Arnold Schwaighofer 865c68188a Change the lowering of arguments for tail call optimized ... calls. Before arguments that could overwrite each other were explicitly lowered to a stack slot, not giving the register allocator a chance to optimize. Now a sequence of copyto/copyfrom virtual registers ensures that arguments are loaded in (virtual) registers before they are lowered to the stack slot (and might overwrite each other). Also parameter stack slots are marked mutable for (potentially) tail calling functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47593 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-26 09:19:59 +00:00
