[rvm-research] Addressing modes

[Priyanka B. <bha...@gm...>]

Hi,
I am working on jikes and I am trying to find some trace of java program
being executed by jikes rvm. For this purpose I have done some
instrumentation in the code array. And the instrumentation just includes
one Push and one Pop operation.  I have made all this changes in
Assembler.in and genAssembler.sh. This instrumentation is running fine for
almost all the addressing modes except for Reg_RegIdx. In this addressing
mode it is giving Null pointer exception. Could you please tell what is the
dependence of code array and the addressing modes? And the instrumentation
has nothing to do with the addressing mode what might be the cause of Null
pointer exception?
