This violates the ABI (that area is "reserved"), and while it is safe if all code is generated with current compilers, there is some very old code around that uses that slot for something else, and breaks if it is stored into. Adjust testcases looking for current behavior. I've verified that the stack frame size is right in all testcases, whether it changed or not. 7311323. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89811 91177308-0d34-0410-b5e6-96231b3b80d8
