llvm dev - Jul 2008 - [LLVMdev] Random extra stuff after compiled functions

Hi all,

When I've been disassembling JIT-compiled functions I've noticed they
all have the same three random instructions after them:

  bns-    cr5,0xd04bbfe8
  stfs    f10,-16404(r3)
  stfs    f10,-16404(r3)

Is this meant to be there?

Cheers,
Gary

It could be stubs, data in text sections. Jump tables, constant pools,  
etc.? Are they ever executed?

Almost certainly data not code.  What are they in hex?
