People keep saying that here from time to time. You said it earlier this year, but despite trying quite hard I've never been able to reproduce such horrible reasons anywhere. I sent you some results of my tests, see http://gcc.gnu.org/ml/gcc/2013-01/msg00142.html and the whole discussion surrounding it, but you did not reply. I really don't think further changes to the stabs support should be made at this point, other than a full re-write to mimic the DWARF model of representing the debug info internally somehow and only emit it at the end. That would make it compatible again with PCH and LTO, and would *finally* make the front ends not dependent on asm target hooks/macros. It's even been suggested to internally represent everything as DWARF and to write a dwarf-to-stabs debug emitter. Ciao! Steven
