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. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139987 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).

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.

2011-08-31objective-c - This patch buffers method implementations Fariborz Jahanian
and does the Sema on their body after the entire class/category @implementation is seen. This change allows messaging of forward private methods, as well as, access to synthesized ivars of properties with foward synthesize declarations; among others. In effect, this patch removes several restrictions placed on objective-c due to in-place semantics processing of methods.

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

2011-08-09Thread Safety: Added basic argument parsing for all new attributes.Caitlin Sadowski
This patch special cases the parser for thread safety attributes so that all attribute arguments are put in the argument list (instead of a special parameter) since arguments may not otherwise resolve correctly without two-token lookahead. This patch also adds checks to make sure that attribute arguments are lockable objects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137130 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-06Properly implement the scope restriction on the NRVO forDouglas Gregor
throw-expressions, such that we don't consider the NRVO when the non-volatile automatic object comes from outside the innermost try scope (C++0x [class.copymove]p13). In C++98/03, our ASTs were incorrect but it didn't matter because IR generation doesn't actually apply the NRVO here. In C++0x, however, we were moving from an object when in fact we should have copied from it.

2011-04-24Implement a new identifier-classification scheme where SemaDouglas Gregor
performs name lookup for an identifier and resolves it to a type/expression/template/etc. in the same step. This scheme is intended to improve both performance (by reducing the number of redundant name lookups for a given identifier token) and error recovery (by giving Sema a chance to correct type names before the parser has decided that the identifier isn't a type name). For example, this allows us to properly typo-correct type names at the beginning of a statement: t.c:6:3: error: use of undeclared identifier 'integer'; did you mean 'Integer'? integer *i = 0; ^~~~~~~ Integer t.c:1:13: note: 'Integer' declared here typedef int Integer; ^ Previously, we wouldn't give a Fix-It because the typo correction occurred after the parser had checked whether "integer" was a type name (via Sema::getTypeName(), which isn't allowed to typo-correct) and therefore decided to parse "integer * i = 0" as an expression. By typo-correcting earlier, we typo-correct to the type name Integer and parse this as a declaration. Moreover, in this context, we can also typo-correct identifiers to keywords, e.g., t.c:7:3: error: use of undeclared identifier 'vid'; did you mean 'void'? vid *p = i; ^~~ void and recover appropriately. Note that this is very much a work-in-progress. The new Sema::ClassifyName is only used for expression-or-declaration disambiguation in C at the statement level. The next steps will be to make this work for the same disambiguation in C++ (where functional-style casts make some trouble), then push it further into the parser to eliminate more redundant name lookups. Fixes <rdar://problem/7963833> for C and starts us down the path of <rdar://problem/8172000>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130082 91177308-0d34-0410-b5e6-96231b3b80d8
