceManager to accellerate line # lookup. This is aChris Lattner
bottleneck for -E computation, because every token that starts a line needs to determine *which* line it is on (so -E mode can insert the appropriate vertical whitespace). This optimization improves this common case where it is striding through the line # table. This speeds up -E on xalancbmk by 3.2% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40459 91177308-0d34-0410-b5e6-96231b3b80d8
