[PATCH] [PATCH] Fix for http://llvm.org/bugs/show_bug.cgi?id=19905

[Vadim Chugunov]

@sanjoy, I wonder what happens with your patch in case of stack re-alignment.
Sorry, I can't figure out how to get git to apply your diff.  Could you please try it on the following IR:

    declare void @llvm.eh.unwind.init()

    define coldcc void @calls_unwind_init() {
      %s = alloca i32, align 64
      call void @llvm.eh.unwind.init()
      ret void
    }

If CFI info for XMM registers still correct?
