2011-09-30Add explicit attributes to mark functions as having had theirJohn McCall
CoreFoundation object-transfer properties audited, and add a #pragma to cause them to be automatically applied to functions in a particular span of code. This has to be implemented largely in the preprocessor because of the requirement that the region be entirely contained in a single file; that's hard to impose from the parser without registering for a ton of callbacks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140846 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-17Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet
that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag.

2011-09-17When we load header file information from the external source (i.e.,Douglas Gregor
the AST reader), merge that header file information with whatever header file information we already have. Otherwise, we might forget something we already knew (e.g., that the header was #import'd already). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139979 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
2011-09-13For modules, use a hash of the compiler version, language options, andDouglas Gregor
target triple to separate modules built under different conditions. The hash is used to create a subdirectory in the module cache path where other invocations of the compiler (with the same version, language options, etc.) can find the precompiled modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139662 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-12When an import statement fails to find a module in the module cache,Douglas Gregor
but there is a corresponding umbrella header in a framework, build the module on-the-fly so it can be immediately loaded at the import statement. This is very much proof-of-concept code, with details to be fleshed out over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139558 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-12Introduce a cc1-level option to provide the path to the module cache,Douglas Gregor
where the compiler will look for module files. Eliminates the egregious hack where we looked into the header search paths for modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139538 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-08Allow C++0x enumerations with a fixed underlying type inDouglas Gregor
Objective-C. The @encode'ing of such an enumeration type is the same as its underlying type. <rdar://problem/5276348>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139297 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
2011-09-07Optimize the preprocessor's handling of the __import_module__Douglas Gregor
keyword. We now handle this keyword in HandleIdentifier, making a note for ourselves when we've seen the __import_module__ keyword so that the next lexed token can trigger a module import (if needed). This greatly simplifies Preprocessor::Lex(), and completely erases the 5.5% -Eonly slowdown Argiris noted when I originally implemented __import_module__. Big thanks to Argiris for noting that horrible regression! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139265 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-04Support code-completion for C++ inline methods and ObjC buffering methods.Argyrios Kyrtzidis
Previously we would cut off the source file buffer at the code-completion point; this impeded code-completion inside C++ inline methods and, recently, with buffering ObjC methods. Have the code-completion inserted into the source buffer so that it can be buffered along with a method body. When we actually hit the code-completion point the cut-off lexing or parsing. Fixes rdar://10056932&8319466 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139086 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-04Fix Lexer::ComputePreamble when MaxLines parameter is non-zero.Argyrios Kyrtzidis
The function was only counting lines that included tokens and not empty lines, but MaxLines (mainly initiated to the line where the code-completion point resides) is a count of overall lines (even empty ones). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139085 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Allow the preprocessor to be constructed without performing target-Douglas Gregor

2011-09-01Teach ASTContext and Preprocessor to hold on to references to the sameDouglas Gregor
LangOptions, rather than making distinct copies of LangOptions. Granted, LangOptions doesn't actually get modified, but this will eventually make it easier to construct ASTContext and Preprocessor before we know all of the LangOptions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138959 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

suppress it in system headers. And it is not a good idea to suppress it in system headers. (This was originally changed in r134996 to implement -MG.) Fixes <rdar://10041960>. And also brings down the number of warnings without a flag by one :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138842 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-30Allow C99 hexfloats in C++0x mode. This change resolves the standardsDouglas Gregor
collision between C99 hexfloats and C++0x user-defined literals by giving C99 hexfloats precedence. Also, warning about user-defined literals that conflict with hexfloats and those that have names that are reserved by the implementation. Fixes <rdar://problem/9940194>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138839 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-27Take an entirely different approach to handling the "parsing" ofDouglas Gregor
__import__ within the preprocessor, since the prior one foolishly assumed that Preprocessor::Lex() was re-entrant. We now handle __import__ at the top level (only), after macro expansion. This should fix the buildbot failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138704 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-26Introduce support for a simple module import declaration, whichDouglas Gregor
loads the named module. The syntax itself is intentionally hideous and will be replaced at some later point with something more palatable. For now, we're focusing on the semantics: - Module imports are handled first by the preprocessor (to get macro definitions) and then the same tokens are also handled by the parser (to get declarations). If both happen (as in normal compilation), the second one is redundant, because we currently have no way to hide macros or declarations when loading a module. Chris gets credit for this mad-but-workable scheme. - The Preprocessor now holds on to a reference to a module loader, which is responsible for loading named modules. CompilerInstance is the only important module loader: it now knows how to create and wire up an AST reader on demand to actually perform the module load. - We search for modules in the include path, using the module name with the suffix ".pcm" (precompiled module) for the file name. This is a temporary hack; we hope to improve the situation in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138679 91177308-0d34-0410-b5e6-96231b3b80d8
