If you try llvm-gcc from svn trunk then you'll see llvm.dbg.value
intrinsic replacing llvm.dbg.declare intrinsic when alloca is lowered.
However, as others have said, the optimizer does not guarantee that it
will always be able to preserve variable info accurately.

The real question is, why do you want to map tmp to %1 ?
