Owen Anderson 6bb0bd52ec Improve the return slot optimization to be both more aggressive (not limited to sret parameters), and ... safer (when the passed pointer might be invalid). Thanks to Duncan and Chris for the idea behind this, and extra thanks to Duncan for helping me work out the trap-safety. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48280 91177308-0d34-0410-b5e6-96231b3b80d8		2008-03-12 07:37:44 +00:00
