[LLVMdev] Transforming ConstantExprs to Instructions

Hi Chris,

I meant the other way around. Ie,

@A = internal global { i32, i32 }
%B = load getelementptr { i32, i32 }* @A, i32 0, i32 0

would trivially translate to

%A = alloca { i32, i32 }
%B = load getelementptr { i32, i32 }* %A, i32 0, i32 0

which is not legal AFAICS (since %A is not a Constant).
