Teach PopCleanupBlock to correctly handle the possibility of branching through a EH-only cleanup as part of a fallthrough branch-through. That this happens for this test case is actually a separate bug. llvm-svn: 115668

When instantiating a new-expression, force a rebuild if there were default arguments in either the placement or constructor arguments. This is important if the default arguments refer to a declaration or create a temporary. llvm-svn: 115700

Convert Clang over to resuming from landing pads with llvm.eh.resume. It's quite likely that this will explode, but I need to know how. :) llvm-svn: 132269

Whenever explicitly activating or deactivating a cleanup, we 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. llvm-svn: 144276

Mark C++ reference parameters as dereferenceable Because references must be initialized using some evaluated expression, they must point to something, and a callee can assume the reference parameter is dereferenceable. Taking advantage of a new attribute just added to LLVM, mark them as such. Because dereferenceability in addrspace(0) implies nonnull in the backend, we don't need both attributes. However, we need to know the size of the object to use the dereferenceable attribute, so for incomplete types we still emit only nonnull. llvm-svn: 213386
