- Evaluates an operand using a client-supplied register state accessor.
+ Evaluates an operand using a client-supplied register state accessor.  Register
+ operands are evaluated by reading the value of the register; immediate operands
+ are evaluated by reporting the immediate value; memory operands are evaluated
+ by computing the target address (with only those relocations applied that were
+ already applied to the original bytes).
  @param result A pointer whose target is to be filled with the result of
    evaluating the operand.
  @param operand The operand to be evaluated.
