Richard Smith	f03bd30854	PR17983: Fix crasher bug in C++1y mode when performing a non-global array ... delete on a class which has no array cookie and has no class-specific operator new. llvm-svn: 196488	2013-12-05 08:30:59 +00:00
Richard Smith	b47c36f8e1	C++1y sized deallocation: if we have a use, but not a definition, of a sized ... deallocation function (and the corresponding unsized deallocation function has been declared), emit a weak discardable definition of the function that forwards to the corresponding unsized deallocation. This allows a C++ standard library implementation to provide both a sized and an unsized deallocation function, where the unsized one does not just call the sized one, for instance by putting both in the same object file within an archive. llvm-svn: 194055	2013-11-05 09:12:18 +00:00
Richard Smith	1cdec019e8	Implement C++1y sized deallocation (n3778). This is not enabled by -std=c++1y; ... instead, it's enabled by the -cc1 flag -fsized-deallocation, until we sort out the backward-compatibility issues. llvm-svn: 191629	2013-09-29 04:40:38 +00:00
