Subject: [RFC] Endianness and signals
Date: Mon, 20 Oct 2003 23:42:09 +0000 [thread overview]
Message-ID: <marc-linux-ia64-106669369711349@msgid-missing> (raw)
Further to my study of IA64 architecture, and to an extent the linux kernel,
I wonder if the gate page ought to default to little endian upon issue of a
signal. i.e. "rum 2" prior to any loads/stores? It would seem to me that in
the current state, if the process were preempted immediately after a memory
access (fundamentally) in big-endian mode the signal context would likely
execute in the wrong endianness and fail. - It's my understanding that the
user mask is preserved in the context switch.
Regards,
Richard.
