Um, no I can't see. I guess I need to go and read up on DWARF formats. Any good recommended links? A quick google gives me: http://en.wikipedia.org/wiki/DWARF http://wiki.dwarfstd.org/index.php?title=Dwarf_FAQ http://www.eagercon.com/dwarf/dwarf-2.0.0.pdf Is this what you recommend reading? Or is there better documentation? -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
