Hi,
The orphan section warning patch had a minor issue with unhandled
.text.save.restore last time I sent it. I went back and tidied up
crtsavres a bit, so after these, I think we can enable orphan section
warnings.
There is a further step we can take which is to enable
--save-restore-funcs for module link, which means 64-bit does not
need crtsavres at all. That option is only in binutils 2.25 though,
so I'll send that later.
Thanks,
Nick
