* Implement Objective-C Related Result Type semantics.Douglas Gregor2011-06-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | ObjC NeXt runtime where method pointer registered in metadata belongs to an unrelated method. Ast part of this fix, I turned at @end missing warning (for class implementations) into an error as we can never be sure that meta-data being generated is correct. // rdar://9072317 llvm-svn: 130019

| | | | | | | | | AttributeLists do not accumulate over the lifetime of parsing, but are instead reused. Also make the arguments array not require a separate allocation, and make availability attributes store their stuff in augmented memory, too. llvm-svn: 128209

| | | | | | | | | | | ActOnFinishFunctionBody/ActOnBlockStmtExpr. This way, we ensure that we diagnose undefined labels before the jump-scope checker gets run, since the jump-scope checker requires (as its invariant) that all of the GotoStmts be wired up correctly. Fixes PR9495. llvm-svn: 127738

* Refactor how we collect attributes during parsing, and add slots for attributesJohn McCall2010-12-241-24/+32

* Fix a major inconsistency in the representation of Objective-CDouglas Gregor2010-12-211-9/+4
| | | | | | | | | | | | | | | | | | | | classes, categories, protocols, and class extensions, where the methods and properties of these entities would be inserted into the DeclContext in an ordering that doesn't necessarily reflect source order. The culprits were Sema::ActOnMethodDeclaration(), which did not perform the insertion of the just-created method declaration into the DeclContext for these Objective-C entities, and Sema::ActOnAtEnd(), which inserted all method declarations at the *end* of the DeclContext. With this fix in hand, clean up the code-completion actions for property setters/getters that worked around this brokenness in the AST. Fixes <rdar://problem/8062781>, where this problem manifested as poor token-annotation information, but this would have struck again in many other places. llvm-svn: 122347

* Region-allocate all AttributeList objects from a factory object instead of ↵Ted Kremenek2010-11-101-15/+6
| | | | | | | | | | | | | | | | | | | | | | | | manually managing them using new/delete and OwningPtrs. After memory profiling Clang, I witnessed periodic leaks of these objects; digging deeper into the code, it was clear that our management of these objects was a mess. The ownership rules were murky at best, and not always followed. Worse, there are plenty of error paths where we could screw up. This patch introduces AttributeList::Factory, which is a factory class that creates AttributeList objects and then blows them away all at once. While conceptually simple, most of the changes in this patch just have to do with migrating over to the new interface. Most of the changes have resulted in some nice simplifications. This new strategy currently holds on to all AttributeList objects during the lifetime of the Parser object. This is easily tunable. If we desire to have more bound the lifetime of AttributeList objects more precisely, we can have the AttributeList::Factory object (in Parser) push/pop its underlying allocator as we enter/leave key methods in the Parser. This means that we get simple memory management while still having the ability to finely control memory use if necessary. Note that because AttributeList objects are now BumpPtrAllocated, we may reduce malloc() traffic in many large files with attributes. This fixes the leak reported in: <rdar://problem/8650003> llvm-svn: 118675

* Refactor code completion for expressions that occur as arguments inDouglas Gregor2010-09-201-6/+36
| | | | | | | | Objective-C message sends. There is no functionality change here; this is prep work for using the parameter types to help guide the expression results when code-completing the argument. llvm-svn: 114375
* Implement automatic bracket insertion for Objective-C class messageDouglas Gregor2010-09-161-0/+29
| | | | | | | | | | | | | | | | sends. These are far trickier than instance messages, because we typically have something like NSArray alloc] where it appears to be a declaration of a variable named "alloc" up until we see the ']' (or a ':'), and at that point we can't backtrace. So, we use a combination of syntactic and semantic disambiguation to treat this as a message send only when the type is an Objective-C type and it has the syntax of a class message send (which would otherwise be ill-formed). llvm-svn: 114057

* Implement bracket insertion for Objective-C instance message sends asDouglas Gregor2010-09-151-0/+7
| | | | | | | | | | | | | | | | | | | | | | | part of parser recovery. For example, given: a method1:arg]; we detect after parsing the expression "a" that we have the start of a message send expression. We pretend we've seen a '[' prior to the a, then parse the remainder as a message send. We'll then give a diagnostic+fix-it such as: fixit-objc-message.m:17:3: error: missing '[' at start of message send expression a method1:arg]; ^ [ The algorithm here is very simple, and always assumes that the open bracket goes at the beginning of the message send. It also only works for non-super instance message sends at this time. llvm-svn: 113968
