Assuming it bakes OK on the mainline, I would like this patch for 4.0.
Eventually GDB will use DWARF-2 unwind information on PPC; the longer
GCC generates bad unwind information, the harder it will be to adapt
GDB. So I have high motivation to see 4.0.1 fixed.
It's probably going to require a gruesome unwinding hack anyway.
