[LLVMdev] Spilled variables using unaligned moves
Hi all,
It looks like vector spills don't use aligned moves even though the stack is

The attached replacement of fibonacci.cpp generates x86 code like this:
03A70010 push ebp
03A70011 mov ebp,esp
03A70013 and esp,0FFFFFFF0h
03A70019 sub esp,1A0h
...
03A7006C movups xmmword ptr
