Currently, the compiler requires that dereferences be HLSL_IR_CONSTANT, so that it can compute the offset at compile time. However, scenarios such as this test will produce a dereference with HLSL_IR_EXPR, which will generate an error.
Passing this test in particular will require adding support for SM4 relative addressing, as well as support for non-constant indexing in general.
