C++ interpreter question

[Gary Benson]

Hi all,

The C++ interpreter is full of references to the following methods:

  expr_index_at
  expr_tag_index_at
  local_index_at
  local_tag_index_at

The existing platform-specific interpreter_<arch>.hpp files contain
these methods:

  expr_offset_in_bytes
  expr_tag_offset_in_bytes

I'm guessing something was refactored after the ia64 port was
dropped.  Does anyone know how the old methods relate to the
new ones?

Cheers,
Gary
