2009-04-22Remove the serialization code that predates precompiledDouglas Gregor
headers. Future approaches to (de-)serializing ASTs will be based on the PCH infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69828 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-15For source location entries that describe instantiations, encode theDouglas Gregor
token length in the PCH file rather than trying (and failing) to reconstruct it be getting the spelling token's length. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69191 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Include the SourceManager's line table in the PCH file. We can nowDouglas Gregor
properly cope with #line directives in PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68963 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10PCH serialization/deserialization of the source manager. With thisDouglas Gregor
improvement, source locations read from the PCH file will properly resolve to the source files that were used to build the PCH file itself. Once we have the preprocessor state stored in the PCH file, source locations that refer to macro instantiations that occur in the PCH file should have the appropriate instantiation information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68758 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64606 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-15track "just a little more" location information for macro instantiations.Chris Lattner
Now instead of just tracking the expansion history, also track the full range of the macro that got replaced. For object-like macros, this doesn't change anything. For _Pragma and function-like macros, this means we track the locations of the ')'. This is required for PR3579 because apparently GCC uses the line of the ')' of a function-like macro as the location to expand __LINE__ to. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64601 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-04lower the interface to getLineNumber like we did forChris Lattner
getColumnNumber. This fixes a FIXME in SourceManager::getPresumedLoc because we now just decompose the sloc once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63701 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04make SM::getColumnNumber take a predecomposed FileID/offset, whichChris Lattner
makes it clear to clients that they have to pick an instantiation or spelling location before calling it and allows optimization based on that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63698 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03more plumbing for #line propagation. Use happy bit #3 Chris Lattner
out of FileInfo :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63672 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-03reclaim my precious bit in FileInfo by ensuring that ContentCache objectsChris Lattner
are 8-byte aligned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63630 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03switch SourceManager from using an std::map and std::list of Chris Lattner
ContentCache objects to using a densemap and list, and allocating the ContentCache objects from a bump pointer. This does not speed up or slow down things substantially, but gives us control over their alignment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63628 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03Content Cache only needs to be 4-byte aligned. Since it is stored inChris Lattner
an std::set, we can't make a strong guarantee about what its alignment will be. Since I don't need the 3rd bit anyway yet, just change the assertion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63588 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Introduce a new PresumedLoc class to represent the concept of a locationChris Lattner
as reported to the user and as manipulated by #line. This is what __FILE__, __INCLUDE_LEVEL__, diagnostics and other things should follow (but not dependency generation!). This patch also includes several cleanups along the way: - SourceLocation now has a dump method, and several other places that did similar things now use it. - I cleaned up some code in AnalysisConsumer, but it should probably be simplified further now that NamedDecl is better. - TextDiagnosticPrinter is now simplified and cleaned up a bit. This patch is a prerequisite for #line, but does not actually provide any #line functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63098 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-26make getInstantiationLoc and getSpellingLoc handle multiply instantiatedChris Lattner
locations, and move the slow case out of line. No perf change on cocoa.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63033 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26make sure we have a definition of uintptr_t.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63019 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26start plumbing together the line table information. So far we justChris Lattner
unique the Filenames in #line directives, assigning them UIDs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63010 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Bitmangle file characteristic bits into the low bits of Chris Lattner
the content cache pointer. This saves 105876 bytes on cocoa.h because it shrinks the SLocEntry union, which we have a big array of. It would be nice to use PointerIntPair here, but we can't because it is in a union. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63004 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Check in the long promised SourceLocation rewrite. This lays theChris Lattner
ground work for implementing #line, and fixes the "out of macro ID's" problem. There is nothing particularly tricky about the code, other than the very performance sensitive SourceManager::getFileID() method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62978 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19rearrange SourceManager methods to group them by kind. Remove theChris Lattner
SourceManager::getFileCharacteristic(FileID) method: we need a full location to know if it is a system header etc in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62503 91177308-0d34-0410-b5e6-96231b3b80d8
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

2009-01-19SourceManager::getBufferData(SourceLocation) is dead, delete it.Chris Lattner

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

2009-01-16Change 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

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

2008-09-26Fix 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
