Does anyone know if the format of the stack frame when a signal occurs is documented anywhere? I've found the code in http://lxr.linux.no/source/arch/ppc /kernel/signal.c, and I can get most of it from that; but there are some strangenesses there I don't understand (why is there more than one sigcontext structure? What's sys_sigreturn *doing*?). The format doesn't seem to be documented in the PPC ABI.
My next step is to get out ddd and start fiddling with it; but I'd really rather not do that. If anyone here knows, I'd be extremely grateful. -- +- David Given ---------------McQ-+ "[SF is not about predicting the future.] | Work: [EMAIL PROTECTED] | We are not prophets; in fact, if we were | Play: [EMAIL PROTECTED] | much worse at it, we'd be economists." --- +- http://wired.st-and.ac.uk/~dg -+ Stephen Dedman
