Thanks (and sorry for the delay), pushed "hurd: libgcc unwinding over
signal trampolines with SIGINFO" to master
Ping?

Do y
When the application sets SA_SIGINFO, the signal trampoline parameters
are different to follow POSIX.

Oups right yes.
Samuel
You seem to be talking about SA_SIGINFO. Please be precise.
You are not talking about SIGINFO at all.
Hello,
I was wondering about implementing SIGINFO: as I understand it, the Hurd
glibc currently calls the signal handlers as
void handler(int signo, long int sigcode, struct sigcontext *scp)
so the basis for the support of the kind of information that SIGINFO
provides is already there, it&#
