Linker question

["Sumesh UdayaKumaran" <sumesh_uk@hotmail.com>]

Hi
   As part of a project Iam involved in, I need to maintain copies of the 
same variable in different memory banks (kind of like cache). I then want to 
based on criteria I have address the different copies at different program 
points.

             Eg            ldw r3,A ....................Address the copy of 
global variable A in bank1.

                             ..................

                            ................
                           ldw r4, A            Address the copy of global 
variable A in bank2



Iam implementing this on a gcc cross compiler for mcore-elf.

From what I have figured so far (Iam really new to this whole world of 
linking and assembling ), I can handle this at the stage when the exact 
addresses are being generated.

The questions I had were:
1. Where is the exact address being generated.
2. As an alternative , can I handle such a scheme through a script, in other 
words can the script be used to guide such an addressing.


Any pointers, suggestions will be great


thanks
sumesh
