| | | | | | | | | | | | | modules. This leaves us without an explicit syntax for importing modules in C/C++, because such a syntax needs to be discussed first. In Objective-C/Objective-C++, the @import syntax is used to import modules. Note that, under -fmodules, C/C++ programs can import modules via the #include mechanism when a module map is in place for that header. This allows us to work with modules in C/C++ without committing to a syntax. llvm-svn: 147467

* Make the loading of information attached to an IdentifierInfo from anDouglas Gregor2011-10-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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this information lazy is fairly simple: when we load a new AST file, we mark all of the existing identifiers as being out-of-date.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AST (e.g., whether the identifier has a macro definition, or what top-level declarations have that name), we check the out-of-date bit and, if it's set, ask the AST reader to update the IdentifierInfo from the AST files.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

| | | | | | | | that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. llvm-svn: 139987
* Modules hide macro definitions by default, so that silly things likeDouglas Gregor2011-09-011-0/+1
| | | | | | | | | | | 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

* Implement Objective-C Related Result Type semantics.Douglas Gregor2011-06-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Related result types apply Cocoa conventions to the type of message sends and property accesses to Objective-C methods that are known to always return objects whose type is the same as the type of the receiving class (or a subclass thereof), such as +alloc and -init. This tightens up static type safety for Objective-C, so that we now diagnose mistakes like this: t.m:4:10: warning: incompatible pointer types initializing 'NSSet *' with an expression of type 'NSArray *' [-Wincompatible-pointer-types] NSSet *array = [[NSArray alloc] init]; ^ ~~~~~~~~~~~~~~~~~~~~~~ /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:72:1: note: instance method 'init' is assumed to return an instance of its receiver type ('NSArray *') - (id)init; ^ It also means that we get decent type inference when writing code in Objective-C++0x: auto array = [[NSMutableArray alloc] initWithObjects:@"one", @"two",nil]; // ^ now infers NSMutableArray* rather than id llvm-svn: 132868
