For PowerPCs how do you find out the TOC address or the SDA address? Like for example in this case.

1 Answer 1


SDA is r13, and it changes very rarely. So finding any assignment to r13 will solve the problem for SDA.

Specifically for the referred example it was

lis       r13, 1        # Load Immediate Shifted
addi      r13, r13, -0x2BF0 # 0xD410 # Add Immediate
  • Thanks! About the TOC any hint?

  • @amgnet: same but with r2 instead of r13

  • Thank you. I noticed more r2 loading references than r13 which is clearly one or 2 maximum. I would assume it should be also nearby? Is this the Global TOC right ?
