2011-09-19In libclang, when visiting preprocessed entities in a source range, useArgyrios Kyrtzidis
PreprocessingRecord's getPreprocessedEntitiesInRange. Also remove all the stuff that were added in ASTUnit that are unnecessary now that we do a binary search for preprocessed entities and deserialize only what is necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140063 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19Introduce PreprocessingRecord::getPreprocessedEntitiesInRange()Argyrios Kyrtzidis
which will do a binary search and return a pair of iterators for preprocessed entities in the given source range. Source ranges of preprocessed entities are stored twice currently in the PCH/Module file but this will be fixed in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140058 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-17With modules, we can end up loading a new module after we've seen anDouglas Gregor
arbitrary amount of code. This forces us to stage the AST writer more strictly, ensuring that we don't assign a declaration ID to a declaration until after we're certain that no more modules will get loaded. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139974 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15[PCH] Overhaul how preprocessed entities are [de]serialized.Argyrios Kyrtzidis
-Use an array of offsets for all preprocessed entities -Get rid of the separate array of offsets for just macro definitions; for references to macro definitions use an index inside the preprocessed entities array. -Deserialize each preprocessed entity lazily, at first request; not in bulk. Paves the way for binary searching of preprocessed entities that will offer efficiency and will simplify things on the libclang side a lot. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139809 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Switch the serialization of LangOptions over to use the .def file. WeDouglas Gregor
should no longer have the serialization of LangOptions out of sync with the structure itself (yay). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139613 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Switch LangOptions over to a .def file that describes header of theDouglas Gregor
language options. Use that .def file to declare the LangOptions class and initialize all of its members, eliminating a source of annoying initialization bugs. AST serialization changes are next up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139605 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-09Introduce a new predicate Decl::isFromASTFile() to determine whether aDouglas Gregor
declaration was deserialized from an AST file. Use this instead of Decl::getPCHLevel() wherever possible. This is a simple step toward killing off Decl::getPCHLevel(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139427 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-08[libclang] Fix annotation and getting a "macro expansion" cursorArgyrios Kyrtzidis
for a builtin macro expansion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139298 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-08Implement the Objective-C 'instancetype' type, which is an alias ofDouglas Gregor
'id' that can be used (only!) via a contextual keyword as the result type of an Objective-C message send. 'instancetype' then gives the method a related result type, which we have already been inferring for a variety of methods (new, alloc, init, self, retain). Addresses <rdar://problem/9267640>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139275 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-06Finish implementing (de-)serialization of the CXXDefinitionData bitsDouglas Gregor
needed for implicit move constructors and move assignment operators. Fixes PR10847. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139144 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Modules hide macro definitions by default, so that silly things likeDouglas Gregor
include guards don't show up as macro definitions in every translation unit that imports a module. Macro definitions can, however, be exported with the intentionally-ugly #__export_macro__ directive. Implement this feature by not even bothering to serialize non-exported macros to a module, because clients of that module need not (should not) know that these macros even exist. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138943 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Support importing of ObjC categories from modules.Argyrios Kyrtzidis
The initial incentive was to fix a crash when PCH chaining categories to an interface, but the fix was done in the "modules way" that I hear is popular with the kids these days. Each module stores the local chain of categories and we combine them when the interface is loaded. We also warn if non-dependent modules introduce duplicate named categories. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138926 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-30When writing out the entries in a lookup table for a DeclContext, makeDouglas Gregor
sure that all of the CXXConversionDecls go into the same bucket. Otherwise, name lookup might not find them all. Fixes <rdar://problem/10041960>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138824 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-30In ASTWriter::WriteDeclContextVisibleBlock, don't write empty lookups.Argyrios Kyrtzidis
Empty lookups can occur in the DeclContext map when we are chaining PCHs, where the empty lookup indicates that we already looked in ExternalASTSource. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138816 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-24Don't force the complete deserialization of the visible-declarationsDouglas Gregor
table when serializing an AST file. This was a holdover from the days before chained PCH, and is a complete waste of time and storage now. It's a good thing it's useless, because I have no idea how I would have implemented MaterializeVisibleDecls efficiently in the presence of modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138496 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-21Boost the efficiency of SourceManager::getMacroArgExpandedLocation.Argyrios Kyrtzidis
Currently getMacroArgExpandedLocation is very inefficient and for the case of a location pointing at the main file it will end up checking almost all of the SLocEntries. Make it faster: -Use a map of macro argument chunks to their expanded source location. The map is for a single source file, it's stored in the file's ContentCache and lazily computed, like the source lines cache. -In SLocEntry's FileInfo add an 'unsigned NumCreatedFIDs' field that keeps track of the number of FileIDs (files and macros) that were created during preprocessing of that particular file SLocEntry. This is useful when computing the macro argument map in skipping included files while scanning for macro arg FileIDs that lexed from a specific source file. Due to padding, the new field does not increase the size of SLocEntry. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138225 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-18Keep track of which modules have been loaded directly (e.g., viaDouglas Gregor
-import-module) vs. loaded because some other module depends on them. As part of doing this, pass down the module that caused a module to be loaded directly, rather than assuming that we're loading a chain. Finally, write out all of the directly-loaded modules when serializing an AST file (using the new IMPORTS record), so that an AST file can depend on more than one other AST file, all of which will be loaded when that AST file is loaded. This allows us to form and load a tree of modules, but we can't yet load a DAG of modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137923 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-17In the AST file format, eliminate the CHAINED_METADATA record. Instead,Douglas Gregor
all AST files have a normal METADATA record that has the same form regardless of whether we refer to a chained PCH or any other kind of AST file. Introduce the IMPORTS record, which describes all of the AST files that are imported by this AST file, and how (as a module, a PCH file, etc.). Currently, we emit at most one entry to this record, to support chained PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137869 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-17[PCH] When writing out ExpansionInfo, make sure we don't lose track if it's ↵Argyrios Kyrtzidis
a macro arg expansion or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137792 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Switch the __int128_t and __uint128_t types over to predefined typesDouglas Gregor
in the AST format, which are built lazily by the ASTContext when requested. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137437 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Switch the Objective-C 'SEL' type over to a predefined type in theDouglas Gregor
AST file format, lazily generating the actual declaration in ASTContext as needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137434 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Switch the Objective-C 'Class' type over to a predefined type in theDouglas Gregor
AST file format, lazily generating the actual declaration in ASTContext as needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137431 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Move the creation of the predefined typedef for Objective-C's 'id'Douglas Gregor
type over into the AST context, then make that declaration a predefined declaration in the AST format. This ensures that different AST files will at least agree on the (global) declaration ID for 'id', and eliminates one of the "special" types in the AST file format. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137429 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Collapse ASTWriter::WriteASTChain into ASTWriter::WriteASTCore,Douglas Gregor
eliminating a pile of redundant code (and probably some bugs in the process). The variation between chained and non-chained PCH is fairly small now anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137410 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12In the serialized AST format, make the translation unit a "predefined"Douglas Gregor
declaration that never actually gets serialized. Instead, serialize the various kinds of update records (lexical decls, visible decls, the addition of an anonymous namespace) for the translation unit, even if we're not chaining. This way, we won't have to deal with multiple loaded translation unit declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137395 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-09Move the creation of the record type for the state of Objective-C fastDouglas Gregor
enumerations from the ASTContext into CodeGen, so that we don't need to serialize it to AST files. This appears to be the last of the low-hanging fruit for SpecialTypes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137124 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Don't serialize the block descriptor or block extended descriptorDouglas Gregor
types to AST files; they're only used by debug info generation anyway, and shouldn't ever exist in the AST anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137122 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Move the construction of the RecordDecl representing the runtimeDouglas Gregor
layout of a constant NSString from the ASTContext over to CodeGen, since this is solely CodeGen's responsibility. Eliminates one of the unnecessary "special" types that we serialize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137121 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-04Introduce local -> global mapping for preprocessed entity IDs. This isDouglas Gregor
the last of the ID/offset/index mappings that I know of. Unfortunately, the "gap" method of testing doesn't work here due to the way the preprocessing record performs iteration. We'll do more testing once multi-AST loading is possible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136902 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-04In the AST reader and writer, slide the preprocessed entity IDs by +1Douglas Gregor
