finding register to variable mapping at a specific address

[Cibu dot Johny at utstar dot com]

Hi,

I would like to know whether it is possible to find the mapping between the
variables and registers at a specific address. As an example please see
following 'objdump' output:

../../src/ppp_stub.c:120
        do_hex_event = FALSE;
  54d394:       3a 40 00 00     li      r18,0
../../src/ppp_stub.c:121
        if (p_link != NULL && p_link->num_traces > 0)
  54d398:       2c 1f 00 00     cmpwi   r31,0
  54d39c:       41 82 00 14     beq-    54d3b0 <ppp_tracepkt+0x4c>
  54d3a0:       81 9f 05 74     lwz     r12,1396(r31)
  54d3a4:       2c 0c 00 00     cmpwi   r12,0
  54d3a8:       40 81 00 08     ble-    54d3b0 <ppp_tracepkt+0x4c>


I would like to know for which variables registers r12 and r31 stands for at the address 54d3a4.

Is this possible at all with binutils? If yes, please let me know how.

thanks,
Cibu
