Owen Anderson 5aa4f2a085 Add support to GVN for performing sret return slot optimization. This means that, if an sret function tail calls ... another sret function, it should pass its own sret parameter to the tail callee, allowing it to fill in the correct return value. llvm-gcc does not emit this by default. Instead, it allocates space in the caller for the sret of the tail call and then uses memcpy to copy the result into the caller's sret parameter. This optimization detects and optimizes that case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47265 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-18 09:24:53 +00:00
