2011-11-10Whenever explicitly activating or deactivating a cleanup, weJohn McCall
need to provide a 'dominating IP' which is guaranteed to dominate the (de)activation point but which cannot be avoided along any execution path from the (de)activation point to the push-point of the cleanup. Using the entry block is bad mojo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144276 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-10Fix a subtle bug with cleanups: when activatingJohn McCall
a previously-inactive cleanup, not only do we need a flag variable, but we should also force the cleanup to query the flag variable. However, we only need to do this when we're activating in a context that's conditionally executed; otherwise, we may safely assume that the cleanup is dominated by the activation point. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144271 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-10Enter the cleanups for a block outside the enclosingJohn McCall
full-expression. Naturally they're inactive before we enter the block literal expression. This restores the intended behavior that blocks belong to their enclosing scope. There's a useful -O0 / compile-time optimization that we're missing here with activating cleanups following straight-line code from their inactive beginnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144268 91177308-0d34-0410-b5e6-96231b3b80d8

the other helper functions, since we already differentiated the cases it was testing between. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144167 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-09Emit the copy and dipose helpers for ARC __strongJohn McCall
block-typed __block variables using objc_retainBlock and objc_dispose. Previously we were using _Block_object_assign and _Block_object_destroy with BLOCK_BYREF_CALLER, which causes the runtime to completely ignore the retain and release. In most cases this doesn't cause catastrophe because the retain/release are balanced and because the block in the variable was copied upon assignment there. However, the stack copy of the variable will be released when it goes out of scope, which is a problem if that value was released due to an assignment to the heap copy. Similarly, a leak can occur if the variable is assigned after the copy to the heap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144162 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-08Clean up type flags for overloaded Neon builtins. No functional change.Bob Wilson
This patch just adds a simple NeonTypeFlags class to replace the various hardcoded constants that had been used until now. Unfortunately I couldn't figure out a good way to avoid duplicating that class between clang and TableGen, but since it's small and rarely changes, that's not so bad. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144054 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Change the AST representation of operations on Objective-CJohn McCall
property references to use a new PseudoObjectExpr expression which pairs a syntactic form of the expression with a set of semantic expressions implementing it. This should significantly reduce the complexity required elsewhere in the compiler to deal with these kinds of expressions (e.g. IR generation's special l-value kind, the static analyzer's Message abstraction), at the lower cost of specifically dealing with the odd AST structure of these expressions. It should also greatly simplify efforts to implement similar language features in the future, most notably Managed C++'s properties and indexed properties. Most of the effort here is in dealing with the various clients of the AST. I've gone ahead and simplified the ObjC rewriter's use of properties; other clients, like IR-gen and the static analyzer, have all the old complexity *and* all the new complexity, at least temporarily. Many thanks to Ted for writing and advising on the necessary changes to the static analyzer. I've xfailed a small diagnostics regression in the static analyzer at Ted's request. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143867 91177308-0d34-0410-b5e6-96231b3b80d8
