[Dwarf-Discuss] DWARF expression evaluation

Hi,
  I'm trying to evaluate DWARF expressions and I'm looking for a hint
or some documentation about the state of the expression evaluator's
stack prior to beginning the expression.

  The reason I'm asking about this is I'm seeing expressions (a
DW_AT_data_member_location for example) that start with DW_OP_dup,
which implies that there is something on the stack for it to dup.
