Not quite. ARM puts constant pools inline with the code, not in rodata. This 
is a fairly fundamental property of the arm architecture. Unlike most other 
risc architectures arm does not really have any other mechanism for loading 
addresses/large values.  Dyngen has a nontrivial amount of special code to 
handle this.
