Arnold Schwaighofer 9265275a9a Mark the return address stack slot as mutable when moving the return address ... during a tail call. A parameter might overwrite this stack slot during the tail call. The sequence during a tail call is: 1.) load return address to temp reg 2.) move parameters (might involve storing to return address stack slot) 3.) store return address to new location from temp reg If the stack location is marked immutable CodeGen can colocate load (1) with the store (3). This fixes bug 6225. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96783 91177308-0d34-0410-b5e6-96231b3b80d8		2010-02-22 16:18:09 +00:00
