2011-08-09Move the creation of the record type for the state of Objective-C fastDouglas Gregor
enumerations from the ASTContext into CodeGen, so that we don't need to serialize it to AST files. This appears to be the last of the low-hanging fruit for SpecialTypes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137124 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Move the construction of the RecordDecl representing the runtimeDouglas Gregor
layout of a constant NSString from the ASTContext over to CodeGen, since this is solely CodeGen's responsibility. Eliminates one of the unnecessary "special" types that we serialize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137121 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-07Avoid fallthrough-branching to an inactive cleanup even if it'sJohn McCall
otherwise required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137029 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-06Be sure to destroy the normal entry block of a cleanup that weJohn McCall
aren't actually going to make a normal cleanup for. Sometimes we optimistically create branches to such blocks for fixups, and then we resolve the fixup to somewhere within the cleanup's scope, and then the cleanup is actually not reachable for some reason. The process of resolving the fixup leaves us with switches whose default edge leads to the cleanup; we can replace that with unreachable, then (in many cases) turn the switch into an unconditional branch. Fixes PR10467. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137011 91177308-0d34-0410-b5e6-96231b3b80d8

own, incorrectly, for releasing objects at the end of a full-expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136823 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-03Handle "homogeneous aggregates" as required by the ARM AAPCS-VFP ABI.Bob Wilson
A homogeneous aggregate is an aggregate data structure where after flattening any nesting there are 1 to 4 elements of the same base type that is either a float, double, or Neon vector. All Neon vectors of the same size, either 64 or 128 bits, are treated as equivalent for this purpose. When using the AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by expanding them into a sequence of their base types. This requires extending the existing support for expanded arguments to handle not only structs, but also constant arrays and complex types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136767 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-01Revert "Re-enable byval for ARM in clang. rdar://problem/7662569"Bob Wilson
This reverts commit 67d097e1232b7d66f58989c16a45b8a11721f76e. We found a miscompile with ARM byval, which is still being investigated. In the meantime, this works around the problem by disabling ARM byval.

2011-07-28Fix a couple of problems with initialization and assignment toJohn McCall
__block variables where the act of initialization/assignment itself causes the __block variable to be copied to the heap because the variable is of block type and is being assigned a block literal which captures the variable. rdar://problem/9814099 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136337 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-27Clean up the analysis of the collection operand to ObjCJohn McCall
for-in statements; specifically, make sure to close over any temporaries or cleanups it might require. In ARC, this has implications for the lifetime of the collection, so emit it with a retain and release it upon exit from the loop. rdar://problem/9817306 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136204 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26Disable the optimization that skips emission of complete, non-virtualDouglas Gregor
destructors of abstract classes. It's undefined behavior to actually call the destructor (e.g., via delete), but the presence of code that calls this destructor doesn't make the program ill-formed.

their loaded values, although it still worth doing this for __weak properties to get the autoreleased-return-value optimization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135747 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-22Add a const overload for ObjCInterfaceDecl::all_declared_ivar_begin.Jordy Rose
This was previously not-const only because it has to lazily construct a chain of ivars the first time it is called (and after the chain is invalidated). In practice, all the clients were just const_casting their const Decls; all those now-unnecessary const_casts have been removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135741 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-20fix rdar://9780211 - Clang crashes with an assertion failure building ↵Chris Lattner
WKView.mm from WebKit This is something of a hack, the problem is as follows: 1. we instantiate both copied of RetainPtr with the two different argument types (an id and protocol-qualified id). 2. We refer to the ctor of one of the instantiations when introducing global "x", this causes us to emit an llvm::Function for a prototype whose "this" has type "RetainPtr<id<bork> >*". 3. We refer to the ctor of the other instantiation when introducing global "y", however, because it *mangles to the same name as the other ctor* we just use a bitcasted version of the llvm::Function we previously emitted. 4. We emit deferred declarations, causing us to emit the body of the ctor, however the body we emit is for RetainPtr<id>, which expects its 'this' to have an IR type of "RetainPtr<id>*". Because of the mangling collision, we don't have this case, and explode. This is really some sort of weird AST invariant violation or something, but hey a bitcast makes the pain go away. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135572 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-20as eli points out, we're not doing memory stuff here. While ConvertType Chris Lattner
