* Remove more unnecessary #include <llvm/ADT/SmallVector.h>Francois Pichet2011-06-201-1/+0

* Update to match mainline ConstantStruct::get API change. Also, use Chris Lattner2011-06-207-59/+60
| | | | | | | | | | | ConvertType on InitListExprs as they are being converted. This is needed for a forthcoming patch, and improves the IR generated anyway (see additional type names in testcases). This patch also converts a bunch of std::vector's in CGObjCMac to use C arrays. There are a ton more that should be converted as well. llvm-svn: 133413

* When emitting a compound literal of POD type, continue to emit aDouglas Gregor2011-06-171-0/+10
| | | | | | | | | | | | | | | | | separate aggregate temporary and then memcpy it over to the destination. This fixes a regression I introduced with r133235, where the compound literal on the RHS of an assignment makes use of the structure on the LHS of the assignment. I'm deeply suspicious of AggExprEmitter::VisitBinAssign()'s optimization where it emits the RHS of an aggregate assignment directly into the LHS lvalue without checking whether there is any aliasing between the LHS/RHS. However, I'm not in a position to revisit this now. Big thanks to Eli for finding the regression! llvm-svn: 133261

* Objective-C fast enumeration loop variables are not retained in ARC, butJohn McCall2011-06-173-7/+47
| | | | | | | | | | | | they should still be officially __strong for the purposes of errors, block capture, etc. Make a new bit on variables, isARCPseudoStrong(), and set this for 'self' and these enumeration-loop variables. Change the code that was looking for the old patterns to look for this bit, and change IR generation to find this bit and treat the resulting variable as __unsafe_unretained for the purposes of init/destroy in the two places it can come up. llvm-svn: 133243
* Implement proper support for generating code for compound literals inDouglas Gregor2011-06-171-3/+8
| | | | | | | | | | | | | C++, which means: - binding the temporary as needed in Sema, so that we generate the appropriate call to the destructor, and - emitting the compound literal into the appropriate location for the aggregate, rather than trying to emit it as a temporary and memcpy() it. Fixes PR10138 / <rdar://problem/9615901>. llvm-svn: 133235

* The LLVM IR representation of byval arguments has a rather strange property: ↵Eli Friedman2011-06-141-5/+44
| | | | | | | | | | if the alignment of an argument to a call is less than the specified byval alignment for that argument, there is no way to specify the alignment of the implied copy. Therefore, we must ensure that the alignment of the argument is at least the byval alignment. To do this, we have to mess with the alignment of relevant alloca's in some cases, and insert a copy that conceptually shouldn't be necessary in some cases. This patch tries relatively hard to avoid creating an extra copy if it can be avoided (see test3 in the included testcase), but it is not possible to avoid in some cases (like test2 in the included testcase). rdar://9483886 llvm-svn: 132957

* Implement Objective-C Related Result Type semantics.Douglas Gregor2011-06-111-23/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Objective-C doesn't consider the use of incomplete types as methodDouglas Gregor2011-05-271-2/+23
| | | | | | | | | | | | | | parameter types to be ill-formed. However, it relies on the completeness of method parameter types when producing metadata, e.g., for a protocol, leading IR generating to crash in such cases. Since there's no real way to tighten down the semantics of Objective-C here without breaking existing code, do something safe but lame: suppress the generation of metadata when this happens.
