Description Stefan Oberhumer 2011-01-20 14:03:29 UTC 
Running objdump --dwarf can result in an outputline where hex and decimal is
mixed - eg:
  DW_CFA_advance_loc: 11 to 0000000f

where "11" is decimal and "0000000f" hex.


Seems this happen for:
  DW_CFA_advance_loc
  DW_CFA_set_loc
  DW_CFA_advance_loc1
  DW_CFA_advance_loc2
  DW_CFA_advance_loc4
  DW_CFA_MIPS_advance_loc8

I misinterpreted the output.
