Bill Wendling	f92cb857aa	MorphNodeTo doesn't preserve the memory operands. Because we're morphing a node ... into the same node, but with different non-memory operands, we need to replace the memory operands after it's finished morphing. llvm-svn: 106643	2010-06-23 18:16:24 +00:00
Arnold Schwaighofer	8427969f9c	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. llvm-svn: 96783	2010-02-22 16:18:09 +00:00
