| | | | | | | | | | | | | | | of its categories because it is going to be rewritten (and the chain will be serialized again), otherwise we may form a cycle in its categories list when deserializing. Also introduce ASTMutationListener::CompletedObjCForwardRef to notify that a forward reference was completed; using Decl's isChangedSinceDeserialization/setChangedSinceDeserialization is bug inducing and kinda gross, we should phase it out. Fixes infinite loop in rdar://10418538. llvm-svn: 144465

| | | | | | | | | that it retains source location information for the type. Aside from general goodness (being able to walk the types described in that information), we now have a proper representation for dependent delegating constructors. Fixes PR10457 (for real). llvm-svn: 143410

* [PCH] Keep track of file-level declarations that are contained by files.Argyrios Kyrtzidis2011-10-281-43/+127
| | | | | | | | | | | | Introduce a FILE_SORTED_DECLS [de]serialization record that contains a file sorted array of file-level DeclIDs in a PCH/Module. The rationale is to allow "targeted" deserialization of decls inside a range of a source file. Cocoa PCH increased by 0.8% Difference of creation time for Cocoa PCH is below the noise level. llvm-svn: 143238
* Make the loading of information attached to an IdentifierInfo from anDouglas Gregor2011-10-271-18/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AST file more lazy, so that we don't eagerly load that information for all known identifiers each time a new AST file is loaded. The eager reloading made some sense in the context of precompiled headers, since very few identifiers were defined before PCH load time. With modules, however, a huge amount of code can get parsed before we see an @import, so laziness becomes important here. The approach taken to make this information lazy is fairly simple: when we load a new AST file, we mark all of the existing identifiers as being out-of-date. Whenever we want to access information that may come from an AST (e.g., whether the identifier has a macro definition, or what top-level declarations have that name), we check the out-of-date bit and, if it's set, ask the AST reader to update the IdentifierInfo from the AST files. The update is a merge, and we now take care to merge declarations before/after imports with declarations from multiple imports. The results of this optimization are fairly dramatic. On a small application that brings in 14 non-trivial modules, this takes modules from being > 3x slower than a "perfect" PCH file down to 30% slower for a full rebuild. A partial rebuild (where the PCH file or modules can be re-used) is down to 7% slower. Making the PCH file just a little imperfect (e.g., adding two smallish modules used by a bunch of .m files that aren't in the PCH file) tips the scales in favor of the modules approach, with 24% faster partial rebuilds. This is just a first step; the lazy scheme could possibly be improved by adding versioning, so we don't search into modules we already searched. Moreover, we'll need similar lazy schemes for all of the other lookup data structures, such as DeclContexts. llvm-svn: 143100

* With modules, we can end up loading a new module after we've seen anDouglas Gregor2011-09-171-7/+69

* [PCH] Overhaul how preprocessed entities are [de]serialized.Argyrios Kyrtzidis2011-09-151-51/+23
| | | | | | | | | | | | | -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. llvm-svn: 139809

| | | | | | | | | | '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>. llvm-svn: 139275
* Finish implementing (de-)serialization of the CXXDefinitionData bitsDouglas Gregor2011-09-061-0/+4

* Extend the ASTContext constructor to delay the initialization ofDouglas Gregor2011-09-021-1/+1
| | | | | | | | 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). llvm-svn: 138985
* Modules hide macro definitions by default, so that silly things likeDouglas Gregor2011-09-011-32/+51
| | | | | | | | | | | 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. llvm-svn: 138943
* Support importing of ObjC categories from modules.Argyrios Kyrtzidis2011-09-011-0/+34
| | | | | | | | | | | | 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. llvm-svn: 138926

* Don't force the complete deserialization of the visible-declarationsDouglas Gregor2011-08-241-3/+1
| | | | | | | | | | 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. llvm-svn: 138496
* Boost the efficiency of SourceManager::getMacroArgExpandedLocation.Argyrios Kyrtzidis2011-08-211-0/+3
| | | | | | | | | | | | | | | | | | 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. llvm-svn: 138225
* Keep track of which modules have been loaded directly (e.g., viaDouglas Gregor2011-08-181-15/+20
| | | | | | | | | | | | | -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. llvm-svn: 137923
* In the AST file format, eliminate the CHAINED_METADATA record. Instead,Douglas Gregor2011-08-171-10/+22
| | | | | | | | | | | | | 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. llvm-svn: 137869
