After some extra work, I have got gcc-3.3.2 to generate dwarf information
for my binary. However, I could not find instructions on how to statically
get the variable an instruction is accessing. Like before I could use gdb
to get a line number for a given VPC of an instruction. But I don't know what
options to use to query dwarfdump to get this information.

Am I missing something here? Again, your help is greatly appreciated.

Again, I am stuck to static analysis. I can't stop the program at specific
PC and query the variable.
